From the page: Styrofoam that turns into creative gold
Idea 1
Windowsill seed starter
Styrofoam trays became a classic seedling nursery among urban gardeners because the material keeps root temperature stable, like a miniature greenhouse. Seeds germinate better with constant warmth, and the root grows strong before transplanting.
What you need
- Styrofoam tray with high edges
- Potting soil or light substrate
- Seeds (lettuce, arugula, kale, tomato)
- Water in a spray bottle
- A heated iron tip or screwdriver (for poking holes)
- Plastic wrap or a clear plastic bag
How to make it
-
1
Poke holes in the bottom of the tray with the heated tip, making small holes about half a centimeter every 2 inches — excess water needs to escape so the root doesn't rot.
-
2
Add a thin layer of damp soil, about 2 inches, without pressing: fluffy substrate lets the radicle (first root) descend easily.
-
3
Spread the seeds on the surface and cover with a thin layer of soil, about twice the thickness of the seed.
-
4
Spray water in a fine mist until moist but not soaked — a strong jet displaces tiny seeds to the corner of the tray.
-
5
Cover with clear plastic to create a greenhouse effect, securing it at the edges: constant humidity speeds up germination.
-
6
Place it near a sunny window, and remove the plastic as soon as the first little leaves appear, to prevent fungus.
Finishing touches
write the name and planting date on popsicle-stick labels or strips of repurposed styrofoam. When the seedlings have 4 leaves, transplant them into pots or a garden bed.
