I have recently modified my closed loop hydrocarbon extractor expanding the sample stacks and collector, so that I can use very poor sample quality and still hit the monetary sweet spot. The truth is that when you keep your solvent liquid by maintaining -60C and pushing it through the sample...

Exactly what is where. Interesting read here: https://pubs.acs.org/doi/pdf/10.1021/acsomega.7b00996

I have tried to eliminate as much of the waxes, lipids, carboxylic acids and esters in the extraction process by using lighter hydrocarbon solvents, cryogenically treated sample matrix and filtration under high pressure thru 2 micron sintered metal. The stuff is so refined that I do not...

My experience making BHO from aged trim is that due to decarboxylation the color will be very dark, which is extra work with the color remediation. Refining the color involves mixing with ethanol and filtering through a Buchner filter, again and again, many, many hours of waiting then boiling...

After having a conversation/show and tell with a buddy that recently had spent CAD 500 on six 4 oz. bottles of CBD tincture @ 2% with eyedropper lids and thought; DAMN! If I could use CBD @ 20%+pot and get equivalent yields compared to THC @ 20%+ pot, then somehow emulsify that into a...

I got my first shot of Pfizer 5 days ago and have another six days before it's protection kicks in. I already have a great deal less anxiety. IMHO anyone talking about not getting vaccinated just does not know or understand the possible consequences of being infected.

I thought that "Go fuck your hat!!"was just a silly saying FFS

Okay 100 gm sample, @ 8ml/gm = 800 ml of solvent or 8/10ths of a liter, weighs 480 gm ( 600 x 8 = 4800/10 ) When you invest in the extra plumbing and paraphernalia going to closed-loop anything under 500gm per blast wouldn't be cost efficient at all. When I start a run I prep a minimum 1500gm...

Closed-loop means that you have a sending/recovery cylinder. Weigh your sample matrix, calculate volume at 8ml/gm then weigh the proper amount of solvent at 600 gm per liter into your sending/recovery cylinder. VIOLA!

I figure the ballpark is 8ml/gm I use 4000ml ( 2.4kg ) for 500gm of sample with butane. I find the weight of the solvent is more important than the volume. When mixing solvents or preparing for a run the predetermined amounts weighed into a separate cylinder, then when recovered continuously...

IMHO the difference will be a darker yield due to decarboxylation usually a more red color tone to it. I had acquired a half skid-load 2 years ago of trim that had been accumulating at a grow for the best part of a year and it took me about 2 weeks to run it all and those batches that were used...

I made a batch of gummies recently with 12 grams of my dewaxed, 2 micron filtered BHO @ 60% THC poured into 48 by 5.5 ml cannabis leaf figurine molds. At 150 mg each two of these tasty treats is a good buzz, one is just not enough, three is a trip and four only if you are in a great deal of...

It was a home built closed loop system which was quick wash. I have not yet succeeded in blowing myself up but I am still trying

Some Ethanol + Sulfuric Acid add a distill column and you got Ether.

QWISO is very nice. Forty years ago I kicked that up a notch by substituting DME for IA

The method which experts agree upon producing the finest extract is Butane. Like anything best results require due diligence. PPPPPP Proper Planning Prevents Piss Poor Performance..

CP (Chemically Pure) 99% 120lb/24Imp.gal. bottle $900CAD approx. Air Liquide or Praxair

Okay, what will happen when the butane far heavier than air under the influence of gravity will be pulled downward toward your heat source (even outside) and when the concentration of fumes is great enough the butane will ignite (flash point -60C) WOOOOOOOF!!!!!! You are on fire now! Forced air...

70g Ass kicker

Prompted by TheSwede's submission of yielding 30g from 300g, I decided to run some complete schwag to see what kind of yield would result. I used an old column (non dewax), smallest one that I have and packed it tightly with 480g of dried powdered sample that you just could not catch a buzz by...
