When making up batches of nutrient solutions for your plants, use the Hailea Water Heaters to gently warm the solution to the correct temperature.

When nutrient solution get too cold, plants can go into shock and temporarily stop growing. When roots stay cold for prolonged periods of time, essential nutrition will be locked out. If the reservoir is too warm, there may be issues with root rot that develop, Keep temperatures between 18°C and 20°C to best facillitate growth

You can choose the temperature you prefer by setting the dial on the top – 18 to 20 degrees is normally perfect for hydroponic applications. If the temperature drops below what is set on the adjustable dial, the thermostat will kick in to warm the solution to the desired temperature. The thermostat will then cut out when the water reaches the required temperature and re-engages should the temperature fall. This makes sure the water stays at a uniform temperature throughout the process.

Water Heaters are particularly useful during the winter. When ambient temperatures drop, the reservoir temperature can also start to decrease, which could send the plants into shock resulting in slower development with purpling of stems and leaf veins. If a reservoir is too cold for an extended period of time, calcium and magnesium can be locked out. This will show itself in the plant with deficiencies, even if there is enough magnesium and calcium in the nutrient solution.

Water Chillers will be required during the summer months, when ambient temperatures are high which can cause the reservoir to be too hot, increasing the chances of infection of the roots from diseases such as Pythium.
