my night temps are cold. actual affect?

my night temps are cold, will this significantly affect my bud growth, im in early flowering and buds are appearing pretty fast. day 10 of flower pic. . .

oh yeah, they are probably in the high 50-60 degree range at night, 75 during day

correction* it is at 50-60 degree range at night, 75 during day. one plant

Shit man, 60 would be perfect. U want a good 10-15 degree drop in temps at night. this induces flowering as the plant thinks winters comin, short days, long nights, and cool temps, among other things as well, will trigger the plants natural instincts. U may get some purple on em, but not much else.

thats not too cold..you should be all set

thats awesome. whats too cold then. winters comin my way and by december im afraid it might get into the 40s at night in there. probably only low 50s though

Don't trip, if it's inside it'll be fine. Frost is a bitch outdoors, but i don't think u'll have that prob inside though.

temps do not induce flowering. diminishing light induces flowering....

32f is bad. anything higher is acceptable.

i love this site, its like im connected by brain waves or something to everyone. Everytime i have a problem or a question i come on here and someone just asked that question lol. I just put my plant into flower and this is my first night of dark and it got rather cold in my closet, got down to 60 so i had to open the door to get warm air in there and hang a blanket around the plant to block light

a 10 degree drop from day temp is ideal actually

I just harvested my first grow so im no expert. I live very far north in Norway and i had nighttime temps( ranging from 40 to 60 during the last 6 weeks of flowering. i had one sativa and one indica plant. The sativa plant produced very little but the indica plant produced very good. Maybe indicas tolerate cold temps better? or maybe the sativa was just a bad seed.

Think you will be fine though.

how cold is the coldest it should got at night - in c?

scoped

maybe what he should have said its that it increases oil and thc production, because the plant knows its time to flower because of the decrease in temp. Yes lights tell it when to do what it does, but it does receive other signals that trigger other parts of the process... Hence the purple thing, cause apparently that happens with a 10+ drop in temp from day to night... Never done it myself, so, just going with what I heard...

Around 15 C, I imagine.. anything colder and you are risking damage to the plants.. I would think you would want it to be kept between 20-23 degrees C., or 70-80 F, unless you add CO2, which I also heard (not tried yet) that requires a temp increase to be effective.. still researching it before I give it a shot.. Supposed to be a 2-2.5 x increase in yield amounts...

the purple thing when induced by cold is the same as leaves changing color on the trees. i think it's a phosphorous related reaction.

you could put a small space heater in the grow area and timer it to go on when the lights cut-off. That would help you maintain consistent temps. If you get one with a thermostat, you can adjust it so you get a slight drop in temp, but nothing too drastic. Just make sure the heater doesn't emit any light. You can put electicral tape over lighted power buttons. It's difficult to run heaters and lamps at the same time on the same circuit, because most heaters are 1500 watts and use 12.5 amps. Some heaters have a "high" and a "low" setting, where the low setting uses half as many watts...so if you want to run it while the light is on, on the same circuit, get one that has that feature and run it on "low."

what actually needs the warmth more? the roots and soil, or the foiliage. because i was thinking about maybe putting an electric blanket under and around the pot when it gets really cold. just a thought
