Lights:
As the plants grow a significant amount of height in our system, the lights will have to be dimmed as to not burn out the plants or move to a higher distance.
Foam Cubes:
If the roots of the plants are still not reaching the water below, make sure the foam cubes are saturated with water in order to keep the growth of the seeds.
Strings:
Once the plants grow long enough into the water, the strings may be cut off. The plants might also need to be readjusted in the cups in order for the roots to grow through.
