I am using a 48 bucket Ebb & Grow with 8x1000. In about 10 of the buckets I have 2 plants that I started in the room each at about 10-11" tall sitting in 3" grodan. I'm experienced with the Ebb & Grow, but this is the first time I've put more than one plant in a bucket. It's been about 3 weeks and so far I'm not having any issues, they appear to be growing at a normal clip. I would advise using a large reservoir. Hope this helps.
