Know before you buy
The X-24 roller features 5/32" (4mm) holes, making it best suited for medium-sized seeds like beets, chard, or similar round seeds that fit comfortably within that diameter.
Seed spacing is controlled by changing the sprocket combination on your Jang JP-1 seeder. By swapping these gears, you can achieve precise intervals ranging from 1/2" to 2.5".
Static electricity can cause small seeds to clump together or stick to the roller, leading to uneven planting. The anti-abrasion, anti-static material ensures seeds flow smoothly and singulate correctly for consistent spacing.
Yes, the X-24 roller is specifically designed to be compatible with the Jang JP-1 precision garden seeder series.
This specific roller is optimized for seeds that fit the 4mm hole size. Very small or flat, irregular seeds may not singulate properly and might require a different roller configuration designed for those specific seed shapes.
