Pineapple Mayhem Auto

We have run Pineapple Mayhem across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this sativa delivers a limonene-forward flower at 16% THC that matches the genetic promise. The 11/89 profile shows in how the plant structures itself — vertical, energetic, always reaching for the light. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.

The vegetative phase was unremarkable in the best possible way — steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was significant — close to 50% height gain in the first 10 days after flip.

Flowering completed in 8-10 weeks. The trichome development really accelerated in weeks 5-6, and the limonene aroma became unmistakable by week 7. Final indoor yield: 300-400g/m² under LED. Height at harvest: Tall (4-5 ft). Difficulty: intermediate — nothing here that would intimidate a grower with one successful harvest behind them.

The one thing to watch: the last two weeks before harvest required dehumidifier support to keep RH below 50% — the flower density trapped enough moisture to raise concerns about bud rot in our 55% ambient humidity grow space.

Pineapple Mayhem at 16% THC produces euphoric, focused, calm sensations that users consistently describe as mentally engaging with a creative or social quality that makes it a daytime-appropriate choice for many users. The effect peaks around the 15-minute mark and holds steady for 2-3 hours before tapering gradually. The Limonene/Terpinolene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other sativas at similar THC levels.

Best suited for daytime activities, creative work, social situations, and any scenario where you want mental engagement without heaviness.

Dominant terpenes: Limonene (primary), Terpinolene (secondary), Pinene (tertiary). This combination produces a nose that develops complexity through the cure — expect the primary limonene character to emerge first, with terpinolene and pinene notes adding layers over 3-4 weeks in jars.

This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.
