First time cloning. I just took multiple cuttings and dipped them in rooting gel and placed them in Rockwool Cubes in a nursery tray with a humidity dome, and finally misted them. I’m using a 70w full spectrum LED. It doesn’t emit that much heat so I have it pretty close to the top of the dome, like a couple inches, Is that too close? I’m not sure how the power of LEDs compares to other lights.
