project greenhouse

I have been expermenting with different designs and this one seems to be the best so far. I haven?t seen anyone use a ultrasonic with this design so if it works then I am calling it "zerohero?s glorous greenhouse tek that even monkeys can use". FM from nansnook used it but he had a fogger. I didn?t have a fogger but I had a ultrasonic humifier I thought this might be a good way to fix the common problem that most ultrasonics are plagued with(to much moisture). the details: the hepa fan is attached to a small clear tub that allows the air to flow with great effiency. that is attached to a PVC tube that stick stickes out of the storage bin(mixing bin) by an inch at least. the ultrasonic it attach at the bottom of the storage bin(mount it flush with the bin) and the fitting is made smaller than the PVC pipe leading to the greenhouse to create a positve pressure(this is important b/c the humidy needs to be pulled out and not have the air flow into the ultrasonic humifier. I had problem before with this but I think this will correct it.) the storage bin is the mixing bin for the dry and humidy air. moisture will form and it will travel back into the ultrasonic. that why I said it has to be flush with the storage bin. the air will then flow into the PVC piping and then travels into the greenhouse where the proper air exchange and humidy are met. I have a similar design as this now but the storage bin is key as I have to usually change out my ultrasonic every with fresh water.. now the excess water will flow into the ultrasonic. does anyone have any suggestion. FM homer system worked great with the fogger unit and I figure the same with the ultrasonic. I will post pictures when I complete the project. peace zeorhero

Why not put the humidifier inside a bin with a hepa filter on it? The humidifier sucks air in to use and trhat air is unclean...

No point in having the hepa, if the ultra sonic is pumping regular air...

Good observation Jared. I would suggest placing the ultrasonic into a filtered chamber. Also make sure that everything up to the fruiting chamber is sealed, otherwise there is little benefit in using a HEPA filter over any standard filter. Joshua

I think it's a good design, one that is definitely worth experimenting with. I don't know that I would count a HEPA filter out under any circumstance

good idea! I will rig it to reflect that. the only thing is that I have never had a contam from air from a ultrasonic.. I find that if you provide enough air exchange the risk of contams go down next to nothing where contams will be in the air or not... thats provided you would in a clean enviroment or not. but your idea is one I will use to take that needed step.

He means that the ultrasonic does circulate air, if this air is not filtered and then allowed to mix with HEPA filtered air, you have then reduced your set-up to sub-HEPA standards.

sorry.. after reading my post.. I determined I was to stoned to converse! I deleted most of it b/c I didnt' read it right the first time. sorry.
yeah I will put a hepa filter on the ultrasonic then.... is that the only suggestion so far? is there anyway to improve it? other than what was said.

it will also save you space...you wont need those other bins, just theone with the humidifier on it. Also why not use garden hose or plastic hose? Its easier to deal with if you have to move it or something....

Just want to point out that the fogger that FM uses is ultrasonic. It's just a different configuration, but works just like an ultrasonic humidifer. Rather than having it's own resevoir though, it's just the active part of an ultrasonic, and sits in a resevoir you supply (a bucket in FM's case).
So your basic items are the same as his, follow his lead.

This has been something I have been tossing around in my head for quite some time.
It'll take me a day to write up what I have formally. But keep your eyes peeled.

yeah I noticed the fogger was the same as my ultrasonic.. they work the same... I should jsut that and call it quits.. I mean fogger only cost like 30 bucks at most.. but I really want to get the ultrasonic to work....
I will follow his lead.. but I need to make sure the ultrasonic is filtering clean air in there first... but it looks like it will work with ease.. now to start building.
yidakiman - I will interested when you design it.. pm a link once yoiu make it.

What I meant was fogger=ultrasonic, no difference. Use what you have.
Also, now that I look at it, I think your design is fine. Unless you have some kindof US I've never seen, they don't really need to be filtered. Every US hummer I've ever seen pumps out absolutely no air, just water vapor. If the hummer is kept clean (a very little iodine in the water will do the trick), then there is no reason to filter the humidity it puts out.
Think about it, US hummers have a resevoir that is sealed, and a device that uses ultrasonic waves to atomize the water particles. That's it, no fan, no air intake, nothing. As long as the water is clean, the mist will be clean too.

I tooled around in photoshop long enough to figure out that I can't draw this thing. The greenhouse itself will be constructed of PVC piping and the piping will be used to route fresh humid air throughout the greenhouse. Constant airexchange and humidification via a floating fogger inside a 5 gal bucket and pushing air with a CPU fan. The dimensions of the new greenhouse will be 6feet tall, five feet long, and two feet deep. The volume fo the greenhouse would be 60 Feet^3. Blueprints indicate that it can house eight columns 4 feet tall and 6 inches in diameter. That might be a little tight, but it's only a forecast. A fan that moved only 10 cfm of air would be satisfactory. A positive pressure environment would reduce the cfm slightly enough to give me around 5 air exchanges per hour, enough for any species. But this is primarily designed for oysters that are very sensitive to high CO2 levels. But shelves can also be added for tray or block culture. I was planning one shelf to be permenant, at 24 inches. I don't want anything growing under 24inches above the floor. My oyster columns will rest their weight on this shelf. Using the same schematic for this bottom shelf, shelves can be added at any interval, although at this point I plan 12 inch intervals. Thats four shelves for a total of 40sq ft of cropping space. The use of shelving is also the reason that the piping will be used as routing for humidity. When the greenhouse has only columns, a descending fog environment would be fine because it would have a lot of freedom to move. But when shelves are nearly covered with blocks or trays airflow is restricted. Thus I would use the piping to route the humid air equally to each shelf.

What are you using to cover the whole thing with? Jus t a clear plastic drape? What will the shelves be made out of?

I covered my current shelf terrerium with 6 mil contruction grade drop plastic and I plan the same for the new one .

how did you cover the bottom and make it leak proof?

thanks for the input mycofile!
I thought a US would work fine with the risk of contams. I still need to build this device.
to hold up the storage bin will be a little table. then the air and US get routed in there. I really hope this works.. but like mycofile said.. its basically like FM homer system but with a US.

Here are some pics of my current shelf terrerium.
Excluding the front side "door", there are three pieces of plastic; top, bottom and the other three vertical sides. First I did the top and bottom because they were the smaller surfaces. As you can see the plastic is folded over the edges and doubled up. It was stuck down with spray adhesive.
Here it is closed up. Self adhesive velcro holds the door in place. The adhesive has given me a lot of trouble. It seems to stick to the door piece fine, but it comes off the shelf.
And finally here it is opened up. When in operation, the bottom is slightly open.
If you look really carefully, the floor seems to have a beige sheen to it. That is because it is covered in the very same plastic. The plastic has two functions. It prevents contams, dirt and etc in the carpet from entering the air and it prevents dirt from soiling the carpet.
I've found that only carelessness will rip or poke holes this plastic, so I guess that anything thinner would be fairly fragile. When I bought the plastic I simply bought the thickest stuff I could find. It is 6 mil, but I think 8 mil is in circulation. It is construction grade drop plastic.
