FAQs: Medical Cannabis Seedbanks in 2025

1. What makes a seedbank “medical-grade”? A medical-grade seedbank provides lab-tested genetics, publishes cannabinoid and terpene profiles, and follows compliance standards for safe, traceable distribution.

2. Can patients legally grow their own medical cannabis? In many countries and U.S. states, licensed patients can cultivate a limited number of plants for personal use. Always verify local laws before germinating seeds.

3. Which strains are best for anxiety and stress relief? Balanced hybrids like Blue Dream and Royal Highness (RQS) are top-rated for anxiety due to moderate THC levels and soothing terpene blends.

4. Are high-THC strains suitable for medical use? Yes, but they should be used with guidance. Strains like Sour Diesel and Critical Kush can alleviate pain and depression but may cause overstimulation in sensitive users.
