How do you know what size net pots you need? Is 3 inch plenty? I dont really see why you would need a large size. Also I have been running my setup on while the lights are on and off when the lights are off. I plan on getting another timer goin in there to maybe give it one or two waterings during the night time after switching to 12/12. Also what about root growth and rot? Will the roots from one strangle another? The roots are getting really frickin long! As long as they have the nutes they want they should be fine with the roots right? And then my final question. Root rot from heat... I can keep the water temp at around 84. I haven't had any rot problems yet, (been running for a couple weeks). Do you guys think I will have a problem as long as I do my reg water changes?
