Lighting source - pt. 4 DIY refelctor hood #2

This is a downsized reflector hood for the 10w 6500K CFL lamp I originally purchased for the tomatoes.  Since the LED array has failed due to being underpowered I am using the 10w CFL for lettuce.  The reason for this is it is going to take 2-4 weeks to have new PCBs made.  So in the meantime I can test the nutrient formula.  Here is the CAD drawing for the hood which is made from sheet aluminum pop riveted together.

A new rockwool cube with the same lettuce was started a few days ago and will be in the system in a couple days.
