Greenhouse interior setup.
When setting up a greenhouse interior, aim for three things: functionality, efficiency and comfort. The short answer: grow directly in soil if your greenhouse stands on bare ground, use raised beds if you want easier access, choose large containers on concrete or gravel floors, and add benches, storage, compost or hydroponics as your needs grow. Below are the seven most useful interior elements — you can combine several in one greenhouse.
Which greenhouse layout fits your floor and needs?
| Setup | Floor type | Best for |
|---|---|---|
| Direct in soil | Bare ground | Simplest, most common setup |
| Raised beds | Bare ground | Easier access, no kneeling |
| Large containers | Concrete / gravel | Heated greenhouses, short seasons |
| Hydro / aquaponics | Any | Max productivity, soil-free growing |
1. Planting directly in soil
Traditional planting in a greenhouse.
In standard and tunnel greenhouses without concrete floors, plants can be sown straight into the ground — the simplest and most common setup. Drip lines laid along the rows pair naturally with it.
2. Raised beds
Raised beds in a greenhouse.
The same idea as planting in soil, but built up so plants are easier to reach — no kneeling or bending. Raised beds also warm up faster in spring, though they dry out quicker and benefit most from moisture-controlled watering.
3. Large containers
Containers suit gravel and concrete floors.
When the greenhouse stands on gravel or concrete, deep containers can grow most plants — including root vegetables. A practical choice for heated greenhouses in regions with short growing seasons.
4. Benches, tables and shelves
Benches create work areas and extra plant space.
Benches and shelving create work and relaxation areas, add space for seedlings and small pots in compact greenhouses, and can be arranged to optimise the growing area.
5. Storage
Growing tables with storage underneath.
Soil mixes, seeds, pots and tools all need a home. Organised storage keeps maintenance easy and the space tidy — clutter is an open invitation for pests.
6. Compost
Compost inside a greenhouse.
An internal compost system needs little maintenance and produces excellent fertiliser for soil mixes — and a bin inside the greenhouse releases heat, helping hold higher temperatures at night and on cool days. Outdoor compost next to the greenhouse adds similar benefits plus insulation.
7. Aquaponic and hydroponic systems
Hydroponic irrigation system.
First-time installation can be expensive and complex, but these systems are highly productive. Aquaponics converts fish waste into plant fertiliser via nutrient-rich water; hydroponics mixes fertilisers and minerals directly into the water, no fish tank needed.
Frequently Asked Questions
What is the simplest greenhouse interior setup?
Planting directly in the soil — no construction needed, and it works in any greenhouse that stands on bare ground.
Do raised beds need different watering than ground beds?
Yes — raised beds drain and dry faster, so they usually need more frequent, smaller waterings. A soil-moisture-based system adjusts this automatically per zone.
Can one watering system cover beds, containers and shelves?
Yes, if it supports independent zones — the GRAAS iRigator waters up to 4 zones separately, so containers and beds each get their own schedule.
