💧 Hydroponic Notes

Exceptional in Kratky or NFT systems. Grows year-round indoors. Prefers cooler temperatures (50–70°F). Ready to harvest in just 3–4 weeks.

Non-toxic in normal amounts; contains oxalates like many greens, so very large amounts aren't ideal for pets with kidney issues.

Informational only — always check with a veterinarian if you suspect your pet has eaten something it shouldn't have.
