this is my first grow
2x2 grow tent with mars hydro600 LED, what height should i have my light away from the plants. im germinating now, I cant find an exact number, just a range, so I'm assuming about 20 in. from top of plants.
also i purchased a 2x4 tent since the 2x2 is REALLY small, I plan on planting 4 plants so I guess ill do one in the 2x2 and 3 in the 2x4 with mars hydro TSL2000 300watt.
also my humidity is around 35 but I don't have anything in the tent right now so i'm assuming when I put plants in there and start watering the humidity will go up in the tent?
I'm running 4 different strains, white widow, power plant, jack herer and gelato. wish me luck.
