Hydroponics in Cold Weather

Emporium Hydroponics • Dec 07, 2023

Plenty of light and warmth!

Hydroponics in cold weather needs good stabilisaton of heating and timing of lighting

Even though hydroponics is carried out indoors it is easy to get concerned about a lack of light and warmth during the cold, dark winter months!


However, simple technology makes it easy and straightforward to give your plants exactly what they need.


The beauty of hydroponics is that it can be done all year round with the same results, regardless of what the weather is doing outdoors.

Temperature Control

Keep the water in a warm environment. If using tap water that can be particularly cold during winter so pre-store it in bottles in the warm environment. This will reduce the stress on your plants.


A heat retention mat placed under your pots can help to keep a stable temperature.


A thermostat combined with a great heater will help to keep the surrounding temperature between 18 and 21 degrees centrigrade when the lights are out. When the lights are on aim for 25 to 28 degrees.

Use a heater during cold weather to keep your plants warm in their hydroponic grow room

Lighting Control

We are not always planning to use natural sunlight in a hydroponics grow room as many of them are indoors and there are a couple of options for a nice straightforward alternative.


LED lighting is very energy efficient so as well as being an excellent source they will also reduce your power consumption quite significantly. There are plenty of products to choose from and LED lighting has a long life span.


Your plants need about 8 to 10 hours of light each day and rather than doing this manually simply get a decent timer.

Timers will control the lighting or the heating for your plants in  an indoor hydrponics grow room

What to Grow?

We all have our preferences and long term growers are often very accustomed to specific crops.


If you are just starting out or fancy a change then some vegetables that will grow nicely include beansprouts, spinach, carrots and broccoli.


Whatever you choose to grow, enjoy!
