XL Monotub Grow Experiment! 1
#22279363 - 09/23/15 03:36 PM (8 years, 4 months ago) |

So I've always been a little curious about how a really big monotub would perform compared to a normal sized one. So I bit the bullet, bought a 105 qt sterilite tub from walmart, and picked out my 13 best looking quart jars of spawn.

I decided to buy a different type of coir called "Black Gold." It seems like decent quality, and I don't have to chip away at those 5kg compressed bricks which makes things a lot easier. Normally, I used 650g of coir, 2 quarts of dry coarse vermiculite, and 1/2 quart of pelletized gypsum. For this XL mono, I used double that quantity, which comes out to roughly 20-24 quarts of bulk substrate when fully hydrated. I pasteurized on the stove as normal for 90 minutes at 140-170 degrees.

I drilled six 1.5" holes at substrate level and four 2" holes up high to ensure adequate FAE. Initially, I was concerned that my roughly 35 quarts of spawn and bulk would end up being too deep, but the substrate depth came out to exactly 3.5".
I'm interested to see the outcome of this, but contamination is definitely a concern. All it takes is one bad jar, and everything'll bust. They say that you should aim for one dry ounce per quart of spawn used on the first flush, but I seriously doubt that will be the case. Once it's done colonizing, I plan on casing before introducing to fruiting conditions. I haven't seen too many other big mono's like this, so feel free to post a link if you know of any. Wish me luck!

Thanks! I was planning on using a 150 qt tub and using 3x the normal amount of spawn and bulk, but I thought that was too much of a spawn investment. Plus, none of the large tubs I could find were clear, and I was just too lazy to modify the lid.

I exclusively use that same 105 tub (many of them!) , with almost the exact same hole size and placement.
My hint is this: the large lid provides too much FAE, during colonization. My solution is to secure the lid with 6 "bulldog" stationary clips. 3 along each long side. I pull them off, when I pull my tape, and polyfil the holes. Find them at a dollar store, for cheap.

Nice, ive been wondering about the yeild difference between big and small tubs if there is a difference.
It would be interesting to build like a 4'x5' box lined in plastic and used like a mono but use fans for big computeer fans for fae.

No, no I don't. I really don't want to have to buy a second dehydrator new, so I've been keeping an eye out on CL and at thrift stores. I got lucky and found the one I currently have at a thrift store for 99 cents.

IME, no more than fanning once a day is really necessary.
Just, if it isn't cased you might want to worry about humidity.
It can't hurt as long as enough moisture is there.
Too much gas exchange though, and you'll exchange the H2O(g) right out of it.
With casing, spraying the sides or misting was enough for me but straw I had to be a bit more careful.

I bet that looks cool, just a huge mushie carpet lol. Ive been wanting to try a straw log for cubes but am worried about contams. Although I just got some oysters and lionsmane so I might try straw with oysters and if I do might as well give it a try with cubes to. Whats your exp with straw like? Worth it? And for a huge mono would that be a good way to go?

When I was down in Mexico 2 years ago a friend and I modified the hoels of a really big but old still air box and used it as a fruiting chamber. This thing was like 4 feet long. I never got pictures of it.
Your experiment will work. The more surface area the better, when it comes to fruiting. It's just important to never make subs too thick, as the extra heat and lack of o2 can cause anaerobic bacteria issues.

TBH, I think that it could work reasonably well in a baby pool as long as the substrate wasn't too deep and you could keep it from drying out. I would case it after colonization, then place it in a tent with an ultrasonic and a fan. You knows, maybe.

A baby pool would be awsome, some day I will try that if I have enough extra materials. I imagine something like course perlite would be necessary to keep it from packing too much. I bet you would get some monsters in the later flushes.

I would guess so too. I think that perlite would be a good thing to add, but it would definitely need to be cased IMO to prevent it from drying out. I honestly think that the best way to do it would be to place it in a large greenhouse with a few humidifiers. Honestly, I as long as it didn't dry out, I don't see why it couldn't work. Someone needs to just try.

Awesome! Good luck! I don't have much experience with big tubs, but I'd guess that moving it after colonization would likely crack it. The weight would probably pull down the structure and put too much pressure on the sub. Just a heads up!

Guys, I'm sorry. It's done. All of the spawn jars I used looked and smelled clean, but there must have been something hiding in there. What should I do? I have four spawn bags sitting around, and I was thinking about using two of them and giving this another shot. I really want to get this one right. This whole thing feels so unsatisfying.

Put some plywood under the tub to carry it by like an earlier posters said! Go thin on your sub depth too. Good luck!

Alright! I decided to try this one more time. I used two spawn bags, each with about 8 quarts of spawn. Hopefully it goes better this time around. I'll post an update when it's either colonized or contaminated.

I've been having great results with the 105 Sterilite. I'm down from a 4"sub to 3", and loving the results. A typical mono has the following ingredients:
Shredded straw - 380g dry Coir - 450g dry Verm - 2 quarts Gypsum - probably 1/2 cup Dry kelp - 30 ml (added to coir buckets) Rye spawn - 7 very full jars (probably 6 full quarts)
Cased at full consolidation (15-18 days) , with coir/verm 3/16". FAE at 40-60 %, no patching.
I make 6 of these at a time, every 7-10 days...

Hey guys! Just wanted to give an update. Everything is looking good, and I cased yesterday with a layer of pasteurized jiffy mix. I closed it back up, so hopefully I won't see any signs of contams before I patch.
I'll post another update with a few pics once it's patched and in fruiting. I just didn't feel like a picture was warranted here.

Looking good! The casing layer was patched today and fruiting conditions were introduced. I'm not trying to get my hopes up too high, but if contaminants have not showed presented themselves by now, there is a good chance we can make it to harvest. In my experience, most tubs that become contaminated fall prey to mold during colonization. Fingers crossed!

Okay, so this was basically a success, but with a caveat. Before the tub started pinning, I noticed the dreaded trichoderma. Since I didn't have any other projects going on, I felt that it was appropriate to cut out the small area of mold, give it a wide berth, and hope for the best. What was most surprising was that the mold never came back, even after the tub finished. I have never seen that happen before. Usually, removing a moldy area only buys you a few days, but there was no mold in or around the area that was removed.
In total, she yielded 317.7 grams cracker dry, which is by far the most I have ever pulled off of a single mono. That is significantly below one ounce per quart of spawn, but considering the fact that it got contaminated, I am very lucky to have harvested anything at all. Regardless, I tossed the sub once everything was harvested just in case. Thanks for following this thread, and if you have any questions, feel free to ask them below.

Two spawn bags, so roughly 16 quarts jars worth. Quite a lot.
