What I meant by "equal" is that it does create a suction the intakes are littler than the exhaust. I water every time the soil is dry, since transplant of clones i haven't watered, its been about 5 days, ill water them today. The seeds are watered more often because they're in little cups. The temperate ranges, the absolute highest is 80 which is not often reached, right now the lights have three more hours until dark and its 74.
