Even a small greenhouse opens up vast new possibilities -from early vegetables to orchids. Equipment available can give complete, automatic control of cultivation.
A mini-greenhouse can free a gardener from the tyranny of the weather.
Under cover of glass, he can grow plants that would suffer from cold, heavy rain and wind if they were grown in the open. Mini-greenhouses may be either heated or unheated. An unheated mini-greenhouse will not keep out frost, but it creates warmer conditions for plants in the growing season. This extra heat speeds the ripening of crops, and improves the flowering of many decorative plants.
An un-heated mini-greenhouse also protects plants from strong winds and rain and from attacks by birds, animals and some other pests. Perhaps its most valuable function is to lengthen the growing season. Plants can be started into growth early in the spring, and either kept in the mini-greenhouse or planted out in the garden. In the mini-greenhouse, plants will grow on well into the autumn.
This artificial growing season is achieved in spring by the glass trapping the heat of the sun on clear days, and in autumn by retaining warmth which has built up in the soil and brickwork during summer.
