Well, there is a hybrid approach that I came to have, by being the Rube Goldberg of DWC in a hall bathroom. But, I had a bathtub, so I could have an RO water barrel plumbed into the shower head, etc. But, it was only 9 x 5 on the floor with the cabinet taken out. Toilet took the RO waste side drain.
I had 2 x 10 gal totes, small so I could pull them out for cleaning
- pumps in each, 550 gph is good, on timers, to feed emitters on each bucket
- table, 3 x 4ft above those, leave good room for the totes
- dutch trays with drains connected to the totes
- 4 plants in 2.5 gal rose buckets
So, it is all a matter of what will you do. If you have 5 ft wide 6ft tall, pruned out, pair of Veg monsters, you might want to put 2000 w over them.
I had 4 x 4ft tall at most. 1000 w works fine.
