    I am not experienced enough to just judge my light levels. I do have a light meter. I would like to know if any of you have a chart that lists what foot-candles(FC) equate to certain lighting conditions. Example: Bright light = 3000 to 4000 FC, Partial = etc, etc. Thanks

    Thanks Harry, I don't know why I didn't think of that first. I didn't see a stand alone chart, but used his search feature and just wrote down each of the ranges. Here is what I came up with.

    Full Sun = 3500-5000FC
    Full Sun to Bright = 3000-4000FC
    Bright to Full Sun = 2750-3750FC
    Bright = 2500-3500FC
    Bright to Shade = 2000-3000FC
    Shade to Bright = 1500-2500FC
    Shade = 500-1500FC

    I am generally pretty vague about how much light stuff gets. Here's how I define light amounts:

    Full sun - self explanatory
    Bright - If I put my fingers between the light source and the plant, my hand casts a shadow
    Bright shade - No hand shadow, but occasional dappled sunlight
    Shade - Not the darkest corners of my greenhouse, but they rarely get full sun
    Full shade - Darkest areas of my GH

    Hope that helps.
