Growing cannabis takes a lot of equipment, especially if you are growing indoors. Whether you grow in soil or in a hydroponics system, in a grow tent, grow cabinet or in a dedicated grow room, you are going to need ventilation to control the temperature. Your ventilation needs depend on the size of your grow op, the climate you live in, and the type of lighting you use and even the stage of life that your plants are in, from seedling to flower. Of course, hotter climates and locations with high humidity levels will need more ventilation. Cannabis plants enjoy a temperature range of about 70 to 90 degrees Fahrenheit, just like humans. Some grow lights produce more heat than others, increasing your need for ventilation. HID and HPS light bulbs use a lot of energy, and a large percentage of the electricity they use is emitted as heat. Things can get pretty steamy in your grow room if you do not use inline fans to dissipate that heat. LED lights and fluorescent lights can reduce the heat in your grow room, but they do not eliminate it completely.

It can be very expensive to set up a grow op from scratch with all of the equipment you need to purchase. You want to make sure that you buy quality equipment that will last, but it is not necessary to break the bank before you even have your first harvest! Inline fans come in sizes ranging from 4″ to 12″ and you also should purchase ducting and a speed controller to get them hooked up. The inline fans in this article are perfect for beginners, and will save you a lot of money up front. When you are ready to upgrade, head over to our Top 10 Best Inline Fans For Cannabis Grow Rooms article to see the top of the line products.
