| How much light is enough
I am working on nursing a Phal back to life that a friend had bought in Hawaii. Being as I don't have a south facing window and it is fairly cold here in Ohio I built a small artificle greenhouse in my basement. I am able to control all the usual climate settings in it. Given this orchid hasn't had much care and was not kept in a window before I received it the other week, how much light should I give it this time of year to start?? I heard anywhere from 12-16 hours a day. The lighting is artificle 60W grow bulbs placed two feet above the plants. I keep a digital thermometer on the surface of the soil to make sure the leaves don't get too warm(no higher than 82 degrees is what I could best figure out from reading). |
