Seedling spacing
Every crop comes with a recommended distance between plants and between rows. Some typical figures: tomato 50 cm in row × 80 cm between rows; lettuce 25 × 25 cm; carrot 5 × 20 cm; pumpkin 1 × 2 m; coffee 3 × 1 m. Packing plants closer together raises production per m², but it also brings more disease pressure, since ventilation drops and plants compete for light and nutrients. A quincunx (zigzag) layout fits more in than straight rows do, which is why you see it in orchards and reforestation work. As an example, a 4 m × 5 m bed of lettuce at 25 × 25 cm holds about 320 seedlings.
Applications
It comes in handy for commercial agriculture, home gardens, laying out vertical gardens and raised beds, agroforestry, and reforestation projects. It also gives you a quick estimate of how many seedlings you'll need, whether you're buying them or raising your own in a nursery.
FAQ
Can I plant denser to get more yield? Only up to a point. Push past it and fungi, mites, and the fight for light cut into per-plant yield, so the overall harvest actually drops.
What is intercropping? It's growing two species with different spacing in the same plot, like corn and bean together. They stay out of each other's way because they fill different niches.
Does spacing depend on the cultivar? It does. Determinate tomato (the bush type) can sit closer together than indeterminate (vine) tomato, which needs trellising and more room to spread.

Die Swell Ratio
Calculate the die swell ratio, B = D_extrudate ÷ D_die, from the extrudate diameter once it stabilizes D_extrudate and the die orifice diameter D_die. Die swell is one of extrusion's most characteristic and challenging phenomena: on leaving the die, the molten polymer EXPANDS, ending up larger than the orifice that shaped it (swells of 1.2-2× are common). The cause is the VISCOELASTIC nature of polymers: inside the die, the long molecular chains are compressed and oriented (stretched) by the flow; on exiting and losing confinement, they relax and elastically recoil, like a spring, swelling the material. Swell is greater the more elastic the polymer, the higher the shear rate and the shorter the die (less time to relax inside). It is critical in die design: to make a pipe or profile of the exact target size, the die must be designed SMALLER, anticipating the swell — and since it varies with temperature and speed, controlling swell is essential for dimensional accuracy. Enter the extrudate diameter and the die diameter.
