The supplemental side lighting will of course increase horizontal growth from the plants.

With the CFL's suspended 2'' from the canopy until they are at around 5-8 nodes would be plenty. But the side lighting will trigger the side nodes. It's like LST, without moving the plant, just aiming the light. And if you used those tubes with 2500k's in them for flowering, it really should improve the popcorn nugs down low.

but Opie should have a hella good explanation. I'm no expert.

Good luck and Be Safe:jointsmile:
