I built my cloner per stink buds instructions but made my lower legs 6" long because I used the 14 gallon rubbermaid tote. Made 35- 3/4" holes in the top and like i said used sheet rubber insulation for holders. Just threaded the roots thru the bottom of the net pot then added hydroton, worked great and no shock to plants. Also included current picture of veg-back right plant is at 16" today it was 8.5" in last picture.
I have not grown these strains before am just getting back into growing after a couple of years off. Was growing ak47 and would flower at 16" and yield about 24 oz. Will be taking clones tomorrow and then will be going to 12/12 in next couple of days. BTW am growing jack flash, white widow, and diesel this time around.
PS the black cloth around the bottom of the cloner is landscape fabric with a electric tie around the top to keep the pump covered. I had plenty laying around and I couldn't see spending 10 bucks for a pump cover. Works good
