## Description

Product Description

Review: Good for even bigger tents. - Great system, does what it says. Keeping a 180x120x60 tent cool and smell free. the app is really handy and once its all set up your temp and humidity can be automated pretty easily. tutorials on youtube are all you need for the controller or app, but would be handy to have a proper instruction manual for this in the box. Even in this size tent it sucks the sides of it in when its on full power, quiet but not the quietest, though its probably as quiet as it can be for its power. On low power its virtually silent. seems really well built and fits the tent nicely.
Review: Nice and quite - Cheap and worth the money
