see what you can do with what you got small grow for you to grab smoke from those lights will be alright but you will be out by the end of the week..lol
i was looking at em today at lowes and they have 3 hps light ballasters one horizontal that says 70w but the 100w and the 150w bulb fits in it.
and two vertical ones that wher 100w and a 150w witch one should i get?
get 100 watt for a 100 watt ballaster not something less to fire up more watts..i dont know much about those but htg supply got a 150 hps for 69.99 for plant growing not a security light
