I need some help please. I have a pencil cactus that I ordered on Etsy. It was in rough shape when it arrived. It has definitely grown in height as well as width but it is not red as it should be. I’m assuming it needs more light but I read somewhere that this particular cactus does not like direct light. I had a grow light right on it but then read that they don’t like that much light so I moved the grow light up quite a bit. Should I move it back?? Thank you!
