Tub Trouble Blues...
    #10044145 - 03/26/09 06:33 AM (15 years, 6 days ago)

Hey guys I recently built a 28 gallon FC just like this. http://www.shroomery.org/forums/showflat.php/Number/5292458#5292458

I got the fan running 5 min on low every 4 hours. And 12 feet of led rope light going 12/12.

Now the first problem i have is with it only keeping 90% humidity.(The hygrometer is calibrated and working right)
I think this is from it not getting enough air exchange.

The next, is that sometimes when i check the humidity it smells like shit. Which iam pretty sure is from the water in the perlite getting stale. Also i think this is from not enough air exchange.

Now this is what i have come up with from looking around on the site and wanted to see if you guys think this will solve my problems. I Will add a 30 gallon fish tank air pump and two bubble wands. I will lay the two bubble wands about 18in long, along the bottom of the tub. Then add enough water to submerge the wands. Iam concerned about having sitting water in my FC b/c of contams, but will the air flowing through the water keep it from getting stale? Next i will cover with 5 inches of soaked perlite. I will keep the air pump in the fan box to get filtered air pumped in. Then run the tubes into the tub via one of the PVC pipes stuffed with poly and then connect them to the wands. I will run the pump 24/7, along with the fan 5 min every 4 hours, unless you think otherwise. I got the idea from this tek. http://www.shroomery.org/forums/showflat.php/Number/1303334#Post1303334

I thought this would add more FAE sending more air into the tub and out the PVC holes, and raise the RH by having a continuiouse flow of air going up through the pearl. I also was wondering if you guys think the pump idea would work without water by just poking holes in the pump tubeing and running it along the bottom of the tub and not even use bubble wands? I was thinking this may dry the pearl out though? But im a noob so i have no clue!

Also do you think drilling some more 2 inch holes in the back of the tub stuffed with polyfill will help? If so how many and should i drill them up high or level with the pearl?

Thanks a ton for your time and help guys!:thumbup:

I really dont understand why people waste there time with trying to make fruiting chambers like that work. When a simple shotgun fruiting chamber works.

That first thread you linked is 3 years old. Ive never seen something like that being used.

Get a tub, drill 1/4 inch holes in all sides, top and bottom too, 4-5 inches wet and drained perlite, sit it on shotglass's. Fill with cakes/trays and fluerescent above. 95%+ RH and natural FAE.

That is a horrible fruiting chamber design. But if you built something like that rest assured you can modify those materials to make something that could feasibly work.

I would build a shotty FC but it needs to be out in the open in order to get the proper FAE, thank you for the suggestion though. Iam not willing to just have it sitting out. People are in in out of my house while im at work. I liked this tubs discretness and if i can get the FAE good it should work. Any suggestions if what i said will work? I already have a shotty fc that i will be fruiting some yellow oysters in!

Thanks guys!

Every now and then I get the urge to fruit a small tub so I built a ghetto FC but it works great and it would be easy to modify it to fit your specialized needs.

Get a plastic tub, cut two 1" holes - one on each end around the middle.  Cut one extra 1" hole near the bottom.

If the tub isn't see-through, then flip it upside down and cut a 8x10 or so hole in the bottom and cover it with a piece of clear acrylic ($1.50 at home depot).  Secure it with tape or glue.

Put the lid down upside-down and put a few sheets of wet paper towel down.  Put your tray, or whatever it is you want to fruit on this and case it lightly - just enough to cover it. 

Make sure it gets proper light through the viewport. I have a desklamp with a 6500k cfl that I just set on top of it.

2x a day you mist through the 3rd hole without having to open it. Once a week replace the paper towels.

You won't have 99% humidity, but you should easily hold 80% without much work or effort and that's fine for a cased substrate and isn't low enough to dry out your fruits.

Thats a great idea man im def gonna try that with a half pint cake or something sometime. But anyone know if what i suggested earlier could make my stealth tub work?

I would do that but this tub i build can hole 3 decent size trays so id like to see if i can get it working before cutting out the PVC and trying another idea.

have you noticed that there is absolutely nothing raising your humidity level in there other than the moisture evaporating off of your substrate? (a process which with the fans blowing right on your substrate will exponentially increase)

that thing will never work. there are plenty of stealth teks. the simplest: fill an opaque tub with field capacity perlite and fan a couple times a day.

Well it worked for tokey there has got to be a way to make this work!

"have you noticed that there is absolutely nothing raising your humidity level in there other than the moisture evaporating off of your substrate? (a process which with the fans blowing right on your substrate will exponentially increase)"

dont really understand what your saying there i dont have any substrate in my tub unless your refering the pearl. im just testing the tub.

im not worried about it being automated i just thought the fan could give it some FAE while im at work!

Ugh.. blowing dry air into your FC with a computer fan. Just ugh.

Any air entering the FC must be directed to travel through water so it gets saturated with moisture. As in a Shotgun FC, the air travels through the perlite and wicks up moisture, and in the PmP the air is pumped through a layer of water and LECA.

By blowing dry air directly to your FC you will dry your substrate, lower the humidity too much and thus fuck up any potential for anything mushroomy growing in there...

If you want good FAE, build either a shotgun or a PmP and fan + mist it regularly.

If you want a (nearly) fully automated growing chamber, try a martha with a coolmist on timer hooked up. Or a monotub. Other than these designs, you will never escape the mandatory fanning & misting duties.

you dont now, but you will, and when you do, it will dry out because your just blowing dry air onto it.

It's just a really poor design man, i can't really bother to get into the all the details as of why, but rest assured that box would make a better drying chamber than a fruiting chamber. as dead said, try out a PMP. i started with something similar years ago and got great results.

yo yo yo dawg, I use the poor man's pod and it works great for me. I tried it with per lite but the bubbles carried the per lite up and made some awesome yet unneeded volcanoes. I switched to hydroton in my fish tank FC and I have a plastic bin FC that just has water, bubble wands, and a rack for my cakes to sit on. I made a clear top for the fish tank that has 2 little holes in it, I didn't put any holes in the plastic tub and it seems to be doing great (fat fruits G)

Hey dead do you think hooking up a 30 gal air pump hooked to two bubble wands layed across the bottom with just enough spring water to submerge the wands with the fan goin 5 min every 4 hrs will work? Then cover with soaked pearl? Only thing iam worried about in doing this is the water helping contams produce.

Thanks for the suggestions i had no idea that the dry air is bad.:thumbup:

What makes you so sure?  He lost interest in the hobby and moved on to other things shortly after posting that 'tek'.

Air exchange is the number 1 pinning trigger and also the number 1 contaminant prevention measure.  Fans dry out substrates and create eddys where parts of the area get no air at all and others get dried out from the wind.  I've yet to see an 'automated' terrarium that works, and I've been around this hobby for a long time.

You think i could make a sucessful PmP with this tub if i take out pvc pipe but leave the holes stuffed with polyfil? And seal the fan hole up.

Right on RR your right as usual. Just trying to salvage this stupid tub! Plus id like to get a techniqe down with getting good FAE in a enclosed tub without the use of a shotty FC if its even possible.....

I dont see how anyone could lose interest in this hobby! There is so much different things you can do! LC, Spore Isolation, Making prints and syringes, cloning, agar work! Man i can't wait to learn those things! The way these things grow is VERY Fascinating! Your videos got me hooked RR and i know this will be a hobby for life!
