Just old fans, it looks like.
Your plants look great! With these guys help I was able to pull those plants through. They produced ok. 2oz. But it’s not very potent. I’m on my second round and these are looking great. Just did some LST and trimming on them the other day. So pretty. What do you think about those fabric pots? I tried them, but they are a lot of work to clean after. Do you clean them?
Happy growing! Looks like you are doing well!
