Pure CBD Autoflower 2x2 TS600

My first grow and I thought things were going good until I harvested the plant. The buds are not very dense and I think that has to do with my environment, light period temps were around 21c and dark usually around 17c, which from what I have read is just too cold. My next grow I will try to keep a consistent 23c all the time and see if that makes a difference. Overall though it was a cute little plant that looked terrific, smells good and from the little bit I tried smokes nice too.
