IMO 3 Substrate

IMO3 is 50/50 carbon and carbs of any sort IE: drake has done wood chips (carbon) and dog food (carbs) go to your local feed store see what u can get thats cheep rolled/crimped oats, mill run, char, wood chips whatever u can get that meets the 50/50 mix  

Thank you dagoofman, but cannot use plain Rice cooked or uncooked for the carbohydrate substrate as , no oats, mill run available.

u would chop small mix with carbon and i mean small the more surface area u can get the better could even run them through a grater if u had one and had the time or a food processor to get it small what ever u can .....my question to this would be par cooked or not i would think par cooked it would release more starches n sugars to be available for the IMOs and soften the flesh a bit but maybe it would be unneeded (wouldn't hurt to do a lil test there see whats better) ...i would think the real key here to using these as carbs is the size the smaller the better u would not want large chunks that can just rot in the IMOs but more like shredded so theres not only more availability of the starches n sugars to the microbes but also a less likely to rot situation IMO3 should not be "wet" a lil damp not dry cause water is life and tubers have a lot of water in them so does the plantain so that would be the thing i would take into consideration the most is controlling the moisture when using these as carb source

dagoofman, after some research I found these are available abundantly here, free and high in carbohydrate; 100g of Casava - carbs 95g 100g of Yam - carbs 93g, and 100g of plantain or cooking banana 91g. So how would I go about using them as the substrate?
