I wanted the more intense T5 fixture so I could have a taller space for blooming out the slippers and other stuff with tall spikes. HID lights can also suck for blooming stuff like phals, the flower arrangement comes out awful. I guess putting two HID lights on one of the circular light movers might correct that problem, I have one on a linear track and it helps a little but they still come out better under fluorescents. -danny I'm not sure if your are getting all good information from the Guy at the hydoponics shop. I've looked up the T-5 lamps specifications and I only see about a 10% gain in light over a standard 40 watt. However being small as they are you may be able to cram a lot of lamps close together and get a higher amount of light.You could also do that with T- 8 lamps which are a lot less costly.

They are about 20 inches long and 13 inches wide... 3 of them will fit in a 4 foot long run - replacing 3-2 tube shop light fixtures - so 600 watts in place of 240 watts... |

Apparently these are high output T5 fixtures. The bulbs that came with my
fixture say they are 54W / 4200 lumens each, 216 watts for the four tube fixture. That lumen output doesn't sound all that great for the amount of power but it's ok I guess. They claim to be some sort of grow bulb so the lumens/watt may not be the highest possible? I just did a quick search and found another 54W grow bulb that claimed to be 5000 initial / 4700 mean lumens. The eight tube fixtures are 432 Watts, so their output should be comparable to my 400W metal halide fixtures but spread more evenly.. -danny "Dusty" wrote in message . 17.102...

I am glad my winter is still three months off, this thread shows that
finding the right lighting at a reasonable cost is difficult. Right now I am leaning to a HPS kit (www.ezhydrokit.com/default.php?cPath=21) since I will need the heat in my garage anyway. When you make your choice please post it here as I would like to have the info. Joe T Baytown danny wrote: Apparently these are high output T5 fixtures.

Your situation is different from mine. My growing space is in a
sunroom. It has a nice, leaky steam radiator for heat during the winter. I have east, lots of south, and west exposures--so I don't need the "sodium" aspect of HID lighting. Also, because I use my growing space as an office, the last thing that I'd want is HPS lighting--it is weird and ugly. MH light is far more attractive, and balanced with natural daylight, it provides a complete spectrum of light. The banks of fluorescent lights under shelves are not obnoxious. Because you are growing in a garage, you might want to check out the dual MH / HPS lights--they give a balance of growing/fruiting light. And in a garage, you might want the extra heat. I don't know where you live, but if your nights are cold (mine are sub-zero), you might want to invest in some heated seedling mats. My floor-growing areas in the sunroom are chilly because they are above an unheated garage. Putting in heated seedling mats under the orchids' humidity trays made a huge difference in their health. Also, a min/max thermometer is a good investment. At 2 AM, it can get damn cold, and you'd never know it unless you are an insomniac. jtill wrote: I am glad my winter is still three months off, this thread shows that finding the right lighting at a reasonable cost is difficult.

Orchid care is always, like politics, local ;-)) Average high here is
92 and average low 44. We always have a few nights around 32 and a rare swing into the 20s. Joe T Baytown OrchidKitty wrote: Your situation is different from mine. My growing space is in a sunroom.

One of the other tricks that he was telling me about was putting diode lights, like the plastic rope lights, in the plants, you can put them very close and wrap a plants that need more light in them because they produce little heat. Plus the put light to the underside of the leaf. This is interesting because a friend of mine who has marble windowsills in a cold room uses the rope lights under the plants to keep their feet warm. Hmmm... Reka |

LED's are basically worthless if you're trying to generate heat. They are designed to be "cold light". I'd bet your friend has small "rope lights" on incandescent bulbs, not LED's. Do you know of a link to show me the difference, Ray? Thx, Reka |

This is sort of off the thread, but because my sunroom growing area is
above an unheated garage, my floor is cold, especially when the temperatures are below freezing. It has been my experience that orchids in S/H really don't like having cold feet. So last winter I bought the largest-available heated seedling mat and put it under the humidity trays of the Phals and Catts. So I had fluorescent light above and the heated mat below. Boy, the plants grew like crazy--especially those in S/H. The heated seedling mats don't put out that much heat, but it's enough. wrote: Reka wrote: Ray wrote: LED's are basically worthless if you're trying to generate heat.
