i see what ur saying...well if later u wanna turn the rubbermaid tubs the other direction then u should probably go with cfls just bcuz of the versatility...essentially you can have cfls any which-way you'd like vs tubes u can only put horizontal or vertical depending on the lighting and reflection ur going for..
Why Use CFL's?
Because. Not everyone has a big space to grow in. When space and heat are an issue, HID's become less practical as you are faced with either rigging a cooling system which could involve cutting holes in walls, ducting, and more power usage, and of course more $$$. Or what if you're just growing a couple plants at a time to keep your own stash full (like me), and don't want to go through the trouble of HID lights? CFL's are everywhere, in all shapes and sizes, and are CHEAP. Most need no special fixture, and can be placed much closer. They are a great way to start out growing, keep a small crop going, or use with HID lights. With practice, your CFL grows can rival your neighbor's HID grows.
Using CFL's:
One of the advantages of CFL's is that they screw into any normal light socket. Therefore, mounting options are endless. Take into account the size, shape, and heat given off by CFL's when deciding how to place them.
-Light comes from every square inch of the bulb, and to get the most out of them, try to have every inch facing as much plant matter as possible. More light comes off the side of the long 42w spirals than the front, for example. CFL's are not as intense as HID lights, so distance is critical. You don't want your lights more than 4 inches away from your plants. With LST, you can put your CFL's literally inside the plant, between branches so that all the light is being used. Try to light all sides, not just the tops.
-Reflecting light is important with CFL's to use every bit of light they give off. Use good reflectors, paint your walls flat bright white, or get mylar.
-However, if your CFL is too close it may burn the leaves, so trimming or a fan may be needed (recommended anyway for stronger stems). Bigger bulbs obviously are hotter than smaller bulbs. Fluorescent tubes can touch the plant without burning it, but an average CFL will roast anything it comes in contact with. Even 26w CFL's burn. You want to get close, but not too close. Try to stay about 1 inch away. Having a fan blow right through the plant over all the lights helps get them closer. And monitor your plants so they don't grow into the lights. If you're going away for a week, move the lights up in anticipation of your plants' vertical growth.
