    Frequently Asked Questions

    • Can I choose which side the louvre and watering system go?

      Yes, you have flexibility in positioning these features. The watering system connection can be fitted on either end for Classic models, while the louvre vent typically fits on the left but can be adapted for the right side.

    • Does the mist spray affect the wall?

      The mist spray uses less water than natural rainfall would on the wall, so it shouldn't cause any issues. The greenhouse actually provides some protection to the wall from the elements.

    • Can I automate the watering?

      Absolutely! We offer a hose end timer that can automate your watering system, perfect for when you're away or busy.

    • How does the louvre vent work?

      The louvre vent is a clever, sun-powered device that doesn't require electricity. It uses an oil-filled cylinder that expands with heat to open the vent and contracts to close it as temperatures drop.

    • Is the greenhouse easy to build?

      Yes, our greenhouses are designed for easy assembly. We provide clear, comprehensive instruction booklets with step-by-step guides to make the process straightforward.

    • Do I need to fix the greenhouse to a wall?

      While walls are ideal for their heat-absorbing properties, it's not necessary. We offer glass-backed models for freestanding options if you don't have a suitable wall available.
