I ask because the most efficient method to grow trees is with bare vertical lighting. A bulb in each corner and one in the middle with 4 plants arrainged like a diamond around the center bulb. Unless your room is very narrow, growing 2 plants will waste light.
john, you do realize this thread is over 3 years old right? he just explained it, arranged plants in a diamond pattern and put bulbs on the outside of the diaomd so the plants have lighting 360degrees
doubt if KC is around anymore, but i have a couple pics.
that Mofo is in a 3 gal dwc bucket with H and G nutes.
