I am about to start flowering and I was wondering how far a 400 watt HPS bulb be away from the tops of the plants? Should I be at full str nutes right off the back? Please let me know
start at 1/4 strength with the nutes and for the light about 18in should be around right but just use your hand and if the heat is not uncomftable for u then the plants should be good.......ras
