Misting + Ultrasonics Question
#23889142 - 12/02/16 09:51 PM (7 years, 1 month ago) |
|

In my small indoor chamber I have been solely using ultrasonics to provide the humidity. A friend and I have built a 10ft x 6ft chamber in his garage and to provide the humidity we built an evaporative cooler + 5 ultrasonic heads. In doing so it clicked that in similar sized chambers, some people run just ultrasonics, just misting (non high pressure), or a combination of the two, but I didn't know why.
Are there pros and cons to these 3 methods in regards to pinning, fruit development, first flush yield? Does the misting along with the ultrasonic help to initiate pin sets? Is it just a heck of lot easier to spray it down?

Ultrasonic die pretty fast. You might want to check out the small 'industrial' humidifier they sell on farm tek and other sites. It will last longer , $300

Yea ultrasonics are good but they last maybe 6-12 months before the disks need replacement or the housing is just too corroded. And mistiers actually wet the fruits and surfaces in your chamber giving the fruits water to absorb. Where humidification just increases the humidity to slow evaporation. For your typical oysters you want to firectly mist to bosst yields, shiitake too just not as much as oysters

How about misting equipment. I'm in the market for a new mister bottle and I'm also looking into mister heads (The type that screw into PVC). What are your recommendations for misters grower? The finer the mist the better?

If I remember right, he got them from sprinkler wharehouse online, and be sure to get the anti drip stoppers too. And yes, the finer the better. I was looking at this.

Those netafilm mister look pretty top notch to me. I personally was on a tight budget when I set my foggers up so I went with these
 Super cheap, they work very well and you just punch them into plastic mainline. Although one day I reeaaally want a hydrofogger. But a guy can dream

I'm actually very familiar with netafim. When I worked in the wholesale growing business we use netafim drippers to water hanging basket and a few field of mums that had about 10 thousand pots each. It was a pretty big operation.
We used similar foggers to control heat build up in on of our greenhouses. They were very nice. If I remember correctly they recommend putting a filter inline with some of their products to extend the life of the nozzle.

Ive got a bunch of high pressure brass foggers. If I remember they were like 1\2 gal per hour. Had a stainless screen inside them . Don't recall the brand. That was the new method back in the day. Shut down ventilation fill greenhouse with fog then cycle ventilation back on . Supposedly removing the heat. I've still got drippers for hanging baskets too.

mid pressure systems (200-300psi) are the best middle of the road solution but i guess the ones that run off line pressure are OK too. The high pressure misters I have make 8 micron fog. The humidifan I had made 50 micron fog, the reduced dripping with the high pressure system is noticable. I can fog out the room and still keep the floors pretty dry. previously I would have an inch of standing water at all times just to maintain 90% humidity.

Which high pressure fogged did you go with Drake?

Ultrasonic really seems to work very well for my Oysters and Shiitake. I use a combo system. The overhead misters are just there as a back up in case the fogger fails for some reason. Most foggers suck. The best one I found is the Frapaplas out of Quebec. Great people and all Canadian made. One disc. It's not a cheap unit, but it works consistantly for years without fail. Every part is replaceable. Water on the mushrooms will lead to issues and yields will not be as good without a fogger.

the high pressure system from aeromist.com, 1000psi which is about $900 for the pump but it is like night and day from the humidifan ($1300). I still use the humidifan to keep wind speed up, which helps with evaporation. it's not a problem if you slightly wet your mushrooms as long as you have long enough to evaporate the water.

the system I have has droplet sizes about as small as the disc foggers. But it is good to have backup. Usually when a humidity controller or timer fails on me, it fails open though. Which means on, so I come home to soaked shrooms.

I too am curious which misters you switched to.The ones i use make 70 micron mist, so 8 micron misters would be great! disregard just saw your post

I was just searching around to find basic 101 type information regarding setting up a misting system for a mushroom growroom but was coming up short. Does anyone know of a resource where there is information on designing a misting system? - just the basic stuff like equipment sizing, timing, and sprayer distribution.

I use a hydroponic timer thats adjustable down to secods. I adjust it as needed depending on temps and phase of the grow.

That kind of info could most likely be adapted from the manufacturers web page. For example, http://www.netafimusa.com/greenhouse/products/foggers
They show spacing and overlap for different applications. Timing will be dependent on your growing situation.

We use a hydrofogger and couldn't be happier with it! The owner is a really nice & helpful person too. I'm glad to no longer be using ultra sonic humidifiers.
