Seniors great activity, they know how to grow vegetables in a urban garden

What is hydroponics?


Plants grow through a process called photosynthesis, in which they use sunlight and a chemical inside their leaves called chlorophyll to convert carbon dioxide (a gas in the air) and water into glucose (a type of sugar) and oxygen.

Hydroponics is a form of gardening that uses no soil, but instead grows plants in a solution of water and nutrients. A hydroponic system can grow plants and vegetables faster than growing outdoors in soil, and hydroponic systems can be used year-round. Plants grown hydroponically often yield more, require less space and use less water than with conventional gardening. A hydroponic system also can be an ideal solution for apartment dwellers and urbanites who do not have an outdoor gardening plot.

How does hydroponics work?


Hydroponic systems work by allowing minute control over environmental conditions like temperature and pH balance and maximized exposure to nutrients and water. Hydroponics operates under a very simple principle: provide plants exactly what they need when they need it. Hydroponics administer nutrient solutions tailored to the needs of the particular plant being grown. They allow you to control exactly how much light the plants receive and for how long. pH levels can be monitored and adjusted. In a highly customized and controlled environment, plant growth accelerates.

By controlling the environment of the plant, many risk factors are reduced. Plants grown in gardens and fields are introduced to a host of variables that negatively impact their health and growth. Fungus in the soil can spread diseases to plants. Wildlife like rabbits can plunder ripening vegetables from your garden. Pests like locusts can descend on crops and obliterate them in an afternoon. 


Hydroponic systems end the unpredictability of growing plants outdoors and on the earth. Without the mechanical resistance of the soil, seedlings can mature much faster. By eliminating pesticides, hydroponics produce much healthier and high-quality fruits and vegetables. Without obstacles, plants are free to grow vigorously and rapidly.

What can be grown in hydroponics?

The five best plants to grow in a hydroponic system are:
      • Lettuce.
      • Spinach.
      • Strawberries.
      • Bell Peppers.
      • Herbs.


Gardening Made Easy For Seniors

Gardening never gets old, but sometimes the people who enjoy it the most find it challenging to do. While many seniors give up this pastime, there are ways to continue gardening regardless of mobility or strength.

Research shows gardening and regular contact with plants are useful for seniors. Aromatic plants can help to trigger memories in patients with dementia. Exposure to plants can relax hospital patients and speed healing and recovery times.

Gardening can also act as occupational therapy. Pruning, planting, weeding, and watering are physically stimulating and can help to encourage the use of motor skills. And don’t underestimate the psychological well-being gardening offers. Seniors benefit emotionally from having the opportunity to care for something at a time when someone else is caring for them. And the act of gardening reduces stress levels and promotes relaxation.

The physical challenges of gardening may require some modifications. For starters, it may be necessary to seek out adaptive, ergonomic tools designed to be more user-friendly for arthritic or weak hands.
