Its a real pain in the balls to constantly checking each bucket especially when its full of roots.
He's absolutely right. GH now makes one called the "Power Grower" that has something like 8 5 gallon buckets and a big controller and if I'm not mistaked IS a recirculating system to prevent the exact issue hydrohut is talking about.

The w/fs need some modifications to grow big plants.....I've drilled extra holes in all my little red buckets and....in fact....have recently DUMPED The little red buckets altogether due to drainage and rootbound issues.
