Is growing your own food actually more sustainable?

Research suggests shorter supply chains and reduced packaging are sustainability advantages of home growing, though outcomes vary by method, scale, and what's being compared.

What does research say about home growing's environmental impact?

Studies comparing microgreens cultivation methods have found that compost-based, distributed growing (like home setups) can be a lower-input alternative to industrial hydroponic greenhouse production.

Are microgreens better for the environment than mature vegetables?

This depends on the comparison; microgreens have a shorter growing cycle and smaller footprint per grow, but a direct environmental comparison depends on growing method and conditions.

What growing method is considered more sustainable, hydroponic or compost-based?

Some research has found that compost-based methods accessible to everyday growers can be a favorable alternative to industrial hydroponic greenhouse production, though both approaches have trade-offs.

FAQ

"Growing your own is better for the environment" is a common claim, but the research behind it is more nuanced than a single headline. Here's what studies on microgreens cultivation methods have actually found.

Sustainability isn't just about growing something yourself, it's about how, and research is actively comparing methods to find out what actually helps.

1. What the Research Actually Compares

Research in Frontiers in Sustainable Food Systems has compared mineral concentration and cultivation approach between hydroponic and compost-based microgreens growing, methods easily implemented by the average home grower, finding support for distributed, compost-based growing over industrial greenhouse hydroponic production.¹

2. Water Use and Growing Method

Separate research has specifically studied irrigation management in microgreens cultivation, since water consumption is considered a critical factor when assessing the environmental impact of any cropping method.¹

Pro Tip

A spray bottle for misting, rather than flooding a tray, is a simple way to reduce water use at home.

3. Supply Chains and Packaging

Beyond the growing method itself, home growing generally shortens the supply chain and cuts out the plastic packaging that store-bought greens typically come in, both commonly cited as sustainability advantages.

What does research say about home growing's impact?

Studies comparing methods found compost-based home growing can be a lower-input alternative to industrial hydroponics.

Does growing microgreens use a lot of water?

It varies by method; research specifically studies irrigation management as a sustainability factor.

Are microgreens more sustainable than mature vegetables?

This depends on the comparison and growing method used.

Hydroponic or compost-based, which is better?

Some research favors compost-based methods accessible to home growers, though both have trade-offs.
