Although we feed our worms mostly food scraps, if we need to boost the reproduction rates to meet high demand we give our worms a special food blend. Our special worm chow is great for not only maximizing worm reproduction, but it also increases the size of the worms so that they can be used for bait. If one desires to keep worms for bait or for any reason where composting is not the primary objective, then this is a great solution. Its concentrated property makes keeping worms a breeze. It has a good smell that is kind of sweet and the worms eat it off the top so quick that it does not draw pest into the worm bin. As stated previously it is very concentrated and it is important not to use more than the worms will consume in about 12 hours. Worms Etc Chow is a great feed for science projects. The can be seen on the surface of the bin when sprinkled lightly onto the surface. The worms are soon trained to eat on the surface of the bedding where they can be seen in dim light (light will make them retreat). As the feed is consumed a fine black layer of worm castings is left in its place. To feed: sprinkle a small amount on the worm bed surface. Wait until it is gone before refeeding. That should be about 1-2 days. Comes as a 1 pound bag.
