My DIY rig with 2 14W 2' T5 FL, using packaging foam for my computer. Able to put 6 seedboxes inside, each box can be segmented into 2, so 12 compartments. Original concept using D.Adalae to capture any insects that lurks around the lights. Until I kill most of the D.Adalae...

That's another story for another day.
Setup for second experiment: 3x2 variants
