Vacuum Purge Basics for Premium Homemade BHO


Concentrates have become extremely popular today as the popularity of cannabis in general grows and people discover new ways of enjoying the medicinal and recreational benefits of marijuana. The popularity of concentrates comes from the intensity of the high they are capable of delivering. Butane hash oil (BHO) is made from extracting high concentrations of THC from marijuana flower. It was done for the first time during the 1970s but didn’t really start to grow in popularity until the 2000s. The popularity of extraction has continued to grow since then, especially as more states legalize cannabis and more products become available to make the process of consuming concentrates easier and more enjoyable.

A General Disclaimer About Working with BHO

Keep in mind when working with BHOs that there are extremely flammable and even explosive solvents involved in the process. You have to be careful to keep the space well ventilated and be very careful of flames, spark and heat in general. You want to be very careful to avoid setting off a fireball that could quickly fill the room.

The Importance of a Thorough Vacuum Purge


mastering vacuum purge techniques gives your bho more purity

BHO purity can be improved through mastering vacuum purging techniques.

Part of the process of incorporating concentrates into your life is learning a little about the ins and outs of how they work and what gives them their purity. Unless a vacuum purge is done on a BHO product either before or after purchase, you will have a problematic concentrate on your hands. It’s important to realize that without the purge, some butane will remain in the product which is not what you want to be consuming. The residual gases need to be purged in order to get the high quality BHO you deserve.

BHO That Hasn’t Been Vacuum Purged

If you’re a fan of enjoying concentrates then you know that there is nothing worse than having to consume low quality BHO. It is often grey, tastes foul and is full of nasty stuff that you definitely don’t want to be consuming for your health. This kind of BHO has not been vacuum purged, illustrating the absolute importance of vacuum purging in order to get the best possible quality product for your consumption. When you vacuum purge your BHO, it boils away those nasty elements, solvents and impurities, leaving you with a purer, healthier and better tasting BHO.

The Targeted Atmospheric Pressure

When working to perform an effective vacuum purge, it’s helpful to understand the precise atmospheric pressure for which you’re aiming. The measurement is made through inches of mercury, commonly called inHG. With the levels in the tube or barometer at a setting of 1, the mercury will move up to 29.92 inches. This is the basic atmospheric level we are all experiencing, as it relates to sea level. When we vacuum purge our BHO, we are aiming to create an atmospheric pressure of -29.92 inHG. At this level, the BHO would be devoid of all atmospheric pressure. It’s not an easy measurement to get but this is still what we are aiming for during a vacuum purge.

The Right Vacuum Purging Equipment for Your Purposes

it pays to use top end equipment for your vacuum purge operations

High end equipment can be a worthwhile investment for shatter purification. 

A vacuum purge can be performed in several ways. There is a vast array of vacuum purging equipment available on the market. Of course, the more you are willing to spend, the better the purge is going to be. For those that will be consuming concentrates on a very consistent level, the quality of the purge may warrant that you purchase high quality equipment to use. For others that may be unable to shell out for the vacuum purge equipment, there are many processes for vacuum purging at home. It will take some patience, care and effort but it is more than possible.

Home Vacuum Purging Solutions

Some people have found that they are able to get effective results vacuum purging using equipment that is usually used to preserve food such as a FoodSaver 3460. The issue with this is that it can only go as low as -20 inHG. This means they will certainly improve the quality of the BHO but it won’t be as high a quality since it can’t achieve the desired -29.92 inHG desired result. You could also use a hand pump made for bleeding brake lines if you have a small batch and a small chamber. This technique may even create a lower pressure that could reach closer to -27 inHG.

Creating your Own Vacuum Purge System

You can also just make your own vacuum purge at home by putting together a few critical pieces. You can pick up a readymade vacuum chamber and then run it using a 2 stage vacuum pump. With your vacuum chamber, you want to be absolutely sure that you only use the highest quality silicone in the chamber. Cheap silicone has plasticizers in it that will wreak havoc on your vacuum purge, melting and spoiling your batch. Also be aware that the slightest crack in a glass vacuum chamber could become a problem under the pressure of the pump. Metal may be the best option here. With your 2 stage vacuum pump, you will be aiming for an oilers variety to stop the solvents from getting into the pump and being pulled back down into your concentrate.

