Conserving Water when you Work in a Greenhouse

Water is the source of life in a greenhouse. For the United Nations World Water Day, we are sharing some of the ways our greenhouse is taking steps to protect our precious water resources. Our greenhouses save thousands of litres of fresh-water each month by recycling water and collecting rainwater. 

Rainwater Collection.

Each greenhouse has a special reservoir that collects rainwater, which we use to water our plants with! The reservoirs vary in size depending on the watering needs of that particular location. Most of our greenhouses are located on the "Rainy West Coast" of Canada, which means that we have the opportunity to use a lot of rainwater instead of city water. 

Rainwater is great for our plants because it is fresh and natural.

Watering the Plants.

A lot of water can be wasted if it does not reach the roots of a plant. Sprinklers and "overhead" watering end up wasting water that doesn't reach the soil and the roots. For some plants overhead watering can damage the delicate flowers or even cause moldy berries.

Our greenhouses have special floors that are designed to retain water and allow the plant roots to soak up what each individual plant needs. These floors water the roots of the plants directly instead of the tops of the plant/soil.

Another way we can water the roots of a plant directly is by using drip irrigation lines. These are basically special hoses with attachments that are connected to a spike inserted in the dirt of each potted plant. The hose feeds water to each plant using a drip system so the roots have time to absorb the water. We use this technique with our larger crops and hanging baskets.

Watering the Right Amount at the Right Time.

Plants need varying amounts of water to be happy! Did you know that too much water can be just as harmful as not enough water? If plants are watered too much, their roots can “suffocate” from the lack of oxygen! This is known as root-rot, which can be identified when an unhappy plant has very damp/heavy soil and the roots turn brown.


Our growers are experts at using our water efficiently to avoid waste and keep our plants happy!

Water Recycling Systems.

Most of our greenhouses are designed with some kind of trough or collection system that captures any run-off water the plants don’t absorb. We collect the used and dirty water, then filter it ourselves so that it can be recycled and re-used for the same plants.

Water-Conscious Office Space.

Our offices are equipped with water-efficient appliances and motion-sensing taps.


The amount of water wasted in the production of single-use bottles, plates, and cups is astronomical. To reduce the number of plastic bottles being used, and the number of cups being washed, the company provided water bottles to each employee and installed a water filter. Our office also has a full-sized kitchen with stoves to allow employees to cook meals rather than bring in take-out. Using the provided dishes and dishwasher is another way we reduce waste and water consumption. 

What Now?

There are small things you can do each day that add up to a big difference! 


Here are a few tips:

  • Water your plants with repurposed water or collected rainwater.
  • Skip the Rinse on your dishes when loading them into the dishwasher.
  • Cut your grass around 2 inches tall.
  • Water plants only when needed in mornings or evenings.
  • Use water responsibly: take shorter showers, turn off the taps, check for leaks in your home regularly, and install water efficient appliances.
  • Be a part of the conversation! What does water mean to you?


Thank you for reading today! We hope you have learned something and will join us in the preservation of the Earth’s precious fresh water.

There are many things every one of us can do to reduce water-waste, but we hope that knowing bigger facilities like our greenhouses are doing their part will inspire you to create an environmentally-aware workplace and home.
