Endive – Perlita

52473-pk-p1

Endive is a leafy green that is similar to lettuce, but with a slightly thicker leaf.  The leaves remind me of a Romaine type of lettuce.

May 28, 2016 = Day 0.  Plants started from seed (Park Seed Co.).  Seeds sowed in 1.5-inch rockwool cube in 2-inch net-pot.  Moistened with Seedling Blend, a dilute blend of fertilizers.  N-P-K (in ppm): 22-29-16.

May 30 = Day 2.  Plant germinated, placed directly under a fluorescent light (2 ft. T8 bulb, 17W, 6500k) for 16 hours per day.

Jun 6 = Day 9

Jun 15 = Day 18.  Installed plant into a 2-gallon bucket using Jungle Juice Blend, a regular-strength fertilizer blend.  N-P-K (in ppm): 113-79-147.  Plant moved to indoor grow room, receiving 9 hours LED grow light per day.

Jul 25 = Day 58

Aug 4 = Day 68.  Container was almost empty, so I added 0.75 gallon of fresh fluid, this time using the Masterblend-based Regular-Strength Blend.  N-P-K (in ppm): 103-95-202.

Aug 11 = Day 75

Aug 13 = Day 77. Added 0.5 gallon Regular-Strength Blend.  Leaves are now developing a spicy flavor.  Also, indoor grow room is very hot (> 80 °F during the day), so the use of the LED grow light was discontinued.  Plant is now receiving 3-4 hours of direct sunlight per day.

Aug 25 = Day 89.  Added 0.75 gallon Regular-Strength Blend.

Sep 3 = Day 98.  Added 0.25 gallon Regular-Strength Blend.

Sep 11 = Day 106.  Added 0.75 gallon Regular-Strength Blend.

Sep 17 = Day 112.  I have been continuing to harvest the lower leaves for salads, and they have been tasting great.  Unfortunately, I recently discovered mites on a few of the leaves, so rather than deal with the mites, I will discard the plant at this time.  This plant did very well for me, providing many salads.  Total fluid used = 4 gallons.

Apr 19 = Day 12.  Installed plant into 2-gallon bucket.  Hydroponic solution composed of 2 gal (7.6 L) tap water, 30 mL 250x Masterblend 4-18-38, 30 mL 250x calcium nitrate, 30 mL 250x magnesium sulfate, 0.4 mL Dyna-Gro Pro-TeKt, 2 mL pH Down.  (This solution is equivalent to 2 gallons water, 4 g Masterblend, 4 g calcium nitrate, 2 g magnesium sulfate).  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.  Plant moved to indoor grow room, receiving 9 hours LED grow light per day, plus 3 hours sunlight per day.

May 26 = Day 49

Jun 5 = Day 59.  Added 0.5 gallon fresh hydroponic fluid.

Jun 12 = Day 66.  Plant leaves are getting tougher and have a bitter taste.  It would be better next time to only harvest leaves from the younger plant, since the leaves were more tender and tasty.  Discarded plant at this time.  Total fluid used = 1.9 gallons.
