Jondamon had some really good info in his post
I'll do 16 - 1 gallon mesh bottom pots per 4X4 tray under a 1000w. Vegged to about 10" before flip. Run to waste, fed via basket drip stakes. 3-4 feed cycles per light cycle. Each drip (not really drip) cycle is long enough to achieve runoff. Fucking rocks. But lots of plants, if you have lots of lights

I'll do anywhere from 4-9 plants(with 6 being what I usually do these days)in 5 to 7 gallon pots, per 4X4 under a 1000w. I treat these ALMOST as I would with dirt. The main difference, besides the slightly different nutrient needs(what jondamon said, and what I said in that other post), is NOT to let it dry out as much as you would with dirt. In peak flower, I water every other day. It rocks also, but much more veg needed of course

I use Big City Hydro mix lately, just to save on labor

You still want to rinse your coco, i don't care what brand. I transplant, then I rinse with water + 1/2 tsp calmag, ph'd to 6.0. I rinse till runoff is clear, and ppm is the same as what went in. Then feed, and walk away.
