Checked out the 1100 fixture, one thing strikes me, is the 2550 btu’s produced from the fixture. That in a 3x3 tent will need lots of air exchanges.
The
British thermal unit (
Btu or
BTU) is a traditional unit of
heat; it is defined as the amount of heat required to raise the temperature of one
pound of water by one degree
Fahrenheit.
Using that metric that a lot of heat. Maybe a better fact would be to obtain the efficiency of that fixture, but unfortunately don’t see that.
As
@JWM2 mentioned, quantum boards would produce the least waste heat, those or a cob set up would be the way I’d go. imho
