Lowering fruiting room tempeartures
    #26849629 - 07/28/20 10:19 AM (3 years, 5 months ago)

How do you guys with larger fruiting chambers deal with temperature without lowering your RH too much?

I have a ~200sqft room framed out inside my insulated stand alone garage. The fruiting room is also insulated with 1” polyiso panels. Outside temperature this time of year are hitting 85-95°F and inside the garage is typically around 85°F. Inside the fruiting room is a bit lower, but still warmer than I would like. Because it is so insulated in there the temperatures tend to go up during the day then stay around 80°F at night and during the day inside the FC. All in all warmer than I would like.

I yesterday I added a 400cuft 6” vent van in the ceiling of the main garage which will help things cool off at night. With the size of my garage I calculated it will replace the air in about 20min. I’ve also added a 10,000btu AC (rated for a 300sqft room) unit inside the FC, however when I run the AC my humidity dips from 90% RH to around 60%. I’m using a 12 disk ultrasonic for humidity.

During the non summer months I’m all good, but when it gets too hot outside I struggle to keep my temperatures down. So I’m trying to puzzle out how to deal with it without lowering my RH too much. I’ve seen some people make a little pre-conditioning room for their AC units then pipe that air through their humidifier so it isn’t so dry. That could be an option, but I’m wondering if there is an easier solution before I embark on that construction project.

Any thoughts and input would be greatly appreciated.

Go to high-pressure mist and get rid of the 12 disk pond fogger. I have a kit that will hook to a pressure washer. But if I were you I would go with building a cat pump misting system.



Where I would buy my pump...

I don't think that AC unit is going to be big enough either.

Will that solve my temperature problems? The fogger is working quite well at keeping my humidity up, my main issue right now is the temperatures.

What I was saying is when you cool the room with the AC you said the humidity drops. So go to a better humidification system. I don't see that 12 disks being big enough for that size room anyway without running constantly. The high-pressure mist will cool the room a little but you will need to use an AC to cool it more. That AC you got is not going to be big enough either with the air exchanges you need to do.

just ac your garage room the fruiting chamber is in. If you leave your AC inside your fc instead of outside it your AC will clog shortly and die. Then pipe your humidifier air from that to your FC.

Okay, so what you guys are saying is get a larger AC unit and AC the main part of the garage? The garage is insulated, but not super well, so I’m a bit concerned with energy costs if I have to condition that entire space which is why I was trying to just AC my fruiting chamber. The garage itself is about 15’x25’ with 15’ ceilings.

I’m thinking the solution may be to frame out a smaller room with extra insulation to house the AC unit so its won’t get clogged with spore from then pipe that cold air from there into my FC. Would that work instead of AC in the entire garage?

I’m open to building a new humidification system if necessary, but right now I’d like to figure out how to best solve my heat issues.

Yes only cool the fruiting chamber. From what I understand the fruiting chamber is 200 SF. If I remember correctly you need an AC unit that is around 3 times the size that you would normally use to cool the room. This is due to blocks creating heat and the air exchanges you need to do.

Ohhh, okay. That’s the part I wasn’t understanding. My FC is indeed only 200sqft, which is why I bought the AC that was rated for 300sqft, but because of air exchanges and everything I’ll need something bigger, more like a 14000btu AC. Is that right?

You were saying if I get a better humidification system I won’t have the dips I’m having when I turn the AC on. Is that right? Do you have your AC inside your fruiting chamber?

Depends on whether it will work on a few things. Is the FC insulated enough to prevent the outside heat from the garage to counter the cold you are piping into the FC. I've seen that issue. If that doesn't work you could make a frame around your FC about 1-2ft. Call it air insulation. And AC that and have a fan blowing the cold air all the way around it. So you have a room within a room of sorts. I know that can work very well.

Yea the Air exchanges demand the much larger capacity to keep up with pulling all the cooled air out for the FAE. Yea, I think my shed is 150 2/ft. The FC is smaller inside. And I think it minimum needed 11k or 12k btu.. I went 14k just in case. You may need an 18k at least. You might want to look into a dual inverter window AC. Not sure if they are the best best or whatever but I think they run cheaper than other types and its what they use in larger units usually but they got it down to some smaller sizes such as 14k and 18k to spread the savings and pwoer .. or something like that I think.

I think you need at least a 20000 BTU AC. Like I said That is from research I have done.

