Dinafem is a Spanish seed bank that revolutionized the European market by introducing the first commercial feminized versions of classic strains. The company was founded in the early 2000s (2002–2005) by a team of enthusiasts connected to the La Mota growshop in San Sebastián. Their goal was to provide growers with fully female, stable seeds to eliminate the problem of unwanted male plants. The initial catalog included only six strains, but thanks to innovative feminization and selection methods, it quickly gained a strong reputation.
Growth and key achievements
Feminised revolution – Dinafem was the first company in Spain to offer feminized versions of popular classics such as Critical+, Moby Dick, and Industrial Plant.
Autoflowering and CBD – the company soon introduced autoflower lines (including Amnesia Auto, Blue Kush Auto) and CBD‑rich lines (CBD Kush, Dinamed CBD) aimed at medical users.
Global reach – within less than a decade, Dinafem seeds were available in most European grow shops; the brand collaborated with the best genetic banks worldwide.
Legal approach – from the start they emphasized legality and responsibility, noting that seeds are intended for collection and research (in accordance with the law).
Notable strains
Dinafem’s catalog included classics and modern hybrids. Particularly famous were:
Moby Dick – a Haze x White Widow cross with THC up to 21%, delivering a powerful, long‑lasting psychoactive effect and abundant yields.
Critical+ – an improved version of Critical from Mr Nice; flowers in 45–50 days, yields up to 1,300 g per plant outdoors, while keeping an intense fruity aroma.
Industrial Plant – an Afghani x Thai hybrid for growers who value short flowering and industrial‑scale yields (up to 625 g/m²).
Original Amnesia – a Dutch classic refreshed in a Spanish edition; a tall, vigorous plant with an energizing, citrus high.
Growing tips
Dinafem produces seeds that are easy to handle even for beginners, but optimal results come from a few guidelines:
Light – most feminized strains prefer 600–1000 W indoors; autoflowers respond better to 18/6 or 20/4.
Resistance – seeds are selected for resistance to fungi and disease; however, in humid climates good ventilation is recommended.
Techniques – strains like Moby Dick or Critical+ love SOG/SCROG and topping; autos are best left uncut.
Medium – a soil mix with coco fiber and perlite provides proper drainage and oxygen access to the roots.
