This is a pic of the chamber I use to lessen the output of my ultrasonic. I am about to do my first attempt at this and really can't be sure how well it will work. I am also thinking if it still is too much humidity I can put the thing on a timer. I tried to design a low maintance solution that conserved water and didn't need emptied very often.. Also I have put .03 micron eltrostatic filter on the air intake of the humidifier I also plan on a small exit hole for air in the terranium(contructed soley of plexiglas) with a filter on it as well. Let me know your thoughts on this setup. Thanks

That low spot in the tubing on the bottom is gonna give you problems...... you're going to get a water drop in there that will clog the line in no time at all.

You can't have any low spots..... all tubes must start high and travel down with no low spots.

that was my first impression, but actually that is ok, good actually. it's the drain. ideally he wants a water trap there to prevent bypass from the first stage to the other stages. i had one of these setups for a year or so. it never worked like it was supposed to for me. ultrasonic turned all the way down through three stages and it still pumped out way too much fog even with a 1 hour on timer was too much, the timer has to be able to do at least 15 min on times to make it work well at all. a setup i heard of was to run the humidifier off of a motor rheostat to limit the output, i never tried this. my ultrasonic died and i never got another. i may try the ultrasonic on the motor rheostat sometime in the future. i liked the ultrasonic b/c it really was no hassle and pretty maintenance-free. i only had to fill the 2.2 gallon tank every couple weeks. and pick all the shrooms of course

I had a 50 gallon tank that held about 25 cakes. I had an ultrasonic humidifier hooked to 3.5 inch dryer tubing. With the dual timers I could have the humidifier turn on for 15 sec. every hour or for whatever time interval I wanted. I think it was 20 sec. every 4 hours is what I worked out. I could never get it balanced. It was either too dry or too wet. The recommended unit is the "coolmist" according to Hippie. With marajuana high tech is in but with shrooms they love low tech. Spray bottle on, spray bottle off grasshopper.Timers mode c,b

I use a cool mist right now
been on 4 days testing it
constant 90% + humidity, with no condensation
only a little wet perlite in the bottom

works good so far

an expensive timer is the only way to go when using a humidifier. http://www.greenair.com/cyclestat.htm makes a vairiable setting timer that lets you turn it on for anywhere between 8secs to 8 hours. its about $90 but you well have a maintanance free setup with it. worth it in my opinion. my friend had her ultrasonic connected directly to the terrarium 2 mins on every 50 mins. with a small drainage hole on bottom connected to a glass of water by a tube. worked perfect.

you can even just buy a 10 dolllar timer at any hardware store and it will work fine. i set mine up to be on 30 minutes every 3 hours, just put some holes in your terrarium for a little ventilation. mine works fine, totally maintanance free, i've had it for over 3 years now without any problems

About a month ago, I decided to try growing a few shroomies and built two terrariums in a temp controlled walk in closet complete with with drip sheilds, guages and an ultrasonic humidifier. Using liquid mycelium innoculation, verm/BRF spawn as substrate and casing my terrariums with equal layers of wet verm. on bottom and top. I have found that the humidifier is serious overkill running full time, and have had challenges keeping the units in the walk in (brand new building manager keeps coming in to measure and fix EVERYTHING !#@*! )

It has been five days since casing the mix and I already have mucho white fuzz in both units, and have twice (today and yesterday) lightly dusted the exposed mycelium with wet, verm. (to encourage a more even flush) What percentage of the casing surface should be colonized before I initiate pinning? And what about the humidifier, even run through 5 two litre bottles to minimize condensation is it too much? (I am fanning and misting right now). I don't see much on this forum about this kind of tek, but surely someone here has had experience with this kind of casing and would like to offer me a little feedback on this

For the humidifier, I think that you should get a timer for it so then it will only run for like 10 min a day or 5 min every 6 hours or something... The mycelium will pin when it is ready to all you have to do is expose it to light.

a timer would help for the humidifier, as jared said.
as for when to initiate, after about 20-25% of the casing is grown thru.

I read something posted by an electrician about timers being bad for fans.... Which are of course located in humidifiers....


I don't remeber why....

Dr., maybe you're are thinking rheostats are bad for motors? all a timer does is give the thing straight power when it swiches on, like flipping the "on" switch on the unit. they make a special rheostat for motors of some sort.
i had an ultrasonic hooked up for over a year and the fan never went. i did have to take it apart once and oil the motor.
