A device for continuous release of a fluid at a near-optimum rate, the device including: a reservoir, having dimensions such that the fluid disposed in the reservoir is held in a shape having a height to a width ratio whereby the width is greater than the height; a flow-rate regulator adapted to regulate fluid release rate of the fluid exiting the reservoir via the flow-rate regulator.

Containers for transporting plants are provided that can include a base having a base recess for receiving a plant and a growing medium or soil, a lid that can attach to the base such that the lid can extend over and enclose the plant within the container, a cover for holding the plant within the base recess that can be mounted within a base opening into the base recess and abutting against the growing medium or soil, at least one light source mounted to an upper surface of the cover, and a tamper-resistant attachment mechanism for attaching the lid and the base together. Methods for enclosing and transporting plants within containers are also provided.

Disclosed is a system having a base and a screened enclosure for disposition on the ground for growing plants. The base forms a hollow enclosure into which a growing medium can be disposed. The screened enclosure is mounted on the base and is in the form of a plurality of elongated frame members, plural upper screen members and plural lower screen members. Each of the screen members has an opposed pair of side edges, a top edge and a bottom edge. The frame members extend upward from the base and are spaced apart from one another. Each of the frame members includes a first respective section arranged to slidably receive a respective side of a respective lower screen member therein and a second respective section arranged to slidably receive a respective side of a respective upper screen member therein. Each of the upper and lower screen members are arranged to be individually removed from their respective sections of their associated frame members to enable each of the screen members to be individually removed from the frame members.

A membrane for covering the cut end of a tree trunk to prevent the tree from creating a seal after it has been cut. The membrane is attachable to the cut end surface of the tree trunk and includes a hydrating layer comprising a hydrogel. The hydrogel, made up primarily of water, adheres to the cut end surface of the tree trunk to continue hydrating the tree, and prevents air from reaching the tree's exposed transport tissue. In some embodiments, the membrane includes a backing layer and a release layer on opposite sides of the hydrating layer.
