Hello fellow growers!!! I've been thinking about purchasing a 600 w hps digital ballast and a good spectrum bulb. I really don't want the cheap offer that the hydro stores are trying to sell me. Would just like some more info On what brand bulb to get? I want a bulb that gonna supply a nice spectrum for my plant. If any of u have the answers please holler. Im gonna be throwing in 2 led triband grow lights for some extra spectrum. Also what's the difference in cost between a 400w and 600w?
