They appear to be sturdy small plants, however there are noticeable differences between each one. A handful developed into individuals that were obviously bigger and more robust than the others, albeit some appear to be a little runty. Nevertheless, really potent weed with attractive autoflowers. Not a big fan of autos after my first year with them, but I could grow a few next season to build up my stash earlier than October.

I love the skunky and fruity smell and taste of this strain. I planted by seeds both outside and inside and both setup are just great and this strain offers a huge amount of yields! Medically speaking, this strain is just great it also helps me with my insomnia it gives a a good night sleep. The effects is very uplifting and not to mention its appearance which is very appealing because of its narrow leaves and hairy buds. This strain is very recommendable.
