i got 2 70w hps floodlight theyre watered about twice a day coz its really hot so the water evaporares pretty quickly but theyre really healthy and i doubt theyre stretchin for light coz their stems r already quite fat for 8 day old seedlings and a cutting btw this is my second crop and theyre much healthier and faster growing than the others so i must be doing things better and i jst use normal tap water for now till they get bigger then i start to use 5-5-5 seaweed fert so its all good atm i got the lights about 1.5-2 inches above the plants i thought it was really close but the plants arent burning so its ok i guess thanks j.g.g. i will keep postin as i go ahead btw i no 4 plants under a 70w is pretty dumb but its SoG so its all good
