Lolla Rossa is a frilly, loose-leaf green/red lettuce variety.
Jun 18 = Day 0. Plants started from seed (Botanical Interests). Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot. Moistened with Seedling Blend, a dilute blend of fertilizers. N-P-K (in ppm): 22-29-16.
Jun 22 = Day 4. The plant has germinated, and was placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.
Jul 1 = Day 13. Installed plant into 3.5-gallon buckets using the Masterblend-based Regular-Strength Blend. N-P-K (in ppm): 103-95-202. Plant moved to indoor grow room, receiving 9 hours LED grow light per day.
Aug 12 = Day 55. Began harvesting lower leaves for use in salads. Plant is getting too tall and top-heavy, so it was tied to a pole to keep it upright. Also, grow room is very hot (above 80 °F during the day), so the use of the LED grow light was discontinued. Plant is now receiving 3-4 hours of direct sunlight per day.
Sep 2 = Day 76. All lower leaves have been harvested, and the plant has bolted, so the remaining upper leaves taste bitter. This plant has grown to be almost 4 feet tall! Plant was discarded at this time. Total fluid used = 2.8 gallons. Final pH = 5.0.
