If you're unsure which one is right for your farm, GEM Silage Products is happy to help you decide based on your region and goals.

How do Thunder Seed hybrids perform as corn seed for silage and feed?

Each variety is bred for both silage and feed performance, with high tonnage potential and digestibility.

When growing Thunder corn seed you can expect strong nutrional value that supports both animal health and efficient weight gains.

What are the pros and cons of corn seed hybrids like these?

Pros: Early maturity, high digestibility, stress tolerance, and strong emergence give you dependable harvests and top-quality silage or feed.

Cons: Some ultra-early varieties may trade a bit of tonnage for speed, though this often pays off in harsher climates or tighter growing windows

Can these corn seed varieties handle Alberta, Saskatchewan and Manitoba’s growing conditions?

Yes, absolutely. These hybrids were selected with prairie producers in mind. With maturity ranges between 70–76 days and strong GDU ratings, they’re well-suited for Western Canada’s shorter seasons and unpredictable weather.

What’s the best planting rate for Thunder Seed corn seed?

The recommended planting rates vary slightly:

  • 4072 and 6370 thrive at medium-high to high rates.
  • 4076 performs best with a medium planting rate.

Planting at the right density is key for optimizing silage tonnage and digestibility.

How do I choose between the three Thunder Seed corn seed options?

It comes down to your needs. If you want early maturity and a fast harvest, go with 4072 or 6370. If digestibility and silage quality are your priority, 4076 is your best bet. 

Still unsure? Contact us! GEM Silage Products’ team can help match you with the best corn seed hybrid for your farm and goals.

Are these seeds suitable for both silage and grazing?

Yes! 

All three Thunder Seed corn seed hybrids can be used for dual purposes, either cut for silage or grazed in the field, giving you flexibility depending on your feeding strategy.
