Growing notes

Purple Lemonade Auto RF3™ suits indoor, outdoor, greenhouse, and mixlight setups, giving you flexibility regardless of your situation. Expect plants between 31 and 51 inches tall at harvest, so allow vertical headroom indoors. The full cycle wraps in 9–10 weeks from seed. Outdoor growers can expect wide yield variation — 2 to 11 oz per plant — depending on climate and care.