The Process of Vacuum Purging in Action


setting up a home vacuum purging system can be easy if you know what youre doing

Setting up a home vacuum purging system can be simple if you know what you’re doing.

Before you start vacuum purging, place your BHO on a Pyrex dish. Place the dish on hot water that doesn’t exceed approximately 140 degrees, the temperature of hot coffee. Gently boil the BHO, scrape up the syrupy substance and place it on your silicone mat, being sure to keep it as thin a layer as possible. Place the silicone mat in the vacuum chamber. You can use parchment paper if the mat is too big. Seal up the chamber now and start pumping, aiming to lower the pressure to anywhere between -27 and -29.92 inHG. Place the chamber on a heating pad and after a few minutes let the air back in the chamber. Then seal the chamber and pump again. Do this until the BHO bubbles. Then allow the BHO to sit for 24 hours. You can repeat the process of creating the thin layer of BHO and vacuum purging it again, allowing it to sit for a few hours. You can also roll it up and put it in the fridge or freezer for a few minutes once it is done to allow it to get firm.

As you can see there are several ways to perform your vacuum purge at home. From Food Savers to hand pumps, there is something that everyone can use. The main focus should be on removing the gas bubbles that arise, which may mean taking a fork or dabber and popping the bubbles in a ventilated space until they are gone. Removing all of the butane may be difficult with a simple home technique but it will still help to make your batch healthier and purer.

THC Dosage for Concentrates Can Be Sticky Business


Dabbing is still such a new phenomenon that dosing can be quite a mystery. While generally speaking, people are told to start with the smallest possible dose, it’s hard to know exactly what that means. Most hash oils come in half gram portions but there’s still no tool to measure a dabbing dose. As consuming concentrates is already an intense experience that produces a powerful high, you don’t want that THC dosage to be any higher than necessary. There are steps you can take as a first timer to ensure that you stay within the limits of what will work best for you.

Read the Label


THC dosage labels are an easy means of figuring the strength of a specific concentrate. 

It may seem obvious but the first step is to read the label carefully. Most concentrate packaging makes an attempt to indicate how strong it is as well as give you a bit of a profile of your concentrate. There is usually information about THC content either in percentages or in milligrams. Sometimes they will also give you a terpenoid profile that allows you to get even more of an understanding of what flavor and effects your concentrate will have. The ratio of THCA to THC is usually given as well so that you can estimate the best THC dosage for you.


Estimating Cannabinoid Percentages

Most solvent based hash oils have between 60-90 percent cannabinoids with very few going higher than 90 percent although some solventless concentrates can have less than 50 percent. So what do these percentages mean? If your concentrate says it contains 60 percent, that means for every one gram it contains 600mg. If it says it contains 90 percent, that means every one gram it contains 900mg. It’s good to keep in mind that when consuming edibles, beginners are recommended to start with anything between 5-10 percent. Based on that, it’s important to start with the lowest dose possible.

Selecting the Right Dab Tool

finding the write dab tool essential to accurate thc dosage portioning

The right dab tool will make portioning concentrates easier.

The next thing you need to think about is what tool you will use for portioning your dose. There is absolutely no rule for this. There are an endless amount of dabber tools that exist in all kinds of shapes and sizes. The only thing that matters is how easy it is for you to use. A pointed dabber might be hard to use for portioning and a scooper doesn’t work very well with trying to break apart shatter. Generally speaking, dabbers with broader tips are the most versatile. These can generally handle concentrates in all kinds of consistency and give you more control.

Portioning Your Concentrates

Estimating what portion to start with is more a matter of math than anything else. If your concentrate contains 60 percent cannabinoid content, that means it contains 600mg in every gram. So if you take one gram and split it into six portions, then you know you’ll be consuming 100mg in each dosage. If you split it into twelve portions then you know you’d be consuming 50mg in every dose. The ease in which this is done depends on the consistency of your concentrate. If you need to divide a shatter, then heating your dabbing tool is all that’s necessary for splitting it up with ease.

