Tunnel House Thermic Solar Auto Vent Opener - Aluminium

One thing that’s important in a Tunnel House is ventilation – keeping the environment warm enough to encourage growth but too hot and growth will stop.
Add on the Automatic opening Thermic Ram Roof Vent Opener (solar heat driven no power required) so you can sit back and know that your auto vent opener will do the work for you to open & close your vent as required.
Best when ordered with a Tunnel House Roof Vent so you can get the benefits from both.

Shipping direct from the central North Island warehouse allows you to get growing faster.

Its best to add on this product at the time of ordering your Glasshouse, but if your ordering afterwards please directly for your small item shipping charges on hello@urbanbackyards.nz
