Cannabis is often associated with relaxation, calm, and rest. The image that comes to mind for a lot of people when thinking of the herb is a red-eyed person sunk deep into a couch with not a lot to say. Although there are certainly a vast variety of strains that will produce this deeply stoning effect, there are an equal amount that have the complete opposite outcome. Many cannabis strains are highly stimulating, energetic, cerebral, and induce a cognitive high that boosts creativity, focus, and concentration.

These cannabis strains are ideal before sitting down for long periods of work, writing, making music, and painting pictures. Many athletes and active individuals also use these strains before exercise and recreational activities to boost awareness, enter flow states, and possibly improve performance. Here are the top 5 strains to boost focus.

SOUR DIESEL

Lighting up a bowl or joint loaded with Sour Diesel is an excellent strategy before pouring your energy into a creative project. This sativa-dominant strain features 70% sativa genetics and 30% indica genetics. She is the product of a breeding project involving Original Diesel, Northern Light, Shiva, and Hawaiian. This diverse genetic mixture results in a strain that has a THC content of 19% alongside medium levels of CBD. The high from this strain is extremely clear, crisp, and physical. It allows the user to get into the zone without trailing into trippy thought patterns or losing focus. The flowers of this strain house sensory pleasures in the form of sour and herbaceous flavours.

Sour Diesel can be grown with great success both indoors and outdoors. Indoor plants are capable of producing yields of between 475–525g/m² and growing to heights of up to 160cm. Plants cultivated outdoors will provide harvests of up to 600g/plant, and can reach up to 200cm. Sour Diesel has a flowering time of approximately 10–11 weeks, with outdoor plants ready for harvest during late October.

The lovechild of parent strains Chemdawg, Lemon Thai, and Pakistani Kush, OG Kush is an indica-dominant strain featuring 75% indica genetics and 25% sativa genetics.

A THC content of 19% along with medium levels of CBD make for highs that set in fast and linger for some time.
