I am currently using water farms for my moms they work great but I have them all seperate since they all need different amount of nutes so it is kinda of a bitch to change out 6 individual res's but if they were on the controller like what you want to do it would work great. I just had to start some new moms yesterday after having them for 3 years they have gotten out of control I had 3 that were 8 feet tall I had to use a ladder to take clones so now I have new moms same strains of course and am going to try to do some bonzai's
