    LED vs Solar Power (Offgrid)

    Example: What would be the total cost of a solar system to power 12 x 650W LED lights offgrid in a sealed grow room? The intranet states (several places) that a 5kw system generates roughly 20kwh per day. A 650W LED uses 7.8kwh per day @ 12 hours. 12 lights would use a total of 93.6kwh per...

    Twin Peaks

    Hello all, If I run the Mars Hydro FC-E6500 in a 4x4 or 5x5 will their be a difference in yield?
