Our Humidity Domes are an optional component of the Paperpot system, fitting perfectly onto our Paperpot Germination Trays (sold separately) to create the optimum environment for seed germination.

Increase plant growth!

Humidity domes create the perfect might climate for seeds to germinate.   Humidity domes and heat mats can be combined to create the benefits of a germination chamber. 

If you have plants growing slower due to cold temperatures, then you can use the humidity domes to increase temperature and humidity at the tray surface.  This can be a useful strategy for farms with heated or unheated greenhouses.

Our domes are designed to last! 

We produce our domes using thick PET plastic to ensure that they can withstand high greenhouse temperatures and exposure to sunlight.  The domes are resistant to cracking and should give you many years of use.

Need less light?

Humidity Domes can be painted black to create blackout domes for microgreens.
