Bulk substrate tub tips/teks?
    #18816824 - 09/08/13 09:20 PM (10 years, 5 months ago)

Ok so I am going to try a bulk grow using high mountain compost. I have been looking around and found the tek in the link below. I have 5 syringes of cubes on the way, one of which is Penis Envy.

My understanding of a bulk grow is this: 1st knock up some jars like you're doing pf tek. 2nd, when jars are fully colonized break them into chunks and place them into the compost. 3rd, let the compost fully colonize. 4th, begin FAE and fruiting conditions.

Does all this sound correct? What do you recommend.

Sounds good, but if you are doing bulk, I highly recommend you use grain as spawn vs crumbled pf cakes it will give you far more inoculation points which in turn will make your bulk colonize faster which lowers contamination rates

^ What he said.
Rye berries are the way to go imo.

Alright, spawn is the material I knock up with mycelium from what I am understanding. I'll look into the grain option. I'm going to order the compost today.

Oh and btw you can use wbs or rye berries as spawn. They both work very well. WBS is a little easier to get for a lot of us. There is a tek for preping it in the link I provided

Thanks for the link, I was actually just looking at some of franks monotub writeups.

So from what I understand the whole point of spawning to a tub is to get a little mycelium growth turn into a lot more, making for a bulk grow when compared to pf tek jars.

Does the depth of my substrate matter? I would want to use the least amount of substrate per tub so I can conserve compost for future grows.

Most of us use the 66 quart sterilite all clear tubs with latching lid. 3 inches of substrate is the preferred amount. That is about 10 quarts of substrate and 5 to 7 quarts of spawn for the 66 quart tub

Once I have the substrate fully colonized do I treat it like a SGFC and spray/fan it everyday?

I just read that whole thread top to bottom. Im using WBS and the monotub instructions he explains. I will probably do smaller tubs (higher quantity) though, I want more than one chance to do it the right way.

I found a mini monotub tek but the author uses lots of small holes instead of 6 larger holes. Im gonna try to do Franks tek just on smaller tubs, hopefully it works well. I'll post up my results/questions as I get them.

I think it will work just fine. Follow the teks and you'll do fine. I look forward to seeing your progress. Keep us updated. Good luck bud!

31 & 33 quart tubs work really well, too.  Not shoebox-size mini, but a smaller version which provides massive success while also increasing containment of possible contaminations.

This is the current experiment which has provided success.
  • 3 quarts rye grain spawn
  • 6.5 quarts of bulk mix


Bulk Mix:
  • 1 brick coir
  • 2 quarts vermiculite (not the teeny-tiny, finely chopped vermiculite)
  • 1 quart gypsum
  • 2 tblspn Bone Meal w/ 4-12-0
  • 4 tblspn Crushed Oyster Shell
  • 1 Gallon + 1.75 cups distilled water (ph adjusted to 6.8)

You definitely do not need a full quart of gypsum, that is a ridiculous amount.

Yes, I agree. That is absurd.

Disregard the recommendations for 10% dry weight in gypsum.  Disregard all of the percentages for gypsum.

Use a big handful for every brick of coir.

Also, the rest of those additives won't do much IME and distilled water lacks nutrients that tap water provides.

You are definitely reading outdated info. Check out my signature for up-to-date teks for bulk :wink:

:goodluck:

Thanks, Frank.
I've been experimenting.

And I had no idea that the 10% gypsum was old, outdated info.

I mix about 100 pounds of substrate in my concrete mixer per batch.  1 to 1 1/2 cups of gypsum is plenty for that amount.  I used to recommend 10%, but after more experiments I found you can reduce the amount considerably without a reduction in performance. I now use about 1% to 2% by weight.  10% still works well for casing layers, but most members here don't case bulk substrates these days.

RR himself has actually talked recently about how he uses less and less gypsum with no loss of performance.

He said recently a small handful for the brick of coir should be plenty.

Hey Frank if you don't mind a noobie asking..
What benefits does the gypsum give the mushys?

It is minor nutrient source and acts as a pH buffer.

When the mycelium is digesting your substrate, it naturally swings towards the acid side (which favors molds).

Gypsum helps prevent/delay these swings.

When you add gypsum to your grains, it prevents clumping and also acts a pH buffer, though the latter is not really necessary for grains.
