Low Grow Room Temps

[gunja]

Hey guys and gals, Im currently growing some Holands Hope clones Indoors under a 600W HPS (were vegging under MH) They are suppost to be cold resistant. The problem is that its the middle of winter here and it gets down to around 43F with the lights off. Will this effect them overly and should I put a heater in there?

Thanks!

I would put the heater in there...but, your plants should still grow and produce, just with diminished yield.

I would get a heater...

Heater for sure. Anything under 60F will stunt or stop growth completely.
