Which greenhouse should I choose?
Start with the space you have and what you want to grow. Arched tunnels (Simple Plus, Comfort, Titan) give the most growing area for the money; Gardener 300 adds straight walls for shelving; Victoria Line is the traditional gable shape. Use the comparison page or ask us for a recommendation.
How do I pay?
Checkout is handled by Stripe, which accepts major cards and wallet payments. We never see or store your card details.
Do I need a foundation?
Every greenhouse should sit on a level, anchored base — typically a timber or concrete perimeter. Each product page lists the base requirements for that model.
Can I assemble it myself?
Yes. Frames are bolted together with hand tools and come with instructions. Most people find two adults make assembly much easier.
