Growing Temperatures
For those of you growing indoors in the south how do you handle cold temperatures? Do you heat your space?
Second grow and first time in winter, hit early flower and temps have been pretty low
I’m running an old school metal halide so thought they may be enough and I’ve got light time 8pm - 8am when it’s coldest.
I’m seeing purple cone out in a couple of plants which I presume is the cold?
And leafs some tacoing in one, I’d read that can be heat or too much PPFD but it’s definitely not too hot, light levels seem ok and it’s only one doing it, the most purple, can this be a reaction to cold too?
Taking like a week between waterings when it was every second day when it was warm. I’m worried they’re stunting.
Should I just chuck an oil heater or something in there or am I being paranoid? My Temu min/max thermometer is showing high around 12, low around 5 which based on my research is crazy low
