Here at Hurlstone, we use hydroponic systems to grow fresh produce like lettuce, bok choy, rocket, broccoli and herbs like chives, coriander, parsley and sage!
Hydroponic technology is another sustainable practice in horticulture that involves growing plants in a water medium rather than soil. The water acts as a solvent to deliver minerals to the plants’ roots.
Our trusty Year 7s and Year 8s are the ones in charge of these! They grow them and look after them at lunchtime. After harvesting, they sell it as a business competing with other classes. (see video below for more!)
It’s not all fun and games for the young ones either! It’s very educational – the chemistry behind the hydroponic water solution is part of the Year 12’s learning program.
It is an extremely efficient and sustainable way of growing plants with numerous benefits:
- Allows you to grow all year round
- Allows you to conserve/recycle water
- Allows you to control plants’ nutrient intake
- Better use of space
- Plants grow quicker
- Higher yields
- Eliminates issue of weeds
- Eliminates issue of soil-borne pests → reduces need and cost of pesticides
- Overall less maintenance/labour
The graph shows the increased growth rate of plants grown hydroponically. It’s definitely efficient and sustainable!
