| In the g/h the twinwall blocks 15% of the light plus another 50% is blocked by shade cloth over the g/h. This is more than enough light to grow and bloom high light plants. At times the fc's in this area run 7000.
In my phal area, I have additional 80% shade cloth in the back of the benches up and over the top of the bench area. This is on the west wall. The light in this area runs from 1500 fc's in the morning to 800 fc's from 1 p.m on. When we put up the additional shade cloth in this area I felt like I was growing the phals in the dark. Finally, I am getting the proper leaf size on phals instead of the short chubby leaves from being over lit.
Light meters are not expensive and one of the best pieces of equipment an orchid grower can have in his arsenal. The correct amount of light is more important than the brand of fertilizer you use.
