    • Worked for a week
      Verified Purchase

      Light went out within a week. Thought it might be a damaged bulb and eventually bought another. Still never worked.

    • Great little unit I can move to any location.
      Verified Purchase

      I use this to catch the "overflow" from starting seeds indoors during the winter. I like that I can raise and lower the light. I'm pleased with the purchase.

    • Works well, but...
      Verified Purchase

      I learned the hard way that when you have some seedlings growing faster than others, leaving the one bulb one height is difficult, so you need to raise one side higher than the other so that everything gets the proper amount of light at the same time. I ended up buying a new system with multiple bulbs so that the slower growing plants can have the light at the proper level while the taller plants can also have their taller light at the proper level. It's good bough if u have all the same crop under the light that grows at the same rate

    • So Excited!!
      Verified Purchase

      This little system was easy to set up and is functioning as described, although it's quite a bit bigger than I thought it would be and not that that's a bad thing. I added a heated mat underneath to keep them warm and now I am so excited watching these little plants come up.

    • Exactly what I wanted!
      Verified Purchase

      I did a lot of research before buying this system. It arrived securely packaged, assembled quickly and functions simply and easily. Most importantly, my seedlings this year are the healthiest I've ever started. I am very pleased with this purchase.

    • Sturdy Stand, easily assembled
      Verified Purchase

      I am a 67 year old grandmother and was able to assemble this by myself following the directions in under an hour. It took me a few minutes to realize I had to remove the blub and pull off the foam holders that protected the blub from jostling and then replace the blub before it would light. I have been using it for 6 days and have seedling sprouting.

    • Hydrofarm Jump Start Grow Light System 4'
      Verified Purchase

      I originally purchased one of these a few months ago from a different web site and was so happy with it that I decided to order another one and thankfully Overstock.com had it in the lowest price range that I was looking for. I was pleasantly surprised that the stand was a little taller than the 1st one that I bought and the lighting system works well allowing me to start my vegetable garden seeds indoor early. Otherwise I would have to wait until May to plant my seeds given the long New England winters. I liked this system so much that I purchased one for my brother-in-law, for Christmas, who is also an avid gardener.

    • A good little light
      Verified Purchase

      I set up the grow-light and ballast and purchased 2 trays of Jiffy starter squares and some organic 'strating' soil. I also purchased a timer and have the timer programmed to have the bulb running 18hrs a day. The sprouts are coming out very quickly and easily overtook the plants I placed outdoors almost two weeks earlier. I would recommend that if you have the indoors, get a "space" blanket to put over the light and ballast system because the light is very strong. Happy growing!

    • Nice Grow Light
      Verified Purchase

      For some reason I thought there would be two bulbs in this light. However, I think the grow light is good. It is what I expected otherwise. If I were to buy this again, I think I'd buy two 2-foot grow lights instead of this long one.
