Who is Grass-o-matic?

Grass-o-matic is a Spanish brand from Valencia that was among the first to produce exclusively autoflowering seeds. Founded in 2005, it became a pioneer in creating fully feminized autoflowers. Thanks to cooperation with the breeder known as Joint Doctor, it managed to stabilize strains such as Easy Ryder and Maxi Gom, which entered the canon of classics. All seeds in the Grass-o-matic catalog are 100% feminized and auto, meaning plants begin flowering regardless of day length after 3–4 weeks of growth and complete their life cycle within 65–75 days from germination.

Why choose this seed bank?

Grass-o-matic focuses on quality and stability. Their team concentrates on a small number of strains, allowing each project to be refined. The seeds feature high germination rates, and trait repeatability is noticeably higher than with many other autoflowers. The lineup includes classic sativas, indicas, and hybrids in auto form, including Haze Gom—an autoflower version of Haze with impressive growth, high-yielding Maxi Gom, and Med Gom 1—a collaboration with CBD Crew featuring high cannabidiol content. The latter proves Grass-o-matic also cares about medical users’ needs, offering CBD-rich seeds to help ease pain and anxiety.

Growing tips for Grass-o-matic autoflowers

When growing Grass-o-matic plants, remember their life cycle is fixed. You can’t extend the vegetative phase by changing the photoperiod, so a strong start is crucial. Use 7–15 L pots and plant directly into the final container to avoid root stress. Running 18/6 or 20/4 light throughout the entire cycle helps maximize plant potential. Because the plants are relatively small and flower quickly, they respond well to gentle training (LST) and removing lower leaves to improve airflow. You can also apply defoliation in week 3 of life to increase light access to the main stems.

Autoflowering is an excellent choice for beginners and balcony gardeners: plants are discreet, tolerant of minor mistakes, and allow multiple harvests per season. Keep in mind, however, that heavy feeding can overwhelm them; it’s better to use balanced nutrients that provide appropriate NPK ratios for a fast cycle. Outdoors, Grass-o-matic plants need 5–6 hours of direct sun per day, and in cooler climates it’s worth considering a small greenhouse. After an outdoor harvest, you can easily start a second cycle in the same season, making Grass-o-matic autos ideal for getting the most out of summer.

The bank places strong emphasis on packaging and shipping: seeds are packed in discreet, airtight packaging that protects against moisture and damage. This ensures they reach the customer in perfect condition. Grass-o-matic doesn’t offer hundreds of strains, but the available ones are precisely selected and often tested by the community. Growers value them for genetic stability and ease of cultivation even in limited space.

If you dream of fast harvests and discreet plants, Grass-o-matic offers a set of proven seeds that perform great both in home grow boxes and on a sunny balcony. The brand proves an autoflower can be stable, tasty, and productive, and CBD-rich medical versions broaden the offer for those seeking alternative relief.
