Rooted in Results: What Real-World Growers See with Maxstim

Greenhouse results: stronger roots, longer harvests

In Ontario, Canada, one of the world’s largest greenhouse hubs, around 40% of growers now use Maxstim. They see:

• Denser, more active root systems
• Better resilience under heat and disease pressure
• Longer picking windows, with healthy fruit into October

The difference is visible: stronger roots, stronger crops.

Potatoes: 36 commercial trials, consistent gains

Across 14 varieties and 36 trials:

• Average 9% yield uplift
• £600–£800/ha more margin
• Improved skin finish, opening access to premium markets

These results are from real commercial fields, not controlled plots.

From scepticism to adoption

Farmers are rightly cautious. That’s why Maxstim trials are run on real farms, side by side with standard practice. Once growers see the proof, they scale up.

As one grower put it:

“I’d only believe it if I saw it in a commercial-scale trial. Now I use it across the board.”
