How does it compare spectrum wise to a 400watt HPS?
and is it worth going the extra mile for these opposed to convention grow lights (HPS/MH/t5)
:joint::shock:
So I'm building my ebb and flow and was wondering what the TDS and/or EC levels should ideally be in the reservoir for a good grow.
Anyone have links for an 'ideal' hydro grow something like checklists
