55 lights off

hi and welcome,
I have 15 plants in to the 5-6 week flowering
my problem is the cold!
they are ok when lights on 2x600watt hps (overnight)
but during the day they have been hitting 55f
thuis has only been a problem for the last week,
is this a big problem?

thats pretty cold. you might want to think of getting a small space heater.

I heard less than that can cause shock.

From what Ive heard below 50 causes problems I'm around that myself I just got a cheap heater put it on low and it kicks on and off when needed. Not a huge investment better to be safe then sorry Good Luck with the temps

the heater i got is 1800 watt to much i cant find a low watt heater that swiches off when at right temp

They are all going to draw a ton of juice while they are on, its just the nature of the heater. That is unless you go with some kind of propane heater or something of the sort - but I sure as hell wouldn't recommend that.

If your space is small enough a small one, set low to keep the temps in the low 60's at night wont draw that much overall.

get the type of system that burns shit and puts out co2 at the same time. i forget what its called. heat, co2, and maybe cheaper than electric?
