How to Grow Mushrooms: Dub Tub Method

This method to grow mushrooms is one of my long time favorites because it was my first bulk method after learning BRF cakes. I used to use a cheese shredder to shred 4 BRF cakes until i learned how to use quart of rye grain spawn and it worked every time.
In this video i could have gotten a bigger harvest if i would have used a sawdust substrate like Agrocybe aegerita prefers but as you can see they still tolerate the coco coir.

I noticed that the substrate was only pasteurized. Will this work with hardwood pellets and bran? Or how would the dubtub method work with a hardwood substrate? (or does it as most hardwood substrates require sterlization?) And btw loved the straight to the chase vids! Subbed!

[@SporenSprout]

Yes it would work but If you use bran it will have to be sterilized in a pressure cooker first and then dumped into the tub and mixed with grain spawn.

[@wilkiedilkie]

Make sure you also take into account how much fresh air exchange the species needs, if it is something with higher fae requirements you might want to add holes to the top container or otherwise think about increasing airflow

[@DasChristoff]

@@wilkiedilkieagree 100%. In fact most tek methods don’t have enough fae which equals subpar results. I always try to replicate Mother Nature conditions for mushrooms as well as cannabis. Think about it: mushrooms grow outdoors, not confined in a box indoors. I create those same conditions regardless of the tek. High humidity, fresh O2 and temps similar to Mother Nature ie: high 70s day low 70s night. Led lighting on timers for day. Room humidity between 65-80%. Not everyone has a dedicated room for this but if you can you are in full control of the ambient environment. Even doing cakes in sgfc have huge yields when done in these rooms. No matter what tek you do, always try to mimic the outdoor environment and maintaining those conditions. 😉

[@SporenSprout]

Just add some water to the bin after harvesting. Dump the excesss water out after 1-2 hours of soakin. Super easy

[@astbrnrd]

@@SporenSprout so "field capacity" is not the same after harvest? That's the part that stumbled me a bit, but i guess it makes sense, it's already fully colonized. But it was worth the ask 😊👍

[@user-yq8he1hu6m]

Lots of good information, thank you!

[@MissBlackMetal]

​@@astbrnrd I'm a beginner too, but thinking about it, I'd presume that field capacity wouldn't be the same after the mycelium has started fruiting, and especially after harvesting. Mushrooms are 90% water, so if you've just harvested a bunch of mushrooms, that means the water that *was* in your substrate is now inside all those mushrooms. So if you want more mushrooms (i.e., another flush/harvest), you'll need to introduce much more water back into the substrate (i.e., rehydrate it by dunking/soaking). I hope this makes sense! 😊

[@denislavgeorgiev4839]

Can i grow white button mushrooms this way, because they need around 90% humidity of what i heard, and at the fruiting stage the second lit is only resting on the other which results in less humidity if im not wrong. What can i do to keep it more humid, so i can grow them? Also thanks for the great and detailed video 😊

[@SporenSprout]

Yes it would work but white button mushrooms require specialized compost substrate and a casing layer to successfully fruit. As long as you use the correct substrate it would work.

[@Mechaneer]

Love how clear and detailed this was. However, I'm wondering about the specifics of what you meant at the very end when you said "after harvest you can dunk the substrate for 4 hours and get a second flush." Do you or can you talk more specifically about this in another one of your videos?

[@SporenSprout]

I wonder why I get that question all the time! It’s very easy just add some water to the tub and let it soak and then dump out the excess and fruit again. Or remove the substrate cake and soak it and then place it back in the bin.

[@ThiagoPereira-lu3ht]

It is fabulous how from a spore syringe and using the dubtub method you got a full canopy!!

It would possibly work but you have to have a freshly bred strain of black morel and I believe composted substrate is best. It may be a good idea to add viable rye grass seeds to the final substrate and allow grass to grow in the tub as well.

hey man this vid was awesome! I'm getting ready to run some pure coir shoeboxes with brf cakes as spawn. Do you think adding a casing layer at 100 percent colonization or at 0 percent would be beneficial at all? I have around 2 quarts of spawn and the bricks i have make about 5 quarts of substrate. could i put the rest i dont mix on top as a casing? thanks!

