Would you recommend 150 watt HPS lamps for anything?
And also, can you grow with tons of 70 watt HPS lamps and just pretend they're really good CFLs? I can get 70 watt HPS ballasts for only like $20 apiece.
we would definatley need more info regarding how big of a space you are using and how many plants you plan on growing, this is just not enough info to go off of.
i imagine you could..... but it'd be better and more efficient i think to go with one bigger one, less wires, less plugs, just easier. I'd say a 400W. thats what I use.
