Defender Romaine Lettuce Raft Hydroponic Test-
27 days from seeds to dinner salads. These pictures were taken during our second LED lit lettuce raft using Defender Romaine Lettuce seeds.
LETTUCE RAFT -
Total of 29 days from seeds to dinner salads.
We planted dry seeds into twelve sponges. The seedlings sprouted and were inserted into the lettuce raft on day three. The seedlings were so small they are difficult to see (Image 1). Four days later we had significant growth (Image 2). The next image was taken on day 11 (Image 3), and again, we found that the lettuce was growing very well. Over the next 18 days we simply monitored our nutrition levels, and left the timer on the light, while documenting with pictures periodically (Images 4-9).
We harvested the lettuce on Day 29, due to concerns about overcrowding. We pulled the plants and disconnected them at the base, so that our weights would not be padded by the weight of the roots. We balanced our scale at zero before each plant to ensure accuracy. With twelve plants, we averaged a weight of 58.42 grams per plant. Our highest weight was 102 grams, and the lowest, 31 grams.
