Monotub didn't colonize.
    #26799921 - 07/02/20 05:36 PM (1 month, 4 days ago)

Hey,

I just checked out my monotub after two weeks. I used a 1:1 ratio rye spawn to coco/verm/used coffee grounds/gypsum. I checked the ph and sterilized myself. This is my 2nd tub and 1st time making my own substrate. 

It appears to be dead. The grain has gone brown and it has a fermented smell.

I kept as clean and I could through the process. This time I taped holes and put the whole tub into a black trash bag. The 1st one I did worked, and I used the tin foil method for that.

Anyone know what might have happened here?

What temperature in the room?

Maybe you didn't get good field capacity re you substrate.
ie moisture level.

If you really sterilized and not pasteurized then it mightve been the problem

I would leave that coffee out, it's a contam vector.
Proper pasteurization is needed for this.
Just do coir to spawn and you're safe.
Trashbag is a bit outdated but shouldn't hurt.

Ya man in one of the threads I expressed my deep trauma with spent coffee... I had tons of tubs go wrong with the addition of spent coffee but thats also becauseI havent really pasteurized properly. This was way before..

Op, stick with PURE coir, or maybe add a bir of verm next time, you might like the results.

Ah I thought you sterilize the substrate/casing and then pasteurize the faux casing layer.

Room has been at 76 degrees. Might have let it slip but a few degrees here and there. I have a small apartment and I had some pf cakes fruiting in the same space.

You sterilize grains and not bulk subs

So it is :elmo:

F.e. if you sterilize your coco, you destroy important warriors in it to resist against some nasties, and molds will have easy game.
Coir is very mold resistant, i bet you even don`t need to pasteurize it, but i do anyway.

By the way, how do you add the gypsum?
I put mine in the grain soak water.

Perhaps you may try coffee later on, when you play the game perfectly

Plain Coir is so resistant you can sterilize it and still colonize properly. Or so Ive heard.

Its the spent coffee that possibly fucked wit your grow.

Man.. after I read the first post, I almost thought it was a troll post since there’s so many things I wouldn’t have done lol. I don’t know why so many ppl think it’s a good idea to seal up their tubs in the colonizing stage, but it’s not... especially in the summer months.  Tubs can survive with some bacterial infection just fine to put out at least a decent first flush, but if your grain was even a little bacterial and you seal up their environment completely (definitely ditch the garbage bag) and create an anaerobic environment, bacteria is going to thrive and you won’t even get to a first flush

76 degrees in the room probably means like low 80’s in your tub... in the summer, that’s too hot... can a tub survive? Sure but try and get that temp down about 5 degrees.

As has been said, absolutely get rid of the coffee.. then you don’t need to worry about ph balancing anything.

Think lazy.. think the least amount of steps possible.  Go straight into fruiting conditions.  Build one of these tubs Pasty’s micro pore tape tubsPasty’s ez dialed tubs  Even with those tub designs, you can easily adjust air flow if you don’t want to fully put into fruiting conditions right away (use an extra layer of micro pore tape or put some MC tape over a few holes in the EZ dialed design, but don’t seal up your tubs) and there’s no reason to restrict light even from the moment you spawn.  Full colonization has been the number one pinning trigger IME.  The only time light might play a role in early pinning is when you use a 1:4 or above spawn to bulk mix ratio.  I’d say use a 1:2 or 1:3 ratio to start.

I’m not sure what the foil tek is but I doubt you need it.. the only thing I’ve needed foil for is for printing, chocolate wrappers and keeping pf cakes off perlite (small circles the diameter of a pf cake.  Myc will also eat through foil. 

Bucket tek coir and verm is so easy and fool proof, no need to add anything else and lots of ppl aren’t even boiling the water anymore—hot tap water works fine.  Keep is super simple. Sucks your tub went south but if you make those adjustments, you’ll have canopies in no time :rasta:

Thanks for all the input!

Haha. There is a load if bad info out there and I am only learning how to use this forum to get the best info. I couldn't even navigate to the teks when I first came on here not long ago. Hence the sealed tub.

The room was not 76 the tub was. Made a mistake typing above So I am all good there.

Coffee will never be used again.

"Think lazy.. think the least amount of steps possible. " Good advice.

Spawn Ratio: I'll bring it down. Can't go too low as that is all I am willing to spend until I am skilled enough. Then I'll buy bulk rye and commit fully to the hobby. Hard enough to come by where I am but I am still looking so I don't have to order with shipping.

The foil thing is something I saw demoed here. I believe it is to keep CO2 levels high. I wont do it next time as I now know there is no real need:
