For now I have a lot of different veggies going outside, and I am trying to source a bunch of leds to do testing inside. For my first inside round I want to test Strawberries, Carrots, Tomatoes, Chili, Salads and herbs at different power per f2 and different color temperatures. I'm probably wrong, b...

Planning to do some lighting tests with veggies, so I thought I'd register here first, while I plot.

Just looking at the photo, I would have guessed that you had too much blue light... but that does not seem to be the case. Are you in a very dry climate?

How are things progressing with the tomatoes? Planning on growing moneymaker inside this autumn using strips.

Are you still around? How is your setup performing?

Oh, and for strip distance, the way I calculate it is, that the diodes have a 120 degree lens, so if your strips are 4cm from each other their beams intersect about 1cm below the lamp. If your diodes are 12cm apart, their beams intersect at around 3.5cm. Even at 16cm their beams intersect around 5cm...

I would imagine your main question would be if you make one large lamp, or multiple smaller ones?
You would probably do well by making 3 lights from the two foot strips, covering 50x56cm so if you run multiple strains you can set lamp height independently.
