🌱 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.
