Although some plant growing lights might require extra space on your countertop or windowsill, Lordem’s is considerably more space-saving because it can be staked into your potted plant’s soil. The halo-shaped light can be tilted to fit the angle at which your plant is growing, and its height can be adjusted as your plant grows taller, too. There are four levels of brightness you can choose from, so the grow light can act as a supplementary light even on sunny days. Shoppers also love that it has a timer and that it’s a great size for desk plants. “I wanted a real live plant but have zero windows in my work area,” wrote the reviewer. “This little light has been fantastic.” Another shopper said they wish they’d found these lights sooner, adding that their brightness is “excellent” and that they produce “more light than a Northern window.” One last reviewer said the lights “saved” their plants, writing, “these lights help my plants thrive”—even in the basement.
