The 8 Best Cannabis Seeds for Indoor and Outdoor Growing

Whether you have thought of growing your own cannabis plants or are already experimenting with some strains, choosing the best marijuana seeds and achieving excellent results requires some knowledge and preparation.

Cannabis strains can be divided into three broad groups: Indica, Sativa, and Hybrid. Indica Is characterized by a relaxing effect, Sativa is energizing, and Hybrids are a mix between both. However, some experts argue that these three categories are too wide to accurately portray the different effects each strain has.

The following strains are suitable for both indoor and outdoor growers, as they can provide high-quality yields regardless of whether they are grown under the sunlight in an open field or in a traditional or hydroponic indoor garden.

Below you will find The Best Marijuana Strains to grow on your own.

An 80% Sativa hybrid, the G13 Gaze has won multiple awards for its uplifting and mind-clearing effects. Unlike other strains with higher percentages of Indica, the G13 does not cause any lethargy or lack of energy, and can even spark creativity without causing concentration problems.
