top feeding frequency question

Discussion in 'Advanced Growing Techniques' started by AvacadoGeorge, Aug 31, 2008.

  1. Currently I have 2 soon to be mother plants(American Dream). They were rooted in 1in roockwool, then transplanted to 4 in rockwool. They started to grow roots out the bottom so I put them into 8inch pots with expanded clay pellets, I have them set up to a top feed system, its a steady flow, not a drip. I just got hose and drilled holes and siliconed aquarium air pump tubing to it in two locations, one for each plant. I secured them to flow next to the stem but not on it. I drilled holes in the hose near the pump until I thought the flow was just right. I am using a 130gph fountain pump from home depot in a 18 gal rez. filled with 10 gallons of water. And an air pump with a stone.

    At the moment its once lights on, once lights off, and once inbetween for 30 mins. So how often and for how long should I pump for?
