🌞 Outdoor Notes

  • Climate: Warm, sunny (Mediterranean/light tropical)
  • Soil: Rich and well-draining
  • Harvest: Early October before chill sets in
  • Protection: Insect netting or neem oil for pests

Germination: Starting Your RS11 Grow

The paper towel method ensures consistent germination:

  1. Place seeds between two damp (not soaking) paper towels.
  2. Between two plates for darkness and breathability.
  3. Keep at ~70–75°F, check daily for taproots (~½ inch).
  4. When the taproot appears, plant root-tip down into your medium.

⚠️ Avoid sealing in plastic bags or exposing to direct light—rot and shock are real risks.
