    I cant seem to find an answer.. Suppose you have a pile you just mixed.. How long does the bacteria starts and how long does the heat start to rise assuming the ratio is correct?

    Takes a few days usually, but I have known piles of grass clippings get hot in a few hours, probably down to surface area that the bacteria can feed on.

    I agree with @zigs, it'll take at least a few days to heat up. Grass clippings heat up the quickest. If I don't get the piles raked up within a few hours of being mowed, the edges are grey and black - because they are singed and charred!! :eek: (I always find that amazing, for some reason. I know it will happen, but still... it's impressive!)

    Did you throw a shovelful (or two...) of dirt or old compost in the pile? This is recommended, as it puts the bacteria in there from the start. Then all they have to do is multiply. (y)

    You can also encourage the bacteria by pouring on any stale beer you might have. Or you can also kick-start it a bit by adding molasses. I believe the ratio is 2 ounces to a gallon of water, applied once a month. (I thought I had it bookmarked, but I can't find it.) Hopefully @Chuck will come along to clarify that, but I'm pretty sure my memory is correct. :) If I'm wrong about the ratio, it still can't hurt it! :D

    Helps to wee on it, but not when you've just added stinging nettles :eek::D

    The ratio is correct but anything with a lot of sugar will work in helping it get started quickly. And, keep adding molasses monthly to feed the growing microbes so as to get more and more of them.

    Update, It is now @ 114F and outside ambient tremperate is 67F. I gain 10 degrees after I put more volume and layer it, I shred some thin layer of brown leaves and added lots of green grass clippings. Also added some "pee".. I think my mixture is getting there. I am really hoping to reach 130 to 140F to kill weed seeds and some pathogens.. Thanks for the advise on more grass clippings.

    Edit: I went downstairs and now it is 120F !!! yey!!!!

    Peeing into compost helps the heat.
