But...
why you need to rotate the drum.
How can you separate te worm from the soil???
One of the purposes of this drum is to prepare food for the worms. Food scraps will release heat when decomposing. The worms won't like the heat. Therefore the food is first prepared here and then put into the worm bin. But of course, if you don't have worms, this drum is an effective tool to prepare compost on its own. (rotatable drum is needed for mixing the different ingredients effectively)
How to separate the worms? That will be another story la |
