There is a trend towards an increase in the number of cultivators who are using sustainable methods for growing cannabis. To improve the soil, they mainly use: special AACT inoculations, growing companion crops, and even grazing goats, which loosen and aerate the soil with their hooves, and their droppings are used as a natural fertilizer.

Watering frequency and amount is determined by many factors, including temperature and light, the age, size and stage of growth [22] of the plant and the medium's ability to retain water. A conspicuous sign of water problems is the wilting of leaves. [23] Giving too much water can kill cannabis plants if the growing medium gets over-saturated.
Indeed, plants growing in a typical traditional gravel filter bed, with water circulated using electric powerhead pumps, are in effect being grown using gravel hydroponics, also termed "nutriculture". Gravel is inexpensive, easy to keep clean, drains well and will not become waterlogged.
A manual backpack-type sprayer Space treatment against mosquitoes using a thermal fogger Grubbs Vocational College students spraying Irish potatoes. Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
The efficiency of the spray and reach of the spray drift can be computed. [14] In addition to weather, windbreaks can mitigate the effects of drift. [ 15 ] Other ways to mitigate spray drift is to apply the pesticide directly to the desired treatment area, as well as paying attention to where surface waters, gutters, drainage ditches, and storm ...
Containerized transplants or plugs allow separately grown plants to be transplanted with the roots and soil intact. Typically grown in peat pots (a pot made of compressed peat), soil blocks (compressed blocks of soil), paper pots or multiple-cell containers such as plastic packs (four to twelve cells) or larger plug trays made of plastic or ...
Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...
