Apr 22, 2016 = Day 0. Plants started from seed (Botanical Interests). 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). N-P-K (in ppm): 22-12-13.
Apr 25 = Day 3. Plant germinated, placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.
May 5 = Day 13. Installed plant into 1.125-gallon bucket. Hydroponic solution composed of 1.125 gal (4.3 L) tap water, 2.25 g MasterBlend 4-18-38, 2.25 g calcium nitrate, 1.125 g magnesium sulfate, 0.23 mL Dyna-Gro Pro-TeKt, 1.125 mL pH Down. N-P-K (in ppm): 103-41-168. pH = 6.0.
May 14 = Day 22. Moved plant to indoor grow room, receiving 8 hours LED light per day.
May 30 = Day 38. Trimmed plants down to encourage branching.
Jun 22 = Day 61. Trimmed plants again to encourage more branching.
Jul 9 = Day 78. Another plant has died, so I went ahead and harvested the last plant. Total fluid used = 3.5 cups (0.22 gallons). Final pH = 4.5. I’m not sure of why the pH had dropped so low. The roots looked terrible, poorly developed and brown in color.
