    • Works great!

      I plan on buying a second one as soon as my budget allows for it. I've already jumped started a bunch of seeds, comparing them to ones I started at the same time outside. The ones indoors are 33 to 50% larger, and germination rate is near 100%, even for some that have a lower germination rating from the seed supplier! One recommendation is for the design. I'm already looking at a way of stabilizing the light/hood to the frame as it can swing when moving it and is a bit top heavy, depending on where you have the light height set.

    • Grow Light

      This grow light is great. My only complaint is the plug does not stay in well. All and all I really like it and now have plants in my garden thriving from starts under my grow light.

    • excellent seed growing system.

      Easy to set up and works wonderfully. It was a better price than anything I could find and fits two planters underneath not just one.

    • Great for Winter Indoor Gardening

      So, this would be a five star review if the assembly had been a bit easier, and one of the feet on the legs hadn't broken. In spite of those two minor problems, I love the product. You can easily fit a large earth box under the light and you might also be able to fit two junior earthboxes. Also good for growing seedlings. Works with a three prong timer from the local hardware store.

    • 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.

    • 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!

    • 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.

    • 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.
