🌱 MICROGREENS TRAY

Grow fresh, nutritious microgreens at home with this reusable 3D-printed Microgreens Tray. The elevated grid keeps your seeds above the water reservoir, allowing roots to grow through the openings while maintaining excellent moisture levels. This simple hydroponic-style design helps promote healthy growth, reduces the risk of mold, and makes harvesting quick and easy.

Perfect for beginners and experienced growers alike, this tray is designed to be durable, easy to clean, and reusable for countless growing cycles.

How to Use

1. Insert the grid into the tray.
2. Fill the tray with water until it just reaches the underside of the grid.
3. Choose your growing method:
   • Small seeds (broccoli, radish, mustard, basil, arugula, clover, etc.): Place a thin layer of cotton wool (or another suitable growing medium) on top of the grid before spreading the seeds.
   • Large seeds (peas, sunflower, beans, corn, etc.): Place the seeds directly on the grid—no cotton or growing medium is required.
4. Keep the water level consistent so the roots always have access to moisture.
5. During germination, keep the tray in a warm place. Once the seeds have sprouted, move it to a bright location with indirect sunlight or under a grow light.
6. Harvest your microgreens when they reach the desired size, usually 7–10 days after sowing.

Features

• 🌱 Reusable 3D-printed design
• 💧 Separate water reservoir for consistent moisture
• 🧼 Easy to clean and reuse
• ♻️ Printed from environmentally friendly PLA
• 🌿 Suitable for a wide variety of microgreens
• 🏡 Perfect for kitchens, apartments, classrooms, and indoor gardening

Stackable Design

The trays are fully stackable, making storage simple and efficient. You can also stack multiple trays when not in use to save space, making them ideal for growers with several sets.

Recommended Print Settings

For the best performance and a watertight tray, the following print settings are recommended:

• Material: PLA
• Layer Height: 0.20 mm
• Walls / Perimeters: 3–5 (recommended)
• Bottom Layers: 5–8
• Supports: Not required

Using 3–5 wall perimeters creates a strong, durable shell and greatly improves the tray's waterproof performance, minimizing the chance of leaks. Since waterproofing depends primarily on the outer walls rather than the infill, increasing the number of perimeters is more effective than increasing infill percentage.

Tip: If your printer tends to produce tiny gaps between extrusion lines, increasing the wall count or slightly increasing the extrusion flow (around 102–105%) can further improve water resistance.

Enjoy growing fresh, healthy microgreens all year round with this simple, reusable, and space-saving growing system!

🌱 微型蔬菜种植托盘（Microgreens Tray）

使用这款可重复使用的 3D打印微型蔬菜种植托盘，轻松在家种植新鲜、营养丰富的微型蔬菜（Microgreens）。

托盘采用高架网格设计，使种子悬置于储水槽上方，植物根系可穿过网孔向下生长，持续吸收水分，同时保持良好的湿度环境。这种简单的水培式设计有助于促进健康生长、降低发霉风险，并让收获过程更加轻松方便。

无论您是初学者还是经验丰富的种植爱好者，这款托盘都具有坚固耐用、易于清洁、可重复使用等特点，可满足长期种植需求。

使用方法

1. 将网格放入托盘内。
2. 向托盘中加入清水，水位保持在刚好接触网格底部即可。
3. 根据种子的大小选择种植方式：

小颗粒种子（如西兰花、萝卜、芥菜、罗勒、芝麻菜、三叶草等）：

• 先在网格上铺一层薄薄的棉花（或其他适合的育苗基质），再均匀撒上种子。

大颗粒种子（如豌豆、向日葵、豆类、玉米等）：

• 可直接将种子放置在网格上，无需棉花或其他育苗基质。

1. 保持水位稳定，确保根系始终能够接触到水分。
2. 发芽期间，请将托盘放置于温暖环境中。待种子萌发后，再移至光线充足但避免阳光直射的位置，或使用植物补光灯进行照明。
3. 一般播种后约 7–10天，当微型蔬菜长至理想高度即可采收。

产品特点

• 🌱 可重复使用的3D打印设计
• 💧 独立储水槽，持续保持适宜湿度
• 🧼 易于清洗，可长期重复使用
• ♻️ 采用环保PLA材料打印
• 🌿 适用于多种微型蔬菜品种
• 🏡 非常适合家庭厨房、公寓、教室及室内园艺

可堆叠设计

托盘采用可堆叠结构，方便收纳和节省空间。

不使用时，可将多个托盘整齐叠放，非常适合拥有多套种植设备的用户，让储存更加整洁高效。

推荐打印参数

为了获得最佳使用效果以及良好的防水性能，建议采用以下打印参数：

• 材料： PLA
• 层高： 0.20 mm
• 壁厚 / 外壳层数（Walls / Perimeters）： 3–5层（推荐）
• 底层数量： 5–8层
• 支撑： 无需支撑

采用 3–5层外壳 可以形成坚固耐用的结构，并显著提升托盘的防水性能，有效降低漏水的可能性。

由于托盘的防水效果主要取决于外壳的完整性，而不是填充率，因此增加外壳层数通常比提高填充率更加有效。

提示：

如果您的3D打印机容易在挤出线之间产生细小缝隙，可以适当增加外壳层数，或将挤出流量（Flow）提高至约 102%–105%，以进一步提升防水性能。

使用这套简单、可重复使用且节省空间的种植系统，让您一年四季都能轻松种植新鲜、健康的微型蔬菜，随时享受现摘现吃的美味！ 🌱
