3. Water and a humidity dome
4. Grow lights and heat mats

Using a dry soil method can make the process easier and cleaner.

1. Fill the seed starting trays with dry potting soil, pressing down lightly to keep it fluffy.
2. Fill the water reservoir of the trays halfway with plain water, allowing it to soak up from the bottom.

Carefully sow the geranium seeds to ensure proper germination.

1. Drop one seed into each cell of the tray.
2. Gently press down the seeds into the soil and cover them lightly with more soil.
3. Place a humidity dome over the trays to retain moisture.

Creating the right environment is crucial for successful germination.

1. Set the trays on heat mats to maintain a temperature of 70 to 75 degrees Fahrenheit.
2. Ensure the trays are under grow lights for at least 12 to 16 hours a day.

Maintain moisture levels and check for germination progress.

1. Keep the humidity dome on until at least 60% of the seeds have germinated.
2. Lift the tray occasionally to refill the water reservoir as needed.

Once seedlings emerge, provide them with the care they need to thrive.

1. Remove the humidity dome and adjust the light source to be about 6 inches above the seedlings.
2. Fertilize the seedlings with a diluted fertilizer once the first true leaves develop.
