Hey burdo im starting to assemble my growspace, and after a lot of reading, viewing and research on the web, i came across with even more questions about the lights...some ppl say that enviros are to slow (no prob with that), some say say that the best is MH for grow then HPS for flowering,,,,bla bla bla....what i want to ask u is:

How many enviros do u use for grow and flower stages?
Considering that my space is a 4x4x4 box with mylar all around will 2x125w enviro be enough (one for each stage)?
How many plants can u get under the 125´s for a good light/plant ratio?

Tks 4 ur help dude, and hope ur crops be high high
