Meet Gruntz, a bold, indica-dominant hybrid with candy-sweet flavor, dense resin-coated flowers, and a deeply relaxing finish. Its 70% Indica / 30% Sativa balance pairs a soothing body feel with a bright, happy lift, making it an enticing pick for evening unwinding.

Our breeders created Gruntz from two celebrated American varieties: Gushers x Runtz. That flavorful lineage brings together rich fruit character, impressive resin production, and a powerful 25%–27% THC range.

The aroma opens with ripe berry and juicy grape, then unfolds into tropical sweetness, earthy depth, warm spice, and a sharp diesel note. Each inhale delivers a smooth, layered blend with a candy-like edge.

Expect a calming body high alongside gentle mental euphoria. Gruntz can leave you feeling cheerful, relaxed, and ready to slow down after a demanding day. Its potent, indica-led effects make it a popular choice among consumers seeking a calming experience.

Myrcene lends the profile its earthy, ripe-fruit character and supports Gruntz’s deeply relaxing feel. Caryophyllene adds peppery spice and a fuel-like edge. Together, these terpenes make a striking match for evening sessions and for growers seeking aromatic, resin-rich flowers suited to extracts.

These feminized seeds grow into female plants, simplifying cultivation and helping focus your space on flowering plants. Gruntz is photoperiod, with a 9–10 week flowering period. Germination is guaranteed, so you can start your grow with confidence.

Give seedlings a quality, well-draining medium such as coco coir or a balanced soil mix. Keep young plants supplied with appropriate nutrients as they move into vegetative growth, and provide steady light and airflow. A temperate environment helps support vigorous early development.

Gruntz grows to around 1.5 m and develops sturdy structure with branching that can support heavy flowers. Indoors, use ScrOG to create an even canopy and improve light access across the plant. Maintain clean airflow, manage humidity carefully, and monitor plants for pests throughout the grow.

After 9–10 weeks of flowering, expect dense, trichome-covered buds and high yields. Indoor growers can harvest around 500–600 g/m²; outdoor plants can produce approximately 500–600 g each in suitable conditions. Plan for an October harvest outdoors, with timing shaped by your local climate.
