Cucumber – Diva

Diva has a lot of advantages over other varieties of cucumber.   First, it is parthenocarpic, meaning that fruit is produced even in the absence of pollination.  Second, this variety is resistant to a number of diseases, including Powdery Mildew.

Jul 6, 2015 = Day 0.  Plant started from seed (Park Seeds).  Moistened with dilute fertilizer: Dyna-Gro Liquid GROW 7-9-5, diluted 1 mL (1/5 tsp) per gallon of tap water.  N-P-K (in ppm): 18-10-11.  pH = 7.0.

Jul 10, 2015 = Day 4.  Seeds germinated.  Transferred to grow room, receiving 14 hours LED grow-light per day.

Jul 22, 2015 = Day 15.  Plant installed in 32-gallon bucket.  Hydroponic solution composed of 32 gal tap water, 64 g MasterBlend 4-18-38, 64 g calcium nitrate, 32 g magnesium sulfate, 6.4 mL Dyna-Gro Pro-TeKt, 25 mL pH Down.  N-P-K (in ppm): 103-41-168.  pH = 6.5.  Plant is getting about 4-5 hours of direct sunlight each day.

Sep 11, 2015 = Day 67

Sep 28, 2015 = Day 84.  Began harvesting cucumbers.

Oct 1, 2015 = Day 87.  Major infestation of inchworms.  The cucumbers are unaffected, but the leaves look terrible, lot of holes in them.  Removed inchworms by hand daily.  This was a lot of work, next year I will probably just spray the whole plant with an organic pesticide, like Bt.

Continued to harvest cucumbers until mid-Nov.  Fresh hydroponic fluid was added several times when the bucket felt light.  Nights started getting cold, and plant was discarded in mid-Nov.

Total harvest = 24 cucumbers.  Total water used = 45 gallons.
