PM on leaves only, are the buds safe to smoke? Hydrogen Peroxide bath good?

Fellow growers,

this is my 2nd thread regarding my PM issue. The first one was about finding solutions to this problem. Thanks for the suggestions!

Now I'm about to harvest in 2 weeks and i'm wondering:

Are the buds safe to smoke?

I'm asking this, because from researching about PM, a lot of people are saying it's really bad for the lungs so that it should be thrown away.

But it's not clear to me if that only applies if it's a real bad infestation.

The plants are in week 7 of flowering now.
The PM first appeared during week 2 of flowering. Over the time I treated it with a sulfur spray, 2 x fungicide spray, hydrogen peroxide spray (regularly), 2 x milk/water spray and 2 x garlic/water spray.

2 plants are more affected than the other 4. Few stems were affected, and also a couple sugar leaves near the buds. But with hydrogen peroxide I can blast the PM right off those spots and it won't come back. Right now, I can't see any PM right away.

So again, how safe is it to smoke buds of a PM infected plant?

And, has anyone tried Jorge Cervante's hydrogen peroxide after harvesting? My main concern about this procedure is how it affects the quality of the buds, after soaking them in HP?

I also attached a pic of PM near a bud (encircled) below.

Thanks again!!!!

Greenops, people generally say it's bad to smoke PM, but I'm also fairly sure there isn't any scientific proof for that. This is really unfortunate that you've been battling this since that early in flower. PM greatly affects final quality imo because it stunts growth along the way. It's also my understanding that once you see it on the surface of the plant, it has already completely overtaken the plant from within. Just like when they say you see 1 cockroach, there's 1000 more inside the wall you don't see and the 1 you see is the least of the problems.

I've smoked moldy buds plenty of times and to be honest it's always in our environments.

I wouldn't recommend smoking if you are immune compromised.

That said most people have smoked a tonne of it and probably never knew it. I haven't seen any evidence it's detrimental. The spores are in the air in your grow room and in the air all around you all the time.

Definitely lowers quality/yield.

Thanks for the input guys.

So it seems there's no proof whether a lil PM can cause harm to the immune system, it's like try at your own risk...

I sacrificed so much time to pull this through, not sure what to do.

Anyway, what do u guys think about Jorge Cervante's PM wash tutorial????
Will it make the buds safer to smoke? How will the PM bath affect the quality?

PM, unlike mold is generally deemed non-hazardous to humans. But a bath of 1 oz/gal of 35% FOOD GRADE H2O2 will kill it and is safe. Just dip in bucket of it right after trimming then hang to dry. You can dip after dried but you'll darken the bud a bit.

Thanks medicalmj. Where did u find info on it? I've been googling this for a while...

Have u tried the HP bath? I will def do it if it wont affect the quality of the final product.

I originally heard about the H2O2 bath from Jorge Cervantes, don't ask what book or vid. A while back I had PM and it was really bad on a couple plants so I did this to not only ensure no PM was on smoked but to keep it from coming back. I didn't want to go open a jar and have spores fill the room. I ended up doing some after the buds were almost dry. I did turn the bud darker tho. The taste and smell didn't change. PM will affect the taste on its own as you may know.

the peroxide bath didn't seem to alter the finished herb. it also didn't remove the pm, you could still see it with a scope after it dried. i don't think it will hurt you, you barely have it from those pics.

I've done it, it worked somewhat. I think the actual physical spraying after the fact is what removes most of it. The H2O2 should definitely kill it.

The quality didn't seem affected. The dry took a bit longer as the buds end up drenched, but that's not a bad thing. I agree it doesn't really remove the PM.

On my plant that was just covered in white fuzz the soak took almost all the fuzz off. But I put the buds in a bucket of H2O2 (tepid as not to break trichs) and really gave them a washing. Probably most noticeable improvemnet on really covered plants. It did darken the buds and perhaps leached some chlorophyll as well.

I dunked my buds to rid them of PM and it ruined them. The color of the buds and the smell were unattractive. I would not reccomend this to anyone and tell them its better to let them dry and cure. I ruined half a LB!

That flies in the face of most folks experience. If you do it, you should be certain you can control your temperature and RH and keep a fan blowing on them until they are dry enough to simply hang.

Keep air exchanged. Etc.

Back in the days when PM would attack a certain strain of mine (no other strain--just that one) and I found myself weeks from harvest, what worked for me was--

1. Aggressive attack with potassium bicarbornate (Greencure) spray followed days later with,
2. Applications of Serenade (normal amounts) mixed with Raw Milk (start at 50% then reduce to 25%...yes that is 500-250ml of milk for each liter of spray liquid). Start at 50% and gradually reduce to 25% and spray every other day...or every third day at the very minimum until harvest day. Don't be stingy, soak the buds!
3. Day of harvest, whack the plant then smartly walk to your shower and give the whole plant a nice shower (think autumn mist--not fire hose pressure). This will wash away all spray residue, then hang her up in a dry spot under an oscillating fan and within a few hours all will be dry and you can do your normal dry/cure thing.

Yes, the buds will show slight burn but the Raw Milk spray aids in the recovery (and if you run a week longer or so--most buds will show signs of recovery and be more marketable)....but the buds will not be brown and awful looking.

I have tried soaking buds in hydrogen-peroxide, sodium bicarbonate, and potassium bicarbonate--and was blessed with miserable results...and the worst smoke I ever had. pitui!

Raw Milk is preferred, but if unavailable, whole milk (homogenized) will do. BTW, the baby poo smell of Serenade is reduced by half when you add Raw Milk in the 25-50% range.

This study found milk to be effective in against zucchini powdery mildew...http://www.agrar.de/agenda/bettiol.htm

Good luck...you have lots of good information to select from.
Cheers!
 
Hey dude, I did the h202 bath back in January when I got my first case of PM.

Anyways, to answer your question: Jorge Cervantes h202 bath works AMAZINGLY!!!

When harvesting clip off a branch, do a close-trim on each of the buds, and then submerge it in the h202 and water mixture for 5+ minutes. I waved it back-and-forth in the bath gently, like Jorge did, for at least 30sec each, and then let it soak for the rest of the time. While its soaking start trimming a 2nd branch.

When the next branch was trimmed I would remove the 1st one from the bath, gently shake it to remove any dripping water and then place it on a clothesline to dry, and then place the 2nd one in the water, doing this continuously for every branch.

While they dried, I kept the fans directly on them for the first day to make sure they didn't rot.

I harvest over a LB and it was some of the best smoke I've ever had. I didn't get sick and I didn't die for PM exposure, lol. Don't believe the hype. Also, my friends said the Gods Gift I grew knocked them on their asses. It didn't kill them either.
The h202 bath DOES NOT KILL POTENCY, very much, if at all. Trust me.
 
Don't soak your buds in straight h202. you need to dilute it like Jorge Cervantes said. If I remember correctly it was like 1/2cup of 3& h202 for every 5 gallons of water.

If your buds changed color after this you are not doing it right.
