Air Ducts

One pair of Air Ducts

AIR DUCTS are designed to aid air circulation to the base of the compost bin. They  protrude out of the front and back of the compost bin. When in use material sits directly on top of them and where the material is in contact with the soil to the side, worms and micro-organisms in the soil can work their way up into the mix. An added benefit can be gained by raising the Compost System up on a brick so that air gets to the base of the mix around the perimeter

                                                                                                                                                                                 

E.g. a double Compost System, 6ft. (1.8m) x 3ft. (0.9m) x 3ft. (0.9m) has two bins and requires two sets of Air Ducts. There are two strips per set. However,they cannot be used with aerating-Bases.

Slatted vs Close Boarded Compost Bins

We offer either Slatted or Close Boarded Compost Bins. Professional opinion varies though we usually advise that the contents in the Close Boarded Compost Bin will reach a higher temperature and thus kill more weed seeds, diseased material and decompose slightly quicker than other Compost Bins. The disadvantage may be that wet soggy material may stay wet and soggy and not decompose efficiently at the base where there is little or no air. We suggest the use of Air Ducts or aerating-Bases to encourage air to the base.

How do I make good Compost in a Compost Bin?

We suggest filling the Compost System by making the heap inside the bin with a mixture of nitrogen-rich material (such as grass clippings, vegetable peelings) and carbon-rich material (such as bark, fibrous material or shredded paper); a good ratio is 1:2. At the base place a layer of twiggy material; ideally build up the heap in 15cm (6″) layers, if possible avoid too much grass clippings or leaves, as air movement is inhibited. Clippings from prunings may be used, although it is advisable to shred woody stems first. Compost only young weeds; weeds with seed, or those about to set seed, should preferably be burned, as should all pernicious and perennial weeds.
