    Wattage advice for QB96v2 + strips

    I am trying to make sure I am at least in the right general range for my grow and I don't have a proper light meter and cannot afford even a cheap one yet. I just want to make sure I am not under-powering things and wasting potential. My setup is a QB96V2 overhead(with homemade reflector), and...

    JDM's Indoor '21 // edit: moved to Grow Journals

    The plan is simple enough. Pop a few seeds and see what happens. Hopefully get some healthy mothers going and cut clones for some sort of SOG or perpetual grow. If things go well, get a few clones nice and bushy and send them outside come spring 2022. I'd also like to collect some pollen and...

    What yields more? Penetration vs Coverage

    If I have the ceiling height than is it better for yields to get a powerful HPS or COB led, or Blackdog type LED and penetrate deep into the canopy and grow taller plants or still go wide with the QB or bar style lights and grow wider but shallower plants??? (aka scrog, lollipopping, etc.) Thanks!
