Those ones with 2 weeks to go should be good, the couple of days ones are not too shabby either man. Should give you something to smoke at least.
What extraction method? Got tons of dry sift want to try something different. Plus Iām running a 120micron screen so i could do fluid extraction on what is left in it
Sorry for the late reply, but my extraction method of choice is the classic QWISO method but instead of isopropyl I use methanol, which gives way better yields at the expense of some terp loss and a bit of extra wax/chlorophyll in the end product. And cheap, can buy a big bottle of Methyl Hydrate at any hardware store for cheap, and if you have a lot of material itās way more cost effective than other solvents like buthane or isopropyl.
Does it evaporate any better than iso? Might make some oil this weekend
Thanks for replying at all lol anything special about purging that youāve learned?
Methanol will air purge just fine usually can leave it overnight at room temp or a little warmer and it will evaporate fully.
Iām impatient though so I usually just purge it off in a pyrex pie plate on top of a skillet turned down to its lowest setting lol
Another upside is itās a bit less volatile than ISO, āsaferā if you will, as in it doesnt fill a room with noxious gasses. Its odorless for the most part so you should still use proper ventilation when doing solvent extractions, but its stoic properties are much less dangerous than ISO or buthane.
But dont take my word for it, heres a study that explains why itās a better solvent:
Theres other info out there too. My only personal tip would be to use short 30 second soaks if you want a higher quality product. If youāre okay with a lower quality but higher return than aim for closer to 1 minute (but not any longer). Can do a second wash too but I find the first one gets most of what we are after. Everything else is the same as QWISO including straining, winterizing, re-winterizing the info is out there.
The soak time is basically all thatās separating this product from RSO, which uses longer soak times (sometimes even overnight) to pull out more of the waxes/chlorophyll/whole plant material.
Also regarding yields assuming there is high quality input youāll expect to see returns as high as 30% but I tend to get about 18-22% back on high quality frosty trim. Bud gets me a bit higher.
Is winterizing when it goes into a vac chamber? (Iāll look it up in a bit). Iāve got a vac chamber for wood stabilizing I could use if itās a benefit
Winterizing in this case just means freezing the product, doing the extraction, then putting the solution back into the freezer prior to purging. Helps separate the good stuff from the waxes/undesirable contaminants.
Itās not necessary but it will definitely give you a higher quality product in the end.
Been almost 2 weeks since my last update so I guess Iāll let everyone know whatās been going on.
I chopped a few of the plants in the Mars tent, they all grew to be just single cola plants with more than 10g each. Still a few left that are finishing. Very disappointing grow but is what it is.
Temps are still low and RH is still high. Been trying to find some exhaust set points for my TH16 the last few days but things have gotten overall colder and more humid (18C/75%RH in the Bridgelux grow, 18C/55%RH in the Mars grow) and thatās not making diagnosing my issues any easier as itās just more non-ideal variables in the mix.
But the one smoking gun Iāve found was about a week ago when I decided to run some tests on my runoff and found it to be very high EC so I did a complete recycle with full strength nutrients (900ppm MaxiBloom/100ppm calimagic) at around 5.7-5.8pH and overnight the plants improved 100%. Been doing that every few days since.
I did this again today and they are looking great in comparison to where they were. This pic doesnt really do it justice but heres where Iām at today.
I am glad they are improving for you Trev, My plants have been so high in nitrogen this last 8 weeks, I dont know if your plants need more N, or its just the light, and what leaves should look like normally lol.
The light/white balance definitely makes them look yellow and they kinda are but its exaggerated in this pic. They hadnāt been fed in 4 or 5 days and had used up a lot of what was left in the coco. I expect them to be improved tomorrow if my assumptions are correct.
50-100 autos!! Do it up, bro! Outdoor is always such a gamble. I see it like roulette - place bet on black, ball lands on redā¦double up, bet on black, lands on redā¦double up, bet on black, ball lands on BLACK!!!
Are these in 1 gallons?
This is what you use to do your shatter? How do you strain fast enough to not go past the 30-60 second mark? I did a qwiso and used a regular strainer, cheesecloth then coffee filter and it still took me about 40 mins to do 1/4 lbs of materialā¦
I was looking at paint strainers at an auto body shopā¦hmmmm
Yeah 1 gallon and in coco/perlite. Iāve had success with these in the past have even grown QP plants in them no problem. I wanna get back to that point lol.
As said Iām sloppy and dont mind a bit of extra junk in the end product so I just squeeze it out and thatās it but when Iām going for quality Iāll just strain it through a stainless steel strainer or cheesecloth first as it drains quicker. Youāll have some flakes of material come through the screen but just strain them through a coffee filter and then back into freezer overnight.
Just depends on how picky you are lol
And then use a double boiler to evaporate the methyl hydrate?
What brand do you use? Stupid questionā¦but does is there any kind of āmedical gradeā or super high quality stuff?..or itās all the same?..just thinking about additives and impurities
The stuff I use is always labeled as 99.8% Methanol. Iāve used a few brands theyāre all the same. I donāt use a double boiler just pour into a pyrex pie plate then onto a warm skillet thingy on a low setting. It will also evaporate at room temp if you leave it for a day or two.
Out of likesā¦
I found this onlineā¦says 99.9%

Thatās the stuff. Wayyyy cheaper than Iso and more pure.
