How far will my LEDs reach and still effectively bloom?

    Im rockin 4 vero 29c run from HLG- 320H-C2100B.

    My closet is 10' tall & has some built in wooden shelves about half way up. Because of those shelves (do not wish to rip them out) I only ever thought to use the bottom half of closet for bloom. Then I read Ed Rosenthal's book about 'closet growing' & every diagram in the book uses shelves to maximize growing space. He would usually just hang one HID light at top of the closet. So now Im wondering:

    If I hang my vero rig 9' high, will it still effectively bloom the plants that are on the floor? That would be a 6' distance from canopy if my plants are 3' tall.

    For that distance you would want reflectors. Is it not possible to attach to a system so you can lower/raise light as you need?

    no, thats entirely too far, i wouldn't want to try over half of that distance between your canopy and light

    Definitely not. Not only is it too far away, any shelves would block the light from reaching the bottom even if the lights were strong enough.

    18" to 24" on average is the projection depth of most leds, cobs, etc. If you are more than that distance you are wasting your energy.

    It will not effectively bloom at 6 foot from canopy. Not saying it won't bloom, but no where near potential.
    18" to 24" as (VegasWinner stated) is where you should start from. Raise/lower as needed to cover floor footprint.
    Good luck :)
