Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.
All dimensions of the symbol and the leaf silhouette (a novel design by David and Eli Nathan) are defined in ASTM D8441/D8441M. The state of Vermont approved use of the IICPS before the ASTM standard was published, and their choice of a different color scheme is now out of compliance with the ASTM D8441/D8441M standard.
Autoflowering cannabis or day neutral cannabis varieties automatically switch from vegetative growth to the flowering stage based on age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowering varieties are ready to harvest in less than 10 weeks from seed.
Seedless cannabis (sin semilla) Seeded cannabis (con semilla)Cannabis sinsemilla (Spanish pronunciation: [sinseˈmiʝa]) also known as sensimilla, sinse or sensi (can be translated into English as seedless cannabis) is the female Cannabis plant that has not been pollinated and therefore does not develop seeds, increasing the concentration of cannabinoids and terpenes.
Reduced tillage [note 1] leaves between 15 and 30% crop residue cover on the soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements.
Tilling can create a flat seed bed or one that has formed areas, such as rows or raised beds, to enhance the growth of desired plants. It is an ancient technique with clear evidence of its use since at least 3000 B.C. [8] No-till farming is not equivalent to conservation tillage or strip tillage. Conservation tillage is a group of practices ...
It is used after ploughing for breaking up and smoothing out the surface of the soil. The purpose of harrowing is to break up clods and to provide a soil structure, called tilth, that is suitable for planting seeds. Coarser harrowing may also be used to remove weeds and to cover seed after sowing.
A flowering cannabis plant. When cannabis is cultivated for its psychoactive or medicinal properties, male plants will often be separated from females. This prevents fertilization of the female plants, either to facilitate sin semilla flowering or to provide more control over which male is chosen. Pollen produced by the male is caught and ...
