Jack Flash seeds can be used in indoor or outdoor environments, with growers often adjusting training and pruning techniques to manage height and branching.
As with many photoperiod strains, consistent light cycles, balanced nutrition, and adequate airflow are important for healthy development.

🌱 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.
