Just an idea I've been toying with. I have made many mental refinements to it but have not yet built a prototype. Here's the rough idea:
Of course for it to work the grow chamber would have to be air tight with the exception of the ducting from the fan to this box and there would have to be an exhaust hole in the grow chamber. Simple filters could be set up on the exhaust and intake. A timer running every other 15 minutes could turn the air over many times an hour. Like I said, I've never built it but I think it would work. It'd be great for 'set it and forget it' growing. Very simple and with decent air filtration and a little h2o2 there shouldn't be much in the way of contam risk. I'm gonna build one soon and ship it off to nan for testing. What do you guys think? |

looks pretty ingenius, i'd bet that forced air thru perlite would be saturated, a poor man's humidifier. |

How do you keep the perlite wet? Wouldn't the water run through the perlite and just drain out before it could wick the water throughout? Perhaps put the fan at the bottom and flow out the top?  |

Perlite retains water quite well, gravity isn't enough to wick it dry. Water would just need to be added once every few days i'm guessing. I've also been toying with a drip system idea to keep it wet. Nice thing about it (if it works) is that it's smaller than a humidifier, quiet, and could probably be run 24/7 without over humidifying due to no water droplets being blown into the chamber as with regular humidifiers. This way you could keep nearly constant air exchange. |
