Well the 150W I was planning to use to help the 430W .... I wasn't planning on getting a new or larger lamp at this time. I just freaked when I read that the 150 burns almost as must watts as the 430 and wonder if it would be worth putting up the 150.

The size of the area the plants are in is 2'x4' so the 150 should give me a foot ... and the 430 gives me 3 feet so that would give me enough light. When I have the funds I may consider getting a 600W I would imagine that would be more energy effiecient than the two I have now.

I plan to put up mylar (gift wrap) to help with the light as well. I'm just wondering is it going to be worth the extra cost to run.
