My friend, Iepa. Compost, mulch or luar is obtained by fermentation of organic waste. This fermentation must be carried out by the ingestion of oxygen. In a closed vessel, it suffocates in the absence of oxygen without being able to take air, instead of being fermented. The moat can be carried out anywhere, accumulating organic waste (leaves, herbs, condyles of the kitchen...), occasionally placing some soil or the moat of the previous session. Do not accumulate more than one meter. It needs moisture but it’s not convenient to keep it in a rain; cover it to your liking but without strangling it. Turn the battery once a month for aeration, and once it’s ready for use after about six months, you’ll notice it easily. The ideal is to build a suitable place for these metatx2o. On the ground, in three series of cages with an area of one square meter and a height of 80 centimeters, closed with boards that can be easily removed and placed on one side: filling one, fermenting the other and extracting and using the luar from the third.
