    Default Is my light good enough? HLG 100 RSPEC

    I'm using a secret garden, Dark Street 60, 60cm x 60cm x 158cm grow tent. HLG 100 RSPEC grow light.This fixture produces 220 PPF, 14,000+ Lumens with just 95 Watts of power. Equivalent to 220W T5 or 300W CFL output or 200W metal halide.

    I have 4 autoflowering plants in there.

    Thanks

    I think you will struggle with 4 plants under that light bud.

    I usually aim for 100w per plant, if I was you I would move atleast two if not three of them somewhere else.
    Good luck with your grow.

    MrC and Kro did a side by side grow with that light to great success this year. They both grew excellent SINGLE plants.

    Moar power or fewer plants bud.

    Cheers,

    But they are not getting in each others way or interfering with each others light.
    They're occupying their own spaces.

    Are they people that have posted grow diaries on here?
    Were they photo period plants?

    Thanks

    I'm pretty sure @LEDHarry says 35watts per square foot.

    Here's the fastest chart I could find that was similar:

    That aside, 4 plants in a 2x2 is a LOT of plants. You'd probably yield the same with 2 plants under 50 watts each.

    To each their own. I'd love to see you successful! Please share your progress if you bring 4 to flower.

    Cheers,
    B

    Be careful, that section tends to eat up a whole bunch of time.

    I grow in a 2x2 with an HLG 100. Best grows are a single photoperiod. Autos are not always reliable on size.

    I have also jammed 3 photos in a 2x2 but its a pain in the ass.
