Humidity domes are a popular accessory for seed starting and plant propagation, but are they really necessary? Let’s take a look at the pros and cons of using humidity domes to help you decide if they’re worth the investment.
Pros of Using Humidity Domes
Improved germination rates: Humidity domes help maintain high humidity levels, which can improve germination rates for many types of seeds.
Faster seedling growth: The increased humidity under the dome can lead to faster growth and development of seedlings.
Versatile fit: Many humidity domes, like the Bootstrap Farmer 6″ Tall Extra Strength Domes, are designed to fit perfectly on standard 1020 trays and other 10×20 flats.
Durable construction: These domes are made from high-quality, BPA-free clear plastic that is built to last multiple seasons.
Cons of Using Humidity Domes
Potential for mold growth: If humidity levels are not properly managed, humidity domes can create an environment that is ideal for mold growth.
Increased watering needs: Plants under humidity domes may require more frequent watering to prevent the soil from drying out.
Potential for leggy seedlings: If seedlings are kept under the dome for too long or if light levels are insufficient, they may become tall and spindly (leggy).
Cost: While not prohibitively expensive, humidity domes do represent an additional cost for seed starting and propagation.
So, are humidity domes worth it? For many gardeners and growers, the benefits of improved germination rates and faster seedling growth outweigh the potential drawbacks. However, it’s important to carefully monitor humidity levels and ventilation to prevent issues like mold growth or leggy seedlings. With proper management, humidity domes can be a valuable tool for successful seed starting and plant propagation.