Ways Around Portioning

Portioning can be a bit of a tricky process and you may not want to deal with the math, the mess or divisions. If this is the case for you there are other options. Vaporizer cartridges are already divided and measured for you. These give you an easy delivery method for knowing exactly what you’re getting. Free form hash oil cartridges give you more control and reduce the likelihood of having too much. They come in single hit options and they often give you a clear indication of how many hits each cartridge provides. This makes the process of getting the right THC dosage a no-brainer.

The Importance of an Accurate THC Dosage

when handling shatter accurate thc dosage is important

Accurate THC dosage is integral to patients. 

THC is the psychoactive ingredient in marijuana that may cause you to have a nightmarish experience if you have too much but it’s also the compound that will make you feel high in the first place. Since it’s the ingredient that will make you laugh, feel creative and euphoric, being sure to have a decent THC dosage is important but having too much will make you so high that anxiety, paranoia and other nasty effects can result. This makes checking the labels and dosage of your hit an important affair. You want the best experience and there is no rule for what dosage is best for everyone.

Staying Aware of Your Personal Chemistry

People’s bodies are different and as a result a THC dosage will affect everyone in a different way. A 25mg hit may feel very different based on your personality, psychology and body type. For this reason, it’s very important to start with a smaller dose. In fact, the smaller the dosage the better. You can always work up to a comfortable amount but you can’t work down once you’ve consumed too much. You will never be disappointed by consuming less as you can always have more. At that point, you can experiment to discover what the best dosage is for you.

What to Do If You Accidentally Have Too Much

If you do happen to consume too high of a dose for you, there are some simple things you can do. Firstly, don’t panic. The key with dealing with the anxiety that can come from a high dosage is staying calm. You will want to try and relax as much as possible. You may even want to lie down and recover before doing anything else. A shower or bath can also help you to maintain some peace. Play music or put on a T.V. show or film that relaxes you. Make sure you drink plenty of water and make sure to eat some nourishing food. Another trick that many people swear by is sniffing or chewing on black pepper! Many, including Neil Young, claim that this remedy almost immediately relives anxiety and paranoia. CBD oil may also be able to help since it combats anxiety and can balance out a high THC dosage.

If you follow these steps and experiment starting with the smallest possible dosage, you will no doubt find the best THC dosage for you.


Dab Nail Types Offer Different Dabbing Experiences


Dabbing is a fairly new trend in weed consumption that’s still new to even the most experienced pot smokers. The incredible high boasted has left many a novice chomping at the bit to experience this latest craze. But before you can get too carried away, it’s good to really understand what the difference is between each dab nail so that you can know what you’re getting into.

The Importance of Choosing the Right Dab Nail Material

This list explores the many varieties of dab nails and their pros and cons, from glass nails to an electric rig. The key factors to keep in mind when choosing a dab nail are taste and durability. You also want to get an idea of how fast a nail can be heated and how long it will stay hot. All of these things contribute to the ease and quality of your hit. Marijuana concentrates can be quite pricey and you don’t want your precious oil to go to waste so proper use of your dab rig is important and choosing a dab nail that you’re comfortable with is essential.

Glass Nails

The first dab nail we’ll examine today is the glass nail. Most rigs you buy will come with a glass nail. These nails produce a great flavor and they’re easy to clean. The main issue is that they don’t withstand heat well which also means they are a little tricky to heat. Heating your glass nail must be done slowly and with caution; otherwise they can break. This brings us to the general problem with all glass marijuana paraphernalia: they are incredibly easy to break. Generally speaking, however, you can always count on a glass nail to deliver a pleasant taste.

Ceramic Nails

Ceramic nails typically offer delicious tasting dabbing sessions though some frequent dabbers have complained about ceramic’s tendency to give off a somewhat overcooked taste.  One of the benefits of ceramic nails lies in their ability to stay hot longer so you can have multiple hits in a session without reigniting your torch. Ceramic is attractive and easy to clean but can also be very fragile. Like the glass dab nail, they may take longer to heat up and it may be more challenging to get them to heat evenly.


Quartz Nails

Now we get into a higher quality domain. The quartz dab nail is much more durable than the previous types described. The quartz nail has similar benefits to the glass dab nail only it is much more durable and can withstand higher amounts of heat. The flavor offered by quartz is as good and clean as the flavor gets. It’s only down side is it cools off very rapidly so you have to be quick when using a quartz nail. Generally speaking, quartz presents a reliable dab nail with delicious flavor.

