you've been a busy man Eddie I've been doing this for about 6 years & have used 250,400,600&1000 w hps now I have a led I have yet to top the grows I did with that light I didn't like the vacuum cleaner noise of the vortex type fans so I ran one of those "y" type 6" splitters & ran 2 of those Home Depot duct fans which are incredibly quiet I ran a 3x3 tub & 10 gal reservoir fed e&f from the bottom coco in 2 gal smart pots I ran 9 plants ,sometimes 6 but that was a real good setup I've only recently strayed away from that setup the 600 is not as costly to run as the 1000 & once dialed in is a good balance of performance & economics for awhile I ran a 1000 in one room & a 600 in the other but it cost to run i was seriously thinking about a 250-400-600 switchable ballast as you could dial in your light output to the plants needs increasing as they developed I also have a 1000 dimmable setup & a 250-400 switchable that performs very well & if I get a tent might be used until I can get another led for now it's my backup
