    Default Artificial Lighting for orchids

    Purchased 200 watt 6500K 8000 lumen lighting system. Would this amount of light be sufficient for Cattleya Orchids and Denfobium Orchids. Also have newly purchased Oncidium ampliatum, and Renanthera imshootian, and Neofinetia. Hopefully they are compatible. Any thoughts?

    You'll be able to grow anything under that light, but you're going to need to vary the lamp-to-plant distance to accommodate the differing light needs of those plants.

    I have Cattleya, Dendrobium, Oncidium, and Neofinetia. I have them all growing in bright, in-direct light. While not under light, they were all in a southern facing room with 12-14 hours of this light. This has been going on for a month. I noticed the other day, that my Neos and my Oncidiums, were getting too washed out, so I moved them to an east facing sun room a week ago. The Oncidiums are recovering their bright green color, the Neos, can't really tell yet--they grow very slowly.

    This is a long answer, based on my observations, the Oncidiums and the Neos might prefer less light than Cattleyas. I do not know about Renantheras.
