Hood and Base
The hood and base are made out of Oak, stained, and coated with some polyurethane. The tank fits down about 2 1/2" into the base so that the water in the false bottom isn’t really visible. The hood has the same corner cut outs that the tank had so with the top cover off you could reach down (or pour water) through the hood into the tank without removing the hood from the tank. The other interesting thing about the hood is that there is a piece of wood running parrarell to the bottom of the tank that separates the hood into two halves top, and bottom. This was done to allow me to mount the electronics (ballasts, switches, fans, etc.) in the top and the bulbs in the bottom so that all the junk remains entirely hidden and the only thing you can see is the bulbs. There is also a 1/8” piece of lexan separating the bulbs from the tank. I may add a small piece of eggcrate between the lights and the plastic cover to make the lights not so bright when people are looking up close.

Electronics
The tank has a total of 6 40mm computer fans that serve different functions. Each fan is running through it’s own turn nob potentiometer so that the speed of each fan can be turned up or down. 2 of the fans are mounted on the left back of the hood inside the right side corner. One fan is mounted on the middle back of the tank and circulated air across the electronics and bulbs to keep them cool. Three fans are hanging different places on the tree fern back inside the tank and circulate air inside the tank (VERY important for good air flow with the orchids). Each fan is wired first into a terminal like this:

before it goes through the potentiometer. That was if one burns up or stops running, I can losen a couple of screws and replace it without any hassle. The fans are all running off the same 12V transformer that I use for the mister pump below.

The mister uses a windshield washer pump to pump water through the mister heads. I am using a universal pump from Auto Zone that I bought for $12 but since then I have seen them around for a lot cheaper. Here is an example of one.

I hooked this up to a transformer from an old laptop. It is a 12V 1.4amp transformer. It runs both the fans and the pump. You need a pretty big transformer for the windshield washer pump at least 1 amp (at least for the one I use). The water in and out are both 1/4" hose bibs. I used 1/4" pipe from a drip irrigation supply place. I also bought a bunch of mister heads, and the ones that worked best (really fine mist) are the people mister heads they use for cooling people off on a hot day. If you live where it is dry, you can buy all these drip irrigation parts at Home Depot, but if you aren’t as lucky (like me) you can get everything you need here:

I used the 1GPH misting heads and they seem to work great. It produces a really fine mist. The pump has no problem running two misters, I’m not really sure how many it could drive. One of the only potential drawbacks of the pump is that it is rated to only run for a max of 15 seconds then it needs a 60 second rest to keep from bunning out. I suspect it could run for longer and I intend to test that theory over the next couple of months using a separate pump. This leads to the problem of finding a plug in timer that can be set in 15 second intervals that isn’t so expensive that you just as well buy an expensive pump. I intend in the near future to add a timer circuit like this one:

to turn the pump on for 5 seconds off for 60 seconds on for 5… etc. Then I would run the power through a cheap plug in timer set to be on for 10-15 minutes a day. This would work great, but for now, the mister is turned on and off by a push button switch mounted on the back of the hood, and I just run it a couple of times every morning.
