ABSTRACT:
A collapsible terrarium to be used for maintaining a controlled environment around potted plants and similar objects includes a flexible fluid-impermeable enclosure which has a bottom portion and a top portion, and a support structure which supports the top portion on and upwardly of the bottom portion to bound a compartment therewith. The support structure is collapsible and with it also the enclosure. The enclosure has an access opening through which potted plants can be introduced into and withdrawn from the compartment bounded by the enclosure. The opening is fluid-tightly closeable and, when closed, no fluid interchange takes place between the compartment and the exterior of the enclosure. An aperture, preferably with a one-way valve in it, is provided in the top portion of the enclosure and flowable media, such as herbicides, insecticides or similar agents can be introduced therethrough into the compartment to act on the plants accommodated therein.
