Fan leaves will turn yellow However, if your plant is loaded with flowers, fan leaves will begin to turn yellow and die, as much of the resources are directed towards the buds. This is an easy to detect and sure sign that harvest time is near. The flowering stage in cannabis plants is usually 8 to 11 weeks, depending on the strain. It is usually divided into weeks or three stages.
The flowering period for Indica varieties is usually around 8 weeks, but can take up to 10 weeks.
Sativa
strains can take 10 to 12 weeks. Typically, hybrid strains will take 6 to 10 weeks to fully develop. Indica varieties bloom faster than sativas, forming flowers after seven to nine weeks on average.They continue to bloom for up to twelve weeks. Many Indicas slow their upward growth as they begin to bloom and instead become bushier, with branches and leaves fanning out. Its shelf life is three to four months. In places on the plant where you had previously seen some hairs, you can now see the first signs of real bud development.
There won't be many resin glands and trichomes on your plants yet, which means the smell won't be too pungent either. As the cannabis flower reaches maturity, more pistils turn red or brown. A good rule of thumb is to harvest when just over 50 percent of the pistils have turned red or brown. The naked eye method is good for beginners who don't have access to a magnifying glass or microscope.
Indica and Sativa, the most commonly recognized cultivars, have distinctive physical characteristics and growth characteristics. On the other hand, Sativa plants grow much taller and have very thin leaves, with flexible stems and a much longer flowering period. For a hybrid cannabis strain with Sativa dominant traits, flowering periods may be longer and for strains with Indica dominant traits, they may be shorter. Sativa cultivars are not ideal for home growers who want to grow indoors or within a restricted space.
How long a Sativa or Indica plant stays in a vegetative state depends entirely on its exposure to light. But I really want a heavy head, if I harvest when amber is 10% as indicated, will it be heavy in sativa genetics? thank you. For example, I tend to harvest Sativas with fewer amber trichomes than Indicas, since I want a more stimulating and energetic effect. The general lifecycle of sativas can last up to six months, resulting in a longer growth period than indicas.
Sativa buds are ready to harvest when most of the trichomes, or resinous glands in the buds, appear milky white with only an occasional light trichome in the mix. Hybrid varieties are also common, and many growers choose plants that combine the most desirable properties of both Sativa and Indica. Cannabis sativa plants originated near the equator and thrived in temperate regions with mild winters and long summers. These are the guidelines for Indica, Sativa and Hybrid strains, but the guidelines for individual strains are even more precise.
If you're growing Sativa strains from seed, try to achieve an optimal temperature of 75°F (24°C) to encourage germination within three to seven days. If you're thinking about growing cannabis and wondering whether to grow Indica or Sativa, your choice is likely based on the types of effects you want to experience. When it comes to growing cannabis, the first decision is to determine whether to grow indica or sativa plants.
