Calypso cilantro is a typical variety of cilantro (also known as coriander). This variety is supposed to be very heat tolerant. Growing 3 plants in a 5-gallon bucket.
Nov 8, 2015 = Day 0. Plants started from seed (Park Seed). Moistened with dilute fertilizer: Dyna-Gro Liquid Grow, diluted 1 mL (1/5 tsp) per gallon of tap water. Nutrient concentrations (in ppm): N 18, P 24, K 13, Ca 5, Mg 1, S 0.13, Fe 0.26, Mn 0.13, B 0.05, Zn 0.13, Cu 0.13, Mo 0.002, Ni 0.0003, Co 0.004. pH = 7.0.
Nov 13 = Day 5. Seeds germinated. Transferred to grow room, receiving 3 hours sunlight + 5 hours LED grow-light per day.
Nov 26 = Day 18. Plants installed in 5-gallon bucket. Hydroponic solution composed of 5 gal tap water, 10 g MasterBlend 4-18-38, 10 g calcium nitrate, 5 g magnesium sulfate, 1 mL Dyna-Gro Pro-TeKt, 4 mL pH Down. 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 = 6.5.
These plants are looking great, I haven’t done any thinning yet, so every plant that germinated is still growing (2-5 plants per net-pot). I may need to thin some plants out soon.
Jan 3 = Day 54. Plants thinned down to just 1 plant per net-pot. I should have done this thinning long ago, because the leaves had become quite interwoven, requiring lots of tedious work to separate them.
I have been harvesting leaves off these plants every week or so, and they just keep on producing more. It’s great to always have fresh cilantro on hand.
Feb 24 = Day 106. Still harvesting lower leaves every week. Plants look great, still going strong. Container is starting to get light, so I added 0.5 gallons of fresh hydroponic fluid.
Mar 1 = Day 112. Added 0.75 gallons of fresh hydroponic fluid.
Mar 12 = Day 123. Added 1 gallon of fresh hydroponic fluid.
Apr 9 = Day 151. Added 0.25 gallons of fresh hydroponic fluid.
Apr 17 = Day 159. Harvested all remaining leaves. Total fluid usage = 7 gallons for 3 plants (2.3 gal/plant).
