The last two decades have seen rapid advances in the technology
used to produce pot plants. Glasshouses designed and orientated to
give maximum light transmission, fully automatic heating and
ventilating systems, carbon dioxide enrichment of the atmosphere,
controlled photoperiods using automatic blackouts and incandescent
lamps which enable plants such as chrysanthemum to be flowered at
any time of the year, mist propagation techniques, chemical growth
regulators which control the height of plants, automatic watering
and feeding systems, etc.: these are only some of the developments
which have transformed pot plant culture. There have also been many
changes in the composts and systems used to grow the plants.
Mineral soils, which formed the basis of the John Innes Composts,
are now either too expensive or too difficult to obtain in suitable
quality and sufficient quantity. Consequently the grower has been
forced to seek other materials such as peat, perlite, vermiculite,
plastic foam, shredded bark, etc. New types of fertilisers, new
methods of heat sterilisation and new chemical sterilising agents
are also being used.
