Coir Monotub

I spawned this tub 12 days ago with 5 quarts popcorn spawn. Decided to check the progress since I haven't opened it up until this point and was surprised to see it was pinning already. So, I took the tape off the holes and filled with loose polyfil to put it in fruiting properly.

The substrate is 1 brick of coco coir from the pet store with 1 quart of verm. The pet store stuff is only like $3 a brick and I think pet stores are a lot more common that hydro stores in most areas so no need to order online if there isn't a hydro store near you. I also hear that the stuff intented for plants is intentionally laced with trichoderma, a nasty mold that is the nemesis to the mushroom cultivator. I imagine it helps roots uptake nutrients or works to help break soil down, I don't know, but you don't want it anywhere near you spawn that's for sure. I pasturized the coir and verm together by putting them both into a 5 gallon bucket and dumping 4 quarts of boiling water in and putting the lid on. Wrapped a blanket around it then to try to keep as much of the heat in as long as possible. Once the whole thing was cool (about 6-8 hours) I mixed it up to break up any chunks and spawned with my 5 quarts of Ecuador popcorn spawn.

The tek I used (more or less) can be found here:
How I do Coir

Only changes I made were only using 1 quart of verm instead of 2, and I also break the coir up by peeling off the layers with a screwdriver. If you've ever worked with coir you know what I mean. It is pressed into layers that you can peel away if you are careful. I feel that allows for more even heat and water absorption.

That's pretty much it. I don't think it gets much simpler than that. I'll continue to post updates when things get more interesting.

Sonar, as for your not wanting to get near trich - it isn't possible, it is one of the most numberous and pervasive molds out of doors (indoors I believe it is penicilium. I have done numbers of tests to see what sort of contams are around using petri dishes open for 1 minute 5 minutes and 20 minutes. I have done swabs from my body and clothing, from dirt outside, from kitchen sponges (very very nasty) and other places. I was going to get to that in my agar thread but it seems as though there is little interest).

Trich can easily be killed by pastureization but the main point always is to keep conditions from getting to the point where the trich takes hold. Moving air, high PH and low humidity are keys. But you know all this, it is just for the others who lurk around here.

Yeah I meant that more figuratively that literally. I should have been more clear. Like you said, the spores are floating around in the air they are impossible to avoid. To me it's always seemed like a race against time. Hope the mycelium is able to take a foothold in the substrate before the contams do.

I'd like to hear more on agar. Mainly when it comes to cloning and the finer points of strain isolation.

Sonar, it is cold here and as you may know I hate paying to heat the house or even a room for just a few dishes, so they are growing rather slowly.

Sonar approx how many quarts do you get from a coir brick when hydrated to field capacity?

Trying to calculate recipe proportions using damion5050s tek for a few extra BRF cakes currently in 1/2 pints. Thx

One brick of coir makes around 8 quarts of expanded substrate.

I know I lost a few posts but I believe I was at 64g with this tub. Plus another 20g plus whatever is in this flush. This is the point in the tub where it starts throwing off some massive fruits. I have 5 more jars of spawn ready to go so I will probably just toss it after this flush.

What will be your mixture for your next tub? Will there be any additions or alterations to your tek?

Looking good. You know the itty bitty ones that never get very big are the most potent. I would save those for 4th of July.

I have some casting and some straw I was thinking about experimenting with, but I think all I am going to do is case. I like to only make one major change at a time to keep some sort of experimental control.

I have 2 jars of pan cambo spawn I plan on using maybe this weekend if I have time. If that works out I think that will be my personal summer stash. ;)
Right now I have so many cubes, I'm going to have to start giving them away or trading soon. I've actually been considering hanging up the guerrilla gear after this year and just running boomers. It's much easier to trade them for my modest smoking needs rather than put all the time and effort into growing. If I didn't enjoy it so much I probably would.

Damn. I know that this isn't the area for it, but I love to grow the green. But the shroom thing is becoming more and more interesting to me. As far as growing is concerned. Lets see how your next one goes.

Well, this is turning out to be a better flush than I thought. Those bigguns from a few days ago are picked and drying, so this is what we are left with. Looking for maybe 4 oz total from this flush, but probably going to be more like 3.

Check out the upside down mushrooms. :grin:

Keep your shit in a cooler box, the insulation keeps the heat generated by the organic chemistry inside, somewhat negating the influence of lower temps outside.

No casing. Going to try it on the next tub though.

I have a little bit more yet that isn't dry, but right now I'm already up over 100g on this flush. I'll try to get some pics and some accurate number up in the morning for anyone still following along.

I'm still not sure what the deal is with these coir tubs. I spawned this tub 2/4 and put it into fruit 2/15. Got an ounce or two off the first flush then just trickled another ounce or two for the next month. Now, over a month since spawning, I get a nice flush. Every coir tub I've done so far has been the same way. I have a few theories, but I don't get it.
