Common questions

Frequently asked questions

Where should I start if I have never owned a greenhouse?

Start with your growing plan, then measure the available plot, access and door clearance. Our first-greenhouse checklist brings together the decisions about size, position, base, ventilation and equipment before you buy.

How do I choose the right greenhouse size?

Plan the internal path and the space needed for staging, pots and mature crops, not just the outside footprint. Leave room around the structure for installation and maintenance. Our size guide compares compact and larger layouts.

Do I need to heat a greenhouse?

Not every growing plan needs heating. Many gardeners use an unheated greenhouse for seasonal crops and protection from rain and wind. Tender plants need a crop-specific temperature plan; a greenhouse does not guarantee frost-free conditions.

Can this site help if I already have a greenhouse?

Yes. The growing, climate and watering, and maintenance hubs cover crop planning, ventilation, irrigation, cleaning and repairs. For a specific issue, use the greenhouse help page to find the most relevant guide.
