Hey I'm guessing its nearly impossible at three weeks into flowering to separate these tangled roots to transplant them into a bigger dwc resivour? I'm having trouble keeping my temps down under a 1000w HPS light.. My plants are about 80f and my water temps get up to around 84 sometimes.. Any suggestions on how to keep res temps down? Right now I drop PH adjusted ice cubes in there but it doesn't even really drop the temps..any suggestions? I have 3 fems in there that are begging for lower res temps!
