I see (I think) the problem you're describing with one rez being un-able to mantain equal levels in all buckets...

Why don't you...

Hook-up a water pump to your rez... then, divide that feed line into X number of hoses... You put one of those hoses per growing bucket...

When the water pump moves the water, it will throw a mix-effect into the overall bucket/rez system.

What do you think? hydro? Zandor?

I think that it might not work, due to the fact that maybe the nutes don't move throughout the system... I don't know... let us know...
