not sure how much the temp slows them, but by looking at your buds and how the white little hairs look, I would say you still have 3-4 weeks of growth to go.
how long did you veg the plant for then?? should have vegged for april and may, then flowered in June/July, done some time in august if your in control of the lights but if your outside I guess you have to do what the sun says. but you still have a few weeks to go.
All I did is was put them on the balcony, and water them like normal plants(watered them with some nutrients I found in my local shop with 10 times). The temperature is going to get below 0 celsius soonish here, so I have to do something. I have 5 more besides this one, and they all look really good. I was thinking about buying some kind of heating so that I can heat up my balcony before I go to bed.
if your just leaving them outside, I would find somewhere dark to put them inside for the night, that way they stay warm, and move them back out for the day, if you have the room.
Yea, that's what I was doing for a while, but now I jsut leave the door open between the balcony and my room, so the temp is about 20-21 degrees celsius.
If the plant sees more than 12 hours of light in a day, it will continue to veg as opposed to flower.. If the dark period is interrupted during flower, the plant will think the flower season is over and it will possibly hermie to try to make itself reproduce because it thinks it is going to die. also, your plants are female, that is what the little white hairs are about. As the plant ripens those hairs will die and pull back into their calyx, making your plant look like nice buds.
