6 Best Airtight Storage Totes For Seed Saving That Old Farmers Swear By
Learn from seasoned farmers. We reveal the 6 best airtight totes they use to protect seed viability, ensuring your saved seeds are ready for planting.
You’ve spent an entire season coaxing the perfect tomato from seed to fruit, and now you hold its future in the palm of your hand. Saving seeds is one of the most rewarding parts of farming, a direct link from one year’s success to the next. But all that work can be undone in a single damp winter if those seeds aren’t stored correctly.

Why Airtight Storage Matters for Seed Viability
Moisture is the number one killer of saved seeds. Even a small amount of humidity can trigger mold, rot, or encourage your seeds to break dormancy at the wrong time, exhausting their energy before they ever see soil. An airtight seal is your first and best defense against this silent threat.
A good gasket doesn’t just keep moisture out; it keeps pests out, too. Weevils, mice, and other critters see your carefully saved seed collection as a free buffet. A securely latched, airtight container makes it nearly impossible for them to get in, protecting your future harvest from being eaten in the shed.
Finally, a sealed environment creates a stable microclimate. It buffers the seeds from the wild temperature and humidity swings that happen in a barn, garage, or basement. This stability is key to keeping seeds dormant and viable for years, not just months.
MTM Ammo Crate: The Time-Tested Farmer’s Choice
There’s a reason you see old-timers using military-surplus ammo cans for everything. They are built to be brutally tough and, most importantly, they have a rubber O-ring gasket that creates a fantastic waterproof seal. The MTM Ammo Crate is a modern, lightweight polymer version of this classic design.
These crates are perfect for organizing your collection. You can dedicate one crate to tomatoes, another to peppers, and a third to beans, stacking them neatly on a shelf. Their smaller size prevents you from just dumping everything into one giant tote where it can get lost or mixed up.
The heavy-duty latch and solid construction mean you don’t have to worry about it popping open if it gets knocked off a shelf. This is the go-to choice for reliability and long-term protection. It’s a simple, effective tool that just plain works, year after year.
Gamma2 Seal Lid: Turn Buckets into Seed Vaults
Every farm has a stack of 5-gallon buckets somewhere. They’re useful for everything, but their standard snap-on lids are far from airtight. The Gamma2 Seal Lid is a brilliant invention that transforms a cheap bucket into a serious, moisture-proof storage vault.
The system is simple: a threaded ring snaps permanently onto the rim of the bucket, and a separate, gasketed lid screws into it. This creates a truly airtight and watertight seal that is easy to open and close repeatedly. No more prying off stubborn lids with a screwdriver.
This is the ideal solution for storing larger quantities of seed, like a few pounds of saved pinto beans, a big batch of sunflower seeds for next year’s oil, or your favorite open-pollinated corn. It’s a cost-effective way to get high-capacity, high-performance storage by upgrading something you already own.
Pelican Protector Case: For Your Most Valuable Seeds
When you have seeds that are truly irreplaceable, you need an insurance policy. That’s what a Pelican case is. These cases are trusted to protect thousands of dollars worth of camera gear and scientific equipment in the harshest environments on earth, and they’ll do the same for your most precious seeds.
They are crushproof, dustproof, and fully submersible. The combination of a heavy-duty polymer shell, a robust O-ring seal, and dual-throw latches creates an impenetrable fortress for your seeds. An automatic pressure equalization valve even accounts for changes in altitude or temperature.
Let’s be honest: this is overkill for your common zucchini seeds. But for that rare heirloom tomato variety passed down through your family, or seeds from a plant you spent years adapting to your specific climate? The peace of mind a Pelican case provides is worth every penny.
IRIS USA WeatherPro: Reliable Gasket-Sealed Totes
If you’re looking for a more conventional storage tote, the IRIS WeatherPro line is a major step up from the cheap, flimsy bins you find everywhere. The key difference is the foam gasket built into the lid and the six sturdy latches that clamp it down. This design creates a reliable seal against moisture, dust, and pests.
These totes come in a wide range of sizes, from shoebox-sized containers perfect for seed packets to large 74-quart trunks. The clear plastic body allows you to see the contents at a glance, which can be helpful for quick inventory checks.
The tradeoff for that visibility is light exposure, which can degrade seeds over time. This isn’t a dealbreaker; it just means you have to commit to storing them in a dark closet, basement, or cabinet. For a dependable, all-around storage solution that balances features and cost, these are hard to beat.
Sterilite Gasket Box: A Budget-Friendly Workhorse
Not every seed in your collection needs maximum-security storage. For your everyday, easy-to-grow staples, the Sterilite Gasket Box is a fantastic, budget-friendly option. You can find them almost anywhere, and they provide a surprisingly good seal for the price.
Like the more expensive IRIS totes, these feature a foam gasket and latching lid. While the plastic is thinner and the latches aren’t as robust as premium options, they are more than capable of keeping ambient humidity and pests out of your seeds in a controlled environment like a basement or closet.
This is the perfect entry-level choice for new seed savers. It allows you to get organized and protect your seeds properly without a big initial investment. Just be realistic—they won’t survive a flood or being run over by a tractor, but for basic protection, they are an excellent value.
Plano Sportsman’s Trunk: For Serious Bulk Storage
When you move from saving packets to saving pounds, you need a different class of container. The Plano Sportsman’s Trunk is designed for hauling gear, but its large capacity and weather-resistant design make it perfect for bulk seed storage. Think bags of cover crop seed, dent corn, or winter rye.
These trunks are rugged, stackable, and often feature wheels, which is a lifesaver when you’re moving 50 pounds of seed around. While the seal isn’t as perfectly airtight as a Pelican case, it’s more than sufficient to protect large seed bags from moisture and rodents in a barn or shed.
This isn’t for meticulously organizing tiny packets. This is your workhorse container for the big stuff. It’s about protecting a significant volume of seed from the primary threats in a larger storage area, ensuring your bulk supplies are clean, dry, and ready for planting.
Beyond the Tote: Labeling and Desiccant Tips
A great container is only half the battle. If you don’t label your seeds properly, you might as well have not saved them at all. At a minimum, every packet or jar inside your tote should be clearly marked with the plant variety and the year it was harvested. Use a paint pen or an industrial marker; standard ink can fade or run if any moisture gets in.
For an extra layer of security, toss a few desiccant packs into your airtight container. These are the little silica gel packets you find in new shoes or electronics, and they are brilliant at absorbing any residual moisture that was sealed in with your seeds. You can buy them cheaply online and "recharge" them in a low oven to be used year after year.
Don’t just rely on the tote’s seal alone. The combination of a dry seed, a clear label, a desiccant pack, and an airtight container is the four-part system that guarantees your seeds will be ready to perform when you are.
Ultimately, the best storage tote is the one that matches the scale and value of your seed collection. Investing in a good container isn’t an expense; it’s a down payment on next year’s garden. It protects the incredible amount of work, patience, and hope that you’ve packed into each and every seed.
