The Big Grow

Almost exactly a month ago I was starting my 4th grow, decided to go big this time. Ended up with a pretty nice room too. Well hidden, locked down, inconspicuous, vented, full mylar in room, 1000w hps (we're flowering now), 18 fem so far after 23 started, 4 different strains. 6 papaya left, 3 NLxBB, 5 White Rhino, and 4 of the mountain high seeds ( they are turning kinda purple). My question is, would it be worth running a 400w mh light in addition to the 1000w hps? I havn't really read about anyone running both for flowering and havn't had the oppurtunity to do it before. Has anyone done this and what were the results?

 

i've seen great results with mixed spectrum grows; tho they are usually a 2:1 ratio and not 1:1. Also they are usually done with like 3 400/600W instead of 1000W and 400W.
