Making BHO with PM ridden buds?

[OvergrowDaWorld]

Im 1 wk from harvest. The temps dipped into the low 60's and 1 strain got Powdery Mildew really good.
I havested 14 plants that had it, and am gonna make BHO/Shatter with them.
The process will purge any PM completely out of the crystals to make it 100% clean and safe to smoke yes?

Each plant will give me about 3/4 of an ouce to 1 ounce apiece of dry flowers with PM all over them.
How much Shatter should I get out of 10 ounces... Approx?

Any special things that should be done to be successfull?

Ive read that the process doesn't rid the end product of the pm it only concentrates it. Not sure though. Careful bud.

You`d probably be better making water hash from frozen bud as this is supposed to kill then wash any contaminants off .
I believe C8 is right in BHO process possibly concentrating not eliminating .

 

[OvergrowDaWorld]

Well I guess I truly need emergency help then.
So dry the buds. Freeze the dry buds. Then make bubble hash?

U need to hit up gray wolf in the consetrates section. The pm will come thru the Bho process with ou the use of a syringe filter. He mentions the size required and possible sources.

the solvent is sure to kill any mold/spores more readily than water. I don't think anyone really knows if any of the possible toxins that some mold species form would be extracted. If it was me, I would try and wash off as much as possible with water, let it dry out, and butane or other solvent extract. If really worried then only use it in edibles, but I personally wouldn't be afraid to vape or smoke it.

PM doesn't produce known aflatoxins, so we remove the mold filaments and spores using a 0.2 micron syringe filter, and it turns out fine. That is also fine enough to take out any bacteria.

I usually syringe filter it, immediately after filtering out the waxes from winterization.

Or just give him time to post up

It wont wash off. The PM wasnt on any fan leaves really. Maybe a spot here, a spot there.
Mainly, it stayed on the sugar leaf, and then spread to the calyx's near the base of the sugar leaf stem.
I tried to clean them by rinsing the growing flowers in a Hydrogen Peroxide and water solution, then rinsing them with clear water, and it didnt do anything. The PM didnt come off any of the flowers at all. The areas were still bright white. Like I said, its almost 99% on just the crystals on the sugar leaf. Theres no getting it off.

No need to dry buds just freeze . It saves time as all you are going to do is place any buds back into wet water . Freezing also stops any further deterioration of bud .
I am only going on my own experience with bad/rough bud that was not fit to dry & smoke because of pm bud rot etc .

Nevermind.

How do you identify powdery mildew? Does it happen quickly, or progresses slowly?

Thanks

Splotches of white powder on the leaves. It is systemic and can move fast once it gets started.

Usually a sign of insufficient air movement and high humidity.

Yes sir! Remove the fan leaves that impede airflow around the buds. I have found that if you water before the soil drys out too much helps as well.

 

[OvergrowDaWorld]

Thats exactly what happened.
Poor intake. High humidity. Low temps. Bam! PM!
All fixed. The concentrate came out wicked good.
There wasnt alot of pm so it was easy to strain with a .02 syringe filter.
Worked perfectly. Great shatter! It went fast!

Do you have to use ethonal or can you cryo butane (de wax)
with that filter?

toss the shit in the trash,

thats where ALL PM AFFECTED PLANT MATTER GOES, IN THE TRASH

 

[Sirdabsalot46n2]

I have to agree with TJO^...

Particularly if this is going to be utilized as medicine.

I too know the pain of losing an entire plant or 3 in my friends first grow, because we/he didn't take proper precaution for mites..

Shit goes on the trash.
4-5 months of time, energy, nutes, electricity and love...

In the damn trash, as I'm not only medical myself, but my patients are most all medicinal users also.
I reckon if this for recreational purposes, go for it...


But...
Blast, use a minimum of 10 coffee filters..winterize , then the solution must be filtered using a .2 micron wheel syringe.

Important.. If you just think you have correctly identified the mold/PM..
Double and triple check...

PM and Botrytis are the only two that I am aware of that do not produce an aflatoxin.
Whatever your decision may be..
Good Luck .. And I'm sorry that you are dealing with this.

 

[JointOperation]

i hope more people are as mature as the last few.. toss this in the trash.. in the end KARMA will return the favor.. if you sell this to people.. more then likely. karma will deal you a shitty hand.. but good luck with the extraction.. we all know how hard it is to lose a harvest.. but wat goes around comes around. and its not always fun to be on the shitty end of the stick.

You can always pre-rinse with food grade H2O2 to oxidize any spores and then you'll be fine. Mix about 1/2 oz per gal of 35% soak/agitate then let dry.

Note DO NOT use any of the hydro store H202 as it contains harmful additives.

And PM isn't toxic to humans. Personally I'm more concerned with the solvents.
