Plant farms develop their aquatic crops with the leaves out of water to encourage quicker development and decrease algae.

While you purchase an emersed-grown cryptocoryne and put it absolutely underwater, the crypt should transition right into a submersed-grown plant that is accustomed to absorbing mild and CO2 from the water. All of the thick, broad, emersed leaves normally soften away, and smaller, thinner, submersed leaves seem of their stead.
