Cold temp question.

So...I'm working out of a friends home, and the temps are getting pretty low at nights. The memory on the t-stat says it has been getting down to 50F when lights are off. I'm not around to watch the temp much, this was only an experiment grow. I now added a heat source, and we're in week 6 of bloom. Temps are good now.


Questions are :
How much will this effect the crop?

if there was any problems you would see it right away. Plants die when cold and there isnt any mistaking that, it isnt something going to take days to happen, you wake up and they are dead.

if it was getting this cold for 6 weeks of flowering... dang you may have t flower them an extra week or two.

...they actually look really healthy, but not quite full as normal to be in week 6. I have no problem with letting them bloom longer, and fiqured that was going to be the outcome. But, I'm still wondering, can I expect a normal yield? Common sense tells me no, but...I've never fought the cold, so....just wanting some experienced opinions.

Yeh to get full yield you would need like 6 more weeks of flowering but they will be done in three or 4 weeks under good conditions. Therefore the yield should theoretically be less. That being said you never know they may blow up like crazy when they get good conditions. Don't forget the molasses!

Cold nights will stunt them...

I live in AK... I run heaters in my op 10 months of the year...

50s is too low... it WILL hurt your yield...

it will not kill the plants... nor will it make them do anything weird...

They will just not develop to their full potential...

REMEDY THIS ASAP...

Good Luck...

this is one of the plants in flowering
............

I use a propane heater with a thermostat... like this one... (do a search for vent free heaters)





As for the no sex in 3 weeks of flowering... how old were the plants when you switched...???

It could be the cold or it could be simply that they are too young...

She looks young to me...

yeh roundabout 7 weeks old now

i planted seeds just before new year
