Every cold state needs a 600hps for there led setup

I got an 8 x 8 with 4 -450 M-hydro led’s in there with a 115 watt all red 660nm ufo that i run 85 gallons of soil in my small ass basement apartment setup… i still need to bust out another 20 gallons with my old skool ushio 600 hps batwing style foundation.. because i cant fuckin breath” no fresh air -gotta open window more, then its to fuckin cold for them to grow.. so the demand for O2 goes up so fire up old faithful in The corner soo i can open the window more and me happy plants happy

all I got is this...

Still going to get cold during lights out.
There's strains like Northern Lights & White Widow that are bred for cooler climes.

Good luck