Titanium Nails or “TI” Nails

domeless titanium dab nails are indestructible

Titanium nails are considered indestructible when compared to other materials. 

The titanium dab nail (also referred to simply as a TI nail) is another top of the range option. Titanium can withstand a lot of heat and also has great heat transfer. You must make sure that the dab nail you get is medical grade 2 titanium. Other types of titanium dab nails can be found on the market but they can be made with a lot of filler which leads to a bad taste. Because this dab nail can withstand a lot of heat, it doesn’t create the harsh or toxic fumes linked to other materials. They only take 15-20 seconds to heat up and then they stay warm longer once they’re heated. Best of all, they are indestructible. The only downside is that the taste can be a little metallic sometimes. Otherwise, titanium nails are a good choice for people that want something durable and easy to use.


Electronic Nails or E-nails

Electronic nails, often called e-nails, are the absolute top of the range dabbing apparatus to use but they come at quite a cost. These usually come equipped with a quartz or titanium dab nail and you don’t need to use a torch to heat them yourself as the heating mechanism comes built into it. For this reason, you can’t overheat or burn the oil and it allows you to choose your temperature so you can choose to do a low temperature dab which will allow you take in the full terpene expression. The downside to these is that they’re expensive, maybe running you up to a couple of hundred dollars. They’re also bulky which is not good for discretion or dab rigs that you use for their portable convenience.

Domed vs. Domeless Nails

domeless quartz dab nails heat up fastThe next thing to discuss when it comes to dab nails are the domed and domeless options. The first thing to understand is that the domeless nails already have ventilation holes built into them. They have good built in airflow and therefore don’t need any added pieces. On the other hand, the domed nails require an extra piece called a glass “dome” or a “hood” which collects the vapor so you can pull the vapor through easily.


Carb Caps

These are caps that are designed to allow you to control and retain vapor so that you don’t lose expensive concentrate unwillingly. Carb caps allow you to put a hit on hold so you can take a moment to regather yourself if necessary. If nail temperature is too low then the oil might just sit there evaporating. Carb caps trap the vapor so that you can consume it when you’re ready.

Now that you get the idea of how each dab nail type works, you can experiment with the different varieties that seem best for you. Dabbing is such a new experience for many that your knowledge might go toward helping others too. The most important things to keep in mind when dabbing are to never directly touch the end of a nail after it’s been heated, never touch the oil and of course be careful when heating your nail with the torch. Beyond that, safely enjoy the weird and wonderful world of dabbing armed with knowledge!


What is Reclaim? And Why Should it Be Part of Your Dabbing Experience?


What is reclaim? It’s best to start at the beginning. Almost every consistent smoker has had a day when, for whatever reason, we simply run out of weed and can’t get anymore. On these days, the bottom of the barrel comes to light. After smoking weed from a pipe or bong for a while, resin builds up. It’s in one of these utterly desperate moments that we may decide to start scraping the resin out of the pipe or bong so that we can smoke it and have a high that doesn’t exactly taste good but still does the job. Aside from that haunting flavor, the resin from flower does the job in a crunch but, at the end of the day, it has a way lower THC content and it’s definitely not healthy. It’s mostly made up of tar which is really not the ideal thing to smoke.

Researching the Composition of Reclaim


It may not be much to look at but you still don’t want to waste the reclaim from your dabs.

With dabs though, rather than consuming flower, we are consuming oils which means that the residual material doesn’t contain tar. This brings us back to the original question: What is reclaim? As you can probably already guess, reclaim is the residual substance leftover from dabbing. Over time, you usually start to see a buildup of oily globs sitting in the water of your rig. This residual matter is known as reclaim and the oily substance can be collected over time and re-smoked. It’s a substance that has been tested for cannabinoids and studies conducted by Scott Churchill, the Director of Methodology at MCR Labs, found that reclaim did in fact contain all 5 cannabinoids that are present in marijuana and that each of these cannabinoids was active. It was especially high in CBN, which is a mild psychoactive compound found in marijuana that produces a sense of heaviness and drowsiness.

