With the dub tubs I've got going so far (I know you switched) I've been adding only one large turkey roaster worth of substrate which is about 2.5 inches in my 66qt tubs, but I've been wondering if it pays to go twice as deep. Guess there's only one way to find out but I thought I'd ask.... |
i use 64 quart iris tubs. it may vary on sub depth depending on how tight you pack down your turkey tins with subs. i let mine pasteurize really loosely in each turkey tin. probably add a bit more if i run out of room in the tin and there is some leftover sub.
you will hear tons of arguments on sub depth and all that. sandman i think likes 4-5 inches. ive suggested to some to up the spawn ratio and sub depth depending on the situation. but if you pay attention to prior runs. you will start to notice what your perfect sub depth is. mine used to be 2" max. thats only about 1.5 turkey tins full maybe at most. but now ive upped it to 2 turkey tins per bin. with 4 to 5 quarts spawn that make it hit 3-3.5" mark.
you will get ten different answers on sub depth. but personally i feel you don't need a casing. and a 3" at deepest sub depth is perfect. its more efficient. at least in the setup i run. this may vary depending on your setup. in 3" i can get yield higher than some people who do 5" sub depth with 1/2" casings. so i say whats the point of casing and whats the point of using another inch of substrate? make sense?
but it is all relative. strains, temps, environments all play into this factor. sometimes nature just kicks ass, sometimes it doesn't.
