Is bottom heat necessary for fresh cut clones?

[Noonin NorCal]

Hi friends i posted this question in the "growing cannabis questions" I forgot to mention that these clones will be going in a greenhouse for light dep. Is bottom heat really needed for rooting clones? Im not sure on temps when lights are off at 18 hours probably around 60 degrees. Im just in a pickle i have a heat pad but its way to big for the # of cuts I'm trying to root.... Thanks

Not necessary, but they'll definitely do better with even heat as opposed to a cooler root zone.

I try to keep temps between 78-80 in the dome. Good luck

shoot to root ratio,s apply in all cases.
I found 60 f /15 c leaf temp and 77 f / 25 c root zone temps optimum for rooting.A
