As you can see I set up a new GH. I made one huge mistake though. The USonic Coolmist Humidifier I got had a digital push button. That means that when I put it on my timers, after if shuts off, it will come back once. The second time, no more mist.

So right now I have it on the bottom shelf running on low 24/7. Its propped up above a very short but long and wide tub filled with wet perlite. The back is sealed to the tub, the sides have strips of kite tyvek spanning the distance from the tub to the side of greenhouse, so the only openings are the bottom of the front where I have to leave the zippers free.

The Humidifier is positioned so its intake sucks air from the outside, I push it up against where i leave the zipper up about 6 inches, Fits nicely, so alot of the humid air is fresh air.

I tried cutting slits and using a fan from the outside for fae bc this way the tops of my trays were becoming covered in myc piss. But the heater nearby the fan caused even more condensation and made the prob worse.

Now I installed 2 80mm CPU fans. One on basically the top left, ducking air in, and the other near the bottom blowing air out. They run 15 min every hr, and the mist is always on still.

Now I don't get condensation and myc piss everywhere, but I have no idea if I am drying them out either... The hpoo block I had in a growbag started pinning EVERYWHERE for its 2nd flush so I took it out of the bag, placed it on a mesh type riser, and the pins are still developing nicely after a day and a half.

I have the option of upping the mist, but 15 minutes is the smallest increment I can fan due to my timers. If i wait longer for the fans condensation starts to get all over the wire rack shelfs.

Basically, do you think I have it dialed in? One meter says 65, though I'm pretty sure it's broken, another shows between 80 and 90 when the fans are off, and goes down to 70 when the fans are on. Another digital I have shows 100% and the wet warning all the time. Fans on or off. LoL

Opinions please. Oh yeah the temp is at a constant 72degrees. The room has finally gotten to a stable temp all around due to the little space heater I have on the opposite side of the room on another timer.

I tried the same exact setup before but ran into 2 problems. The humidifier wasn't potent enough to keep that size tent humid, and the fans that happened to be at the same exact spot as yours, were drying out the sub. So I added one more humidifier to the top shelf faced towards the back so I wouldn't get water on the sub either. I also moved the fans to the bottom of the tent so I was working with the middle shelfs pretty much. The humidifiers weren't as strong as they needed to be for that size greenhouse but I was able to get decent flushes from it. Even grew some edibles in it. But that was just my experience

It looks like my trys are still a tad wet if anything. I had to clean up a lil piss from the 6qt container nearest the top fan. Others look perfect. The unit I'm using is surprisingly strong, and I can always try upping the settings to medium then hi before changing things.

BTW the fans I am using are wired to USB cords, and I could only grab dollar store wall units to plug them into atm. That means they're running at 1.0 volts. Very slow. Venting the very thick mist seems pretty even, and like I said I am not worried about too little humidity, but too much.

I hear most people are running theirs for 15 or 30 min at a time then nothing for a full hr, then repeat the cycle.

If it really is too dry my tray will stop pissing completely and some shrinking will happen around the edges, no?

Metabolites are always a response to a contaminant. Most likely bacterial. Better to leave it, its how mycelium. Fights bacteria. It does it so well it's been used to create antibiotics to fight e. Coli. Healthy mycelium gets inoculated with e. Coli, the metabolites are harvested.

Shrinkage should be expected from a healthy substrate, not necessarily indicative of too dry.

That being said, I'm guessing you still need a bit more FAE and a bit less humidity. I don't think you need to worry about too little humidity unless you stop seeing any condensation inside the chamber.

Throw the fans and cool mist away. They are going to get enough FAE just by opening them once a day to check on them.

Second thing is your substrate only has to be damp; about as damp a PF mix. A thick sub with a min of 1/3 coir will get you through atleast 2 flushes. Any damper and you run a greater risk of contamination.

Substrate should also be above 7.0pH.

 

Lastly stand the martha up vertical. Not its side like in the picture.

 

Once you get the hang of it green houses are the easiest way to grow.

I don't know if you're being serious when you say stand it up vertical...it is.

And there is no way I'm throwing out the fan and coolmists. Already tried without em. Rh holds at 55%. Have you ever used a greenhouse?

So leave all the piss on the top? Even of its pooling?

How will the substrates ever pin without the evaporation trigger?

Can I just throw some dry sterilized verm on top of the trays? Just sprinkle enough to soak up extra wet spots?

Pay no attention to Cue. He's grumpy. And probably naked. But he does know what he's doing.

Pooling has me wondering, that does sound extreme. Use your best judgement, hard to say exactly without actually seeing.

A light casing might help.

First shot is of a block taken from a bag after its first flush. I dunked it, put it back in the back, and saw knotting, and this was right after I got my martha to current settings.

As you can see it see it seems to be doing pretty nicely after putting it in the GH. Forgot to mention it was originally only one half pint PE spawned to 1lb of Outgrows hpoo.

The second shot is of the piss I'm talking about I think it has alot to do with the substrate not being completely flat. It is higher on one side of the tub a little than the other. Oops. It seems to be getting better though.

