Ever wanted to grow your favorite strain? Leafly and General Hydroponics are teaming up on a series of grow guides that will equip you with all the tips and tricks you need to grow different strains successfully.


Strain Overview: Produced by Barney’s Farm, Critical Kush was bred by crossing Critical Mass with OG Kush. Known for its spicy, earthy flavor and overwhelming yield, this strain remains popular among growers and consumers alike.

Grow Techniques: Provide plenty of space for these plants when you grow them. Prune aggressively and trellis the branches so that the buds have room to fill in. Maintain low humidity while flowering and keep airflow up to prevent bud rot. Grow either hydroponically or in soil and keep the buds out of the rain if growing outside. Critical Kush is a great option for growing in greenhouses if you’re looking for a large harvest.
