I'm too cheap to buy a real clone machine so i built one. I first did a 6 clone one to see if it worked,and yes it did work very well. So i was in Home Depot and they have 64L tubs on sale $4.00 each,and the top i wanted. I drilled 15-3" holes and painted it all flat black. It has 2-5" air stones also. It's full already,almost,3 Aurora Indica Clones are going in today. One AI has Female preflowers,so i'm taking 3 clones. The 6 Bubble cloner i'm going to use for starting seeds.Fem seeds that is.
