Best bulk substrate mix for shoebox tub?
    #26334017 - 11/20/19 05:08 PM (4 years, 2 months ago)

Hello to all, I only have one quart of grain spawn I can use, so I believe my best option is going to be one of those mini 7 quart shoebox tubs. I am planning on making my substrate from coco coir, vermiculite, and gypsum and just bought them all today. What is the best amount of each ingredient I should use that will make the optimal bulk substrate for something this size? Also remember I only have one quart of grain spawn, that's why I believe using a 7 quart shoebox tub is the best thing for me. I can't find any substrate Teks for a tub of this size, I have only found amounts for the big tubs. What do you guys do or recommend that you've been successful with? I'm looking to achieve a very dense flush with lots of mushies.

Yeah I’d do a 1-1 maybe 1-1.5 ratio. So about a quart and a half of coir. I think that’s like a quarter brick maybe little less.

Also after mixing it all up putting another 1/4 inch or so layer of coir on top seems to help a lot.

Just use the same ratio as the bigger teks use, so if you have 1qt of spawn mix that with 1qt of sub. That will leave that container 2/7ths the way full, probably should be good. Not speaking from experience, just regurgitating all the information I've been reading.

:whathesaid: I would do the same. probably closer to 1:1.5 tho with top layer

Just keep in mind if the substrate is too thin it will dry out hella quick.

So no vermiculite at all or gypsum at all? Why only coir? What’s the reasoning?

So no vermiculite at all? Just only coir? Why is this? What’s the reasoning? I thought vermiculite and gypsum is a basic standard in substrates.

Using coir only is just easier. You can add verm and gypsum if you want. I don’t think it’s ever been shown to be a huge difference tho...might as well use it man, you already bought it!

Can throw a tablespoon of gypsum in your mix it won't hurt

It doesn't matter what i think of you...all that matters is clean spawn

I've searched high and low for the secret super bulk recipe and its coir, just coir and verm. Unless you want to use poo, poo is magical for some.
