So, I was intrigued by the mention of using alfalfa cubes to provide a fermented green. I purchased a 50lb bag from my feed store and embarked on an experiment. Not having any reference as to how much to try, I added a large double handful of the cubes to my 5g FF bucket. 24 hours later, and I have made a few observations.
1: Never, ever, EVER underestimate the water absorbtion capabilities of dehydrated grass, lol. I have been adding water a few glugs at a time every couple of hour since. It's still drinking, lol.
2: Never, ever, EVER underestimate just how much volume that alfalfa hay loses as it is dehydrated and is compacted into cubes, lol. I now have a 5g bucket FULL of FF and am eyballing the empty bucket next to it wondering if I will need to expand my oporations.
3: Adding massive infusions of food into the brew all at once tends to dramatically slow the firmentation process, aparently you CAN choke a bacteria by shoving food down it's throat, lol.
4: It's popular. Even with the firmentation just now catching up with the influx of food, my chickens are tearing into it.
5: It smells SO much better, so far. I love the smell of that alfala, dry and in the bag, or in the bucket. I may change my mind as the firment catches back up and I fine tune the right amount of cubes to add at a time, but for now; mmmmmmmmm....hay.