Yes, a high-pressure system will be able to keep up with the humidity drop. I run a high-pressure system in a small room 10' x 4' (I build it from a Pressure washer) and it runs for 10 seconds every 10 minutes with air constantly being pulled out of the room 24/7. So a high-pressure system especially one like I gave you a link to will solve the humidity problem. The system I built would probably be enough but I have never tested it on a bigger room. But it would just mean you would need more misters. Either way you go DO NOT buy slip lock connectors buy compression connectors. I have them for cheaper than anywhere around. So contact me if you decide to do the high-pressure system.

Got it. My FC is pretty well insulated, enough to have it be about 10°F cooler than the surrounding garage. It still warms up as the air in the garage warms, but certainly not as quickly. Today seemed to be cooler overall which I think was because of my new ceiling vent fan.

I’ll definitely look into some more options such as the dual inverter window AC you mentioned. Unfortunately I’m not going to be able to build a 1-2’ dead air space around the FC just due to space constraints, so I’m really hoping I can figure out a solution between my ceiling vent fan and some AC. If I *really* need to I suppose I could put another layer of insulation around the entire FC, but ultimately the vent fan inside the FC is pulling air from the garage into the room, so if its warm out there it will eventually warm up inside the FC.

Out of curiosity, what temperature to you typically keep your FC at?

What’s your RH with your system running like that?

It sounds to me like an attic vent fan may be needed to vent the garage around your fruiting chamber.

My pump kicks on at 90% and kicks off at 93% but the humidity keeps rising to 97% after the pump kicks off. My humidity sensor is not fast enough to keep up with how fast the humidity rises. The pump only runs for like 10 seconds every 10 minutes to make that drastic of a change in the rooms hummidity. I also have an exhaust fan running constantly that causes fresh air to be pulled into my room constantly. So in other words I am running a passive intake air system.

Right if your vent fan is pulling in the hot air it will warm up. And if your exhaust is pulling out all your cold.. you need to supply more.. And then does all this pull in enough cold air quick enough to keep that room cool. That is the balancing act. And yes, an extra layer of insulation can help if your walls are heating up from outside forces. oh as a side note even though you don't have the room for it, the 1-2 ft air buffer with a fan blowing the air completely around it is just another way of doing a plenum. Which also allows for not perfectly sealed FC chambers so that only cold air gets pulled in.

I run this fruiting chamber when it is running, I have 2, around 70 F, though I plan on running it colder. The other one I have I run between 70-72 F. That one is in the house so the temp kinda depends on how cold we feel like living. :lol:

I just installed an attic vent fan two days ago. It is a 400cfm 6" fan so in theory should remove all the air in about every 15min. Yesterday's temperature readings we're very encouraging with my FCs temperature dropping all day. It was still quite warm in there but way better than just seeing the temperature rise all day. I'm curious how it will be today since last night it got down to about 64F.

As for the humidity, that sounds like exactly what I need to keep my humidity up while running fresh air through there. As of right now I have my FC vent fan on a repeat cycle but it's also apparent to me I'm not getting enough FAE. Also when the fan does kick on the humidity drops dramatically.

Perhaps between the vent fan and a new humidity system is be able to drop the temperature to something more workable...

What size pump would you recommend from that link you provided?

Have you ever considered chilling the water you use in your mister system as a way of dropping the temperature? It was a thought I had yesterday but wasn't sure how viable it is.

Got it. It seems like I have multiple issues going on here! So I'm gonna do my best to solve for one at a time... The attic vent fan really seems to be helping cool the FC by cooling the air that's being pulled in. So that is a start. I think most likely I'll need to upgrade the humidity system then add a larger AC unit in a pre conditioning box.

Ugh... I was hoping this would be a simple fix but it's become apparent to me I've got some bigger issues at play.

If you Buy a cat pump just make sure you get one with the pulse hose. If money is a concern and you can not afford the cat pump your best bet is to just buy my system It is much cheaper and you could have it installed quickly. My system has been running for 3 years with not one problem. Either way I will cut you a deal on the misters and connectors since from what I understand you are going to need 50 pcs of each of the connectors and mist nozzles. I built my kit to make it long enough so I could afford to buy the cat pump and then I was going to replace the pressure washer with the cat pump but this thing is like the energizer bunny it keeps going and going and going. I did not expect it to last 3 years but I have no complaints. I don't have to do any maintenance to keep it running either. I have not even changed the water filters yet. Either way, you go I am here to help if you need it just PM me.

Yea and If you are not venting the back of your window AC outside you will be heating up the garage which will make the job of cooling your FC down even harder since that would heat up the FC walls. And if you try and use cool air from inside the garage on the intake part of the back part of the AC and just vent the backside you will pull all the cooler air from the garage outside sucking in hot air from outside ... DOH

:whathesaid:

I forgot to mention on the cat pump at the end of the serial # if there is a P it has the pulse hose if it does not have the P it does not come with the pulse hose

Example...

