Hey im pretty new to growing and i just wanted to clear something upp.
whats the difference between metal halide lights and hps. I mean
i know the basic gist of a hydroponics system its just the lighting part i need help with
MH are primarily in the blue spectrum that encourages veg growth. HPS are a full spectrum like the sun and used for flower. I use a combination in my flower room with 20% being MH.
