    Default Light from 50% tarp

    Have a small greenhouse that gets a high amount light around 11am or 12Pm to about 3pm to 4pm. Have a 50% tarp on parts of the side and on top. Even though there is a lot of light coming through, because there is a tarp is the light coming through still considered direct light? I am wondering if the light would be too high for say a Catt. or Den.

    In my opinion, as long as the leaves don't burn, orchids should be fine. Most of the catts. and send love light. you can measure the intensity of the light it using a light meter and decide.

    Indirect light. As long as there is air movement inside the greenhouse your catts will be fine. In fact, I don't have ANY shadecloth on my greenhouse and it is get some direct light through the panes for about as long as yours does. I hang the vandas in the brightest spots. However, I do have four elm trees at each corner of the greenhouse. Mother nature provides my dappled shade during the summer.

    So when you say your Catt.s are getting direct light you mean it is dappled direct light?

    For most of the day...yes...but not for all of the day. There is direct light hitting them for a couple hours a day but it is somehow "soft". My greenhouse has polycarbonate panels that somehow diffuse the light and create brighter shadows. I know that doesn't make sense but if you could see it you would understand. The rest of the day is dappled light.

    My greenhouse is just a
    pop up kind. S I'm not sure how that affects the degree of light. With that would it matter if a Catt or Den would grow under these conditions?

    In my experience, I throw as much light at a plant as it can take without burning or yellowing. (Gradually up the light levels and they can take A LOT). It really does require a bit of experimentation and time to see what works and what doesn't. Maybe a picture?
