Keep posting your progress, Tom. Really enjoying this thread.
This doesn’t seem more complex than PF. Think you could have done this first?

Re: First time grow with spawn bags and bulk substrate. [Re: KindOne]
    #26166654 -

Hi Guys,

It been 32 days since I shook the bags.  Bag #1 is about 90% colonized, with only the top surface still colonizing.  Bag #2 is about 85% colonized, with a sliver of one side and the top surface still colonizing.

The colonization seems to have slowed, despite maintaining an ambient temperature of around 71 degrees overnight and about 75-76 degrees during the day.

My primary concern now is what to do if bag #1 finishes colonizing and bag #2 isn’t finished.  If bag #2 doesn’t finish with a few days of bag #1, I’m considering discarding the uncolonized portion of bag #2 and mixing it into the substrate with bag #1. 

Does that sound like a safe approach?

KindOne,

This process is much more complex and takes a lot longer than PF tek.  I’m glad I “learned the hyphal ropes” with PF tek first.  I don’t recommend anyone diving into grain bag colonization without first having success with PF tek.

Not sure what I would do. I would most likely let them both finish if they finished within a week or so of one another. If not then I may do what you are saying. Either way you should be fine.

My pleasure. I look forward to hearing the results, and I hope you have some very productive research.

Man, I can't get my current tub to stop growing lol. I am on the seventh flush. I have a new bag ready to go, but I can only grow one tub at a time to keep it stealth.

That's great!  Being unable to stop a tub from growing is a very good problem to have.  Congratulations.

Yeah, I guess if I am going to have a "problem" that is a good one to have. The seventh flush only has about ten fruits. They look healthy so I'll let them finish up this week and then bury the substrate somewhere in the woods.

Oh shit!  Even though bag #2 doesn't appear to be completely colonized, there is a shroom growing in the bottom of the bag! What should I do?  Remove the shroom and immediately mix both spawn bags with the substrate in the tub?  Please advise ASAP.

Thanks,

Tom

With fruit growing in both bags, I couldn't wait to give the grain more time to completely colonize because I feared more fruit would grow and then potentially die, leading to rotting and contamination.  About 90% of the grain was colonized. 

I dumped the spawn into a clean bowl and mixed it well in an effort to at least bring all of the uncolonized grain in contact with colonized grain.  Kind of a late shake.

I removed the fruit and put them in my desiccant box.

I realize that uncolonized grain invites rotting and contamination, but I didn't know what else to do.  Hopefully, my impulsive decision won't ruin the whole tub.

I cleaned my 32 quart tub with alcohol and let it dry.  I mixed the spawn with the substrate and dumped it into the tub.  I put about a half inch of substrate on top to serve as pseudo casing.

I misted the substrate and put on the lid.

I applied micropore tape to the holes per Pastywhyte's instructions.  Two layers on the bottom holes and one layer on the top holes.

Now I wait for the substrate to colonize or possibly turn into a festering bog of mold and bacteria.

I'm twitching and itching with fear

Lol, I'm sure you will be fine man. Normally you want to just discard any grains that do not appear colonized. Being that you put 1/2" substrate on top to mimic casing, I think you will be okay with the uncolonized grain in your mix. I don't put that thick of a top coat on because it slows the colonization process down quite a bit, but in your case that decision may save your ass with the uncolonized grain. I usually sprinkle a little sub over the mix just to cover the exposed seeds a little. I doubt it makes much of a difference, but it will take several more days to colonize with a thick layer of sub on top of the mix. I would give it a good 10 days to get close to complete with 1/2" on top. Being that you had fruits growing in your bag, it may colonize faster.

Your fine man. Getting fruits in jars or bags is no biggy. It shows healthy growth! You have seen pins before you ever spawned to bulk. Congrats!!!

Of course, it may show that you have a little bacteria in the grains, which would keep some from colonizing while the rest is already pining. A little bacteria is absolutely nothing to worry about though. Sounds like your doing a great job.

You make me want to experiment, but I have done too much lately and have to take at least 10 days or so to break my tolerance.

JD,

Thanks again for your reassurance.

This morning, the interior of the tub was coated with condensation, except for dry airways between the top and bottom holes. I'm pleased to see that it's getting good FAE. I see no need to mist it.

Hopefully 10 days from now will be a good day for both of us.

You should not need to mist at all until full colonization and most likely you won't need to until the end of your first flush or during your second. What you are after is tiny water droplets forming on the fresh mycelium. As long as the droplets are there, you are good to go. They may dry up a tad on your last few days of fruiting, but most of the time you have enough water in a monotub for your first flush without misting.

I think two things I learned were the most helpful. One is using sunlight at the right time to get a great pinset. After the tub is mostly colonized, after about 5 to 7 days, you can put the tub by a window for direct sunlight for about 15 minutes each day until you get a ton of pins. The intense light and warmth will increase your pinset. I read that from a very experienced mycologist who went by the name Roger Rabbit. He knew his stuff and is one of the only guys who actually tested his theories in scientific ways.

The second thing is giving it a lot of FAE on the final days of fruiting. After you have pins everywhere you want to start increasing your FAE. Around three days after pins you can really increase it for the last two days of growth. You can usually leave one or two of your top holes completely open the last two days of the first flush, or just put a piece of poly stretched out extremely thin and just barely sitting in the top holes. I only do that just in case a gnat or fly shows up, lol. Of course this could could change if you had low moisture content when you started or a ton of FAE already, but most guys really open them up the last few days of a first flush. In later flushes, I have never had enough moisture to leave holes open like that. I have to cover up some holes with duct tape just to keep humidity in the tub.   

I finally quit my tub after 7 flushes. I buried it yesterday. I plan to mix up a new batch to bulk tonight. I think I only got about 120 or so wet grams off the last flush; it dried to only 10 grams. Better than nothing for sure.

Well I finally made a new tub on 9/18 at around 2am. Here is how it looks at 11pm on 9/19, about 45 hours later. I would normally put a small layer of sub on top, but my sub ended up being too wet, so I added some verm and mixed it up again to get it as close to perfect as possible. After doing that, I did not have any sub left to top coat it. This is probably what your seeds all look like under the top layer.

We’ve been in the tub for 10 days.  Two days ago, I suspended an 18 watt, 6500K CFL 22 inches above the lid of the tub.  I keep it on from 6am to 6 pm. 

Today, mycelium covers about 95% of the surface.  There are a couple of small bare patches, but they are filling in.  There is less condensation on the walls.  The mycelium is covered with tiny water droplets that look like glistening diamonds.  I take that as a good sign.

Now I await pinning.

Just before I left home for work, I checked the tub one last time.  I discovered the first pin!  Whoo-hoo!  I look forward to getting home and seeing what other treasures await.
