If you are starting a new worm bin it is recommended that either you let it age to create a population of beneficial microbes or that an inoculant/starter is used. You will get a bag containing the material directly form one of our bins. We pull the starter from a bed that has just been harvested and setup to start a new cycle. The bag of inoculant will have some small worms in it and a fair number of worm eggs. It will also contain a thriving population of beneficial microbes necessary to healthy composting. Although it would take some time to get the population of worms up, you could start a worm bin using only the inoculant without ever buying a bag of worms. This is not recomended though as it would take 90 or so days for the worms in the inoculant to start reproducing. To use this product: Place half or so of the bag in the bottom of your new bin. Take the other half and mix it with your bedding material, such as shredded news paper, leaves, cardboard or whatever you use. Then your bin is ready for worms and then food. This product helps eliminates many of the problems that new worm keepers face.
