1) I do a 2nd quick wash. The soak time is the time it takes for the last Buchner funnel (from first soak) full of solution finishes. Then I then filter that thru at the end. - If under vacuum in chamber, you should need no more than 40C inside. 2) As @sdd420 said, I only decarb if edibles. No...

So this is what I do. This produces a clean, smooth, and flavorful concentrate. Contrary to the majority, I soak for 24hrs minimum. If everything is completely frozen (solvent, flower, vessel) prior to adding solvent to flower, there is not much to worry about as far as chlorophyll goes. You...

Not sure what you mean. My dabs are some of the smoothest and tastiest you will find.

So this is my latest batch. Sub zero extraction with isopropyl. I dont call it QWISO because I dont do quick washes. 56g organic MAC 1 soaked 24 hrs in 2400ml isopropyl at -23C. One wash. Recovered yield was 9.8g. Inside rotovap purging. Then off to the vacuum oven to finish. Finished...

I cant comment on using acetone as I have never used it before and no desire to do so in future. Ethanol and iso are my chosen methods of extraction. I will comment on the use of carbon though. "don't ruin your product." To the contrary. The use of carbon is going to enhance it. Not sure what...

I use both iso and ethanol for extracting. If using quality solvent, ISO or Ethanol, there should not be any residual if purged properly. Furthermore and in my experience, ISO offers a far more 'offensive' odor than ethanol. But as I said, if purged properly, there will be little to no traces...

Yes, I have filtered thru a carbon cake above the DE. The DE I am using is Celite 545. But best results were from adding carbon directly to the solution, stirring, and filtering thru DE. Much simpler to just add it to the solution. I do 2 filter passes with DE. The first pass is the initial...

I cant edit the above post. I made a mistake. In my above post, I stated I use approx. 1.5L solvent/ounce flower. That is incorrect. That was based on a 2oz bud batch. So typically about 750ml/oz. This might seem excess and a waste. But I want to have the potential to capture as much goodness...

Using carbon is definitely a thing to do if you want a cleaner and tastier product. Carbon will not only remove chlorophyll, but also remove odors and and other nasties that can give a concentrate a foul taste. It should be a step in everyone's refinement process. It is very simple to due and...

If purged properly, there is little to no residual solvent. Ethanol/iso extraction can offer a very tasty concentrate if care taken in extraction and processing. In my experience, yields from QWET or QWISO are similar to BHO friends get. I typically get about a 17% (by wt) return. QWISO...

When doing sub-zero extraction, I do only one wash/soak and set that aside. I will then do a second wash at room temp and pull whatever is left. The second wash is saved and used elsewhere. If only doing one wash, then ensure there is enough solvent to capture all available important...

Agreed. This is the cheapest and easiest. Filter the shit out of it and you will have a happy concentrate to dab. CCell vape carts are cheap and work very well with thick oil. But if using vape carts, you will want to filter well. Particulate in the oil will foul the coil. The trick to...

How do I watch your video? It says it is private.

I have found that ethanol extraction will retain flavorful terps if evaporation done at low temps. I have done sub-zero QW batches and batches with several combined washes at room temp. Evaporation always done in a rotovap under vacuum. Sub-zero extraction typically yielded lower in quantity...

Yes

Gods Prime Glue. Ethanol extraction.

Hello everyone. I am in mid 50s and my entire working career has been pretty much in the oil and gas drilling industry. I have been smoking weed since my early teens. I have found for myself, it is a much better alternative to pharmaceuticals. My past main hobbie was high-end PC building and...
