Thanks AL, I just made 8 cuttings today, 6 blue rhino and 2 off my bagseed. I immediately put them under the light, forgetting about your 6 hr period of darkness.

I have a heat pad from a pet store that is for lizard tanks, I will be using it temporarily until I get a horticulture grade heat pad. A thermometer is on the tray to measure the heat coming off the pad. The pad is placed underneath the tray. When I get the horticulture heat pad, do I place the clones directly on the pad or underneath the tray?

Hopefully I'll be seeing roots in the next 7-14 days!
