Inspired by homer's post on his ventilation setup, I decided it was time my plants received better treatment. This idea also comes from when I grew [legal] mushrooms in a terrarium. It's amazing how you can apply bits and pieces from here and there.
I realise I could just buy a cool mist humidifier, but the idea has never tempted me.
I primarily grow highland Nepenthes - the terrarium used to sit on the windowsill infront of a window, which I'd crack open in the evening to cool the plants all throught the night. This method yielded satisfactory results (54F - 62F), but sleeping in the 50Fs wasn't always comfortable, and the humidity in the tank used to drop instead of rise. Also, the terrarium didn't look particularly good on that narrow windowsill.
I'll let the pics do most of the explaining.
Here we see the fan (cheap clip-on), the front wrapped in clear plastic, which narrows down to the 32mm "waste" pipe. The other end of the pipe is inserted in a practically airtight polystyrene box (in which a plant arrived, hence the tape and tatty appearance) which houses the mini fogger and of course the water that feeds it. The outlet pipe then leads into the terrarium.
At night the fan sits face up on the open window.
I was afraid the fan wouldn't have the umph but it manages well for the moment.
...and this is what the terrarium looks like 20 seconds after my ghetto cooling humidifier turns on.
So far so good, but the fan makes a racket. There's lots of room for improvement, and the first is to cut the pipe leading from the fan alot shorter (which will be done in about 10 minutes). Eventually buying a more efficient fan is next, to increase cooling and sleep quality [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_l_32.gif[/img] I'm thinking along the lines of a bathroom extractor fan. After that would be the reservoir and the overall appearance of the setup.
I'm sure I forgot to mention a few things, but I can say the plants have shown noticeable improvements, and to me this is the most important factor. Please do comment if you have any ideas for improvement!
