You'll benefit from some Cree LED replacement "lightbulbs" from Home Depot (<<link) to fill in during flower. Two RW75s give you 19w/sq ft. You'll want a little more I think. 22.5. Maybe 25.

It comes down to total yield expectations more than anything....and looking at g/w is how you get to that yield. Think 1g/w as a good grow expectation. Some get more, but some get less too, so just start there for planning. I don't like or support g/sqft really. It's miss leading and what seems like a great grow could be measly and not even close to max production per soft. More space cost to get the same that could be down in a smaller foot print will cost more than running more(actually the correct) wattage. Real estate is expensive, specially compared to power...even a Hawaiian's power bill.
2 75w's are NOT enough to compare to what you are trying to. The 150's are meant for a 2x2(ish)...so 2 150's in a 2x4 tent is what you need to keep up with 400-600hps. Maybe even more to keep up with the best 600hps growers...defiantly not less imo.

I would say 3 RW-75's would get the job done pretty well and 2 RW-150's would max out the space.

Are you doing a scrog with the limited height? You will need 12" to 16 " between the rw-75 and the plant and more for the rw-150.
Which takes me back to what I said: add 7-8 Cree lightbulbs for $100.
More coverage and flexibility in a shorter tent. We're just talking about my 22.5w to 25w, your 28w or GG's apparent max 37.5w.I agree with GG's "cost of space" factor. 15g from 15w/sq ft would be 1g/w, but not efficient for the space used.
But, it seems like vertical space plays a role too. In a shorter tent, 37.5 sounds awfully strong.
Frank/Rosenthal (Growers Guide) said regarding T5 that 40w/sq ft was the optimum, and approaching 50w/sq ft was diminishing returns. (Not that you wouldn't get more, just that the cost of electricity versus cost of space wasn't as optimal.). I would expect efficient LED to be appreciably lower than that.
I wish there was a way to quantify these things for LED in a cu. ft. manner, quantifying where diminishing returns occur. Something other than equivalency to HID which many don't have experience with (and still masks HID watts per cu ft).

Id be more than a little maddddd.....I know they moved and all but I need it for flowering lol .

LEDs with lenses can bleach a plant if too close,it's not so much a temp thing.

The reason you light isn't there is your fault. Needing a light asap because your mid run and freaking out isn't a companies fault. Specially if warned of the possibility by said company before you ever clicked buy. Just saying...responsibility

Oh youre totally correct . I'm just wishing I had it sooner greengenes . I said I Was an idiot Already . I wish I just ordered somewheres else and it's my fault for not doing my due diligence of reading the everything . I understand their in the middle of a transition and getting everything squared away . It's my fault and im mad at myself . Yes the shipping sucks for my situation and it's my fault for not recognizing that. I would have gone with advanced but hindsight is 20/20
u will appreciate the fact that you went a51 once it arrives man, trust.
they are great bang for your buck

I am going to do a tray by tray I think...
2 trays size 4x2
2 area 51 2015 lights vs 2 300w advanced
It will be a beautiful event if I can make it happen.

Most def, I have no preference I just want the best I can get for a reasonable price. They can duke it out in true old school fashion, although I don't think I will be able to partition them so there might be like very minimal crossover on the bottoms. I will have to see how I can arrange it.
