    I just made a mix of 1 oz peroxide to 1 quart of water in a spray bottle and soaked the plants.. when should i do it again? and how often and for how long?

    once i kill the mildew is it better to use neem or milk to keep preventive of it coming back?

    not sure if u should put peroxide directly on plant, dehumidifier will help in stopping it spreading.

    Yeah thats a general gardening website bro. Only if absolutely neccessary spray shit on dope plants (h202, milk etc),as it usually makes mold prob worse due to adding moisture.A much better bet would be to make sure they're in low humidity envirinment, osc fans, dehumidifier to lesson the chance of this happening in the future.

    what i couldnt figure out was how i got it in the first place

    room is 75 lowest-82 max
    humidity 20-30% max has neer been over 30
    i did have my window cracked a bit so fresh air can enter and its been in the 10-20f outside with snow and ice
    my tent is 4x7 with a 440cfm exhasut fan, a 8 inch intake fan and a 16 inch oscialting fan..all mylar tent..my resavoir is on the outside of the tent so no moisture from that is in tent
