Gelato - Hydro First Grow

All showed signs of flowering a few days ago. Had to put #4 back with her sisters due to a pump failure. Now have all four Gelatos running off a $11 fountain pump from Harbor Freight. Good flow, had to turn pump down. For a $11, I'll put a couple of these on the shelf for back ups. Changed all feed lines to 3/8 line dropping down to 1/4 at flow tip. Had to turn pump down onto min to get a good flow that would not backup the system. Flushed system using Sledge Hammer and changed from Fox Farm to GH for nutrients. Mostly due to cost point... we'll see. My son and I are growing together, sharing jobs: I do the hydro setup - he does LST and lights and such. He does Fox Farm with his strains and aim more towards GH.
