Lettuce – Adriana, Red Sails

Red Sails, a reddish loose-leaf variety, has been a dependable lettuce for me in the past.  I will be comparing it to a new lettuce, Adriana, a green butterhead variety.  Since my 3.5-gallon bucket will hold 3 plants, I will grow 1 Adriana plant and 2 Red Sails.

Dec 2, 2015 = Day 0.  Plants started from seed: Adriana (Johnny’s Seeds), Red Sails (Botanical Interests).  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.

Dec 10, 2015 = Day 8.  Adriana is at lower right.
Dec 18, 2015 = Day 16.  Adriana is at top.

Roots are now visible growing out of the bottom of the rockwool cubes, so it is time to install these plants into a larger 3.5-gallon bucket.

Dec 19, 2015 = Day 17.  Plants installed in 3.5-gallon bucket.  Hydroponic solution composed of 3.5 gal (13.25 L) tap water, 7 g MasterBlend 4-18-38, 7 g calcium nitrate, 3.5 g magnesium sulfate, 0.7 mL Dyna-Gro Pro-TeKt, 2.8 mL pH Down.  N-P-K (in ppm): 103-41-168.  pH = 6.5.

Dec 19, 2015 = Day 17.  Adriana is at top.
Dec 28, 2015 = Day 26.  Adriana at top.  Red Sails at bottom.

I thinned out the plants so that there are now only 2 plants growing out of each net-pot.

Jan 8, 2016 = Day 37.  Adriana (front), Red Sails (back)
Jan 20, 2016 = Day 49.  Adriana (front), Red Sails (back)
Feb 2, 2016 = Day 62.  Plants are ready for harvest.

Feb 28 = Day 88.  The entire Adriana plant has been harvested, only the 2 Red Sails plants remain.  The plant stems are getting quite long, but the leaves still taste fine.

Feb 28 = Day 88

Mar 10 = Day 99.  Harvested all leaves.  Final statistics:  3.2 gallons (12.1 L) of fluid used.  Final pH of fluid = 8.0.

Based on my experience, I conclude that Red Sails gives a better yield than the Adriana variety.  Both types of lettuce did well, but the Red Sails leaves were bigger and more plentiful than the Adriana.
