a little late this season but was wondering if any of you knew about strains that can deal with indoor temps of 83-88 degrees better than a regular strain. side note, what strains is everybody growing anyways. ive got the hog and heavy duty fruity.
switch your nutes to General hydroponics and use the lucas formula. no reason to bother with organics, watch this weeks penn and teller on organics. use the H2O2.
the idea for the cooltubes are air comes from an outside source through the cooltube and out of the grow area. the air pulled from the room would not be as cool and you would be putting unscrubbed air into the attic.
