this is what i just did.(see pics) i put a taller one that had less vegetation..(ie big leaves)in the center right under the light ,then the five tallest ones got spaced out even from each other one foot from the center plant.,then the five shortest ones went onto five gallon buckets evenly spaced 18 inches from the center plant but between the ones sitting on the floor..to me this looks like every plant is now as close to the light as i can get unless anyone has a better way? please let me know.
