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

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.
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!
It has pros and cons. I have looked for similar products in this price range, but this one seems to be pretty unique. I have not been able to find another product which is a complete set with a stand, full-spectrum fluorescent bulbs, and a fixture for under $100.
As such, it seems like there is not much competition for this type of product in the marketplace. It shows - the product could be better.
First, it is not very sturdy. The metal frame requires assembly, but the pieces are soft (mine arrived bent and I had to use pliers to reshape it before I could complete the assembly). The frame, once it is assembled, is not terribly sturdy. Even for something in this price range, I was disappointed with the quality.
There are two fixtures for fluorescent tubes. The tubes do not lock into the fixtures very well, and have a tendency to shift and roll around. The metal pieces which contains the fixtures can flex and deform, which contributes to the instability of the tubes.
One of the light fixtures on the product that I received was defective (I knew because I could switch the bulbs, but each bulb would only light if it was in the working fixture). The retailer I bought the product from (7GIFTS) and the manufacturer were excellent about getting me a replacement fixture - both were very communicative and seemed happy to address my problem. That was a plus.
I have the light on a timer, set to provide ~18 h of light per day to my succulents and some flowering plants that require full sun. All in all, it works well - the plants are doing nicely.Read more ›
