Compacted gravel is popular because it drains well and is easier to modify than concrete, but it needs good preparation.
Start with the constraint
A stable compacted base can reduce mud and allow water to drain through the floor while preserving flexibility for future plumbing or bed changes.
What changes the decision
Loose stone, poor edging, or inadequate compaction can make carts and benches unstable. Weed fabric can help but does not replace site drainage.
What to verify before buying
Excavate organic topsoil as needed, establish grade, compact the base in layers, and coordinate structural anchors independently from the loose finish gravel.
How we research greenhouse kits
We compare frame geometry and materials, covering, included components, ventilation, climate fit, working dimensions, anchoring, shipping method, assembly burden, upgrade paths, and completed build cost.
Prices, specifications, firmware, and configuration-driven features can change. Check the current manufacturer page and local requirements before buying or installing equipment.
