6 Best Grain Scales for Market Gardens
Find the best compact grain scale for your market garden. We review 6 models praised by veteran farmers for their accuracy and rugged reliability.
You’ve just spent a good bit of money on a 50-pound sack of premium cover crop seed, a custom blend of vetch, rye, and clover. The seeding rate is 2 pounds per 1,000 square feet, and your main growing block is exactly 2,500 square feet. Eyeballing 5 pounds of that seed is a recipe for waste or a patchy, weed-infested bed next season.

Why Accurate Weight Matters for Market Growers
Precision in farming isn’t just for spreadsheets; it starts with a good scale. For market gardeners, accurate weight is the difference between profit and loss, between a thriving crop and a struggling one. It’s about repeatability and control over your inputs.
When you’re mixing custom chicken feed, consistent protein and mineral levels depend on accurate measurements. A few ounces off in a small batch throws the whole ratio out of whack, impacting egg production or growth rates. The same goes for cover crops—too little seed gives weeds the upper hand, while too much is just broadcasting money onto the ground.
Selling your own saved seed or specialty grains like flint corn requires a certified, or at least a certifiably accurate, scale. Your reputation depends on delivering what you promise. An accurate scale isn’t a luxury; it’s a foundational tool for managing costs, ensuring crop and animal health, and maintaining professional integrity.
Ohaus Scout SPX: Lab-Grade Field Precision
When you need dead-on accuracy every single time, the Ohaus Scout is the benchmark. This is a lab-grade instrument tough enough for the barn. Its most notable feature is its incredibly fast stabilization time—you get a stable reading in one second, which is a huge time-saver when you’re weighing out dozens of small seed packets.
The Scout is built with superior overload protection, meaning an accidental drop of a heavy scoop won’t destroy the sensitive load cell. This is the kind of detail that justifies its higher price tag. It’s an investment in avoiding costly mistakes, whether you’re measuring expensive inoculants or high-value specialty seeds.
Of course, the primary tradeoff is cost. This isn’t the scale you buy on a whim. It’s for the grower who has moved beyond casual measurement and requires verifiable precision for their business operations. If your farm’s profitability hinges on precise formulations, the Ohaus Scout pays for itself in reliability.
MyWeigh KD-8000: The All-Purpose Bench Scale
Measure ingredients with precision using the My Weigh KD-8000 digital food scale. Its durable stainless steel platform and accurate readings make baking and cooking easier.
The MyWeigh KD-8000 is the workhorse of the farm bench. It hits the sweet spot between capacity, precision, and price, making it one of the most versatile scales for a small farm. With a capacity of up to 8,000 grams (about 17.6 pounds), it can handle everything from a few ounces of beet seed to a hefty scoop of scratch grains.
One of its best features is the percentage weighing function. This allows you to create feed rations by ratio without doing any math. Just weigh your main ingredient, hit the percent key to set it as 100%, and then add other ingredients until you reach their target percentages. It’s a simple feature that streamlines a common, repetitive task.
The large, removable stainless steel platform is easy to clean, a crucial feature in a dusty or messy environment. While it doesn’t have the wash-down rating of more expensive models, it’s durable enough for the daily rigors of a potting shed or feed room. It’s the perfect all-rounder for a grower who needs one scale to do almost everything.
AWS-100 Pocket Scale for Seeds and Small Lots
Don’t let its small size fool you; a good pocket scale is indispensable. The AWS-100 and similar models are designed for weighing very small quantities with high precision, typically down to 0.01 grams. This is the tool you need for dividing up a packet of 500 expensive tomato seeds or measuring out yeast for brewing.
Its primary advantage is portability. You can carry it right to your seed storage, measure what you need, and not worry about spilling tiny seeds on a trip to the bench. The protective cover doubles as a weighing tray, perfect for keeping things contained.
