I apologize if I have this posted in the wrong section. I'm currently trying take care of/grow a one year old Welwitschia mirabilis that was gifted to me. I have it place under a grow light along with my other plants; it gets about 12 hours of light/day. I noticed that the leaf edges are (which had died off before receiving the plant) are continuing to die off. In other words, It's hard to tell if the leaves are getting longer or if the leaves are progressively dying off (picture see image below). I'm wondering if the AC is drying out the leaves. I normally water it about once a week.
Has anyone had experience growing this plant indoors? I live in Florida and I'm sure the climate here is great for this plant, however my patio gets almost no direct sunlight and I don't want to risk placing it outside if it isn't going to get enough sun.
Based on the image and the information above, am I doing anything wrong? I'd appreciate any advice!
