A seed and plant growth medium module includes a seed embedded in plant growth medium which is encapsulated in a biodegradable moisture retaining shell. The shell has a bottom with an upper covering. A root opening is provided in the bottom to allow egress of roots as the seed germinates. A plant egress opening is provided in the upper covering to allow upward growth of a plant resulting when the seed germinates. At least one water entry opening is provided in the shell to allow entry of moisture into the shell to wet the plant growth medium.
