3 reviews for GLT8 20W T8 Indoor Plant Grow Light

  1. Eric J. Merfeld

    These lights have proven to be great so far. I’m using them with herb seedlings, greens, some houseplants, and a small kumquat tree and all are very happy. Temperatures here in the midwest were subzero for most of the last 2 and a half weeks and it was overcast so the fact that these kept the kumquat flowering feels like a good sign. They’re easy to put together and intuitive enough that instructions aren’t necessary. They put out a little heat which is good for baby plants but does dry them out a little quicker than normal but that’s true with any lights I’ve used.

    What a fantastic buy! I rigged up these lights to get my seedlings started. Everything is growing well. The lights are warm to the touch but not hot. I put them on a timer for 16 hours a day and covered the whole thing with space blankets to keep the seedlings a little warmer in my basement! I’ve been using them for about 6 weeks now and my utility bill has not jumped up so I am thrilled! I will probably purchase more next season to expand.

    Used these over 4 standard seedling flats, 3 per shelf. To eliminate leggy growth they needed to be positioned 4-5in over the surface. They are bright, 3 of them are bright enough that my normal lights in my room seemed dim in comparison. Lights come with three plugs with switches and quite a few light to light cords as well as double sided tape, zip ties, screws with molly bolts, and clips so you can attach to pretty much anything. Overall, pleased with my purchase, might buy some shorter ones so I can put them in an aquarium when I start seeds in there.
