well... according to what i've researched... keeping the fan on low is good enough for just a few little plants...
just a nice calm rustling of the leaves is sufficient in addition to proper exhaust...
i'm nto quite sure if a fan can burn the leaves.... but all i know is as long as the leaves are just twinkling in the wind... the plants like it...
i just discovered one of my problems.... i tested the runoff water, the excess water that comes out after watering my rockwool, and it is WAY too alkaline...
do you test your water that leaks out of your pots... ?
if not you should do that kuz i'm starting to see my plants perk up just from adjusting the input water so that the ouput water isnt so alkaline (aka putting more acidic water into the plant)
i think the only time we should put full strength nutes is about a week or two before harvest...
other than that i think the most we should be nuting the plants is maybe 3/4 strength at most
but i will continue looking for the answers
also, im going to be watering my plants once a day with ph'd water
