Review on 🌱 Unlocking Optimum Growth: The Power of Equivalent Flowers Hydroponic Greenhouse Spectrums by Beth Williams

I bought these bulbs to give some sun to the plants I overwinter in my mud room. They get some natural sunlight, but not all day. I haven't had them for a few days so can't comment on durability but they are very bright and you can see the difference in the light they give off. The photo here was taken at night, so the light you see is from incandescent bulbs.
