jw14660 posted a topic in Hydroponic Q+AWhen growing cannabis in hydro (RDWC), does it matter if the air temperature surround the leaves/stem/buds is high (e.g. 22-35 degrees C), if the roots are bathed in chilled water (at 19-20 degrees) constantly? I am starting a hydro attic grow soon, and my attic gets quite hot. However, I have a hydro water chiller that can keep the water at a constant temperature of my liking, and I have plenty of circulation fans. I can also, regularly mist the leaves of the plant if needed. However, is there any point at all in starting an attic grow if I can only control the temperature of the water reservoir?
I've been looking in to water chillers and have come to the conclusion there to expensive! so figured I'd make my own (how hard can it be) im stuck on one thing right now, i need a plastic water block!. As i understand it when the ph is below 7 metal from the water block will get 'leached' into the water. anyone know much about that? all i can find are aluminium or copper water blocks :/ would copper be ok?
