Hi all,
this is a tub used at construction sites to mix concrete. It costs about 6€ and keeps up to 90l of water. I turned it with the open side to the front, and closed that with plexiglass. The bottom of the Plexiglass is mounted with screws to the tub. The upper part can be taken away. On the new "top" is a whole which provides some fresh-air. The Light is a LED-light pretty expensive for the fact that it's very weak. But so I have nearly no electricity consumption (the LED-light has 1W !) and especially no heat. Next to the light there is a PC-fan installed that blows air into the tank. It is plugged into the same clock timer as the light is. Out of the right side there comes a small pipe which provides the tank with water. It is like a raining systems but easier to build and much cheaper.
If you want I can upload further pictures.
Best Greetings,
Kamil
