Lighting for my new orchidarium - enough or too much?
Hi Everyone
I am getting an orchidarium made out of wood with low iron (Diamant) glass to allow maximum light through. It will be 40 to 43 inch tall by 51 inch long by 28 inch front to back.
I am a little confused about my light output and need some assistance. I already have 2 x 4 (54 Watt) tube DE T5 light units with individual parabolic reflectors over each tube. I can get Sylvania Growlux tubes which I think are rated for 8500k. I dont really want metal halides.
My question is what will I be able to grow with this lighting. Is it too much or not enough for low light orchids at the bottom and high light needs at the top? I will raise pots off the base of the orchidarium with eggcrate shelving.
Many thanks
Brett
