I'm looking at either 600w or 1000w mh and hps combo.
OR if I can do it right, an LED setup.
Oh also, I will have recirculating buckets with the fill bucket being out of the grow space. 10000000%
DE, or better yet, cmh. Cmh emits UV, which can activate up to 15 different plant defense mechanism and protiens - Oil production, resin product, stomatal density, increased aroma, photosynthesis efficiency, strengthens plant, etc. just to name a few. Best par spectrum that closest match actual sunlight, compared to all available lights in the market (that i know of so far). Only uses 315 watts (per bulb). When dialed in, you'd be surprise how much buds only 315 watts can produce.
1 315w cmh provides even canopy lighting for 12 of my 2.5 footer in a 6x8 veg room. 2 weeks ago, they were only 10" tall.
