Bulk substrate yields vs. those of grain
    #3311993 -

I have a 33 gal tub. Done most efficiently either way, how much greater of a yield would the bulk substrate produce?

How do you mean allot better? The contrary is the case!

If you have the same weight of colonized grain and the same weight of colonized bulk substrate(straw, dung or compost) the colonized grain will yield more, no question about that.

Now, it is easier and cheaper to prepare large amounts of pasteurized straw than large amounts of sterilized grain. That's where the attractivity of the bulk substrates stems from.

IME this isn't the case at all. It seems about the same if you give it half the amount of grain as you do straw. Personally its easier for me to bring a bag of grain up my apartment then bails of straw or poo, easier to hide while in the apartment as well. Straws great and all..just no more in the apartment. Heres some rye pics:



Note my black bins are 40qt.

Some straw:



This was a quarter pound exactly fresh:

The big one was 40 grams

The substrate was about 2 inches thick on the rye and 4-5 inches thick on the straw. Yeilds per flush were similar but rye lasted for 5 flushes yeilding well..first 3 were excellent. Straw putters out quicker. I cant vouche about when adding poo though..havn't tried that yet.

ok i forgot to think when i read the question, the problem is getting this much grain! i know if i had enough grain to fill a 33 gallon 3" deep ofcourse i would do it, but if you spawned that to say 4-5 straw tubs the yield would be bigger??

Of course if you use 4-5 times more straw than grain you will get bigger yeilds. I but rye in 25 pund bags for 11 bucks a piece. I dont think thats too bad of a price, i have also seen people getting it for much cheaper, but the stuff i get is certified organic so i guess it costs a little more. What they're saying is that pund for poung grain is a better substrate, for a cubensis at least.

yup, apprentice hit it right on the nail. mass vs mass, grain blows bulk out. But of course if you spawn grain into much more bulk substrate you will yield more.

where can you get such grain at said price???

also do you only need to layer it 2" deep in a rubbermaid tub?

I get rye berries for 27 bucks, 50 pound bags from a local health store. You have to ask them to special order it most times though. Other grains are cheaper but from what I hear tend to make worse substrates by themselves but work great for spawn.