CAT 1CX050RA5P this one has the pulse hose. I am not saying buy that one I am just saying it has the pulse hose because of the P at the end.

I just returned that 10000btu unit, but when it was set up it was venting into the main garage...so yeah doing exactly what you described. I was hoping my attic vent fan would vent all that extra heat. But I now see how optimistic that was.  :facepalm:

I do have the option of venting it out a window, but that will take some fairly major surgery. I'm down to do it, but want to do it right the first time so I'm not having to remove walls from my FC multiple times.

I think what I want to do first is deal with my humidity drop then address the heat. With the attic vent fan alone I'm seeing some pretty impressive temperature drops. It's not quite to where I want it, but starting to get a lot closer. If I'm able to run my FC vent fan all the time without the humidity dropping I expect I'll be able to get it even lower. Possibly to where I don't need much AC at all! But again that may be too optimistic.

Unfortunately I cannot grow in a basement. I now see how that would be the best way to go because of the passive cooling. Perhaps in my next place!

Yea ask me how I know all this.... I've tried it all trying to figure out how to get my shed to work without having to cut a hole in the side. And being broke as something or other with 2 smaller window ACs lying around. I've also watched a few videos on people trying basically what you did but they tried venting it out the window with the AC blowing inside inner room but the back portion sitting in its own room and pipe vented out the window right near it ... heat city even that way. What I haven't seen tried though is insulated duct used. Would it be enough to prevent the heat from rising in the room it is used? they have r8 at lowes for 25' for $60 or $70 or something like that.

So how exactly is your humidity dropping? You are using a 12 disc right?  is your FC air tight? Is it pulling the mist from a humidi bucket outside the FC so that ALL new air to the FC has to run over the water and mist when it is misting? Is the humidi chamber air tight? I know when I don't do it this way I have humidity problems and my disc fogger can't keep up. But when I changed it to being able to answer yes on those questions, besides the 12 disc, my humidity problem of it not keeping up went away. That and the inkbird controller most seem to use. And based upon the size of my current FC I should need a bigger amount of discs to keep RH than what I am using according to conventional mushroom growing wisdom. But I had looked at the math before I bought thew smaller disc fogger. When I first tried it. It wasn't all air tight and I had a fan on the humidibucket...  that failed horribly. But change it around to air tight and only using the exhaust fan on the FC to pull the mist and air through and it works like a champ.

For the most part the FC is air tight. There is a gap under the plastic sheeting door that pulls in when the FC vent fan kicks on. I currently have the fan on a timer so it pulls in air and that's when the humidity drops. The longer the fan is on the lower it drops but typically not doesn't go below 79%. If I were to run the fan all the time the humidibucket wouldn't be able to keep up at all.

I would fix it so it is air tight. Other wise it causes not humid air to get pulled in. Then your humidibucket has to work even harder. :thumbdown: I had done that originally like you are and had HUGE humidity problems..

Can you slow the fan down any? I do that. My circulation fan inside is on low and I try and get my exhaust fan as low as possible so it doesn't suck out my humidity too quickly. I also have the humidibucket output right next to the circulation fan so it spreads the humidity to the shrooms, where I want it. I do not need thick fog to achieve max humidity very shortly. I just had to dial everything in and make it air tight so that only humidified air is getting in. Also my door is just cheapo plastic drop cloth for painting. The exhaust pulls the plastic air tight. So, you could easily just take some pieces of plastic and fill in your cracks 'n crevices and let the exhaust pull it tight.

My humidity only drops when the humidibucket isn't fogging and it doesn't drop quickly. I get big shrooms and the only problems I am having is they are getting so big 1 fell off the bag or pulling the bag from the shelf since I am side fruiting.. hehe

Right now my humidity range is 82.5 - 92.5 %. I only turned it up above 90 because its been humid around here lately and the fogger wasn't kicking on enough so the shrooms dried out one week too much on the edges cracking. 85-95% everything got too soaked.

Seagu, doesn’t the air have to come from somewhere? I don’t fully understand how it would work to have a fully sealed room.

Since putting in the 6” “attic fan” at the top of the garage my FC temps have been pretty stable in the low 70s, waaaay better than the high 80s where they were. Now I’m more seriously looking into if I need another humidification system if I am going to keep my FC vent fan on more to provide more FAE.