If I do make a modification I will put the mister on the top shelf elevated by one of those wire crate things like I have the block on. I can take off the top attachment and let the mist just fall down over everything, or point it at the back. Keep in mind it's still on low. Still have medium and hi settings.

However, since the block is doing well, should I leave it for now until the block is done at least?

And why does the app keep turning my pics. They're fine before I upload.

Unless things look otherwise too wet, let it run a few days, keeping an eye on it of course.

Can't explain the glitch. But I've found if you do any kind edit first. Even a minor cropping, and the pictures load correctly.

Subscribed! I've been running an identical setup for about 6 months. Ditch the cool mist humidifier. Mine burned up after bout 2 months after running to high of humidity. Get one of these and run the humidifier outside the tent. https://www.amazon.c...f=yo_pop_ma_swf I found its much more efficient and easier to fill. As for Fae I have a small clip-on fan towards the bottom of my Greenhouse which really only stirs the air around. I need a more efficient way of bringing FAE into the tent. Love your setup I look forward to chatting with you more.

I put a bit of polyfil in the cap to catch the mist and now I'm running the cool mist 24hrs a day.

The fans are on for 15 min, off half hour, repeat. Things are working very very well. Pinsets went from only on the sides and bottoms to what I show you.

All that FAE is very beneficial. The ATL#7 and Tampanensis are even doing well, without any drying of substrate. Meaning no misting and no need to open either.

I with the bit of polyfil in there I only need to refill once every 2 days instead of every day.

Nice pinsets. Every level works, my ATL7 was on the bottom but moved to the top after they started pinning, and I have trays on every shelf doing well.

Check out my other threads to see the ATL#7 and Tampanensis and more pics. These are PF classic. I dont want to spam pics on each of my threads, just prove the setup works well.

I also have the humidifier on the top shelf elevated about 4 inches, so out points toward the back so it hits the plastic then spreads everywhere. It helps with pooling in other parts of the chamber.

I wanted to show how and where I put my slits, and also how I mostly cover my top fan. The bottom one isn't covered at all.

Also, I keep everything totally zippered up now that I use the polyfil mod, and want to specifically say this setup works bc of the fans running at only 1volt when then do run, and the humidifier is on the top shelf, so the cool misted air settles to the bottom, hot air rises, creating convection and keeping the air more evenly humidified than if I kept it at the bottom.

Hey, D'24 and others. We've been chatting here and elsewhere about best build for a martha.

 

I've put my martha together but I'm fanning within the tent. It's a bit too early to tell. I'm not saying it's a fail but but I'm trying to make mods to keep things growing and get some pins on a bin or two so I'd like to 'get it right' and not lose my unpinned bins.

 

I have my fan inside the martha entirely and thus it just circulates humidified air on a timer. I have a bin that was beginning to pin but seems a bit stalled since putting it in the tent. The humi is running on a humidistat and hovering around 85%. Temps are 73 to 78F

 

I could be wrong but I get the sense that perhaps I should have the fan venting from the outside to fan with cool and dry air instead of just fanning with the same moist air.

 

There is also the question of "air exchange". I can guarantee that this thing is leaky enough to get plenty of fresh air from the minuscule amount of myc in the tent. So I don't think it's fresh air per se that is lacking but perhaps intermittent, cooler and dryer air. vs just stirring around the moist warm air.

 

Thoughts on this? Do I need to go with air from outside the tent, cooler and dry air for the timed fanning?

I want to add a very small fan do more evenly distribute the humidity.

I am running an fan on top bringing in fresh air very frequently, so I'm not worried about said prob myself.

Just keep trying things and see if they work. You'll get it eventually

Are both your fans on timer? And what intervals do you use?

Ha I made the same mistake getting an ultransonic mister for my GH with a digital push button too! Got another with the required dial switch, but it seems to only want to work consistently on a completely level surface, on the wire rack shelf of the GH it is being highly inconsistent. I'm thinking I'm going to replace it with this... https://www.amazon.c...5740111_TE_item...and go for the approach that NotFadeAway describes, piping in fog to the GH from outside (with the added bonus it will make it much easier to refill the water tank on the mister, this took a fair amount of precarious manoeuvring before given the size of the mister relative the shelves in the GH).

 

For FAE, I have cut pairs of holes in the GH on each shelf filled with polyfill. I have installed two CPU-USB fans in the GH cover running on the same timer...the one near the bottom vents air IN, the one near the top vents air OUT. Someone on the Shroomery used this setup for successfully fruiting exotics that appreciate good FAE, and I thought this sounded like a good idea. I also have an additional fan wired up inside, timed to coincide with the fogger so as to provide a more even distribution of mist in the GH (an experienced grower on Shroomology recommended the fan/fogger combo for growing Mexicana in particular). I have a few reptile heat mats on in the GH near the base to raise temps a bit, one of them has a tray of wet perlite on to help provide additional humidity between mistings. I'm in the very early stages of using this GH, after having little success with my previous FC setup...I'm trying to fruit P. mexicana 'Chicon Nindo' and P. hoogshagenii 'Semperviva' with the GH at the present time.
