I've been using a Spider Farmer LED 600 grow light this winter. I have noticed that my oncidiums and dendrobiums are forming new growths with acordian-like leaves. The leaves are deeply folded, stiff and hard to separate. Plus there are too many leaves. The plants are not right under the light but are closer that some others. My dendrobium looks like a stalk of corn! I'm keeping phals, papheopedilums and cattleyas are further away from the light and they seem okay. Has anyone else had this problem?
