The metal pieces are not as poorly constructed as I was led to believe despite the fact (drumroll) it was made in the People's Republic of China. Shocker. But the apparatus I found to be quite stable. The metal pieces are thick and durable. The pieces do come together a little bit haphazardly. You *may* need a rubber mallet to get some of the pieces to stick into each other, which interlock with plastic connectors. Just a little bit of plastic was shaved off due to the tightness. The alternative would be much less desirable, so I don't mind.. I don't plan on taking it down anytime soon. Otherwise I needed no tools at all to assemble.
The pulley string seems a little bit poorly engineered, but having said that it still works perfectly and still seems rather "well" made considering the price and country of origin. The light is super bright, which will make my indoor plants happy this winter and may even take up more permanent residence as I am currently in a location with little to no direct sunlight.
I cannot yet attest to the growth factor of the light itself. I will be sure to update with this information when it is time.
The construction, materials, and appearance suit me perfectly so I am happy with this purchase.
[UPDATE] So a few months after purchase and consistent (but not constant) use, I noticed a faint buzzing sound, similar to that of.. well, any electronic light buzzing sound. It wasn't so bad, but then one day it became really LOUD. Annoyingly loud. This annoyingly loud buzz remained for another couple months, then one day it just went away and became silent again like before. I speculate if it were interference from the neighboring apartment, but moving it around the room doesn't seem to interfere with it. I will say, I've had this for months now and the original light still shines bright and my plants are damn happy.
[UPDATE] The buzzing came back again, and when it is loud it is almost unbearable like having a bee trapped in your eardrum. Two star loss.
[UPDATE] The buzzing got so bad, I could never leave it on when I was nearby. The light crapped out completely less than a year after buying it, and that is with it being on maybe 50% of the time. Bummer. I guess the bottom line is that it works GREAT for a while, but quickly deteriorates in performance. Maybe a good starter light for the aspiring green thumb, but not a good buy for those with professional *ahem* greenhouses.
It also comes with a 24 watt T5 6400k High output fluorescent bulb which is already installed upon arrival. The 6400k bulb is a very efficient low heat bulb which is designed to promote overall growth in the plant. Because it is a low heat emitting bulb you can place the light source a couple inches from the plants to prevent the loss of light.
This is not a complex system, it is simple and efficient. For the price it would be hard to find a package which comes with a stand, a reflective fixture, a good bulb, easy adjustment, and easy assembly. It is a good first step into the grow light world which is vast and and many times confusing. I also found that it isn't really that flimsy. The product isn't industrial grade but the light fixture is sturdy and so is the stand if you put it together correctly.
I will be growing venus fly traps when they arrive and I have researched grow light systems quite a bit. This system will only cost me $1.50 cents to run per month. The calculation can be done by taking the 24 Watts and dividing it by 1000 to get KW. Then multiply that number by how much the electric company charges per Kilowatt hour. That is the price it will cost to power the light for one hour. Then multiply that number for one hour by however many hours you will run it during the day. Then just multiply the cost of one day by 30 days and you have how much it will cost you to run the system for a month.
For example here is mine 24W/1000 = .024
.024 x .1484 (cost per kWh) = .0035616 cents per hour (less than 1 cent an hour). .0035616 x 14 hours = .0498624 dollars per day (about 5 cents). .0498624 x 30 = 1.50 per month. So my light run for 14 hours will cost one dollar and fifty cents per month. This is assuming that the light runs at 24 Watts per hour.
When I was shopping for grow lights online I found a very helpful website that includes a much better description on the Jump Start grow light and has a lot of technical and very helpful information on plant lighting. littlegreenhouse.com/accessory/lights2.shtml#jsfixture.
The website has a grow lighting guide and also contains the calculation above. It was by far the most helpful website when considering this purchase. It includes a good bit of information about the T5 6400k bulb and the Jump Start from HydroFarm.
