Temperature Management

Why Temperature Control Matters

Temperature directly affects plant growth, nutrient uptake, and overall plant health. Large temperature swings can slow development and place plants under stress.

Stable temperatures allow plants to grow consistently and make better use of light, nutrients, and CO₂. Good temperature control also helps reduce the risk of mould and environmental problems.

Most plants perform best within set temperature ranges throughout the growth cycle.

Typical temperature ranges include:

Vegetative stage:

• Lights on: 24–30°C

• Lights off: 18–23°C

Flowering stage:

• Lights on: 24–28°C

• Lights off: 20 –22°C

Slightly cooler temperatures during flowering can help improve plant structure and support consistent development. Maintaining steady temperatures between day and night cycles helps prevent stress and uneven growth.

Heating Solutions

Heating equipment helps maintain stable temperatures during colder periods and prevents excessive drops during the dark cycle.

Fan Heaters

Fan heaters provide fast and effective heating. They circulate warm air and quickly raise temperatures when needed.

We stock 2kW and 3kW fan heaters suitable for medium and larger grow spaces.

Fan heaters work well for:

• Rapid temperature increases

• Cold grow rooms

• Winter growing

• Larger spaces

Oil-Filled Radiators

Oil radiators provide steady and consistent heat. They warm the space gradually and help maintain stable temperatures.

Oil radiators are ideal for background heating where gentle and consistent warmth is required.

Tube Heaters

Tube heaters provide low-level background heat and help prevent cold spots. They work well in small grow spaces and propagation areas.

Tube heaters help maintain stable night-time temperatures and reduce temperature swings.

Cooling Solutions

Cooling equipment helps prevent excessive heat during warmer periods or under high lighting levels.

Air Conditioning Units

Air conditioning provides controlled cooling when ventilation alone cannot maintain the correct temperature.

Air conditioning units help maintain stable conditions during warm weather or in sealed grow rooms with high heat output.

Reliable cooling helps prevent heat stress and allows plants to perform consistently under strong lighting.

Maintaining Stable Conditions

The best results come from keeping temperatures stable across the entire grow cycle. Combining heating and cooling equipment allows growers to maintain consistent conditions throughout the year.

Stable temperature control supports healthier plants and more reliable results.
