Setting up a good air conditioning system for your indoor growing is essential and will require the use of ducting. This is so air can be delivered to and removed from the space in which your plants are being cultivated. Of course, the size of your ducting will depend on the type of system you are setting up. This will also affect the size of the Flanged Spigots you use in order to attach your ducting to the place where it will come out in your cultivation room or a grow cupboard. These Flanged Spigots will enable you to fix the ducting firmly, allowing the air conditioning to work efficiently and effectively, and as a result improving the health of your crops.
