Martha's - Cool Mist vs. UltraSonic
#8450374 - 05/27/08 12:21 PM (16 years, 7 months ago) |

So I was doing my daily reading here on the Shroomery and decided I have all the necessary supplies to build a Martha to house some tubs.
As par, I've been seeing some conflicting information on whether it's best to use an UltraSonic and Cool Mist combo vs. simply using the Cool Mist alone.
I live in a humid part of the country, so I don't think maintaining the humidity would be too much of a concern, I don't know since my hygrometer has not arrived yet.
Anywho, I was just looking for a little feedback on those who use(d) Martha's and whether or not you using the combo of just the cool mist, and in what cycles do you run your cool mist?
Also, is there any reason why people come up with these elaborate contraptions to funnel their cool mists and US's into their greenhouse from outside the Martha?
It seems like a lot of effort when I could simply put it on the bottom shelf, avoiding having to cut holes into the Marta.
Are people doing this so they dont have to open the martha to refill, create more space in the martha, go for a more contam-resistant environment?

There is no real specific answer to your question.
You make you own system to suite your needs, and even then you need adjust it from time to time. There is just too many variables to say 'this is what always works'
Since you said you have high humidity in your area, I would start with just a cool mist. Run it 30 min on, 2 hours off. Get a decent humidity gage, and check it a lot in the first day. That should give you a good idea of whats going to work for you.
BTW a Martha/GH will hold humidity better when fully loaded. If you can maintain high 90's empty, your in very good shape.

Like d4a2n0k stated, it's mostly a matter of personal need. Generally, if you plan on putting the cool mist inside your martha, you won't likely need the ultrasonic. You will have to find a timing schedule that suits your needs by closley observing the RH levels over the first few days. A coolmist inside the martha doesn't need to run that often considering that it is just recycling already humid air.
The reason that many people pipe their coolmists in from the outside is two-fold. First, it simply provides more shelving space. The biggest reason that I believe warrants piping it in, is that the coolmist is constantly sucking in fresh air from outside the martha, ensuring the mushroom are provided with the FAE that they need.
However, a piped in coolmist doesn't always keep the humidity as high as you may like. This is where an ultrasonic comes in. Additionally, a piped-in coolmist usually runs 24/7 and may wear out quicker.
If you do put the coolmist inside, make sure cut a number of decent sized holes in the martha and have a fan running in the room (not directly pointed at the martha). This will help with FAE.
I have always piped in air from an external coolmist running 24/7. Never needed an ultrasonic. This is what has always worked for me, but you'll need to do a little trial and error to find works best for your situation.

I just ran a coolmist externally 24/7 with perfect conditions. I had no problem with it burning out because I did routinely clean it. Even when using hydrogen peroxide and changing the water often there is still build up on the motor and the impeller. Proper care, in my opinion, is the key to extending the life of the cool mist.
I tried using an ultrasonic but it just caused me more problems than anything. The mist that it shot out was pretty cool looking but I couldnt run it for more than 5 minutes at a time without having tons of water pools at the bottom. This would mean an expensive timer for numerous cycles throughout the day.
If you plan on doing any combo inside your martha you will need something at the bottom to catch excess moisture. A rubbermaid full of perlite works well if you can find one big enough to sit your martha in.

Ultrasonics provide RH, and tons of it. but no FAE. Can drench the place if you're not careful. Coolmists provide adequate RH and strong fresh air exchange. 2 different tools really, it depends on what you are growing. Cubes are a joke and can get by on a coolmist only. Other species may require both depending on your grow chamber area and environment.
The thing about coolmists and ultrasonics is that every setup is different, and there is no "standard". You have to tinker for what you are doing. Grow area, species, environment.

With coolmist setups I usually have people go get a vicks v400 and just drill a 5/8'' hole in the lid. Attach a garden hose and seal with some duct tape and you are good to go. Im a simpleton though

I actually ended up putting the entire units in a double stacked martha and skip the hose business, couldn't be happier. Coolmist for FAE, ultrasonic for RH. With a few timers and the right temperature, you can grow ANY species and tailor the air exchanges/RH to fit your needs.
My oysters and shiitake are in heaven. Fill the tanks probably twice a week. Timers are a beautiful thing.

I wish I had the money to invest in a couple of quality timers. Those little buggers can cost a pretty penny
When I get back into growing I will be sure to do things a bit more professionally

Does anyone know of a resource to safety ratings of different timers? I worry about any potential fire hazard. ~Pixie~

I didnt read all the above posts, but I know this...
A coolmist is for FAE and a untrasonic is for humidity. You cannot put it inside of the martha because it doesnt run as well and it only cycles the stale air in the chamber.
Its best to have a spot above each shelf where humidity/fresh air can enter rather then just one spot at the top.

False, all you need to drain C02 and introduce fresh air is the gap between the bottom of the martha and the floor. In fact, the gaps in the zippers probably provides more than enough fresh air. These are mushrooms, not plants. If they required true fresh air you would have a fan on them 24/7 and constantly be introducing humidity.

Ive never seen a martha with an open bottom? I always used the closed ones.

Oh, when I say Martha I'm referring to a "mini-greenhouse", which I use two of, stacked front to back. If Martha is different and sealed at the bottom, you can open it up.

I make the same assumption. I have always used 4-tier Juliana greenhouses which do have the open bottom

marthas suck, build some monotubs. way cheaper and way more reliable.

Nonsense. A monotub is no more reliable than a martha/greenhouse. And I can't speak on the price of a martha, but my greenhouse setup cost no more than than the multiple monotubs that I have built to produce an equal amount.
For the record, I am a current monotub user due to unrelated reasons.

I have grown in mono tubs before and there is no comparison to a fully stocked and ever growing greenhouse,you don't have all you eggs in one basket in case you have a contamination issue and as I have Pointed out several times once you get a good time line down so you have new casings ready to be moving in when you remove old ones you have a virtual mushroom factory on your hands and can be harvesting and drying mushrooms on a near daily basis,they idea is to always have some trays in every stage of growth so when you toss out one another goes right in

Great Post guys. Just getting my Martha going so I'm just soaking this all up trying to reduce the trial and error. Anyways great tips.
