In the landless farming system, What plants should I choose?

Lettuce is a good plant to start with in a hydroponic system because it’s easy to care for and grows quickly. It’s a leafy green plant with shallow roots that match its short height.

Grains are another option because they can grow in almost any climate. Some examples of crops include: 

• Corn
• Cotton
• Fruit and tree nuts
• Rice
• Soybeans
• Sugar and sweeteners
• Vegetables and pulses
• Wheat

Crops can be used for many purposes, including: food, livestock feed, textiles and paper, decoration, and fuel.
