Medical Seeds

Spain (founded)

Founded in 2005 in Barcelona, Spain, by veteran cultivator and educator Javier Ruano, Medical Seeds was established with a clear mission: to combine high-level breeding expertise with rigorous genetic selection to produce premium cannabis seeds for therapeutic and connoisseur growers alike.

Medical Seeds approaches breeding with surgical precision, meticulously selecting, testing, and stabilizing elite global parent stock over long development cycles. By crossing prized European classics with exotic landraces and high-potency North American cuts, the seed bank has earned over 100 international cannabis cup trophies. Their catalog spans high-THC photoperiod feminized strains, specialized high-CBD and minor cannabinoid lines, and robust autoflowers—all tailored for high stress tolerance, exceptional resin production, and rich terpene complexity.

Their world-renowned catalog features iconic flagship strains such as Y Griega (a soaring sativa boasting over 27% THC), Channel +, 1024, 2046, Devil Fruit, and Mendocino Chanel Kush. Renowned globally for consistency, high germination viability, and versatile therapeutic potential, Medical Seeds remains an international benchmark for professional-grade Spanish breeding.
