Growing cannabis in compost

This approach is not as purely organic as using compost as part of the cultivation method—although many growers dismiss the difference and choose to go with bottled recipes for valid reasons like simplicity and convenience.

Compost vs. Bottled Soil Amendments

In the natural world, plants and animal matter decays on the ground floor. Microbes digest this decomposing material creating a completely decomposed, rich, and dark soil that returns nutrients to the new flora.

Buying Commercial Compost

If you haven’t tried compost when growing cannabis, by all means, give it a try. Very likely, it will be part of your cultivation protocol with all future grows.

The harvested compost needs aerating for 10-15 days in order to cure (finish the process), losing moisture. It also needs that microorganisms such as bacteria that can be found in other products like Bactohemp cease their activity. Once it is mature and dry, it can be stored in large sacks or hermetic-sealed bags. It is important to check for any excess moisture as it could rot.

If food waste is added to the heap, you should cover it with dry leaves or pieces of cardboard or paper. If you leave it exposed, flies may lay eggs on it and there is a risk of infestation with black fly on the substrate for cannabis.

Commercial composter. No doubt it’s the fastest and most convenient of all. They are usually made of plastic, there is an access from the top side to insert the waste. At the bottom there is a door from where you can collect the mature compost. With this type of composter you avoid problems with rodents attracted by the waste. Its design is ideal for composting at home without sacrificing aesthetics.

Using compost in a pot for growing marijuana outdoors: for marijuana plants, the right proportions are one part of compost for every three parts of soil light in nutrients. In long outdoor crops, you can make a second application during the last transplant, as long as the compost is mature, otherwise it shouldn’t be buried getting in contact with the trunk and roots.

Compost preparation process

Oxygen. The micro-organisms responsible for decomposition die without oxygen. If the mixture is too wet and pasty, the oxygen will hardly penetrate it. For the oxygen to reach throughout the mixture we have to turn it over from time to time. The more you turn it over, the more oxygen gets into the mixture, ensuring the life of microorganisms and facilitating an odour-free decomposition.

Using compost has many advantages, so we shold know the strenghts of this substrate to get the most of it.

Nitrogen. It provides proteins for microorganisms, and it is also called green material or greens. It includes kitchen waste, fruits, vegetables, grass clippings, manure, coffee grounds, tea bags, green leafs and pruning wastes.

Ingredients to make compost

Drum/Barrel composter. If you have a spare drum or barrel, then you have a composter. You only have to make some holes to start composting. A door at the bottom should be made in order to access the compost.
