How to Use Your Seed Starter Kit

1. Prepare Growing Medium: Fill cells with seed starting mix, rockwool cubes, peat pellets, or your preferred medium
2. Plant Seeds: Sow seeds according to packet directions (typically 2-3 seeds per cell)
3. Water Gently: Moisten the growing medium thoroughly but avoid oversaturation
4. Cover with Dome: Place the humidity dome over the tray to create a warm, humid environment
5. Adjust Vents: Start with vents closed, then gradually open as seedlings emerge to prevent damping off
6. Provide Light: Place under grow lights or in a bright location (avoid direct hot sun under dome)
7. Monitor Conditions: Maintain 70-80°F temperature and 50-60% humidity for most seedlings
8. Transplant: When seedlings develop 2-4 true leaves, transplant to larger containers or garden

Optimal Growing Conditions

• Temperature: 70-80°F for most seedlings and clones
• Humidity: 50-60% (adjustable via dome vents)
• Light: 12-16 hours of light daily for seedlings
• Airflow: Gradually increase ventilation as seedlings grow to strengthen stems

Note: Temperature and humidity requirements vary by plant species. Research your specific plants for best results.

Why Extra-Strength Matters

Unlike cheap, flimsy seed trays that crack and break after one season, our extra-strength construction ensures reliable performance year after year. The heavy-duty plastic won't warp, crack, or become brittle with repeated use and cleaning. This means better value and less waste - invest once and use for many growing seasons.

Professional Humidity Control

The 2" tall humidity dome provides superior headroom compared to shorter domes, allowing seedlings more growing space before transplanting. Built-in adjustable vents give you precise control over humidity and airflow, essential for preventing damping off disease and strengthening seedling stems.

This versatile kit works with all popular growing media:

• Seed Starting Mix: Lightweight, sterile mix ideal for most seeds - try FoxFarm Happy Frog Potting Soil
• Rockwool Cubes: Perfect for hydroponic systems - use Grodan Rockwool
• Peat Pellets: Convenient, expandable growing medium
• Coco Coir: Sustainable, moisture-retentive option
• Vermiculite/Perlite Mix: Excellent drainage for sensitive seeds
