lol, i dont know why they would say put the rocks in the buckets. thats beyond me... anyway, i go with the recommended feeding program depending on what strain im growing. when im growing mandala, i dilute a bit because they have some super genetics behind them. you have to use the lid to put the pots in, and to keep the light from the roots... i thought you wanted to use only the lid with no net, i didnt know how that would work, but if you found a way.. more power to you lol
