Reasons why fake grass works well in a vivarium:
Many reptiles like its strong green colour
Vivarium grass is easy to clean – unlike traditional carpeting (a popular alternative); a clean vivarium is important for the health of the reptile
Fake grass does not need replacing often – unlike newspaper (another popular alternative)
When you do need to replace the lining, it should not be often and will not expensive as there is only a small area involved
A quality fake grass product with a dense weave will be suitable for lining not just the vivariums floor but also the walls and back of it – areas where some reptiles like to climb and which will need to withstand their weight when climbing.

240V Heat Rocks assist reptiles in maintaining body temperature. In the natural environment, rocks hold heat absorbed from the sun and this heat is used by many reptiles, both diurnal and nocturnal, to maintain body temperature and control metabolism and digestion.
These heat rocks are thermostatically controlled to maintain an optimum temperature day and night.
