I used power strips and lightbull socket adapters. Can fit 3 bulbs per power stip. The adapters are like a 1-1.50$ then i ducttape those to stuff between the plants so its like a vertical grow. I leave the difusers on. Or else it wouldnt work the way i do it. The plants are maybe 8 or so inches at most to only a couple inches at the least right now, but ive had them almost touch the bulbs or touch for a day or so till i moved them. The leds are so directional that theu didnt work well for me without the diffusers in the way i wanted to use them but they rock the way i have it set up. Absolutely stompped my floro fixture.
