What size hydroponics systems is right for your classroom?
Answer... It depends on a number of things such as budget, goal for hydroponics, number of students, area available, etc. Even with a small budget, there are still some options!
Here are example of small hydroponic systems
Super Simple, Super Small
These systems can be done easily at all grade levels with minimal supplies.
The most basic systems would be a wick system and "Kratky" method.
These systems can be done with less than 1 gallon but are only designed for 1 plant per system.
Good for many students building personal systems
Small and Basic
These systems can be done very easily at a small, medium, and large scale.
Water is oxygenated from an air pump and airstone.
Container sizes 1-2 gallons can hold 3-5 small plants.
Container sizes 2-4 gallons can hold 5-10 small plants.
Good for classroom systems or small group systems.
Good size for experimentation
Floating Raft Hydroponic System
Deep Water Culture Hydroponic System
A little bigger, a little more Complex
These systems take a little more ingenuity but can still be done in small spaces.
They may not grow the biggest plants or be great for fruiting plants, but they can grow!
May require water pumps, valves, hoses and spray nozzles.
Container sizes 2-4 gallons can hold 5-10 small plants
Container sizes 2-4 gallons can hold 2-4 medium plants
Container sizes 3-5 gallons can hold 1 large plants
Good size for optimization and troubleshooting
