How To Protect From Contams When Spawning to With MiniMono/Shotgun Hybrid For Small Bulk Grow?
    #26854841 - 07/31/20 03:33 AM (3 years, 6 months ago)

Hello there.

I have searched and not found much info on this that explains the best method.

I plan to do a small bulk grow for the first time with maybe two small tubs using the hybrid SGFC/MiniMono design. It’s basically a mini mono tub but uses shotgun fruit chamber type hole patterns. I like the design since they can be smaller, may require less tending, and I have had good luck with SGFC in the past in my environment.

I plan on using coir/verm substrate using the updated double bucket and blanket tek, spawning with popcorn, and using Penis Envy multispore.

I have seen a few teks on this method, however I have seen that most farmers simply put the tub after spawning into a black trash bag and putting it on the shelf.

*Since I will not be using a mono tub with poly fill filters in it during colonization, is it safe to use just a trash bag with no modification? *

The teks show that the tub is left with all holes open to allow for gas exchange. But, there seems to be no consensus on weather or not to tie off the bag, leave it loose, or tie it off and open it up every couple of days to allow GE.

I would think, if the bag were tied off, there would not be sufficient GE for full colonization. Unless the idea is that the mini mono/SGFC has such a small amount of substrate to colonize, that there is enough room in the bag to allow GE for the full 10 days or more needed to complete colonization.

I would think, If the bag was loose, you could get contamination from the open air holes in the tub that aren’t filtered. And similarly, if you open the bag after a few days, you would also run a risk.

If you open the bag at all, I have not seen anything regarding how long to keep the bag open, or if you can the bag just enough to allow GE but not encourage air exchange we don’t want during colonization.

Again I have searched and other farmers don’t seem concerned with this part at all really. I am however. It’s my first bulk and I will be using the rest of my corn. I’d rather not have to order another print since I won’t have fruit to print from this grow.

Since I have written a thread, on a separate note, how small can you actually go with this design? I know it will scale up well, but haven’t heard if the reverse is true.

Also, I’ve been using a SAB for my sterile technique, but I am sadly too large of a human to fit in a sterilite bin. So I have a small closet with no AC return that is inside an empty small room in my home. But the closet door has slats in it and slides closed as well.

Is this a bad choice of a room for the spawning process? Should I put a tarp over the door frame to make a small semi sterile room? I’d rather not use my bathroom because - reasons.

Thanks for reading, hopefully will have some fruit here soon. Jars are looking strong so far!

Out of interest, if you are looking for a more compact set up then why just do a straight up shoebox? The idea is that the lid on the shoebox doesn't seal completely so there is enough movement of air for GE/FAE so no need to go drilling holes in stuff. Just spawn, shut the lid, and wait. You might need to mist now and then but if your sub is proper field capacity then it should take care of itself.

Regarding contam and bulk, iirc, your spawn should be very contam resistant once it's fully colonized and beyond that pasteurizing you bulk sub gives the myc enough of a head start to out compete any contam. What really matters is that your spawn is clean and healthy and you sub is properly pasteurized. And try to not open the lid every 5 mins!

I'd do a monotub if you only do one there not really that big. And for being a big human you know only your arms have to fit in a sab.just cut bigger arm holes

Coversall. You know that is a thought. I'll look into shoe boxes. That's a size I could maybe do. As of today, my corn jars are way out of sync with each other. I'm trying to keep the faster jars growing slower to match the other jars by not shaking them until the other jars catch up. So, I may have to go even smaller in size container than I though originally if I can't get them all to finish colonizing at about the same time.

Mycobro420, I was joking with the idea that I could fit inside my SAB and use it as a clean room for during the spawning process. Hahah. Plenty of room for my arms. I haven't ever used a monotub, or done any bulk grows yet. But I have read a lot about people struggling with "tuning" the monotubs with hole size and polyfill amount and tightness. I'd rather not have to deal with that, and I have always loved the idea of shotguns, they seem to provide me with max fresh air exchange very well, so I was playing with idea of this hybrid design. What's your thoughts on having to fiddle around with monotubs?

If I remember right, quite a few experienced growers now introduce fresh air (initiate fruiting) at the time that they mix their spawn with their sub. Aka they’ll mix their colonized grains with their coir/Verm in the mono/shoebox/whatever fruiting chamber they use, and not bother letting the sub colonize or consolidate. As long as your spawn is clean, you shouldn’t have to worry about contams at that point.

I second the idea of using a mono/shoebox. I have no experience with a sgfc but it seems tedious to create the thing. I just use a tote in between shoebox and mono size, cut 2 holes, and cover with tape if I feel like things are drying out too quickly. If it’s too wet, I remove the tape and/or lid and let it dry a bit.

Also, yeah keep the grow away from the bathroom, no matter what stage you’re at lol. Take all this with a grain of salt, I’m a noob myself. Good luck buddy 👍

No need to put the tub in a bag that is old news, light is good for mycelium at all stages. In your case a shoebox is your best option, as others have said introducing to fruiting conditions right after spawn is becoming more and more popular. Just have to get your surface conditions on point

GayFish:
Thanks for your kind words! Very interesting idea to not wait for colonization and go straight to fruiting. So the idea is that the popcorn should be strong enough that contamination is not an issue with open air holes in your fruiting chamber? I can see how light and air would encourage fruiting no matter what stage the bulk substrate is in. I do wonder though, for good pinsets, people typically mention that NO FAE is what you want during colonization and pin set, but that you only want gas exchange. The lack of light from using a trash back, I don't like. I've had awesome results with my brf cakes having them near a window during colonization. But I have been pin setting with wax paper cups over the cakes. - If I were to go straight to fruiting with uncolonized bulk coir/verm, do you think there would be a lack of pin sets or more with it trying to fruit and colonize at the same time? I thought that you want to colonize completely to have more cake area that will fruit for best results? In any case, I'm going to dig up on not waiting for colonization.

TheGreatGig:
Thanks for your input as well! I seem to have missed the news about the bags haha. Every time I search, or read a tek, they all seem to be very old. Though I do dig through the thread to find any updates or outcomes to the methods that may have been added.

No problem man the search function takes some getting used to.
Here is a link to a great shoebox tek that I think will give you all the info you need

Haha. Right on brother. I was just reading that exact link. I like it. A LOT. It meets my needs for size. And I can throw out drilling and liners. And I like they can be stacked. Also, until I can get some prints or have time to do many G2G's to get my jar count up, I will have to be using small amounts of substrate. I think I'm going to go this route. Can't argue with those results! I would probably fruit with a lid, and go dub if I needed space for the canopy. Super digging this. Seems so simple, you almost don't want to believe it.

Yea man it's crazy how simple cultivation becomes once you nail down getting clean spawn. After that it's just letting nature take its course with proper surface conditions that is
