Just wanted to share my recent experience with the method of putting your villosa in the fridge. I suggest to not risk doing it. I tried putting it in the fridge as people suggest because my nighttime drops were only getting down to the high 70s and with day time temps of high 80s-90. The villosa was doing fine just not growing. Member recommended to put it in the fridge to give it a nice temperature drop, since it wasn't getting cold enough. I threw it in the fridge and this is what happened.
Now my temps in the fridge are no lower than 48 and there are tons of variables here, since obviously it has worked for some people, but not me. My suggestion is just dont risk it, I know other people do this method fine, but Im making this post so this wont happen to anyone else on such a rare plant. In my experience its better to let the plant be than try and baby because even though the conditions it was growing in were less than ideal, it was still alive. I did nothing to that plant and let it just sit in its sealed cup and it did much better. Every plant that I try to baby never does well and the ones I dont, they acclimate and do just fine. Just some of my thoughts I would share with everyone. You may disagree, this is just my opinion.
PS: I grew this plant for 7 months with no problems
