## Abstract

The present invention is an apparatus and associated methods for more efficiently managing factors critical to the efficient production of beneficial plant life. The apparatus in one embodiment is a cylinder filled with a plant growth medium. The cylinder receives seedlings by the use of baskets that are inserted into the external surface of the cylinder. The seedlings are irrigated by fluids received along the axis of the cylinder. The axis of the cylinder is oriented perpendicular to the force of gravity (parallel to the earth's surface) and rotates along the cylinder axis.

## Claims

### Claim 1

An apparatus for growing plants comprising:
a cylinder that is mounted on a fixed hollow perforated axle permitting the cylinder to rotate around said fixed axle;
a mounting stand to support said axle at its ends to hold the cylinder in a substantially horizontal position;
the axle being perforated along its length to allow the passage of liquids introduced to the hollow axle through an end of the axle to pass through the axle to an inner surface of the cylinder;
the inner surface of the cylinder being permeable to the liquids and impermeable to a plant growth medium;
an outer surface of the cylinder being perforated to allow the rooting of plants through the outer surface of the cylinder;
the inner and outer surfaces of the cylinder being held separate from each other by end caps;
an interior space between the inner and outer surfaces of the cylinder being substantially filled with a plant growth medium;
the cylinder being communicably coupled with a drive source that causes the cylinder to rotate.

### Claim 2

An apparatus for growing plants comprising:
a cylinder that is bearing mounted on a fixed hollow perforated axle permitting the cylinder to rotate around said fixed axle;
a mounting stand to support said axle at its ends to hold the cylinder in a substantially horizontal position;
the axle being perforated along its length to allow the passage of liquids introduced to the hollow axle through an end of the axle to pass through the axle to an inner surface of the cylinder;
the inner surface of the cylinder comprising two layers;
the one layer being perforated;
the other layer being a silt sleeve that is permeable to the liquids and impermeable to a plant growth medium;
an outer surface of the cylinder being perforated with holes designed to accommodate insertion and fastening of at least one rooting basket to the outer surface of the cylinder;
the rooting basket designed to contain a plant and fastened to the outer surface of the cylinder by an interlocking fastener;
the inner and outer surfaces of the cylinder being held separate from each other by end caps that form flat end surfaces of the cylinder;
the end caps comprising a central hole with a diameter smaller than that formed by the inner surface of the cylinder and larger than that of the axle such that the load of the cylinder is transferred to the axle by the end caps;
an interior space between the inner and outer surfaces of the cylinder being substantially filled with the plant growth medium;
the cylinder being communicably coupled with a drive source that causes the cylinder to rotate.
