This RF3 upgrade produces uniform, vigorous plants with tighter stacking, denser buds, and improved extraction yields, perfect for hashmakers and flavor hunters. The terp profile has been sharpened into a richer, sweeter guava blend with creamy fruit layers, filling the room long before harvest.

She grows fast, strong, and resilient in any environment, showing exceptional resistance to pests, mold, and environmental stress. Expect impressive yields of rock-hard, frost-heavy buds without demanding heavy feeding or complex training. With up to 30% potency, the effect is bright, uplifting, and functional: a joyful, creative high followed by a smooth, relaxing body feel that stays productive and social.

Guava Auto RF3 is the most consistent, flavorful, and extraction-ready expression of Guava Auto to date, engineered for growers who want tropical terps, bulletproof performance, and premium-quality resin in every run.

Love
how these flowers look. I feel like I can almost smell them, by simply watching your footage. I'm incredibly excited about the whole RF3 lineup and just know they'll win one award after the next. Fastbuds are by far my favorite breeders. Keep up the great work 💪 🪴🏆

Chubbs next favorite?
I'm betting this will be Chubbs favorite or his next cup winner. I'm waiting on my Cherry Cola Auto RF3 to arrive. I'll have to add this to my list or be lucky and win a pack in the meantime.
