Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.
When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.
When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.
The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.
If there are unsprouted seeds, use a spray bottle (plant mister) to give them a precision dose of water to keep the soil moist after removing the dome.
However, the story changes after your seeds germinate. Seedlings do need light to grow, and they will find it in any way they can.
Do You Need Light To Germinate Seeds In A Humidity Dome?
First, put some soil in your tray. Leave space at the top for watering, or else the water will spill out.
However, a humidity dome has several benefits when starting seeds, including:
This is a real life-saver (or plant saver) when you want to help your seedlings to acclimate to the environment outside of the dome. It also helps to prevent seedlings from getting too hot under the dome.
