I cut a few clones on the 1st, now its the 14 so in two weeks all I've noticed is the stem has changed texture a little bit to a pale and has little bumps. I cut at a 45, then cut again underwater to ensure no air buble went in the stem. Then directly out the water I dipped them into rooting powder. I have them in jiffy pellets, originally I had them in a container with 1in of water so the bottom of the stem was still submerged. I was told not to have them sit in water like that, so I cut a drainage hole in it. I have a heating pad under it, temp 75-80. I mist three times a day. Every 5 days I pulled a few out to see whats happening then I rediped them in the powder. Any ideas why they've not started to root?
