How deep should I plant my cannabis seeds?
The answer to this question is simple; just enough to cover the seed. The reason for this is that when you plant a seed too deep, it cannot reach the surface and will die. Soil temperature is also important for germinating marijuana. You want to make sure that your soil temperature is between 65-75 degrees Fahrenheit (18-24 degrees Celsius), but no warmer than 80 degrees Fahrenheit (27 degrees Celsius).
