On my last grow I used a neoprene collar that had a large center hole in the middle. I'm pretty sure it was too big actually as I got some mold down below the neoprene. I see that this is nothing new as many people use a neoprene collar that is tighter. Black Stars seem to be the best solution. My question is this; are the plants able to push the neoprene out of the way as it grows bigger then the hole? Is this why the Black Stars have slits in the center to allow for expansion? I want to make sure and use the right collar this time to prevent mold but I don't want to put a tiny cutting in a hole the right size only to find that it cant push the neoprene away from the middle to allow for trunk growth. Make sense? I would really like to use the same collar from cloning to flowering in a 3" netpot. What's my solution?
