SproutShield – Greenhouse Cap for Seedlings

🌱 Protect your seedlings from cold, wind, and harsh weather — with a simple 3D-printed greenhouse cap made from transparent PETG.

This low-profile dome creates a miniature greenhouse effect directly over your young plants. The warmth is trapped inside, humidity stays elevated, and your seedlings thrive weeks earlier than they would outdoors unprotected.

✅ Greenhouse effect — traps warmth and humidity for faster, healthier germination and early growth
✅ Wind-proof design — the cap is gently pressed into the soil, anchoring it firmly even in strong gusts
✅ UV-stable transparent PETG — lets sunlight through while protecting from frost and cold snaps
✅ Reusable season after season — no more disposable plastic bottles or cling wrap hacks
✅ Lightweight & stackable — easy to store, easy to transport to the garden bed
✅ Open top hole — allows passive airflow to prevent overheating on sunny days

Perfect for raised beds, garden patches, balcony planters, and window-sill seedling trays. Whether you're growing tomatoes, peppers, herbs, or flowers — SproutShield gives every seedling the best possible start.

Simply place it over your seedling and push the rim lightly into the soil. That's it. 

No tools, no clips, no extra hardware needed.

Print in transparent or natural PETG for best results. 0.2mm layer height recommended for a smooth, clear finish. No supports needed.
