Humidity Domes
Provide the perfect environment for germination by covering your flat with a plastic dome that helps retain moisture and warmth. Remove the dome once the seeds emerge to reduce the risk of disease. Use in conjunction with a heat mat for faster, more uniform germination of heat-loving crops. Choose from our durable clear plastic humidity domes and our propagation domes.
