    This review is from: Hydrofarm JSV4 4-Foot Jump Start T5 Grow Light System (Lawn & Patio)

    Just received and assembled this product today. I’m not sure why others have posted about poor quality and flimsy construction of this product. I am very satisfied with the construction and sturdiness. This product is exactly what I expected for the price, product description, and pictures.

    I did notice that there are 3 very similar hydrofarm 4 foot grow systems listed on amazon, with a $15 price-range difference. This is the most expensive of the three. The only difference I can tell from the written description is that this product is described as having a premium light fixture. The pictures look the same. One of the other 4 foot hydrofarm systems received a few positive reviews.

    Assembly required a philips head screwdriver, pair of pliers, and about 5 minutes of my time. One screw is used to connect each of the two vertical supports to the base cross-bars. Due to the shape and construction of the parts, this fit is tight and secure. Then each of the vertical side bars slips into the top piece (metal button is pressed and then releases into a hole on the top piece). Then you attach the light fixture itself, by hooking nylon string with s hooks attached to the top to either end of the light fixture. Pliers are used to close s hooks. The light is raised and lowered with the nylon string, very similar to a heavy venetian blind. It would be nice if the nylon string were a tad thicker, but it is sufficient for the job.

    Overall, I am very happy with this product and would recommend it.

    I have some mixed feelings about this product, even though I’m about to order a second one. First, and the only downside to this light, the overall construction is rather cheap. The frame is rather flimsy…Hydrofarm put all their know-how into the most important part: The light itself. But be forewarned the frame is a bit wobbly. Since a grow light sits stationary most of the time, it’s not a serious issue. The two biggest plus points for this product.. the price and the fact that it works. I grow exotics and palms in zone 7 and have to overwinter them inside, and my Hydrofarm light has kept them going for 2 years straight. Unless you have the extra bucks $$$ to invest in the HP sodium or metal halide lights (as well as the increased energy usage) it would be hard to beat this bargain.

    Simple, light weight, easy to adjust light, February 9, 2008

    I have had this light set-up for a few years now, and still love it. The original fluorescent fixture conked out after 2 or 3 years’ use, but a $10 shoplight fixture from a hardware store replaced it seamlessly. The stand is very light, and slightly aggravating to put together the first time, but it does the job beautifully. It is the easiest to adjust of all lighting systems I’ve used, allowing one-handed movement of the light up or down, making it great for seed starting. The one-handed-ness is made possible via some coiled metal strips within the cross-bar that create tension on the two strings or chains that connect to the sides of the light fixture. If you have to remove the fluorescent fixture for bulb replacement or storage, I recommend that you hook the two strings or chains to one another to avoid having to reassemble the tensioning mechanism, which can be annoying.

    This, plus a few heat mats and a small fan on a timer are all I’ve needed to start and grow thousands of strong seedlings in my tiny apartment, populating the neighborhood with flowers and veges for years now!
