Martha Question
#7609639 - 11/08/07 12:44 AM (16 years, 2 months ago) |

Here's the deal. I have a new Martha and I am trying to figure out how to deal with condensation and moisture collecting at the bottom. I intend to use the hydroton/airpump set-up from my PMP to provide FAE at about 300+ gpm exchange, and I hope that that will do the bulk of my humidification, however, I have also purchased a ultrasonic for insurance and have seen the amount of moisture they can leave behind.
So, my question is....
1) With a Ultrasonic running for 5 min every 2 hrs, or so will that require much draining - In Your Experience?
2) What do you think about the PMP-style FAE, and humidification? I have never had condensation within, or without my PMP (always 99%) and I wonder if minimal ultrasonic activity will be enough to balance any shortcomings I might encounter from PMP setup, while also minimizing moisture build up.
3) I have no tools. Humidifier modification is very hard, otherwise...
Thanks

how do you have the ultrasonic hooked up?if your tubing it into the Martha and running pmp with an air pump there would be no need to drain.please explain your setup a little better for more in depth help.

Just running tube from outlet of ultra, and directly into Martha. PMP doesn't quite cover entire footprint of Martha and I am concerned about condensation running down walls and collecting at bottom.

some people put a drip pan from an old refrigerator (check repair shops) with a couple of inches of perlite to help wick moisture back into the air. You can also keep a flap or two open to let fresh air in. Most people look too much on the moisture on not on the FAE. A coolmist might have been a better choice than an ultrasonic.

you can put the martha in a bathtub for drainage or a large shallow tote with perlite to collect condensation drippings and that will help humidity too

My airpumps will push actually more than 300+, more like ~400, so for a chamber of around 200 gal, FAE should be OK. My real issue here is that this operation is intended to be as covert as possible, so the martha is stuffed into a closet, and under a shelf, and there is no room for a drip pan, otherwise....
I guess i'll hope for the best, but do these marthas, generally form condensation on the interior of the walls?

Well, It's as stealth as possible.

I am moving up to bulk, and need the space for the larger batches. This Martha is awful conspicuous, whereas the PMP itself, just looked like a rubbermaid with other rubbermaids.
So, its set up now, and I decided that I wasn't going to worry too much about what the ultrasonic does to RH. I figure that since the PMP base is doing the heavy lifting as far as RH, the ultrasonic is just insurance.
I do have another question though. Will the mist from the ultrasonic coming in contact with my cases, which are fruiting, have any negative impact on them? Or not?
