Don't worry bout it Irish, I have gone over 45 C with coco before. I am willing to bet these Dirty Irish Hempies (tm) will afford the same passive hydro reliability if not more so because of the hempy design. Speaking of which, if you do find heat is a problem, switching to coco might be the answer. The top dries out where the air roots are, while the bottom stays damp. This provides the insulation from radiant heat that made growing with 600+ actual watts of CFL possible in such a small space for me. Shouldn't be a problem for you and these LEDs though.
45 C, to save you conversion, is a whopping 113 F. I think I have seen close to 50 C once or twice. Those plants hermied mildly, but nothing serious at all. I had a reasonable yield too. Just keep a can of female hormone spray around if things get hairy and you don't want seeds I suppose. I will always keep mine on standby from now on despite the controversy in their use. A little spray early in flowering can't hurt too much.
so you fill my pain in the heat?lol. the good thing is i mixed it so the top will dry out faster then the mid to lower part of the bucket. since the bottom 2" is water it will stay nice and wet for the feeder roots, and the sunshine will get dry but still wick up some moister to keep the top with plenty of air but moist to cool them down. i am also running silicon to double my plants cell walls. i am ready for whatever this summer heat has. i tell the sun to bring it! (please dont sun, i am all talk..lol) the only two things that worry me about heat is root rot and airy buds from the heat. I do not expect my yields to be some crazy crazy weight, when dealing with temps like this and not CO2 you have to expect to lose some harvest weight. but no matter what ill still get someone saying something about the weight at the end even though the temps will be in the 100F+. but to be honest i dont care anymore. i am not here to prove these leds can flower good i already did that, i am here to show that some can still have hope when facing high temps like mine. Ive talked to many growers who just dont grow in the hotter months because they cant run A/C with their HID. all i care about if finding out if my theory is right or not. and i am pretty sure its right. IR is the heat stress causer, not high room temps to a certain degree.
