Blackout Domes and Humidity Domes from Bootstrap Farmer

Blackout domes are primarily used to create a dark environment for seeds or plants that require it for germination or optimal growth. This is particularly common with certain microgreens, where a blackout period encourages taller, more desirable stem growth. They also maintain humidity.

While both types of domes maintain humidity, blackout domes are made from opaque materials that block out light. Regular humidity domes are typically clear, allowing light to penetrate. Therefore, blackout domes provide the additional benefit of light deprivation.

While they are very popular for microgreens, blackout domes can be used for any seeds or plants that benefit from a period of darkness. Some seeds germinate better in darkness, and certain plant propagation techniques may also benefit from it.

Yes, many blackout domes, like those from Bootstrap Farmer, include adjustable vents. This allows you to regulate airflow and humidity, preventing issues like mold growth, even while maintaining darkness.

Yes, good quality blackout domes are designed to block nearly all light. This is essential for plants that require complete darkness. However, it is always wise to ensure that the dome is properly fitted to the tray to prevent light leaks.

Humidity domes are designed to trap moisture and warmth, creating a controlled environment that promotes seed germination. This helps to maintain consistent humidity levels, preventing seeds and seedlings from drying out.

Once seedlings begin to emerge and develop their first true leaves, it's time to start gradually removing the dome. Leaving it on for too long can lead to excessive humidity and fungal diseases like damping-off.

Yes, excessive humidity can create an environment conducive to mold and fungal growth, which can harm or kill seedlings. Proper ventilation is crucial, and many domes have adjustable vents to help regulate airflow.

While many seeds benefit from the increased humidity, not all do. Seeds that prefer drier conditions or larger seeds with ample moisture reserves may not require a dome.

To prevent mold, ensure proper ventilation by adjusting vents or periodically removing the dome. Avoid overwatering, and maintain good hygiene by cleaning your trays and domes regularly. Also, make sure to remove the dome once the seedlings have begun to sprout.
