Just wanted to through something in on the CFL bulbs. Check out 1000bulbs.com, they have a really good line of CFL. They say 2 to 200 watt but I only saw up to 105 watt. They have 100 watt (supposed to be 500 watt incandesent equivalent) for about $21.00and $9.50 shipping. Shipping for more than 1 bulb is still $9.50, at least up to 4 bulbs if I remember right. I haven't gotten any yet but as soon as money allows I want to get some to try them out. I was thinking of doing a box for my mother using 10 bulbs. Two in each corner and two above but maybe smaller than 100 watts each. I'll make my own reflectors and mount them on some type of scissor set-up (that i'll make also)so that I can adjust them horizontally according to the size of the plant. I don't know, Looks good on paper. If anyone has trouble finding the site for the bulbs let me know and I will try to help. Have a great day. P.S. To whom it may concern, 1000bulbs.com might be a company that would be interested in advertising. Just a thought.