Are You Collecting Your Reclaim?

The best, highest quality reclaim oil tested by Churchill was the kind that collected in the rigs and dropdown. You can collect that oil over time and create your own batch of reclaim for those rainy days when things get desperate. Just make sure you are collecting the orange, brown residue and that you are storing it in the best possible way. A silicon puck is recommended for this. Dabbing the reclaim is so close to being as good as dabbing concentrate that not collecting it for future use is actually a major waste of a perfectly good resource.

What is Reclaim Like When Eaten?

Dabbing isn’t the only way to consume the reclaim either. You can also eat it although if you choose to consume it as food, be very moderate with the dose. Likewise you can choose to add it to hot chocolate, alcoholic cocktails, spread it on toast or add it to any other recipe so long as, once again, you consume it with great care and moderation. Start with a tiny amount. Test your product and build up slowly if necessary. You can also use the reclaim to make a pill or tincture or even use it as an oil and rub it on your skin. You can even spread a little on a pre-rolled cigarette. There are dozens of ways to consume the reclaim and of course dabbing is most definitely one of them.

The Healthiness of Ingesting Reclaim


There are a variety of ways to ingest reclaim from your extracts.

So we’ve discussed the nature of reclaim. Now we need to know what is reclaim consumption like as far as our health is concerned. Is it perfectly healthy to ingest this leftover substance? The truth is, this is really dependent on whether your dabs were of a high quality to begin with. Some concentrates are made using BHO which means they are filled with butane gas. As you can probably imagine, the leftovers from these kinds of dabs are not going to be the greatest quality. The best kind of dabs, in particular for the best quality reclaim, are the C2O kind and solventless dabs. These will give you the healthiest, purest reclaim and, of course, when you’re dabbing you want the best quality. Therefore, concentrates of this variety are a better pick anyway.

The Best Way to Collect Your Reclaim

So now that we know what reclaim is and what kind of dabs are the best kind for creating it, it’s time to discover the best way of collecting your material. The oily goo in the rig needs to get out somehow and be separated from the water and scraped off the sides of your rig. So what’s the best way to do this? There are a couple of techniques you can try but alcohol tends to offer the easiest option. The first thing to do is get a high proof alcohol, like Everclear. Regular liquors won’t be strong enough so be sure to use the high proof variety. Pour the alcohol into the rig and allow it to sit for at least 10 minutes. If you have a lot of buildup, let it sit for a longer period. Now cover all the open holes and shake the alcohol through your rig. Keep shaking until you’ve managed to get all the residue off the rig and into the alcohol. Now pour this solution into a glass dish or into a Pyrex container and cover it with aluminum foil. Allow the mixture to sit for a couple of days until the alcohol has completely evaporated and then scrape up the remains and store them in a safe container.

As you can see, there’s a goldmine being left in your rig, usable in a dozen different ways, including dabbing. Just be sure to use the highest quality solventless dabs and then collect the goods. Be aware that it won’t be the greatest flavor but it also won’t be utterly terrible. Also the quality of the high will be slightly different due to the reclaim being higher in CBN, which will most likely make you a little more sleepy. Having said that, reclaim still contains THC, the other uplifting psychoactive ingredient in marijuana as well as all the other compounds that are generally found in marijuana so it will still give you a great high. The best idea is start collecting your reclaim and explore the variety of ways you can make this orange-ish brown sticky goo work for you.


How to Safely Extract Concentrates Using the Rosin Tech


Dabbing or smoking concentrates has become a popular thing in recent years. Marijuana concentrates allow you to get a fast and powerful high by using heat to extract the terpene and cannabinoid-rich resins from a marijuana flower. The methods for extracting concentrate from flowers can often be pretty volatile. Butane gas has been used as a way of extracting concentrates until recently when newer options have changed the whole game. This is good news for the many people out there who love dabbing and enjoy the intensity of the high attained from using concentrates. You’ll often hear this method referred to as the rosin tech.

The Rosin Tech Skips the Butane Altogether


Butane systems of extraction have inherent dangers that the rosin tech avoids. 