[@SporenSprout]

[@helix-phase]

Holy cow, thank you. How relaxed are you with sterilization conditions? I am trying to find the lower bound for sterilization to maximize laziness

[@SporenSprout]

If you use pop corn as a grain spawn you won’t even need a pressure cooker. Just steam bath the jars of corn for 2 hours. The substrate is just pasteurized in the bucket with hot water and adding the spawn doesn’t need to be in front of a flow hood. So it is a very easy relaxed method!

[@hotpotcoconut6994]

Great video, I have a question. If the tub is completely closed while the mycelium colonises the substrate how does the mycelium breathe if there is no air flowing into the box? And with the other tub on top of the colonised substrate how does it breathe also?

[@SporenSprout]

The lid is not a tight seal even when clicked into place. It is fine how it is for 6-10 days during colonization. You can add a couple holes to the lid and cover with tape and that’s fine too. The top tub is removed 3-5 times daily to fan and mist to replace the air and it works fine. You can add holes to the top bin if you want as well.

[@SporenSprout]

You don’t need any grow tents or special environment, the tub provides the environment and you provide fresh air by fanning it 3-5 times per day and replenishing moisture on the top of the bin. Yes 1-2 LED strips in the basement is perfect.

​@@tedkravos7129 the reasons I've heard for not spraying the mushrooms (or mycelium) directly are 1) because they are fragile and even the water droplets can bruise them, and 2) I think it was something about mushrooms will soak up water really fast, and too much water directly on them can increase contamination risk? This one I'm not sure about. I think I heard that 1) is less of an issue if you use an ultra-fine mister. Don't quote me on 2) though cuz I'm really hazy on that one.

Yeah carefully take it out of the liner and submerge it. You have to be very careful not to break the cake. You could even just pour water into the bin and then let it sit for a few hours to absorb and then tilt it to dump out excess

What are the weights of coco peat and vermiculite?

[@jeffreysousa1104]

instead of using the clear bin and lining it with black garbage bag could we just use a coloured bin but still with the clear lid ?

[@SporenSprout]

That would probably work

[@levilinney8364]

Does the jar need light during the inoculation phase???

[@SporenSprout]

No it doesn’t matter

[@nicolecatanzaro4008]

What happens or causes your substrate to not go full white?

[@KLCeup]

I have a question if you don’t mind? I saw that you used brf cakes in the past to do this method. How successful was it? I currently cannot add off a pressure cooker and read that brf cakes can be sterilised in the jars just by boiling. Also, would it be possible to use straw pellets instead of coir? Thank you, awesome vid as usual!

[@SporenSprout]

Yes it was very successful! The BRF jars can be sterilized in a hot water bath for 2.5 hours in a large pot. Here is a video I made about how to make the BRF jars: kzbin.info/www/bejne/qpu2oZJvh9-Ld5I Yes It should work with straw pellets!

@@SporenSprout thank you for your reply and help ❤️

You can also use the Uncle Ben tek which involves no pressure cooker at all.

[@lucydog3376]

@@KLCeup Yes as another commenter stated Uncle bens tek requires no pressure cooker and not very much work at all. It's basically a cheat code where all the hard work is already done when it comes to preparing spawn. another tek that works very well without a pressure cooker, but still involves a bit of work is popcorn tek. Using store bought popcorn kernels as your initial grain is great because since they are sold for human consumption they are already quite clean and free of mold spores and bacteria out of the bag. Sterilizing them with steam is still required to be sure, but just a big pot on the stove will do the trick, pressure cookers are unnecessary for popcorn tek. I find popcorn tek to be better than unlce bens results wise and better than BRF in that the preparation isn't so messy.

[@KLCeup]

@@lucydog3376 that’s all very helpful thank you!

[@mauntak404]

Is vermiculite required to grow the mushrooms or could I use only coco coir as my substrate?

[@SporenSprout]

You can just use coco coir.
