I have a 4x4x7 grow tent and use a 400MH for Veg and 400HPS for flower;

I am 4 weeks into flower and just put the 400MH back in with the 400HPS; 800w for the last 4-5weeks.

Just 400HPS my temp is 81c(day) 69c(night)

both 400HPS and 400MH my temp is 89c(day) 69c(night)

Where do we draw the line with heat vs wattage. do i keep the extra 400W and take the increase to 89c??
