Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Pros and cons of using cannabis seeds
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
The vast majority of photoperiod strains (strains that initiate bloom based on a change in light cycle) contain varying amounts of both indica and sativa genetics. Ruderalis, on the other hand, is a type of autoflowering cannabis that flowers based on age, and is often considered to be inferior to photoperiod cannabis morphologically. Although there is more to say in this regard, for the remainder of this article, we will be focusing mainly on the distinct characteristics of indica and sativa so the average grower can get a better idea of what to expect.
One of the major “drawbacks” you must watch out for with indicas is also one of their greatest strengths: dense buds. Indeed, as buds grow in size and put on weight, they become at much greater risk of developing mould, especially in humid regions with temperatures that foster pests and pathogens. Avoid this issue by carefully controlling environmental conditions inside, or by erecting necessary shelter outside (in case of rain, excess humidity, etc.). Having a small greenhouse or shed where you can hide your plants from inclement weather can be a great safety net.
The cannabis plant is versatile, hardy, and—unlike many kinds of plants—can survive in almost every climate in the world. However, thanks to evolution (and later on, selective breeding), the species has adapted to the landscapes in which it’s cultivated, and thus, vast variation between different cannabis plants is the norm today.
Thanks to the short growing cycle offered by indicas, not to mention their short stature, they can be quite convenient for home growers without too much time, space, or resources on their hands. Just think about it; a compact bush that finishes fast is easier to maintain (especially indoors) than a spindly, albeit majestic, tree. Even outdoors, indicas are resilient and laugh in the face of fluctuating temperatures—just remember where they came from. Moreover, the fast flowering time of indicas means outdoor growers can harvest before the first frost.
