dankbros Reviewed by dankbros on . Keeping my closet at temperature.... Hey, I've recently started my grow room in my closet. I have a 600W HPS light that is producing a lot of heat. I've got a vent system going through to the outside with several fans for circulation. It's not even that hot out yet in sacramento and I'm having trouble keeping the temp between 70-80 degrees. I'm considering getting a portable AC unit to help with the coolness. Has anyone tried this or have any suggestions or do you think the AC unit is the only way to go. Thanks! :jointsmile: Rating: 5
