In what age/day should i put the plant under the 600w hps? P.s. its hot summer and i dont have ac in the grow room.
no it wont kill a baby play but it will murder your pocket book . no need for strong lighting until there at least2.5 inches tall
Do you not have an adjustable ballast? You won't need 600watts until you have at least 3x3 canopy growing. I turn mine down to 450 for the most part of veg. 300 for the first couple weeks
I bought a digi ballast but forgot all about lowering it lol. I put mine under 600w from day 1, before they even sprouted! Just make sure its far enough away...
