Ultrasonic Humidifier setup question
#17319886 - 12/02/12 10:44 AM (12 years, 1 month ago) |

Hey guys I'm growing for the first time and I've just built my terrarium using an ultrasonic humidifier. I've heard alot of people saying humidifiers put out too much moisture but mine seems to me made for babies and I'm unsure. Following the pf tek, I set it up so only a little fog was seen in the last 2-liter. But it didn't seem to really be building up any fog in the actual terrarium. I plugged up the air exchange hole on the bottom to make sure everything isn't escaping from the top. It wasn't. So my question is this. Am I supposed to be able to see mist in the air in the terrarium? I can post a pic of my setup if needbe.

If you insist on using a Humidifier, don't use an Ultrasonic for your Fruiting Chamber... They can and more then likely will saturate your substrate. Use the Impeller type.
Also I'm not sure what Terrarium you are planning on using. But humidifiers work best in Greenhouse/Martha Setups.
If I were you I would search around the forum and find something suitable for you, that will work best.

I understand alot of people are not down with ultrasonics for a small operation but I chose this method after some research and this sounded like the most promising way to go for a first time grow. I've already built the whole thing to the specifications given in the pf, I just need to tweak it. Again, with the size and power of this given humidifier, which is a little polar bear that blows fog out of its nose, and the fact that I'm not casing, which I've heard means oversaturation is less of an concern, I'm really more worried the tub isn't getting humid enough. I'll probably break down and get a hydrometer but I've heard they're inaccurate. I just want to know, so I know if I'm in the ballpark, humidity-wise, how visible should the fog be in the tub if I'm using an ultrasonic setup?

Not visible. If it's visible it's over-saturated. Meaning the mist can't mix with the air.

What fruiting chamber are you exactly using? The SGFC? Because for 1, Cubensis don't benifit from a casing layer. And for 2, they will still saturate your substrates.
If your using the SGFC, just run the Ultrasonic in the same room. A properly built SGFC will give you the desired Humidity, no Hygrometer needed.

correct, and if you keep your rh up in the room by running the humidfier you wont have to rewet your perlite as quickly, and youll have to mist less often, this is especially true if you live in areas with low rh

Thanks cloudpersona for actually answering my question instead of trying to sell me on the sgfc which is not really the right option for me right now. Right now, I'm using a very small setup to grow straight off my half pint cakes, of which I have 8, all either pretty much fully colonized or fully colonized and pinning. We fed 3/8 plastic tubing into the polar bear's nose and sealed it with silicon glue, fed it through 2- 2 liters and then into the terrarium using rubber grommets which don't appear to be leaking. As for the terrarium itself, I'm using a 30 qt rubbermaid container with the tubing coming in a hole I drilled in the side towards the top and I have the gas exchange hole in the bottom with some metal mesh raised a 1/2" to set the cakes on.

Well I can guarantee your results will be poorer than a SGFC, but it's your choice.

Ultrasonics are fine, just don't run them all the time.

Im in the process of building a sgfc/greenhouse mod. I think ill call it a redhouse. lol. Its a red plastic bin w 40 LEDs installed in the lid for 3500 lumens of 7000K. With all the holes cut like a sgfc. A resevoir for a Tiny ultrasonic mister. A small humidity meter. 1 micron polyester filter media on all sides. With an outward pointing fan sitting on the top. A slightly modified 250 Watt computer power supply. 2 resistors.
The fan, lights, and mister all have seperate timers with programability to 5 minute increments.
Its half done of anyone wants to see pics. 
Im going to do a dry run or 2 to work the microclimate control out, and aleviate potential humidity caveats.

I have to install 20 more LED's Yet. These just are not bright enough. I ordered them last night. I ordered the rest of the componants last night as well. I probably got 60 bucks wrapped up in this thing total so far.

Technically the leds are half 6000k and half 8000k. you can see i already made the holes for the new leds in the first pic. I have an unlimited amount of commodity computer hardware to work with. As you can see this thing is wired with cat5. lol Im also wondering if this thing will require perlite or not. Ill do testing and find out. The bottom has slits, and the plastic tray in the bottom is the bottom of a laundry basket so I have a tray to set my cakes on. My aim is to fruit 3 large bag cakes at a time in here. We'll see, and Ill post updates, and perhaps even make a tek, if anyone is interested.
The FAE and Misting will happen on a schedule for a set and forget operation. With a consistantly clean air source in even the dusties houses.

Terrariums do best with some kind of passive air exchange. Ultrasonics can be nice, and are a good source of mist, but you'll either want to use it manually, or use a variable repeat cycle timer (which could be considered expensive for a tub).

Are you using the bottles to diffuse the mist? not sure... Just get a humidity meter, and test it before you put shrooms in it. From what i can tell the biggest mistake is making a mod, and running with the hope of success without doing the microclimate troubleshooting first.

Yeah the bottles are to diffuse the mist to prevent oversaturation. But you sold me on getting a hydrometer, I'm just gonna order one
