How does everyone battle powdery mildew and mold issues in their cabinets? My humidity is above 90 and I can’t seem to get rid of these two!! I have tried hydrogen peroxide treatments, and grow safe. Nothing works!! Help!

Do you have a fan in your cabinet? It could be an airflow issue

#### Plantgirly replied on 2025-02-02

Yes I do! It’s a pretty strong fan at the bottom and blows up I also have it slightly cracked to allow fresh air to seep in

#### Plantgirly replied on 2025-02-02

By strong, I mean enough to definitely circulate through the entire tent without beating the crap out of my plants

#### Kades replied on 2025-02-02

How big is your setup? I have two fans in my tall Milsbo, one at the top and bottom to make sure the plants at the top are getting flow as well.

That would be my only idea but there are some great peeps on here with more knowledge on the higher humidity plants. My only really needy plants are the ferns and begonia.

You'd need to kill off all the mold, wipe the cabinet, plants, and pots down so there's no spores, and treat each plant with a fungicide, like growsafe, sns, arber, etc. Every 3 days for at least 3 x

Otherwise you get it to go away and it just emerges again.

Springtails eat mold. They seem to be the go-to choice for terrariums, so they'd be worth a try
