Despite the cold and frosty days my plants continue to grow

With the recent cold days my plants keep growing slowly but steadily, the smaller plants are a new genetics in my garden and I also think that the land I bought is bad.

The largest plant is growing towards the sides since the short hours of light and the few nutrients in the soil will limit its height. I am happy with this plant because it is already forming buds. I think at this rate I'll have some bragging buds by the end of this month.
