Temperature Control FAQ

Temperature control in an indoor garden is absolutely vital to your success. HID lights put out a lot of heat, making temperature a problem in most gardens. By following a few simple guidelines, keeping the temperature (and humidity) right in your garden should not be very difficult....especially during late fall and winter. Unfortunately, many indoor gardeners overlook the role temperature plays and end up with all kinds of problems.

For a better understanding of the role temperature plays, check out the Effects of Temperature page. If you have a problem with mold, you might want to look over the Effects of Humidity page. The number one way most gardeners control excess heat and humidity is with a proper exhaust fan setup.

Once you understand just how important it is to control the temperature (and humidity) in your garden, check out the Exhaust Fan Setup page. On that page you will find help for selecting the right fan, tips on setting up the exhaust, and information on using your exhaust fan in conjunction with CO2 or air conditioning. Many answers can be found at the bottom of this page. If you still have question or problem after checking out a few pages, please ask me using the form below....

Problem with Temperature or Humidity?

Along with proper feeding and lighting, good temperature control is vital to the success of your garden. Make sure your exhaust fan is big enough and set up right for your garden. Once your garden is started, unanswered questions can become horrible, nagging problems that prevent you from getting the results you want, believe me! Drop me a line and tell me your story....my experience can help you avoid or fix many problems.
