Containers of plants can also be moved to and from
the growing area using gravity conveyors, if proper
STANDARDIZE CONTAINERS,
MIXES, AND METHODS
Many sizes of flats and pots are used in the bedding
plant industry. Most sizes are made by several
manufacturers using slightly different materials and
molds. Because of the large selection, development
of equipment for the industry has been slow. Several
trade associations and the Nursery-Greenhouse
Mechanization Committee of the American Society
of Agricultural Engineers are attempting to develop
standard container sizes that may be adopted by the
industry. Limit the number of container sizes and
types to reduce inventory and time spent making
changes in equipment to accommodate different
containers.
Where possible, limit the number of growing mixes
used. Bin shapes and construction and conveyor
equipment may have to be changed to get materials
flowing freely. Each mix has its own angle of repose.
Bridging of the mix in bins is more common where
materials such as peat, sawdust, and wood chips are
used. Vibrators or agitators may be needed to get the
mix to flow.
