- Identify specific plant varieties that perform well in hydroponic systems
Not all plant varieties will grow in a hydroponic system. Root crops like carrots and beets, for instance, are more suited for the garden. But herbs, greens, and even strawberries do quite well in the vertical towers.
Understanding what will and will not perform well in the towers saves time and trouble for sure. But there is more to it than just answering the question “Will it grow in a tower?” Knowing what pH the plants desire allows you to pair plants with similar needs in a single system to achieve the maximum yield.
Teach the Teacher
Tools & Materials
- Smart Board or chalkboard
- List of crops that work well with hydroponic systems
- Days to germination
- pH range
- Days to transplant
Introduction (10 minutes)
Begin the lesson with the question “What do you think we can grow in the towers?” Ask Students to suggest varieties that they think might work and respond by explaining whether each one will or will not be viable.
Activity (20 minutes)
Share the list of hydro-happy varieties with the Students and explain each of the considerations including days to germinate, days to transplant, and days to maturity. Work through the list one variety at a time.
Considering the pH target for each plant, have the Students group varieties they would like to grow by pH. Plants that prefer the same target pH can be grown in the same tower system. Use the Smart Board or chalkboard to create groupings of varieties with similar pH requirements.
Discussion (10 minutes)
What vegetable are you most excited to try? Which ones do you not like? Are there any that you haven’t had before?
Assessment (5 minutes)
Use the following questions to assess the Students before and after the lesson. Tally the responses of the group in the Assessment Tracking Log for comparison:
- By a show of hands, how many of you know which plants can be grown in hydroponics and which ones cannot?
- How many of you think you could name one plant that does well in hydroponics and one that does not?
