In the low 20's here in new England, tent is hovering around 70F, a little on the cool side for my liking, might slow things down a bit.

First tie down and leaf tucking, shifted to bloom nutes. This plant is quite a bit smaller than my prior OSMH, which was a beast.

It was an 8 day dry. Being a small compact plant, I performed twice daily branch separation to avoid mold. Medium bud density, gassy fruity smell.
