Cilantro – Calypso

calypso20cilantroCalypso cilantro is currently growing in my house, but after 3+ months of reliable weekly harvests, the plants are starting to bolt (sending up a flower stalk), so they are probably nearing the end of their useful life.  I will start up some new plants at this time.

Mar 20, 2016 = Day 0.  Plants started from seed (Park Seed).  Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot.  Moistened with dilute fertilizer solution: 1.2 mL Dyna-Gro Liquid Grow, 0.8 mL pH Down per gallon of tap water.  Nutrient concentrations (in ppm):  N 22, P 29, K 16, Ca 6, Mg 1.6, S 0.2, Fe 0.3, Mn 0.2, B 0.1, Zn 0.2, Cu 0.2, Mo 0.003, Ni 0.0003, Co 0.005.  pH = 6.0.

Mar 25 = Day 5.  Plant germinated, placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.

Mar 29 = Day 9

Mar 31 = Day 11.  In 1 of the net-pots, the plants are too leggy and unable to stand up.  I will re-start that net-pot with fresh seeds.

Apr 7 = Day 18.  Installed plants into 5-gallon bucket.  Hydroponic solution composed of 5 gal (18.9 L) tap water, 75 mL 250x Masterblend 4-18-38, 75 mL 250x calcium nitrate, 75 mL 250x magnesium sulfate, 1 mL Dyna-Gro Pro-TeKt, 5 mL pH Down.  (This solution is equivalent to 5 gallons water, 10 g Masterblend, 10 g calcium nitrate, 5 g magnesium sulfate).  Nutrient concentrations (in ppm):  N 103, P 95, K 202, Ca 100, Mg 29, S 34, Fe 2.1, Mn 1.1, B 1.1, Zn 0.3, Cu 0.3, Mo 0.05, Si 4.  pH = 6.0.  Plants moved to indoor grow room, receiving 9 hours LED grow light per day, plus 3 hours sunlight per day.
