this is my first grow. running 2 x 1000w HPS, hydro 4x4 trays, hydroton and rockwool, FloraNova nutes, just trying to get my water to be RO and my lights ventilated. I have a nice cool grow room downstairs with no light coming in but it heats up with one or both lights on. gonna grow 8 plants in each tray. the clones we have are a bit stunted due to waterlogging in the rockwool, hence the switch to hydroton. also getting all the toys such as ppm and pH meters, RO system and fans/ducting... just farming for yield and fun.
