Want to reduce your greenhouse heat?
Simply mix Hy-Tech Insulating Ceramics into a mixture of whiting and cement which makes a removable whitewash that will reduce the interior temperature dramatically without reducing the light! In the winter the mixture is easily removed allowing more heat to enter.
The whiting alone makes a terrific all natural whitewash for spraying on fruits and vegtables and acts as a sun block and insect repellant.
