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.
Mar 26, 2015 = Day 0. Plant started from seed (Park Seeds). 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.
Mar 29, 2015 = Day 3. Seeds germinated. Transferred to grow room, receiving 14 hours LED grow-light per day.
Apr 10, 2015 = Day 14. Plant installed outside 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. 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.
May 31, 2015 = Day 61. Began harvesting cucumbers.
Throughout Jun 2015, a total of 14 cucumbers were harvested. In early July 2015, I accidentally let the bucket run dry. I added 5 gallons fresh hydroponic fluid, but it was too late and the plant died. I should have been more vigilant in checking the fluid level. A big cucumber plant like this uses a lot of water in the summer heat. In the case of these big buckets, just tip them slightly to check their weight. If they are easy to tip, add some fluid.
