Light distance

Hey I just put my clones in 5 gallon pots a couple night ago. Is the distance from the tops of my plants ideal?

Place your hand at the top of the plant canopy. If you hand is hot move light up 2" at a time until you have a gentle warmth on the back of your hand. If your hand is cool and not warm at all, lower the lamp 2" at a time until you get the desired temp. at the plants
