What Exactly Are Microgreen Growing Trays?

Microgreen growing trays are specially designed containers that create the perfect environment for your greens to thrive. They’re not just any planting trays—these are shallow, often equipped with drainage holes, and tailored for quick-growing crops like microgreens. Whether you’re using soil, coco coir, or a hydroponic setup, these trays are essential.

Types of Microgreen Growing Trays

• Plastic trays: These are lightweight, easy to clean, and pretty affordable. Just make sure you pick high-quality, BPA-free ones to avoid any cracks or wear and tear.
• Biodegradable trays: If you’re all about sustainability, biodegradable trays made from recycled materials are a fantastic eco-friendly option. They’re great for the planet but need a bit of extra care since they’re not reusable.
• Metal trays: For those who want something durable, metal trays are a solid pick. They last longer, look sleek, and are great for regular growers, though they’re heavier and pricier.
• Custom trays: These are tailored to specific microgreen varieties or growing setups. These often come with cool features like self-watering systems.

Key Features to Look For

• Good drainage: Choosing the right tray is all about the details. Make sure it has a good drainage system to prevent soggy roots and waterlogging.
• Shallow depth: Shallow trays—around 1-2 inches deep—are perfect for microgreens since they don’t need a lot of space to grow.
• Durable materials: Go for trays made with sturdy, non-toxic materials so you don’t have to worry about harmful chemicals.
• Space-saving designs: If you’re short on space, stackable trays are a lifesaver and make growing multiple batches a breeze.

How to Set Up Your Microgreen Growing Trays

• Preparation: Getting your trays ready is easier than you think. Start by cleaning and sterilizing them to keep pests and diseases at bay.
• Adding a growing medium: Afterward, layer your chosen growing medium—whether it’s soil, coco coir, or a hydroponic mat. Make sure to spread it evenly, forming a smooth and level foundation for your seeds.
• Planting the seeds: Sprinkle your seeds across the surface, but don’t overdo it; crowding can stunt growth.
• Watering and covering: Lightly spray them with water and cover the tray with a humidity dome or plastic wrap to maintain consistent moisture levels.
• Lighting: Place your tray under grow lights or near a sunny window, giving your greens 12-16 hours of light daily. Watch them sprout!

Tips for Maintaining Your Trays

• Regular cleaning: Keeping your trays in good shape means they’ll last longer and give you better results. After every harvest, clean them with warm soapy water and give them a quick sterilization.
• Mold prevention: Proper airflow and watering are key to avoiding mold—don’t let your greens sit in water or stay too damp.
• Replacing old trays: If your trays start to show cracks or wear, it’s time to replace them to keep your greens healthy and happy.

DIY or Store-Bought Trays?

• DIY trays: Thinking of making your own trays? DIY trays are super budget-friendly and allow you to customize them for your specific needs.
• Store-bought trays: On the flip side, store-bought trays are designed specifically for microgreens, so they’re reliable and ready to use. If you’re new to growing or want consistent results, store-bought trays are probably the way to go.

Brands That Get the Job Done

• Bootstrap Farmer: This brand is a favorite for heavy-duty, BPA-free trays that last.
• True Leaf Market: Another great option, offering affordable trays for both beginners and pros.
• Gardener’s Supply Company: If you’re looking for high-quality metal or eco-friendly trays, this brand has you covered.
