Ive ran in 1 gallon pots with a 3 week veg from clone and had great success. That 50 day veg is what's going to cook his goose. Unless he runs cloth pots.
Under 600w hps. Still some mild heat issues to work out. But she's going strong at 9 1/2 weeks. Hopefully I take care of all heat issues with the switch to led.
I'm very comfortable with my 600w hps/mh. Had 2 in a 4x4 closet at one point but struggled with heat. I'm thinking two of the tsl2000 would be on the money.
I'm liking the look of the Mars hydro tsl2000. It's 300w actual. It's just under a buck a watt. I'm considering replacing my 600w hps with two of them.

Its not a company. I'm just pro granular. I use general hydroponics maxi grow/bloom. In the process of switching to N-P-K Industry's blends. Sorry for the confusion.
