@GYOweed,
yes i know but i don't have a lot of choice .. because i was in led i thought it was a 600w but in reality 100w and for not that its overheating in my aunt in the early morning when my lamp light up, I open my window at night. what are the consequences if the night is much colder? Thank you
@HusslerBabyLTD,
yes if it exceeds 10 degrees, I have 1 plant which is in difficulty because of the earth "all mixed" because it is too nutritious while I put only 2ml / L of "Bio Grow" the other plants I mixed several compost and everything is fine
