I couldn't find any dolemite lime to lower the PH so I'm going to use the low tech method Klondike suggested. I'm hesitant to drop it below 6.4 so I will probably drop it to exactly 6.4 and watch it from there.

I also went ahead and swapped out my flouro's.. I was usin t12 lights which I've found out suck really bad. I've replaced them with CFL's and will contemplate swaping out for high output t5's in the future.

For now I have 8 23 watt 1500 Lumen Bright White bulbs and 2 30 watt 2000 Lumen Bright Whites.

Total Lumens is 16000 over a 15" x 15" area. I still need to isolate it better now that I'm using a smaller space.

Here are some pictures; How much better is this setup over the 4 40watt T12's I had going?

It defintely burns my eyes out (it's much brighter than the picture suggests. I turned down the apeture and shutter speed of the camera all the way to be able to take the pic). I have to go in there with sunglasses on now. If I had a reflector or something it wouldn't hurt my eyes so much.

Anyone have any good ideas on how I can make a reflector for this? I already got creative with how to actually hang and mount the lights. Now need ideas for a reflector.

And anything else I can use aside from Lemon or dolemite lime to lower the PH in the soil?
