Not positive on BJBs, but I know for certain Ideal ChipLok, Vero Poke in, and most connectors are 18-22awg ready. Hopefully that 16awg will fit into the holders connectors.

Nope Air! It's a 3x3. Here's my thinking. I wanted to build a light for a bigger tent but also be able to use it for my 3x3 right now. The 9 COBs will mean each sqft technically has its own light which is complete overkill I know. I have a potentiometer for each row so I don't even need to turn on a row or 2. Also, and let me know if I'm wrong, I'm hoping running these lights barely on will keep cost down although I'm not really that worried. I hated that my crappy burple LED light didn't provide even PAR across the whole tent and now I hope I get it.

What I really need help on is to determine what the output is without a PAR meter. I have marked the pots at 25, 50 and 75% based off of my meter. I would really appreciate the collective minds here helping me. I have 3 Strawberry Cough germinating. 2 will be in the tent in 7 gallon fabric pots and 1 will be outside in a 20 gallon fabric pot.