SHROOMSISAY, with the high pressure system you have do ever have issues with sediment buildup? I was talking to a buddy of mine and he was saying unless you have it hooked up to a reverse osmosis system or something that that type of system clogs up super fast. What has your experience been with this?

The air comes from outside the FC. AC that space. But the AC'd air only gets into the fruiting chamber by traveling through the humidifier and thus also you are always getting humidified air, to some level or another. If you make the intake on your humidifier smaller than your exhaust on your FC then it will have a nice sucking on the walls and such to help be able to seal the cracks with plastic drop sheeting or whatever else you want to use. If your door and walls are not air tight. But that makes it easier to seal up the cracks for me. I don't even need a door. How big this scales.. I haven't gotten there yet.. but working on it. For example. My exhaust is 4". I just took some piping and stuck it inside to see how many would fit. They would be smaller of course.

You can kinda get an idea for some of the science if you look up about ducts and such and changing size of piping and air flow speed and cfm, air pressure.. or some such terminology. It has been little bit since I looked it up.

I use a filter and do not have to do anything like cleaning as you do with a pond fogger. I have been running my system for 3 years now and I have not even had to change the filters. This will be different for everyone depending on the original quality of your water. Here is the filter I use...

https://www.amazon.com/gp/product/B079NX153V/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I will give you a good deal on a system if you are interested. You will just have to buy a filter and a pressure washer.

For example.. my small setup that I get a nice amount each week:  Before I put the plastic on and hooked up the exhaust pipe to the inline fan you can see at the window.

And after plastic : Notice how the exhaust pulls all the plastic tight. So the only air allowed to get into the FC must go through my humidifier. Which, quite conveniently the 3 intake pipes are right above the HVAC register.

Everyone said I would need at a minimum for that size 6 discs.. I do not need 6 discs. I only need 3 discs and they will soak everything. Works awesome. :thumbup: :thumbup:

I plan on doing the same or similar to my shed when my weekly sales stay steady and or maybe just slightly increase. Which by the way tons of repeat customers last week coming up raving about the mushrooms in front of others, who then eagerly bought from me. :dancer:

Ah, awesome that makes sense and I think it would be good for me to filter my water anyway. I’ve noticed quite a bit of rust in it when it comes straight out of the hose. As for the high pressure system, I’ve been thinking about this a lot lately and I’m ready to make the jump. I think I’d prefer to get one of those little pumps over the pressure washer however. I’m gonna shoot you a PM right now about the nozzles and how you have everything setup.

Those little pumps will get everything wet they will not do what you want. To do it right and not have to do it over you need high pressure 1000 psi those pumps put out 105 psi if I am not mistaken.

I am not an expert on the pressure system.... Someone on here though did tell me they have been using for years regular pressured misting systems with no problems.. the pressure that comes out of the faucet type..  :shrug:

Wait... I’m confused. Didn’t you link to a pump earlier in this thread saying that you would recommend using it? I am talking about using the little pump you linked to vs the pressure washer.

It was not me that put that link out there. I tried everything before I built my kit. I did not try one of those pumps because it is so low of pressure it is just going to get everything wet. My water pressure is 65 psi and those pumps say 60-70 psi so there would be no difference for me. I can not find the site now but it said that you need 800 psi to have flash evaporation of the water droplets. If you don't have flash evaporation you are going to get things wet. But hey I say try it out and I will be here. After you get all the mold out of your room.

I'm sorry, but I am still confused. You posted a link to a pump you were recommending in the first page of this thread. I don't know what pump you're talking about now that won't work but I am referring to the one you linked to.

Link to your post: https://www.shroomery.org/forums/showflat.php/Number/26849711#26849711

In any case, I do need to get something up and running that works. So what would you recommend?

According to my understanding I can use a pressure washer (like you do) or a CAT pump. I have the inline water running through a filter which then goes to the pump which presumably goes to hosing with sprayers attached. Is that about right?

It really depends on your budget. The link above is for a real mist pump actually it is one of the best pumps you can buy. But once you put it all together it will cost between $700 and $800 the cat pump in the video I posted can be run for very long times. like days or weeks. I sell a kit for a fraction of the $600 that is high pressure also and works great. it uses a pressure washer and I have not had a problem in 3 years with it. It only has to run for 10 to 15 seconds every 10 minutes. to keep my humidity between 90 and 97%. I sent you a PM about it and what you need so check your messages. The cat pump is a long term humidification system but it will get expensive. Especially when the pump will only run for very short cycles. I was going to buy the cat pump and I built my system to just get me through. But the system I built is like the energizer bunny it keeps going and going and going. So I have not even thought about buying the cat pump again.
