PM spores are contaminating every square inch of the grow building. Touch a bud and spores are underneath your fingernails. Spores are embedding into shoe laces, growing in dust bunnies and on the bread.

i have washed with peroxide/water with some success , but i recommend trashing anything with pm, its a tough pill to swallow, letting the humidity go up and down is a easy way to grow some PM, keep VPD proper and room clean you can pretty much almost eliminate PM, good luck

Peroxide bath is after you harvest. Before you dry. I’ve had to do it a few times. I finally got my shit under control. I went back to running my MH in winter.

That is a bad time for PM. Remove all infected leaves (spray with water first to reduce spread of spores while cutting off leaves) and get them out of the grow space.

Bleach the tent or room. Get a filter, be it furnace, panty hose, whatever you can find to filter the incoming air. Increase airflow into the grow and the plants. Spray plants with high pH water daily until harvest. Make sure plenty of air circulation and spray water as lights come on.

Remove any leaves that show spots before they get worse and just treat with water until harvest.

Why is PM bad in January? I got PM in January for the first time ever in 8 years.
