I build my hoods too. This is the one over my 135 gallon viv. Its built out of 1/2 sanded plywood and pine. It sets on the to of the tank and bolts to the plastic lip. Everything is organized into layers: screen, then 6 T-12 40 Watt bulbs, a layer of MDF coated with aluminium foil tape, above all that are the vent and circulation fans and the plumbing for an irrigation system I never finished. It is hinged in the back with a 72in piano hing. It works well, but it is kind of heavy to lift. All the balast and controls are in the stand below.

Hood open:


Controls:


The tank doesn't look the same anymore, but the stand and hood do. So here they are:

I had a friend of mind design a cycle timer for me... The way it works is this...
I still use my regular 1 min timer, which is connected to the cycle timer. The cycle timer only turns on for the duration of a cycle that you can select with a potentiometer. Basically once power is applied to the timer it will go off after the cycle time.

I've recently improved my misting system too... Right now I have it connected directly to my RO filter/tank setup, then the tube feeds into a selenoid valve, which goes into the selenoid pump, which then pushes water through a 11 port manifold to each tank. At the end of each line I have non drip nozzles that require a min pressure to operate. Once the pump stops, there is no sputter. I have it set for a approx 7sec cycle every 60 minutes. Works like a charm... Oh, yeah, all my nozzles are adjustable and everything is push fittings, none of that steel ring clamp non sense. Once I finish my tanks I'll post info on my rack setup.



If you want I can ask him if he'd build you one.

Part of the yet un-completed irrigation system. It conects to a solenoid. The only problem is the minmium setting is for 1 min.