The key is knowing its limits. This is a specialist’s tool. Attempting to weigh a pound of anything on a pocket scale is an exercise in frustration. It’s for grams, not pounds. For the market gardener who saves and sells their own seed, a pocket scale isn’t optional—it’s essential.
Brecknell 335: A Classic Hanging Scale Design
Sometimes the old ways are the best ways, especially when electronics and dusty barns don’t mix. The Brecknell 335 is a classic mechanical hanging scale, also known as a dial-o-gram or spring scale. With no batteries to die and no circuits to fry, its rugged simplicity is its greatest strength.
This type of scale excels at weighing bulky items in sacks or buckets. You simply hang your container from the hook, fill it to the desired weight, and you’re done. It’s the perfect tool for measuring out 25 pounds of feed for your pigs or portioning bulk compost into bags for sale.
The tradeoff is precision. You won’t be measuring to the tenth of a gram here. Reading a dial can be subjective, and the resolution is much lower than a digital scale. But for bulk tasks where being within a half-pound is good enough, a mechanical hanging scale is more durable and often more practical than a digital counterpart.
Ohaus Valor 1000 for Wash-Down Durability
The farm is a wet, messy place. Whether you’re in the wash station cleaning carrots or mixing a wet mash for your poultry, moisture is the enemy of most electronics. The Ohaus Valor 1000 is built specifically for these environments, with a sealed housing and a rating that allows it to be hosed down for cleaning.
This scale is designed for the food service industry, which means it’s built to last. The stainless steel pan resists corrosion, and the entire unit is designed to prevent water from getting into the sensitive components. This durability means you won’t be buying a new scale every year after the old one gets splashed one too many times.
Investing in a wash-down scale is a strategic decision. If your workflow involves weighing items post-harvest and pre-packing, the Valor 1000 is a smart choice. It costs more than a standard kitchen scale, but it’s far cheaper than replacing three or four less-durable scales that weren’t built for the job.
Escali Primo: Simple, Reliable Countertop Weighing
Sometimes you just need a scale that works without any fuss. The Escali Primo is a popular kitchen scale, but its simplicity, reliability, and affordability make it a fantastic choice for the market garden. It features a simple two-button operation—one for on/off/tare and one to switch units—making it incredibly intuitive to use.
The sealed display and controls mean that a little dirt or a splash of water won’t kill it. While it’s not a true wash-down scale, it’s more resilient than many of its competitors in the same price range. It’s the perfect scale to keep in the office for weighing mail or on the potting bench for quick seed measurements.
With a capacity of around 11 pounds, it handles most daily tasks with ease. It’s not the tool for weighing a 50-pound sack of anything, but for portioning out amendments for potting mix or weighing daily harvests, the Escali Primo offers exceptional value and performance. It’s a testament to the idea that a tool doesn’t need to be complicated to be effective.
Key Features: Tare, Calibration, and Power Source
No matter which scale you choose, three features are non-negotiable. The first is the Tare function. This allows you to place a container on the scale and reset the display to zero, so you’re only weighing the contents. Without it, you’re stuck doing annoying mental math for every single measurement.
Next is Calibration. Over time and with temperature changes, even the best scales can drift. The ability to recalibrate your scale using a known weight ensures its long-term accuracy. Cheaper scales often lack this feature, essentially making them disposable once they lose their accuracy. A good scale is an instrument you can trust, and calibration is the key to that trust.
Finally, consider the Power Source. A scale that only runs on batteries will inevitably die right when you need it most. For a bench scale, an AC adapter is a must-have feature for reliability. For portable scales, look for a model with a long battery life and an auto-off function to conserve power.
Ultimately, the best scale is the one that fits the task at hand. You wouldn’t use a sledgehammer to drive a thumbtack, and you shouldn’t use a high-capacity bench scale to weigh a pinch of lettuce seed. By matching the right tool to the job—a pocket scale for precision, a bench scale for rations, and a hanging scale for bulk—you’ll improve your accuracy, reduce waste, and run a more efficient and profitable market garden.
