3 out of 12 of our clones developed mildew last 2 days they are 7 days old from clone and the only thing different in last 2 days is i left the 2.5x2.5 homebox closed when lights and fan goes off. so now that i know what i did wrong poor ventilation.... clip on fan is not enough air moving around in there with 65% humidity so now what should i do baking soda? and water right now and sprey them>?
