Haha, flower button! Good one. That toy must be great for growing cannabis. The button turns on the red diodes. and possibly turns off the blue ones. Smart.
I've had different light setups and by far the coolest is full spectrum LED grow light. I was able to burn plants with white LEDs, the plants became somewhat chlorotic (especially tobacco seedlings - they turned yellow). Drosera seedlings could not turn red, as they did outside and even more so under full spectrum leds.

I'm planning to make a larger grow light setup. I intend to overwinter a couple of chillies this winter. Should be fun.
