Hydroponic Gardening – Systems – Air Cooling

While many plants thrive in high temperatures, there is a limit to the amount of heat any particular plant can tolerate before it begins to wilt and die. The very nature of hydroponic gardening, from grow lights to enclosed greenhouses, makes it necessary to provide a system of air-cooling for your fruits, vegetables or flowers. Let’s explore what can raise the temperatures in your growing area and how to effectively initiate air-cooling.

The very structure of a greenhouse allows for heat to build up. The sun coming through glass or plastic can heat an enclosed area quickly. By providing vents throughout the greenhouse, and fans that blow the heat toward the vents, you can help cool the air inside. Warm air rises, so having vents placed near the roof on either end of the greenhouse will
Help alleviate excessive heat.

The use of CO2 can increase both the heat and the humidity within the greenhouse. The best way to help combat this is to set up vent fans. Placing these on a timer will enable the hydroponic gardener to periodically blow out hot, humid air, allowing fresh, cooler air to take its place. Adding a dehumidifier to the growing area will additionally help with the high humidity that often accompanies the use of CO2.

The biggest heat creators, by far, are grow lights. The heat given off by the grow lights can cause damage to plants if it is not decreased considerably. Many lights used in hydroponic gardening come with a fan system meant for air-cooling already incorporated in their design. If you are using a lighting system that does not come with such fans, it is advisable to set up some fans to help keep the air around the plants circulating and cooler. One powerful enough to cause the plants to move slightly is preferable, as this will also help prevent light landing only on one spot of the plant leaves, causing them to burn.

There are many systems available solely for the purpose of air-cooling in your hydroponic growing area. Some of these consist of fans and vents; others include a cooling pad and baffles. Baffles are installed to help keep cooler air at plant level. These are not essential, but are nice to have to help keep your fruits, vegetables and flowers cool and happy.

Once you have taken care that your plants are cool enough to grow well, you will want to do all you can to keep your hydroponic garden healthy. Feeding them Advanced Nutrients products will accomplish this task.

    Too right buddy. If anyone doubts the heat power of lights, just try standing under a 1000w HID. Crispy! (Or ask any stage actor whether the spots make them warmer.)

    Heck, even those sweet high-powered LEDs put off a boatload of heat (for diodes – they’re practically cold compared to a HID.)
