I Have Mold!!!

Aeryn · Nov 19, 2019

I've recently discovered that I have mold forming on my hydro plant! I learned that some plants dont like high humidity, and that's why I have mold. I need help in trying to kill it! I dont want to loose my plant.

The newer growth up top doesn't seem to have mold like the lower branches do.

Does anyone have any tricks of the trade?
I've already added another fan and brought the humidity down to below 30%. She seems to like it better as the degree of the mold has gone down and I'm.not loosing foliage anymore, but it won't fully go away.

PM is a bitch once you have it. Personally I'd use wettable powdered sulphur and really spray them down, then follow up with sulphur burns.

Once it is in the plant you can really only manage it and treat it, you cant cure it in one generation without using something toxic. It just keeps coming back a few days after treating. When I had it I did the sulphur wash, then 1.5 hrs burns every day for several days, then once every 5 days for 1.5 hrs.

In flower I would do 30 min burns once every 5 days or so and that seemed to keep it under control, last burn was 2 weeks before harvest.

There are other spray on products like greencure people swear by. But sulphur is my weapon of choice in the battle against PM.

Learning from this post.

If he was to get rid of the plant, have a brand new plant in there, could the new plant get the mold, because his past plants have had mold? Like, do spores stick around in the tent? or, powdery mildew rather. i guess its mold lol.

Absolutely it could, but not so much because of spores spread by the plant, they will die in a few days without a host. But it came into the grow from somewhere, so the source needs to be addressed. Maybe sealing up a little tighter and using a quality hepa filter or close to it on the air intake. And if PM is something that crops up in your garden periodically, the plants should be treated with something preventatively like regalia or sulphur vapor so the mold spores dont infect the plants to begin with. Exposure to spores is hard to avoid in ventilated grows in some regions. All you can do is make the plant an inhospitable host.

I'd say kill it now and bleach the entire tent inside and out and the surrounding area around your tent, same as your filters, fans intake exhaust osculating fans take the covers off if you have them and bleach everything then let it all dry out before trying again. Attack it or it will take over and continually ruin your crops. imho

Thank you everyone for your helpful tips. I will wait to kill it until.i have no other option, but I really dont want to. I've put a lot of time, energy, and love into this plant and I dpnt want all that time to go to waste. Another thing...it seems to only be attacking one strain. The others are showing now signs...

Yup. PM starts on the stems and moves to the leaves. Once you see it on the leaves you have spores everywhere. Bleach, H202, Physan 20, Chlorine Dixoide ect. to kill it but honestly if you arent fumigating you won't get all of them and have to be hella vigilant. Stylet Oil (JMS) is a better alt to Neem for PM as far as horticulture oils goes if you want to go that route. Wettable sulfur like Microsulf is the best bet and burners.

The problem is tho this can kill everything you put into it for a long time coming. Running multi rooms and prepetual in a basement it took me a full year to get rid of it 100% and to not have to treat for it. Head that warning. Make sure to run HEPA on any type of fresh air intake and also buying a pair of shoes for just the grow wherever its located (room or location) and leaving them there and do not bring outside clothes in is a really good practice. I have a couple sets of clothes/shoes that never leave my grow for this reason. Also the reason I went fresh air to sealed. You see PM (or something similar) pop up on the outside plants in my neighborhood.

Maybe one of these bitches inside the tent?

Green cure. Or baking soda and water solution with a wetting agent.

increase air flow, reduce humidity at night.
PM loves hot and dry days with cool and very humid nights.

You know what they say, an ounce of prevention is worth a pound of cured bud.

In my opinion air circulation>low humidity in terms of power to prevent mold. I see you have added a fan which I'm sure will help, my rule of thumb is that if there is enough airflow to make all the leaves move around mold is unlikely to be an issue at any reasonable humidity.

Aeryn · Nov 20, 2019

Thank you everyone for you tips and help! I went out and bought some Plant Therapy Mold and Mite Solution that I was promised would help. I will hopefully be buying additional fans to suspend from above to help keep the air circulating. I will keep yall updated on how it goes! Fingers crossed!!!
