  1. How many lumens is enough or recommended amount?

    Try searching for "PAR values". PAR + photosynthetically active radiation usually (but not always) measured in µmols or micro moles. This is in regards to the part of the spectrum that is responsible for plant growth (photosynthesis).
    I have read that our plants need anywhere from 500 µmol and can handle upwards of ~1800-2000 µmol (the sun is in this range). 
    Hope this helps,
