I just changed my light bulbs in my Grand Cayman Orchidarium. I bought replacement bulbs (55W Single Twin Tube 4000 lumens per bulb) and purchased half (3) 3000K bulbs and half (3) 6500K bulbs. I ordered the combination of warm and cool colored bulbs because that is what I have been reading is best, and also came with my T5 light fixture. So as I was changing out the bulbs I noticed that half of the bulbs were 4100K and 3000K bulbs. What the heck? I swear I had looked at them before but I must have looked at the 3000K bulbs when I was writing down the type and model number I needed. I still got great growth and a few nice blooms from some oncidium's, dendrobium's, and a few catt's and the leaves have been a nice light green color. So now I am wondering....does the whole Kelvin thing really matter that much or have my 'chids been missing out?
