First run with a Sea of Green.. Advice on latest plans?

New to the forum, I appreciate the time for anyone overviewing my start-up for this first inital go at the SOG method. I am working with a closet space set up, and have a few more days until my seeds get in. I have 35 comin my way (10 Big Bud, 10 Bubblegum, 10 Northern Lights, and 5 Silver haze) all for the most part indica, which from my understanding grows well in the SOG. I have got three 175w MH i plan on using for veg, and about 650 watts of HPS for flower. Haven't decided on a watering method, but did pick up one Mini-Jet aquarium water pump (106gph, 120V, 5W). Not too sure if its effcient for watering 15-20 plants though. Another thing not decided, to plant in seperate containers or to put multiple in the 12' diameter buckets i have already bought. Advice?

The beauty of sea of green is you don't really need to veg. I use 1-13w to keep the little ones alive after cloning but you don't need to use 3-175W mhs.

Just so you know sea of green means lots of small plants as opposed to a few big ones, you end up with a canopy that gives you more even light distribution so you lose less light.

never put more than one plant per container, never.

Good luck. In my opinion, SOG works best when using all the same strain... they compete a little more evenly.
