Root!t Heat Mat and Insulation Kit
These kits come in three sizes, from a compact 14in x 10in ideal for use indoors, up to the large 3ft 11in x 16in which is the perfect size to accommodate five full size trays.
Hobby Heat Mat - designed to provide a uniform, gentle heat across the whole surface to help speed up germination and growth. They have a single mesh element encased within a waterproof, fray-proof casing. They come in three sizes:
Small - 10in / 25cm wide x 14in / 35cm long, 11 watts
Medium - 15ľin / 40cm wide x 23˝in long / 60cm, 30 watts
Large - 15ľin / 40cm wide x 47in long / 120cm, 60 watts.
These mats can be used without a thermostat and will raise temperatures by 10-15*C above the ambient temperature (you will need to turn off the mat if the ambient temperature is high). For automatic, accurate temperature control use together with a thermostat.
Ideally stand watertight trays or pots on the heat mat to prevent water from pooling onto the surface of the mat.
Insulation Mat - designed to be placed underneath the Hobby Heat Mat. It will ensure that all the heat produced by the Heat Mat is directed upward into your trays and pots and not lost into work tops. It is ideal when using a Heat Mat in a greenhouse on metal benching where heat could be easily dissipated. These are supplied to match the size of the heat mat.
The heat mat should not be placed within seed trays, buried in soil or submerged in water. The surface of the heat may exceed 50*C so avoid prolonged skin contact when on.
