Material list
Topled Light® LED Plant Grow Strip Light with Power Adapter. $22 (red and blue leds)
aqueon suction tube (Had off an old water change hose... just using the clear plastic tube)
PVC fittings and 1” pipe (sorry don’t know what they are all called. Worst case if someone really wanted to know I could find out.)
The blue piece off the drain pipe to fit a little fan on...
Basically from the pic above. There is a little fan on the right hand side of the pipe. It flows air down and into the tube and across the leds at the bottom. I drilled air holes to allow the air to flow across the leds and then up the pipe on the left. Also the pipe on the left acts as a passage for the led power supply. Pretty simple idea I just capped off each end of the clear plastic tube and ran a 1” pipe from end to end inside. Then wrapped the 1” pipe with my leds. Honestly this is a really bad diy build thread as I didn’t take any pics of the build. Sorry.
