wen to put hps on

[bud boy]

You can carry a full term grow using an HPS.

I beleive in florous/MH for veg. and HPS for flower. but there is a lot of difference of opinion on that statement.

Use the HPS with a floro if you want. The blue spectrum helps some. Don't give small plants dirent HPS light unless it's 400watt or less.
