well question to the Hydro gurus well am gona be attempting a DWC but it will be out side, al of course cover the container with black polythene and duck tape to stop any light, to stop algae and heat but i have a blacked out container out in the green house and even tho i think the Ghouse is well vented its always a few degrees hotter than the outside, and that means a hot DWC res. i haven't had any issues with bacteria but since al be growing Mj this time i really don't wanna fuck up. are there any ways to keep the solution cool or does it not matter, what temps (hot) are really bad for roots ?
