cold indoor growing

[raiders420]

What up. Anyone from tahoe area or somewhere else with sub freezing temps. i'm wondering about indoor growing temp problems when it's thirty in the day and ten degrees at night. Using a 400w hps, in a 3'x2'x5' grow tent. Will the heat from the light even out the freezing temps. granted it's warmer in my house but still gets colder at night

p.s. I'll still be providing adequate ventilation

put a temp guage in the tent....try not to get below 60-65 in veg ....add a small space heater if nessary

[Revanche21]

during light on periods, it will probably be sufficient?

[raiders420]

thanks, yea thats what i was thinking. I'm kinda wondering how much i should exhaust when it's real cold out. that maybe pulling to much heat out might make it to cold. But yea i'll just check the temp and trial and error. Just wondering if anyone out there has faced this senario

Flowering its ok to be in the 50s while in the dark...thats the same temp outside for fall weather at night.......we are trying to imitate mother nature's seasons

The plants/buds will have purple to it also....mine does :thumbsup:

im wondering about this also as i currently have some plants going indoor but where it gets no heat except for from the lights. So far my temps have been any where from 28 to 80 but mostly in the 50s-60s. one thing i have noticed with this "cold" grow is i have gotten really thick stems and also lots of purple colors :hippy: but im worried about it getting colder!! i heard they dont really like it below 40 but can survive as long as their not frozen?? any thoughts guys?

for prolly $40 in parts and a little inginuity, you can build a control with a house hold thermostat, a relay and a transformer to turn the ventilation on and off as needed to maintain the desired temp.

Get rid of the ventilation and try keep your temperatures above 60 deg F, otherwise you just will not see much in the way of growth below 60F. I'd get a thermostatic fan controller (about $30 at most grow shops) and connect it into your system (remove the glass from the ventilation hoods, if you haven't already as this will help).

This will be your biggest problem and I'd suggest running your lights during the night to off-set the temperature issues. I'd also get a small electric heater for the space during the off light period, and cut down on the cold air ventilation.

You will have some very nice color by the end.
