🌱 Growing Cannabis Seeds – Common Questions
💧 How do I soak cannabis seeds before planting?
Place the seeds in a glass of cold tap water or rainwater and keep the glass in a dark place. Wait between 2 and 10 days until the seeds begin to sprout.
🌿 How deep should I plant germinated seeds?
Plant sprouted seeds about 0.5 cm deep in light, moist soil with the root pointing down. Handle gently to avoid damaging the sprout.
💧 How moist should the soil be for seedlings?
Keep the soil evenly moist but never soaked. Overwatering can drown young seedlings. A small propagator helps maintain humidity.
⚠️ What are common mistakes when growing cannabis seeds?
❌ Soil that’s too wet – the seedling may rot.
❌ Planting too deep – the seedling may not reach the surface.
Always ensure good drainage and shallow planting.
🌱 Do I need special soil or pots for growing?
Use seed-raising or herb soil and pots with drainage holes so excess water can escape. This prevents root rot and promotes healthy growth.
