Top 10 Fastest Flowering Cannabis Strains You’ll Adore Growing

There are three types of cannabis that you can grow at home: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis sativa plants are taller, statelier and will grow large leaves. C. indica plants are smaller and have compact structures. On the other hand, C. ruderalis strains are the smallest strains and have very few leaves and buds.

With these differences in plant size and structures, these three types of cannabis strains also grow differently. Because sativas are taller and lankier, these tend to grow the slowest. Meanwhile, indica strains grow faster than sativas but of the three, ruderalis strains are the quickest.

Cannabis ruderalis are autoflowering varieties of cannabis and can grow in just 7 to 9 weeks. This fast growth allows the ruderalis to grow as much as two to three crops per year. Autoflowering strains also don’t need a special flowering light schedule, unlike photoperiod strains. This means that ruderalis strains will bloom by the time the plants have matured and not according to a strict schedule.
