Hey all! :smokin:

I changed my lighting system a little bit today. I took out the original 90 cm. fl tube I had installed on the side and replaced it with three 60 cm. tubes at 6100K (daylight). The tubes mounted to the hanging board are 5600K (as far as I remember---cool white). So, I now have a total of 8 fl's lights in there generating 13, 965 lumens. That's just a little over 2,000 lumens per square foot for my growing area.

I also fixed the side intake and exhaust to be as lightproof as I could get them while still retaining maxium air circulation inside the box.

As you can also see, I lightproofed the gaps in the box using black aquarium filter cut into strips and wedged into the openings.

This box is about as lightproof as it will ever get.
