My res is just an 8 gallon Rubbermaid type thing with holes cut in the lid to fit the net pots.

No HID, though I'd love to have a nice 250W'er HPS. I just can't afford it right now. I'm using CFLs at the moment. I have 126w total and 84 of those watts are 2700K while 42w are 6400K. I'm considering replacing my three 42w bulbs with 3 100 - 124w ones. If I can find some that I can afford. Replace at least one of them anyway.

I'm also gathering what I need to build an E&B system.
