Hey all. I wanted to get some opinions on the best kelvin for Chaetomorpha health and growth. Im looking for a LED Par 30 style bulb and have been hearing that 6500k is optimal temperature. The only 6500k Par 30's ive found are specialty grow bulbs and cost a pretty penny and you have to order them from a specialty lighting store. Is anyone running a 5000k daylight LED bulb on their Chaeto? 5000k is the only kelvin store's like Home Cheapo and Blowes sell's in a daylight spectrum. But I don't know how well Chaeto will do under 5000k. ( I've heard not well) Should I just bite the bullet and order a specialty 6500k?
