6 Best Jang Seeders for Market Gardens

You’ve spent hours meticulously preparing a garden bed, only to spend another hour on your hands and knees, painstakingly dropping tiny carrot seeds into a furrow. You hope for the best, but you know the result: patchy germination, wasted seed, and a back-breaking thinning session in a few weeks. This is the moment every small-scale grower realizes there has to be a better way. For thousands of market gardeners and serious hobby farmers, that better way is a Jang seeder.

Why Jang Seeders Dominate Small-Scale Farming

Jang seeders have become the gold standard on small farms for one simple reason: precision. Unlike cheap plate seeders that drop clumps of seeds or skip spots entirely, a Jang uses a system of specialized rollers to pick up and deposit single seeds at a precise, consistent spacing. This means less seed waste, which is a huge cost-saver when you’re buying expensive pelleted or hybrid varieties.

The real magic, however, is the time saved during thinning. When you plant carrots, radishes, or salad turnips at their final spacing from the start, you practically eliminate the tedious chore of thinning seedlings. This single benefit can free up dozens of hours over a season, allowing you to focus on harvesting, marketing, or simply enjoying your farm.

Finally, the versatility is unmatched. With a quick swap of a roller and a simple gear change, the same seeder can plant anything from tiny arugula seeds to larger beet seeds. This adaptability makes it a true workhorse, replacing multiple less effective tools with one reliable, well-built machine that will last for years.

Jang JP-1: The Original Precision Push Seeder

The JP-1 is the seeder that started it all, and for most small growers, it’s the only one they’ll ever need. It’s a single-row push seeder with a simple, robust design that’s easy to understand and maintain. This is the go-to tool for seeding long rows of carrots, beets, radishes, spinach, and dozens of other direct-sown crops.

Its strength lies in its straightforward efficiency. You fill the hopper, set your gears for the desired in-row spacing, and walk. The front wheel firms the soil, the plow opens a furrow, the roller drops the seed, and the rear wheel closes and tamps the soil—all in one smooth pass. It turns a frustrating task into a satisfying and almost meditative one.

If you’re just starting to scale up your production and want to make the single biggest impact on your efficiency, the JP-1 is the investment to make. It’s the foundation of the entire Jang system and provides the perfect balance of precision, versatility, and cost for the vast majority of market garden tasks.

Jang JPH-U: Ergonomic Design for Long Days

The JPH-U is functionally identical to the classic JP-1, but with one crucial difference: its upright, T-shaped handle. While this may seem like a minor change, anyone who has spent a full morning seeding multiple beds will tell you it’s a game-changer for ergonomics.

The standard bent handle of the JP-1 requires you to lean forward slightly, which can put a strain on your lower back over time. The JPH-U’s upright design allows you to walk with a more natural, upright posture, pushing the seeder forward with less effort. This reduces fatigue and makes long seeding days far more comfortable.

Is it worth the extra cost? If you’re seeding more than a few hundred row feet at a time, absolutely. For growers managing a quarter-acre or more of intensive production, the improved ergonomics of the JPH-U can prevent repetitive stress injuries and make the work more sustainable in the long run. It’s a small upgrade that pays big dividends in comfort.

Jang TD-1: Top Choice for Pelleted & Small Seed

While the JP series is a fantastic all-rounder, the TD-1 is a specialist’s tool designed for one thing: perfectly singulating small and pelleted seeds. It uses a different mechanism with a vertical seed plate instead of a horizontal roller, which gives it an edge with tricky seeds like raw lettuce, carrots, or pelleted varieties.

The TD-1 truly shines where absolute precision is non-negotiable. If you’re growing high-value crops like head lettuce and need every seed to be perfectly spaced to ensure uniform, marketable heads, this is your seeder. The design minimizes "doubles" (two seeds dropped at once) and "skips" (no seed dropped), which is critical for crops that don’t get thinned.

The tradeoff is a slightly more involved setup and a higher price point. It’s not the first Jang most people buy, but it’s often the second. For growers specializing in salad greens or those who rely heavily on expensive pelleted seed, the TD-1’s unparalleled accuracy justifies the investment by maximizing germination and producing a more uniform, profitable crop.

