MORE buds!

[quiltergal]

Does your fixture have a reflector? Mine doesn't. I just bought the bare bones ballast and tubes, daisy chained them together and called it good. Could be the heat is building up inside the hood of the fixture and has no way to escape. Since my bulbs aren't enclosed any heat rises up and around them. Here's a pic of my set up. Taken last spring. The shelves are now packed! I'm also using the 6400K, 54W bulbs. I have burned a leaf or two, but only when they were actually touching a bulb.
