To Full Size
🌞 Choose a Sunny Spot: Basil thrives in full sun with at least 6 hours of light daily.
🌱 Sow the Seeds: Start indoors 6 weeks before the last frost or direct sow after danger of frost has passed. Plant seeds ¼ inch deep.
💧 Water Gently: Keep soil moist but not soggy. Avoid overhead watering to prevent mildew.
🌾 Thin and Maintain: Thin seedlings to 6–12 inches apart. Pinch off flower buds to encourage leaf growth.
✂️ Harvest: Begin harvesting once plants are 6–8 inches tall. Pick leaves regularly to promote bushier growth.

For Microgreens
🌱 Prepare Your Tray: Use a shallow tray with drainage. Fill with seed-starting mix or coco coir.
🌾 Sow the Seeds: Scatter seeds evenly (8–10 grams per 10"x20" tray). Lightly press into the surface.
💧 Mist and Cover: Mist gently and cover with a humidity dome or tray lid.
🌱 Germination (Days 1–4): Keep in a warm, dark place. Mist daily.
🌞 Light and Watering (Days 5–10): Remove cover and place under grow lights or in a sunny window. Begin bottom watering.
✂️ Harvest (Days 10–14): Cut when microgreens are 2–3 inches tall. Use fresh or store in the fridge for up to a week.
