4 / ‘ RUSSIAN DOLL ’ GREENHOUSES
Use smaller or mini Greenhouses , such as Hartley Botanic ’ s Patio Glasshouse within your main structure to act as a double layer of insulation or to provide a microclimate for plants which need extra warmth . Then , instead of having to heat your whole Greenhouse , you can restrict it to mini Greenhouse pockets .
5 / INSULATION
You can reduce heat-loss by installing winter insulation over glazed areas . The most effective method is to use bubble wrap polythene , cut to size and fixed on the inside of the Greenhouse , close to the glass . This is a fiddly task , since the material has to be cut to fit , and it may take more than one person to install the insulation . Furthermore , the insulation is best occasionally removed during the warmer months to admit more light and to facilitate cleaning .
Partial insulation is also possible . If you wish to protect plants in part of the house , but don ’ t want the arduous task of cladding the whole interior with bubble-wrap , section off part of the structure . You can separate it from the remainder with a polythene sheet , or a bubblewrap curtain , and put vulnerable treasures inside the enclosure .

6 / GREENHOUSE HEATER TYPES
Size : Determining the size of your heater depends on two things : how big your Greenhouse is and how much heat you need to generate . Of course , a more compact Greenhouse can make do with a smaller heater . A larger Greenhouse , on the other hand , will need a more powerful heater . Type : Electric heaters are the safest and most common method of artificial heating for your
Greenhouse . You ’ ll be able to control the temperature and fans help to equally distribute the warmth . Some electric fan heaters can also be used in the summer , switching the cold setting to circulate cooler air .
Other Greenhouse heaters include propane , natural gas , and paraffin heaters . However , these are best suited to smaller Greenhouses . All need to be regularly monitored and refilled .
