Mondi 1020, 7" Nano Dome w/ Vents (x2)

Details:

The Mondi 7" dome will fit over any 1020 tray. Along with two vents, this dome allows for control over your humidity levels during early propagation. 

It is key to keep your humidity in check during the seedling stage. Too moist and your seedlings can damp off and die. Too dry and transporation rates increase drastically, putting your seedings in danger of drying out, crisping up, and/or taking too many nutrients from the soil too quickly.
