Roger that....No, I am rather good about going with whats proven. Worst case here is to put all 48 clones in at once. Down fall of course is harvet time and the time it takes. I read here somewhere where some one had this delima and was feeding with a weak solution and leaf feeding to make up the difference but I dont beleive his plants were that far apart. These are twenty days apart. I may make some adjustments to the design and convert to 3 reservior, 3 timers and 3 pumps to solve the problem. I need info on reservior size to water 16 plants in coco, 1 gallon pots?
