Thanks, I appreciate all the input you've given. It looks like I'm going with almost exactly what you're suggesting.I think you got some killer ideas I just don't wanna see you spend more than you have to. I am of opinion that you should do 9 cobs running at 75ish watts each. Put the outside cobs 8" from the 4x4 edge and space the rest 16" on center. That would have each cob covering 8" in every direction. Saves a lot of money and I believe accomplishes what you want done. If you want you can drive them harder but I think that's in the ballpark.
Vero 29 SE Gen 7 3000k running @ 38.7v x 2.1a (81.27w).
So 1647.018PPF vs >2,000PPF (Solis Tek 1000w DE HPS) initial output...With 28% degradation after 3 months as a member on another forum tested that puts the HPS at 1440PPF in 3 months. I'd be surprised if the HPS bulb really reaches those numbers in initial out put anyways to be honest. But I think I've finally got a cost-effective match or maybe even superior fixture to HPS with the Vero 29 SE Gen 7 3000k running @ 38.7v x 2.1a (81.27w).
Total cost of the fixture would be around $776.60.
Are you saying 60 gal of substrate per 1000w light? And don't you need to have 20% less load than your driver's max? Ho do you run 240w on a 240w driver?You need about 60 gal of substrate to hit high g/W numbers, even so, you can fit 4 plants to a 1000W.
Personally, I am running 80W COBs in groups of 3 to fit on a 240W driver.
