I have run 2 Vivosun 150 watt units mounted at the top of the tent and just moved the plants. It was in a 31x31x63 tent. It will run photos at 65klux with a fairly good pattern until about 14 inches away and then they become 2 separate light patterns. It will do 2 photos and 4 autos.
You have 9 square feet divide 300 watts by 9 and get your average watts per foot. Photos need 42-50 and autos 35-45
