FAQ
How is plant count calculated?
Plants = area (㎡) ÷ (row × plant spacing). e.g. 100 pyeong (330.6㎡) at 30cm × 20cm fits about 5,510 plants.
How many seeds?
Total seeds = plants × seeds per plant. Direct sowing sometimes uses 2-3 seeds per spot.
How do I set spacing?
Follow the recommended spacing (row × plant) for your crop, shown on the seed packet or guide.
