The benefit of the Gravity Well thin layer is two-fold. First, plants are just barely in contact with the liquid, so most of the tissues are in atmosphere. Second, the oxygen diffusion into the liquid layer is enhanced because the surface area to volume ratio is very high.

Definitely not! The Gravity Well operates by maintaining a 1mm layer using hydrostatic equilibrium. Media will only leave the reservoir when the layer drops below 1mm.

We can’t say how your particular species will work, but we have tested and had great success with: Artemesia annua, Hemerocallis spp., Drosera spatulata, Saintpaulia spp., Betula lenta and Cannabis sativa. We will be continuing to evaluate the Gravity Well with more species, and publish results from our customers.

Yes, the Gravity Well and We Vitro vessel are completely autoclave safe.
