try going with coco, 20gal pot, in veg considering you have one 1000w and 400w light available you can veg12 plants or more, they should veg until at least 30in. Flower 2 plants- 1 plant per 1000w guaranteed to get at least a pound per light if you feed according to the nutrient feeding...
i would say blue dream and strawberry cough. i have a hell of a blue dream that yields great! 1.5-2lbs per 1000w and the cough has always been one of my favorites.
