Not the most thrilling subject. Do not see a lot of threads floating around about the bottom of the bottom leaves.
Autistic, the stereotype for being perfectionist, I will not say anal retentive, anyhow, my lights are dialed in pretty well. It took 5 grows of paying serious attention, but the forum being a cross section of humanity I am sure I have company in here.
I will skip the cooked stems, wilted leaves, shorted CFL's and all the things I learned that did not work.
The LED T8 replacement tubes I use in my SAD (seasonal affective disorder) room gave me an eureka moment. They are 140 degree 22 watt 5000K LED's 4' long. Bright, squinty to look at them lights. 110v either end lights them up.
I grow trays, row of 4, row of 3, row of 4. 11 plants. The canopy is 3' x 4' and the LED's fit right down the rows and just one socket with 110v slips onto the end of each.
Enough light is emitted to make the innermost leaves glow from transmitted light. And the glow is yellowish, the blue is getting sucked out by chlorophyll. No bleaching in 5 days, heat is spread over the entire 4', no hot spots either.
As noted, I am not the only perfectionist, other members, anguished (those leaves are not getting consistanly equal light), are possibly trying underlights in DIY (not much out there) mode. The rate of improvement from top and sidelight manipulation having reached the point of tiny returns for the effort, leaving underlights as the next area for visible gain.
What has been done underneath that has not caused damage?
Any discrete colors been tried?
See, I'm not after much. But at the cost of LED light, I really really really do not wish to duplicate layouts proven not to help (violet light) or even cause active damage (T1 CFL's) when each light costs multiple hundreds of dollars.
Time is not of the essence, the white LED's under the indica will keep me occupied.
