    The Spectrum King Mother's Lil Helper LED grow light is the ideal replacement for traditional veg/clone lighting

    For vegetative and mother plants, the light can cover a 4’ x 4’ area 18″ above the canopy.

    90-degree Reflector

    The Mother's Lil Helper LED Grow Light has 90-degree reflectors specially designed to spread light evenly.

        Customer Reviews

        Based on 2 reviews

        Actually not impressed. The light puts off a lot or heat compared to some other mfg.

        Spectrum King SK402

        Been running this light for a week now and the plants are loving it. Be aware this light runs pretty warm and will run up the temps.
