    • Exactly as shown

      Well made, lightweight and can be easily moved, fairly easy to put together even though directions are a little confusing. Use the picture on the box to help figure it out. Nice product for reasonable price.

    • Exactly what I wanted!

      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

      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'

      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 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

      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

      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.
