how low a temp is toooo low??

[zachrockbadenof]

growing in a 4x3.5ft tent with '2' 315 cmh's- during the day the temp ranges between 74/80 (humidity 45/58), but at nite is down to 57/59f... plants are 3weeks into 12/12 looking fine, but the question is what temp is tooo low???

Ideally, youd want them between 60-80 degrees, too cold or too hot and could shock them. So try and keep a little of a constant temp

If I remember right, the stop growing at 55 or 60F.

For me, perfect is a 10 degree difference in day and night with night being 70-75F and day being 80-85F.

I never let my room go below 70.

Cannabis growth in the veg phase slows to a crawl around 50-55F.

Bringing it up to 65°F at night will allow better growth.

many thanks guys... just bumped the thermostat to 67f... i want happy girls...

The only thing worse than a crawl in growing is bugs. Good lord.

woke this morn, n lowest temp during past 24hrs was 66f... almost there- will crack up another 2degrees for the overnite's...

Hey dont worry, you got this. Cannabis can be a very forgiving plant.

For fully sealed, climate controlled indoor rooms:

No colder than 68F during lights out. No hotter than 76F with lights on.
Co2 on at 900 off at 1100.

The sweet spot.
