Frequently Asked Questions

What makes classic strains worth growing in the modern era?
Decades of breeding refinement, proven genetics, and a massive library of community growing knowledge. They deliver predictable, documented results with well-understood growing requirements — the safest seed investment for any grower.
Can heritage strains compete with modern genetics on potency?
Many classics have been updated through selective breeding to reach modern potency standards. OG Kush, Gorilla Glue, and Girl Scout Cookies test above 25% THC. Some older cultivars like Skunk #1 carry lower THC but offer unique effect profiles and flavour character not found in contemporary lines.
