A great humidifier for small tubs
    #19230528 - 12/05/13 09:54 AM (10 years, 1 month ago)

My shotgun FC kept hovering around 90%. I read the tech years ago and didn't feel like debugging so I searched around for a small humidifier and found...



It's USB powered, cool mist, runs about 4 hours before depleting it's water, and is absolutely the perfect style for a FC :smile:

I don't know the rule on Amazon links, so it's item B006Z04LRM, "Cyanics Sauna Boy Portable Mini Office Bedroom Humidifier USB powered" current $10 and has prime shipping.

Get rid of the hygrometer, get rid of the humidifier...they are doing you no good.

If the SGFC is built to spec, your humidity if fine no matter what some cheap non calibratable electronic hygrometer says....

1/4" holes every 2" in a grid pattern on all 6 sides, filled with 4-5" of moist perlite, in a room with no running fans, raised so that air can pass up thru the holes in the bottom and up thru the perlite.

Ah well, there's likely my problem. I only did 4 sides.

I can't imagine using the humidifier, now that I've got it, is hugely different than perlite humidity.

:whathesaid:

your cheap hygrometer is almost definitely giving you bad readings. They're not calibrated, not made to take temperature into account etc... I'm not a fan of wiki but read the article there on hygrometers and you'll see that it's really quite expensive to make one that works well even meteorologists have problems sometimes.

Fruiting Chamber
A SGFC has 1/4" holes spaces 2 inches apart in a grid patten on all six sides. 4-6 inches of moist perlite. No attachments made to it with any extra things like humidifiers. Optimally the SGFC should be in the middle of a room. No fans should be run in the room with the SGFC, but a cracked window is OK. A humidifier in your house can help to raise the ambient RH but don't put it near your SGFC put it in the other corner of the room if you do decide to run a humidifier at all. The SGFC IMO should have at least 6-12 inches of room from any wall on all 6 sides. This includes finding some sort of raisers to elevate the SGFC off of the surface it's on.
This is what can happen if you make your SGFC the right way.
Here's what will happen if you do it the wrong way. You'll likely rage quit.

Misting and Fanning.
This is a source of much grief and 100's of posts a week here. Misting and fanning is not at all complicated as it needs to be. In general you'll mist your cakes until they glisten(yes they can even with the verm on them) and then fan right after the mist. You can mist your cakes directly and you should. When you notice the cake is no longer glistening you can mist it again and then fan. This occurs on average of 3-5 times a day. Don't worry about sleeping or being gone 12 hours. Just do it when you're around and don't forget about it is all. Fanning is not FAE it's only purpose is to relive the high RH air so that the cakes can get a kickstart on evaporation.

FAE
This is a phenomenon (Fresh air exchange) in a properly built SGFC this is constantly happening. The perlite is naturally cooler than the surrounding air this moves molecules closer to eachother as the lose kinetic energy. This creates low pressure which pulls air up through the bottom holes. As the air moves through the perlite it picks up humidity and keeps the chamber at or above 90%RH. This occurs naturally without the fanning and is why we like to have no fans in the room and is also why fanning after misting is not a replacement for FAE.

You would need to fan several times per hour.