Jang JP-2: Perfect for High-Density Double Rows

The Jang JP-2 takes the precision of the original JP-1 and doubles it. This model features two hoppers and two seed-dropping mechanisms on a single frame, allowing you to plant two closely spaced rows in a single pass. This is an incredible time-saver for crops that thrive in high-density plantings.

Think of crops like spinach, scallions, or baby arugula. Instead of making two separate passes down a bed, you can seed both rows at once, perfectly parallel every time. The row spacing on the JP-2 is adjustable, typically from around 2 to 4 inches, which is ideal for creating dense, weed-suppressing stands of greens.

This seeder is perfect for the market gardener who has standardized their bed system. By planting two rows at a time, you not only cut your seeding time in half but also make cultivation easier. A double row of spinach is far easier to weed and harvest than a wide, scattered band of seeds.

Jang JP-3: Triple Your Seeding Speed in Beds

For growers using a 30-inch bed system, the JP-3 is a model of efficiency. As the name suggests, it plants three rows simultaneously. This tool is designed specifically for maximizing the planting density of crops like salad mix, baby kale, or cilantro within a standardized bed.

The JP-3 allows you to seed an entire bed top in just two or three passes, depending on your desired spacing. This dramatically speeds up the planting process for high-volume, quick-turnaround crops. If you’re harvesting and reseeding beds of salad mix weekly, the time savings from a JP-3 quickly add up.

This is a more specialized tool than the JP-1. It’s best for farmers who have committed to a fixed-width bed system and are focused on producing large quantities of densely planted crops. It represents a move from planting single rows to managing the entire bed as a single, productive unit.

Jang JP-5: Maximize Density in 30-Inch Beds

The Jang JP-5 is the ultimate tool for maximum density. With five hoppers on a single toolbar, this seeder is built for blanketing a 30-inch bed with crops like baby leaf lettuce, spicy mixes, or microgreens. In a single pass, you can lay down five perfectly spaced rows, creating a full, lush mat of greens.

This seeder is all about maximizing yield per square foot for cut-and-come-again crops. The ability to quickly and accurately seed five rows at once transforms bed preparation and planting. What would take nearly an hour by hand can be accomplished in just a few minutes, with far better seed spacing and germination.

The JP-5 is not for everyone. It’s a significant investment and is really only practical for commercial growers who are producing high volumes of baby leaf greens for salad mix. For those farmers, however, it is an indispensable tool that makes their entire production system possible. It’s a perfect example of how the right tool can define a farm’s efficiency and profitability.

Choosing the Right Jang Roller for Your Crops

The heart of any Jang seeder is the roller. This small, plastic wheel is engineered with specifically sized and spaced divots that pick up individual seeds from the hopper and drop them down the chute. Choosing the right roller is just as important as choosing the right seeder model.

Jang rollers use a simple code system. A letter indicates the size of the divot (and thus the seed it’s for), and a number indicates the number of divots around the roller’s circumference (which determines spacing). For example:

• An F-12 roller has medium-sized divots (F) and 12 of them. It’s perfect for standard carrot varieties.
• An X-24 roller has larger divots (X) and 24 of them. It’s a common choice for spinach or beets at a tight spacing.
• A YJ-12 has small, shallow divots (YJ) and is ideal for small, pelleted lettuce seeds.

The best approach is to start with a few key rollers for your main crops. Most suppliers have charts that recommend specific rollers for common vegetables. Don’t be afraid to experiment. Sometimes, a slightly larger or smaller divot, or a different spacing, can make a huge difference in germination for a particular seed variety.

Ultimately, you will build a collection of rollers tailored to what you grow. Keep them organized and labeled. Mastering the roller system is what elevates the Jang from a good tool to an essential part of a highly efficient, small-scale farming operation.

Investing in a Jang seeder isn’t just about buying a piece of equipment; it’s about buying back your time and eliminating one of the most frustrating bottlenecks in small-scale farming. Whether you start with the versatile JP-1 or a specialized multi-row model, mastering precision seeding will lead to better crops, less waste, and a more profitable, sustainable farm.
