It takes two to measure our longest plants!
Fifth graders have noticed many changes to our Aquaponics system over the past month. We have exciting news: Not only have our plants grown longer, but our oldest fish seems ready to lay eggs soon!
As you can see, some plants have gotten much longer. When we first measured in October, the longest plant measured 1 inch long. Now it has grown to 7 inches! Although a few plants have gotten longer and greener, others have shriveled up. We have noticed that the plants near the bottom of the tubes are shriveled and pale, while the plants near the top are green, but short with small leaves. The plants near the middle of the tubes, where the most light reaches, are longer and greener, with broader leaves. Here's a view with the lights turned off:
See the difference?
We now wonder...
When will our "red leaf" lettuce actually turn red?
Will our oldest fish lay eggs over winter break?
Will the eggs survive winter break without someone to remove them from the tank with the adult fish?
How can we help the shriveled plants to grow stronger without harming the healthy plants?
