Bok Choy – Toy Choy

bok-choy-toy-choy-seedsToy Choy is a miniature variety of Bok Choy (also called Pak Choi, Chinese cabbage), growing just 5 inches tall.

Dec 24, 2015 = Day 0.  Plants started from seed (Botanical Interests).  Moistened with dilute fertilizer solution: 1 mL (1/5 tsp) Dyna-Gro Liquid Grow 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.

Dec 27 = Day 3.  Seeds germinated.  Transferred to grow room, receiving 3 hours sunlight + 5 hours LED grow-light per day.

Jan 2 = Day 9

The photo above is a great example of what happens when seedlings don’t get enough light.  They grow tall and ‘leggy’, reaching for more light, and then they are too weak to stand upright later in life.  I need to provide my seedlings with more light.

Jan 4 = Day 11.  To give plants more light, placed plants directly under a fluorescent light (2-ft. T8 bulb, 17W, 6500k) for 14-16 hours per day.  Plants are only 1-2 inches away from the light.

Jan 7 = Day 14

Jan 8 = Day 15.  Installed plants into 3.5-gallon bucket.  Hydroponic solution composed of 3.5 gal tap water, 7 g MasterBlend 4-18-38, 7 g calcium nitrate, 3.5 g magnesium sulfate, 0.7 mL Dyna-Gro Pro-TeKt, 3.5 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 = 6.0.  Plants moved to indoor grow room, receiving 8 hours LED grow light per day.

Feb 24 = Day 62

Feb 24 = Day 62.  At this point, the lower leaves are turning yellow and falling off at about the same rate that new leaves are forming, so it is time to harvest these plants entirely.

Final Stats: 7 plants harvested.  1.25 gallons of fluid used.  Final pH of fluid = 7.0.

To prepare, chop the bok choy plants, steam for about 5 minutes, then coat with a dressing of olive oil, fresh garlic (minced) and ground black pepper.  Delicious!
