    they dont ship with bulbs unless you request them... IMHO i would look for a 5000k, 85 cri bulb...

    if you look at the hard data and spectral curves, the highest PUR/PAR values typically come in at 5000k/85CRI... dont go for any higher CRI, it is just wasted energy in the wrong wavelengths

    that is what I use anyways... now as for manufacturer I would prob try and find phillips or sylvania... the phillips are nice,

    personally... I came across a sweet deal on a whole case of german made 5000k/85CRI

    I use T8s in the walmart fixtures. I grow in a 10x10x8 chamber in my basement using 14 fixtures total. I'd love to go to some more high powered lighting, but I think I have all of the heat my highlanders can handle. I get temps in the low to mid 80s in there during the day. I also use the big metal shelves from lowes. For the larger plants, I have an area with hanging baskets and the ceiling above them is covered in fixtures. On the shelves, I keep the lights about 2" above the tops of the plants.

    I use air conditioning to get my temps down at night. They drop to about 70F without the AC and to about 60F with the AC. I played around with tons of different ideas to cool the chamber without losing humidity. Some methods worked pretty good, but the temps usually remained at 65F. I ended up deciding to simply pump AC air directly to the chamber. I run four different humidifiers to keep the humidity up at night.

    I've yet to have a problem with the light fixtures and moisture, although every now and again a single light won't come on in the morning (not sure if that's related). Unplugging the light and plugging it back in makes it come back on. I've been running these particular fixtures in a high humidity environment for about a year. Has anyone run them longer and experienced any problems? I put the light fixtures near the walls of the grow chamber so the power cords can be run through a hole in the side of the chamber to be plugged in outside of the chamber.

    Thanks Ryan ans Sara. That is good info too. Have you thought about using a freezer to help lower the temps in your chamber? I am planning on a chamber on top of a small freezer. It will pull air in from the chamber into the freezer and then back into the chamber. You need to do routine defrosts on the freezer, but it is supposed to keep the temps down in the chamber. I will plan to insulate the chamber as well as i can with foam and the lights will be segragated from the chamber itself by a piece of glass so I can duct away the heat with little of it affecting the chamber itself. For that fixture I will definately be using T-5 lights because it will be a little further from the plants than the GR. The chamber will be astheticaly pleaseing to the eye by design. I hope to keep my villosa alive long enough to get it to the chamber if not I will buy another and then have a Hamata and other ultra's in the chamber with LFS and a few orchids.

    Josh,
    We used to use a freezer in our first chamber (much smaller). We would need a pretty big freezer to do any good with the current chamber. The freezer we used to use is about 3' tall x 2' wide x 1.5' deep and it was able to get an insulated 4 x 4 x 6 chamber in a basement down to 60F each night.

    The current chamber is actually surrounded by an outside chamber, with about a foot of air inbetween the two layers of plastic. This has provided an excellent source of insulation for the chamber at a very cheap cost (for the size of the chamber). There are definitely some easier ways of making a highland chamber if you're wanting to stay pretty small with it (or an ultra highland chamber). You can build a chamber that sits off the floor and surround it in another layer of plastic like I described above except you have a layer of air under the chamber as well. Then, you insulate the ouside of the structure and air condition the insulated layer of air. That way, you get the cold temps from the AC but no humidity drop in the chamber itself. I've tried this setup on a larger scale and it just doesn't work the same, although it might if you have a layer of air under the chamber and use a pretty powerful AC.

    I'll have to get some more up to date pictures, but here are a couple of older pics. These were taken before I made the outside chamber to enclose the original one.