The rosin tech (short for the rosin technique) is the name of a new process for extracting concentrates from weed as opposed to the old BHO extract methods. If done correctly, the rosin tech produces extracts almost identical in aroma and taste as those produced using BHO but offers a much safer and healthier option. As the country has become more health conscious, dispensaries have also begun stocking rosin as an alternative to BHO. The rosin tech gives you a solvent free option as a concentrate. It’s an extremely easy process to execute yourself at home and you’ll probably find that you already have everything necessary lying around the house.

How to Make Your Own Rosin

For small time use as opposed to commercial use, all you need is a hair straightener, parchment paper, an oven mitt, a knife and some weed, of course. All you need to do is:

  1. Heat up the straightener.
  2. Place the marijuana in the parchment paper.
  3. Wearing the oven mitt, press down hard on the straightener, closing it over the bud.
  4. Continue to press the straightener closed over the marijuana until you hear a sizzle or see smoke. This should take about three seconds. You can do this two or three more times, to make sure you’ve extracted all the concentrate.
  5. Once this is done you can remove the paper and open it up. You will see the rosin concentrate on the paper.
  6. Take the knife and scoop up and store the newly acquired rosin concentrate.

The rosin tech is fast and safe and gives you solventless concentrate!

The Teabag Method


The rosin tech produces terpene rich concentrates free from solvents. 

Another little trick for making the rosin tech work for you is putting the marijuana in an empty tea bag before putting it between the parchment paper. Doing this allows you to collect the rosin with ease since it passes through the teabag filter while all the residual plant material stays trapped inside the teabag. Empty teabags can be bought in all sizes so you can customize for the size you need, keeping in mind the size of your straightener or whatever rosin tech device you are using. Using heat resistant gloves may also be an easier option for you than an oven mitt, for the sake of comfort and more control when handling the rosin.

Using a Rosin Press

If you don’t want to use your hair straightener for the job and you’re willing to shell out for an actual official rosin tech press, a whole host of them have become available on the market. At this stage, they could be considered a lot pricier than just using a hair straightener but as the popularity of the rosin tech grows, the price could go down in time.

Choosing the Size of Your Press


You can find rosin presses in a variety of sizes and styles. 

The smallest rosin press looks a little like a flat waffle iron. They’re ideal for beginners who want a straightforward, foolproof way of creating high quality concentrates in the comfort of their own homes. It consists of two hot plates with a hinge. That’s about it! All you need to do is just put your pot in there and press. This is a simple device that helps you extract your concentrate with little to no drama. The convenience will cost about $300.

There are medium rosin presses available too for those who are interested in making higher quantities of rosin. These rosin tech machines usually have a 5” x 5” inch hot plate and, as an added bonus, these often have a mechanical press or a lever system that will help to really squeeze all the rosin out of your marijuana. This type of larger, more professional press can be found for approximately $500.

Commercial Level Presses

For people really looking to get serious about rosin tech, possibly even making a living out of it, the larger press is probably for you. These are a lot larger, allowing you to make much more rosin in the same time as the smaller presses. The hot plates for this larger press are usually 20” x 20” large and, on top of this, they usually have some kind of hydraulic pressure system to help you press the rosin cleanly from your buds with ease, making sure to extract every last possible drop of rosin. This kind of machine costs somewhere around $5000 and is definitely for those out there who are going to need to produce high quantities of rosin, quickly and cleanly.

Deciding if a Press is Right for You

While it is more than possible to avoid these costly machines and just use your hair straightener to produce your rosin and get a great product, rosin presses are specifically designed to give you a great product, using the right temperature and pressure necessary to get the best possible quality rosin. They ensure that terpenes are not sacrificed in the heating process, giving you a better quality rosin. That’s what you’re paying for when you dish out the cash and go that extra mile. That’s not to say you can’t produce your own home variety version of high quality stuff but it’s good to know all the options before making a choice with how to proceed.

Beyond all of this, going through all the trouble of home brewing your own concentrates just may be too much trouble and too high a commitment for you. In this circumstance, there’s always the option of going to your local dispensary and picking up the perfect rosin. Either way, the rosin tech has opened up an option of getting a solvent free, healthier, safer concentrate that is almost identical to BHO extracts and gives you the same intense high.
