Hey there I just started my first grow and just built the cabinet and I have a few questions. My grow space is 24 x 16 x 29 in inches. For lighting I am using a home depot vanity fixture that has four sockets. I have a little comp fan but it cannot handle the heat, which is 26 - 28 Celsius when lights are on, with four bulbs in and I was wondering what would be a good 4 inch fan to cool this area? I also have three 2 inch air intake holes and have a scruber at the end of the fan.
