Greenhouse Climate Control Systems
Vendor-neutral hub for commercial greenhouse climate control: cooling, heating, humidity management, CO₂ dosing, thermal screens, sensors and full climate automation — specified inside a single RFQ and opened to qualified global manufacturers.
SeedMatchGroup specifies climate equipment inside the buyer's RFQ; we do not sell fans, boilers, computers or controllers directly. All commercial terms are handled privately.
What is a greenhouse climate control system?
It is the combined set of equipment that holds temperature, humidity, CO₂ and light inside the target band: ventilation (roof, side or forced), cooling (pad-and-fan or high-pressure fogging), heating (boiler, heat pump or hot air), thermal and shade screens, dehumidification, CO₂ dosing, sensors and the climate computer that drives them as one strategy. Specified together — not bought line by line — because each element changes the sizing of the others.
Cooling systems
Sized to design outside temperature, target inside temperature and crop humidity band — not to floor area.
Cellulose pads with exhaust fans for hot, dry climates and long-span greenhouses. Low CAPEX, high m³/h.
60–120 bar fogging lines for humidity control, adiabatic cooling and tight VPD management in premium crops.
Wet-wall and fan systems for medium-tech greenhouses across MENA and Sub-Saharan Africa.
Heating systems
Sized to worst-case heat loss including screen strategy, envelope U-value and wind exposure.
Grow-pipe and rail heating with condensing gas, biomass or oil boilers — the standard for high-tech greenhouses.
Low-temperature heating loops with COP 3–4 — green-finance eligible for most commercial projects.
Energy screens cut heat loss 30–50%; shade screens control summer load. Specified with the heating loop, not afterwards.
Humidity, CO₂ & climate computers
Chilled-coil, sorption or heat-pump dehumidifiers for winter humidity in high-tech tomato, pepper and cannabis.
Pure CO₂ tanks or boiler-flue recovery, distributed on the grow-pipe or fogging network.
Multi-zone climate controllers integrating cooling, heating, screens, CO₂, fertigation and alarms.
How do I choose a greenhouse climate control system?
Choose by crop, design outside climate, greenhouse type, energy source, control level and project scale. Size the loads first with these calculators, then put the result in the RFQ.
Airflow and cooling load from area, solar load and target inside temperature.
Pad area and exhaust fan count for evaporative cooling.
Peak heat loss from envelope, design temperature and screens.
Combined climate planning for a specific site.
Integrations
Cooling technology comparison
Selection is driven by outside wet-bulb temperature, greenhouse span and crop humidity tolerance. Typical commercial ranges — confirm against your site's design conditions inside the RFQ.
| System | Best fit | Cooling effect | Indicative CAPEX (USD/m²) | Water & energy | Main limitation |
|---|---|---|---|---|---|
| Pad-and-fan | Hot, dry climates; poly and gutter-connected houses up to 45 m span | 6–12 °C below ambient at low wet-bulb | 12–25 | 3–6 L/m²/day water; 8–14 W/m² fan load | Temperature gradient pad→fan; poor in humid climates |
| High-pressure fogging (60–120 bar) | Wide-span glass, humid climates, VPD-sensitive crops | 3–7 °C plus active humidity control | 18–35 | 1–3 L/m²/day; 4–8 W/m² pump load | Requires RO/filtered water and nozzle maintenance |
| Natural ventilation + screens | Temperate climates, organic and low-OPEX projects | 1–4 °C, radiation load reduction 30–60% | 10–30 (vents + screens) | No water; negligible energy | Insufficient alone above ~35 °C ambient |
| Mechanical chilling / HVACD | Cannabis, propagation, pharma-grade and sealed rooms | Full setpoint control year-round | 60–150 | 40–120 W/m² electrical | Highest CAPEX and OPEX; needs power redundancy |
Ranges are planning-level budget figures for comparison only; final pricing comes from supplier quotes against your specification.
Heating system comparison
Installed heating capacity is set by worst-case heat loss, not floor area. Screens change the answer more than the heat source does.
| Heat source | Typical installed capacity | Relative OPEX | Tenor / lifetime | Financing notes |
|---|---|---|---|---|
| Condensing gas boiler + grow pipe | 200–350 W/m² | Medium — gas price exposed | 20–25 years | Standard senior-debt asset; flue CO₂ recovery adds value |
| Biomass boiler | 250–400 W/m² | Low–medium where fuel is local | 15–20 years | Often grant or climate-window eligible |
| Air-source heat pump | 150–250 W/m² (low-temp loop) | Low with COP 3–4 | 12–18 years | Green-finance eligible; needs firm electrical capacity |
| Ground-source / waste heat | 150–250 W/m² | Lowest | 20–30 years (field) | Longest tenor; highest upfront drilling CAPEX |
| Diesel / LPG hot air | 250–400 W/m² | High | 8–12 years | Cheapest CAPEX; increasingly restricted, weakest lender view |
Control level: what each tier actually gives you
| Tier | Zones & I/O | Controls | Indicative system cost | Typical project |
|---|---|---|---|---|
| Basic controller | 1 zone, 4–8 outputs | Vent, fan, thermostat setpoints | USD 1.5K–6K | Single tunnel, nursery |
| Multi-zone controller | 2–6 zones, 30–80 I/O | Cooling, heating, screens, alarms, data logging | USD 12K–45K | Medium-tech poly 0.5–3 ha |
| Full climate computer | 6+ zones, 150+ I/O | Integrated climate, CO₂, fertigation, energy, VPD strategy, remote access | USD 60K–200K+ | High-tech glass 2 ha and above |

- Soil/water analysis where available
- Any existing concept drawing, BOQ or previous supplier offer
Opens the RFQ Builder pre-scoped as a greenhouse project so suppliers quote structure, covering, climate and irrigation on the same basis. You stay in control — nothing is submitted until you review and confirm.

What to do next
Most organizations move through these four steps in order. Each one can be started independently, and nothing is shared with suppliers until you approve the scope.
Turn your project scope into one supplier-neutral request qualified manufacturers can price consistently.
Site, water, energy, permits and documentation — the readiness work lenders and EPC contractors expect before quoting.
Debt, leasing, blended and export-credit structures for commercial agriculture CAPEX, assessed alongside the technical scope.
Supplier-neutral guidance on greenhouses, CEA, irrigation, nurseries, packing houses and project finance.
How this guidance is produced
We do not manufacture equipment and do not represent a fixed vendor list. Guidance reflects the project, not a catalogue.
Content is prepared and reviewed by sourcing specialists working on live commercial agriculture projects, supported by proprietary technology.
Practice drawn from greenhouse, CEA, irrigation, nursery, packing-house and processing projects across multiple climates and regulatory environments.
Project details stay private. Nothing is published, listed or shared with suppliers without your approval.
