Nice job on the cloner. I would also agree with these guys on the clear plastic. Dealt with that first hand. I built the same kinda thing, 20 bucks at lowes and 4 bucks for neoprene pucks. Should work great for you, just be careful when going to soil, they burn very easily. The only soil I have found that work to get root ball out of cloner is FF Light Warrior. I would never recommend Fox Farms otherwise
