Seed Spa Propagator - Medium

The vents are typically sliding mechanisms on the lid. Gently slide them to open or close, controlling the amount of airflow into and out of the propagator.

Yes, you can use it without a heat mat, especially for seeds that germinate at room temperature. However, for species requiring warmer soil temperatures, a heat mat is highly recommended for optimal germination.

The Medium propagator is designed to accommodate most standard-sized seed trays and starter pots commonly available.

Water when the soil surface begins to look dry. The controlled environment helps retain moisture, so you may need to water less frequently than with open trays. Always water gently to avoid disturbing young seedlings.

Once your seeds have germinated and true leaves begin to appear, you can gradually open the vents more to start acclimatizing the seedlings to normal room conditions and reduce humidity.

Clean with warm water and mild dish soap. Rinse thoroughly and ensure it is completely dry before storing or reusing.

Ensure consistent moisture and adequate temperature. Consider using a heated mat if your seeds require higher temperatures for germination. Check that the lid vents are not overly open, maintaining sufficient humidity.

Open the adjustable vents further to increase airflow and reduce humidity inside the propagator. Wipe down excess condensation with a clean cloth.

Ensure the seedlings are receiving adequate light. If using a windowsill, rotate the propagator. If using grow lights, adjust their height and duration. Gradually reduce humidity once seedlings have emerged.

Improve air circulation by opening vents. Remove affected seedlings or soil. Clean the propagator thoroughly with warm soapy water, rinse, and dry before re-using.
