  "textContent": "This modular seed starter tray system is designed to help you grow stronger, healthier seedlings using a proven air pruning root method.\nUnlike traditional seed trays where roots circle and weaken, this system encourages roots to grow wider and stronger, creating more resilient plants ready for transplanting.\n🌬️ HOW AIR PRUNING WORKS (KEY BENEFIT)\nAs roots grow downward, they reach the open grid base and come into contact with air.\n✔ Root tips naturally stop growing\n✔ Growth energy is redirected sideways\n✔ New side roots form and spread\n✔ Seedlings develop a dense, strong root structure\nThis process, known as air pruning, is widely used in professional seed propagation systems to produce healthier plants.\n📐 DIMENSIONS\nBase Pallet: 220 × 145 mm\nOuter Growing Tray: 140 × 55 mm\nHeight: 55 mm\nThe modular layout allows flexible arrangements on desks, tables, or greenhouse shelves.\n🧩 DESIGN FEATURES\nClosed side walls to prevent soil loss\nOpen grid base for air pruning and drainage\nRaised base pallet for airflow underneath\nModular design for expandable setups\nClean, functional, and easy-to-print geometry\n🖨️ 3D PRINTING DETAILS\nFile format: STL\nDesigned for FDM 3D printers\nNo supports required\nEasy and reliable to print\nRecommended settings:\nPLA or PETG\n0.2 mm layer height\n10–20% infill\nFor best results, use seed starting soil or coco peat mix.\n📦 WHAT’S INCLUDED\nOuter growing tray\nRemovable air pruning grid insert\nBase pallet\nLabel slot insert\nAll STL files are clearly named by part for easy printing and assembly.\n🏷️ PLANT LABELS (IMPORTANT)\nStandard plant labels are included.\n👉 If you need more labels or different label sizes,\nplease visit my Etsy shop to find the Plant Label STL pack.\n👉 If you would like custom or personalized plant labels\n(with your own text, plant names, or sizes),\nfeel free to contact me via Etsy — I’m happy to help.\n📜 LICENSE INFORMATION\nPERSONAL USE ONLY\n✔ You may print for personal use\n✔ You may print multiple times for yourself\n❌ Commercial use is NOT allowed\n❌ Selling printed parts is NOT allowed\n❌ Sharing or redistributing files is NOT allowed\nCommercial licenses are available separately.\nPlease contact me via Etsy for details.\n⭐ FEEDBACK\nIf you are happy with your print, I would really appreciate it if you leave a review on Etsy.\nYour feedback helps support small creators and future updates.\nHappy growing 🌱\nHappy printing 🖨️",
