Yeah...but the T5's i currently use block the tank and all the heat is trapped in there. Plus the ballast is also internal.
With the separate external ballasts and the fact that there is a clearance thanks to the legs, I am assuming that temperature at plant level shouldn't be a lot hotter than now (also since hot air rises). I will have a humidifier in the side blowing cold air in.
On extremely hot days in summer, perhaps I can turn off the MH and use only the T5.
