Has anyone used these for supplemental plant growth? I was thinking of attaching on the interior of a sunlight to provide light in winter.

Doubtful that it will work see wikipedia http://en.wikipedia.org/wiki/Grow_light. These lights do not have a multiple wide wavelengths. Typically these can be bought as a warm white more like a incandescent light bulb or cool white like an office environment. See color chart http://www.theledlight.com/color_chart.html These Led lights are around 3000K they do not have the lower wavelengths that the sun provides.

Yes, this is what my wife purchased them for. However...and as Ellen G. stated, they need to get adequate sunlight. This was a problem in our house in the location where my wife intended. Another thing to beware of is the watering issue. With a wall design, one might use an array of small containers to hold the plants individually; it's likely that such containers won't have drainage holes. Be very careful with over-watering the plants without drainage to the soil else you will quickly find dead succulents from root rot!

Well, the 4 lights give out twice as much light and enable you to grow plants on a deeper shelf. I really like this light, and last year my seedlings grew better under these lamps than under my 2 light lamps. I didn't find them to put out too much heat, but they do give some warmth, which is good. I made an L-shape growing area with 2 sets of shelves. I put up 2 four-feet lamps on several shelves, and this lamp on the shorter side.

it's really up to the bulb you choose. this fixture does not include bulbs. I recommend you go to Home Depot or Lowes and buy a 4 tube shop fixture and grow light bulbs, put them within 8-10 inches of your plants and they will continue through the entire plant life. My experience is that grow lights are not quite as effective as sunlight for vegetable production, but they can be pretty effective if you run them 12-14 hours per day, and fluorescent uses much less power and makes less heat than comparable output from incandescent. .

If being used as the main source of light I would say no. They would be perfect for extra light above your desk but I wouldn't be happy with 2 of these as the main lighting source.

Yes, I am using these both inside and outside. Obviously needs to be in an approved outdoor fixture. These are better than CFL's outside, especially in cold weather, as they are instantly at full brightness without any warm-up period.

I bought them in the summer and put them up to light my porch, but they are not in direct sunlight though. I've been very happy with them so far though.

I honestly think you will be okay, they are not as bright as I thought they would be. I have the 24" on a 20gal long with plants and am going to upgrade to something brighter. Hope this helps you.

They just keep growing. If you live in a cold area in the winter- important to protect the plant. they are a great plant and they work so nicely.

I have brought in for the winter due I got them August. To late to transplant. I have them under grow light .They are about 2ft high now.

It is designed to emit light at specific wavelengths which the human skin is sensitive to and is lacking in the sunlight spectrum during the winter due to clouds and short daytime. Your typical neon/fluorescent tubes and CLF bulbs do a poor job of emitting these specific wavelengths of light, they were designed to light up a room at minimum cost and not stimulate your skin. As if that isn't enough, you're also indoors, so your sun exposure is minimal during the winter. These bulbs are a decent substitute, they are worth the money, I would buy them again. They won't give you a tan, but they sure help--a lot!

The more light, the better. I have had to keep mine inside all winter and none of the windows get a ton of light so the succulents have stretched out looking for light. The cactuses seem to do ok with less light but grow bigger and look healthier with more. We kept them on the porch all summer where they got tons of light but were sheltered from rain and just watered biweekly. They seemed happy with that.

Hello, I used this product for indoor where there is not much sunlight. I am sorry that I cannot provide you informative detail.

I really don't understand your question. The LEDs won't give you enough light for normal lighting. You should use the white and blue Florescent together for plant growth and day time lighting. I only use the LEDs for a night light.

That's exactly what I did (and eggplants). I have used a fluorescent light in the past. With this light, the plants grew less leggy and more upright. Visibly better plants this year. I cannot address the comments that the light decreases in lumens over time. For this season I saw no difference over time. The light was about 12" - 16" above the plants and each covered about a 12" square of plants. I had 1 lamp and the flats were about 20" long. I simply flipped the flats 180 degrees once a day and all seemed good. Hope that helps.

I don't see why that would be a problem. They aren't like florescent bulbs that need to stay warm or take forever to warm up if they're cold. LED's don't care much about ambient temperature.

I am using it to grow herbs indoors. It seems to provide less light to the plants compared to normal sunlight. My belief is that vegetables might fare worse than the herbs (basil and parsley).
