The two Kratky kale plants have a nice root system.  The Kratky spinach plants are developing.  So this morning I took two of the black-seeded simpson lettuce starts I have going on in a tray and set it up to Kratky!

In the picture below you will see two of the lettuce plants, in their infancy, and their roots well cleaned of the soil in which it got its start.  Carefully I dangle the small root system into net cups and gingerly drop small clay balls called Hydroton into the net cups and around the roots.  The old and empty northern bean jars are filled with high nitrate water from my fish tank to about a quarter of an inch above where the bottom of the net cup is.

I think I want to look in through the clear jar and water to see how the roots will stretch down below the net cups and into the nutrient rich water, so I won’t cover up these jars right away.  Soon, however, I will be wrapping these in some cheap aluminum foil to keep the artificial light from shining into the water and potentially causing algae growth.
