Frequently Asked Questions (FAQs)

1. Should a greenhouse be waterproof?

This is a hazard best avoided. It's a fact that no greenhouse is 100% waterproof! Water can come in under the bottom of the base, from watering spills or from an occasional leak and so it's very important to allow the water somewhere to escape naturally.

2. Are plastic greenhouse any good?

Mini plastic greenhouses are indeed good additions to a garden or allotment. They are especially effective at seed starting and plant cloning. Another advantage of using mini plastic greenhouses is that they are mobile, and also they take up little space.

3. Are polytunnels better than greenhouses?

Polytunnels are so much better value than greenhouses. And the bigger the planting area the more money you'll save by opting for a polytunnel. Of course, there are exceptions to every rule. The exception here is if you only have a small space.
