15% spawn ratio in bulk
    #3439914 - 12/02/04 11:12 PM (12 years, 7 months ago)

Do you think I'd be asking for contam trouble if I only mixed 15% or so spawn, or just slower colonization times?

10% Min. 25% is primo

So 15% wouldn't be too risky?

It will work fine - if all else is optimal.

Well I'm spawning to the bottom of a 33 gal tub so I'm not really going to be able to incubate it, I was just going to cover with plastic and let it go. Does it still sound all right?

Should be. You can incubate whole tub. All it takes is time, darkness & optimal temp. Have you followed this THREAD

I use 10% just fine when I've done it.

Commercial growers of agaricus use as little as 1% spawn rate.

Do it like this:

Measure the square footage of your rubbermaid.
Say its 21" x 14". You want your substrate 6" deep.
Convert that to cm. 1 inch = 2.54 centimeters.
Multiply those conversion together and you're left with a cubic centimeters value.
1 Liter = 1000 cc, so divide that answer by 1000, you have the liters required to fill the bottom 6"
1 gallon = 3.79 liters , so divide that by 3.79 and you have the
number of gallons that you need.
4 Quarts = 1 gallon, so multiply that by 4 and you have the number of quarts required to fill the bottom of your tub with 6" of substrate.
Multiple that number of quarts by .25 to find out how much spawn you'll need to have a 25% spawn to bulk ratio.
Subtract that amount from the total substrate and use that much bulk.

confusing. Was never good at math. gotta be a easier way to figure out whats a good quart amount of spawn to use. Probably going to fill 3 large turkey bags of straw to pastuarize. any other guidelines.?

Whoa whoa, it's like 4 little things, your computer comes with a calculator. Go measure the square footage of the bottom of your tub and I will tell you.

Is that with Pastuerized subsrate or sterilized?  I'm sure that's with optimal temps and extremely clean conditions. 

If everything's sterile, the ratio only matters for quickness & even then isn't so important if the number of innoc points is high enough despite the low ratio.

I'm sure this isn't new to you Anno, just something for the other readers to think about.  :smile:

Yep, thank ya much. I'm gonna be extra careful not to allow my temps to exceed 170 deg F during the pastuerization.

As far as I know they (commercial edible growers) use compost which isnt sterile. Al they do is pasteurize. Compost pastuerises itself naturally, it develops heat inside the compoststack up to 170F.

After each grow the growstables are probably sterilesed, but the substrate is not. They DO use a lot of poison though to fight enemies of the mushrooms.. :frown:

Say its 21" x 14". You want your substrate 6" deep.

***21x14= 294

Convert that to cm. 1 inch = 2.54 centimeters.

***294x2.54=746.76

Multiply those conversion together and you're left with a cubic centimeters value.

***Do you mean multiply the 294 x 746.76? Or is 746.76 the cubic cent. value?
