#temps

I have 6 mars hydro ts1000s. Spaced about 10-12 inches apart. As of now I have 8 plants and the fixtures are about 12-15 inches away from the canopy. I am 4 and a half weeks into flower and I was wondering a few things... Should I move them closer? What should my ambient and leaf surface temps...

Wutsup growers, I set up a new grow with a 5x5 Gorilla grow tent and a 1000w Luxx DE Fixture with MH and HPS bulbs. 2 6’ clip fans and a 6’ exhaust fan. At 1000w i am hitting temps up to 104 degrees with the fixture roughly 4 ft from the ground. More fans? anything else i can do to control these...
