Precision Cultivation: Why Old Fashioned Sunshine is “Strain of the Month”

We are proud to announce that Old Fashioned Sunshine has been featured as the Strain of the Month in the April 2026 issue of Oregon Leaf magazine. This recognition highlights the power of Controlled Environmental Agriculture (CEA) when combined with rigorous data tracking. At our SUNSCAPE Innovation Center (Kanaba Farms), we don’t just grow plants; we iterate on their performance to unlock their full genetic potential.

 

For new operators entering competitive markets like Minnesota, these trials prove that technical environmental control is the most reliable path to superior quality and yield.

The Evolution of Excellence: Comparing Harvest 26-8 and 26-9

In commercial cultivation, standing still is the same as falling behind. By analyzing physical growth metrics across multiple trials of the Old Fashioned Sunshine monocrop, we identified clear opportunities for morphological improvement.

 

Growth Metric Comparison Table

Metric Harvest 26-8 (Day 54 Flower) Harvest 26-9 (Day 41 Flower) The Data-Driven Result
Base Stem Thickness

15.0 mm

16.96 mm

A 13% increase in the plant’s “nutrient highway”.
Average Bud Size

29.17 mm

32.4 mm

Larger, denser buds despite being 13 days younger.
Canopy Height

5 feet

5 feet

Consistent height management for optimal light penetration.
Morphological Observation

Loose stacking; small top buds.

Tight stacking; small internodal spacing.

Significantly fuller flower development on all branches.

Overcoming Environmental Heat Stress in CEA

Data is most valuable when it identifies failure points. During the Harvest 26-8 trial, our facility faced significant environmental challenges.

  • The air conditioning units struggled to maintain set points, leading to table temperatures of 87°F.

  • This heat stress caused visible leaf tip curling in the upper canopy.

  • The high temperatures likely contributed to the looser stacking and smaller buds observed in that run.

By the time we initiated Harvest 26-9, we adjusted our environmental responses. These technical pivots resulted in “better stacking” and fuller colas, proving that even with the same genetics, the environment dictates the final ROI.

 

Priming for Success: The Vegetative Strategy (H26-13)

The foundation of a “Strain of the Month” harvest begins weeks before the flowering flip. Our current vegetative trial, Harvest 26-13, is being steered for maximum vigor.

  • Strategic Topping: At Day 17, plants were topped to promote side branching and ensure canopy uniformity.

  • Vigor Metrics: Plants currently average 9 to 11 inches in height with a base stem diameter of 6.16 mm.

  • Light Intensity: Lights are lowered on carabiners to run at full blast, achieving 500 PPFD to drive rapid biomass accumulation.

  • Irrigation Control: The team maintains a “slow, small dryback” to ensure the media reaches daily field capacity as the plants approach their peak drinking phase.

     

The Bottom Line for Commercial Growers

Whether you are managing a monocrop trial or navigating your first year in a new market, data-driven cultivation removes the guesswork. The “Old Fashioned Sunshine” case study demonstrates that by monitoring stem thickness, bud diameter, and internodal spacing, you can turn environmental challenges into a roadmap for yield optimization.
