This particular light is well-made and has four replaceable bulbs. The packaging is outstanding and all arrived well, intact, and undamaged when received. I did break one of the bulbs when taking my setup down after springtime planting and I haven't had much success finding "grow light" replacement bulbs at my local hardware store, but finding a 24" T5 that will fit in a pinch shouldn't be too hard. Speciality garden shops may have the 6500K bulbs, or you can pick these up non-Prime on Amazon from several sellers.
Heat mats and proper lighting are the key to consistent and prolific germination of seeds started in late winter to be ready for springtime planting.
Here's the setup I've used for the past few years:
-Park Seed Park's Double Bio Dome with 80 Jumbo Cells. I actually use 2-18 Jumbo Cell for a total of 36 plants. There are several sizes of the Bio-Dome system. I have the DOUBLE Bio-Dome which allows for two seed starting cells (Purchased from Park Seed)
-Hydrofarm MT10008 20-by-20-Inch Seedling Heat Mat (Purchased from Amazon)
-Hydrofarm FLT24 2-ft/ 4-Tube T5 Commercial System with Bulbs (Purchased from Amazon)
-Hydrofarm MTPRTC Digital Thermostat For Heat Mats (Purchased from Amazon)
-Style Selections 36-in H x 24-in W x 18-in D 3-Tier Steel Freestanding Shelving Unit (Purchased from Lowe's)
The modular, adjustable wire shelving unit gives me the foundation for my indoor winter seed-starting setup. The shelves are adjustable so that I can hang the grow light on the underside of the top shelf, then adjust the middle shelf so that the top of the Bio Dome is about 6-8 inches from the light. This allows for enough room to remove the top of the Bio Dome in the event I need to access the plants for watering, fertilizing, etc. The bottom shelf is great for storing my remaining planting supplies.
The light is almost the same size as the Double Bio-Dome and provides 100% light coverage necessary for young plants to thrive. A few years back, I tried to use a light that was only 2 bulbs and half the size of the one I currently use. You could tell that the young plants would angle toward the light hanging in the middle, and those on the outer edges didn't grow as quickly and tall as those in the middle. Take it from someone who spent $25 - $50 each year over the course of several years trying to find a light that would work well with my seed starting system. I knew about the Hydrofarm light early on, but wasn't too eager to purchase it due to it's higher cost. I wish I would have gotten it first because I would have saved money in the long run considering the poor-performing lights I purchased in years prior to getting the one listed above.
The Park Seed Bio Dome is an extraordinary seed-starting system that allows your plants to grow quite large without root binding problems found in other tray-type seed starting setups. Park uses the styrofoam cell matrix with replaceable organic bio-sponges in which the seeds are planted.
I regulate the temperature of the seed heat mat with the Hydrofarm MTPRTC Digital Thermostat set at between 85-90 degrees. This thermostat has a temperature probe you can insert into one of the organic bio-sponges to obtain a direct soil reading. I route the probe through one of the vent holes in the lid of the Bio-Dome.
In order to capture the most heat from the heat mat, while allowing the thermostat to regulate the temperature of the mat, I first take a folded beach towel and place it on the middle shelving rack. I then set the heat mat on top of the towel, then place the Bio-Dome on top of the heat mat. This allows me to recover most of the heat that would otherwise radiate from the exposed, bottom side of the heat mat.
Watering with the Bio-Dome setup is easy and, depending on how you have the vents adjusted in the lid, performed infrequently at best due to the efficiency of water vapor recovery of the Bio-Dome system.
I typically start tomato and pepper plants in mid-February so that they are ready for planting by the first week of May. You may want to check online for your indoor planting and outdoor transplanting dates depending on your region and climate.
I hope my sharing with you what has worked quite well for me will help you in your seed-starting endeavors!
I will say I had a bit of a learning curve with it. For one I do not have all 8 lights on. I did for a while, but when I tried to start a second batch of seedlings in with the first, it scorched them as if I had put them in the July sun at full blast. It's fine to have all eight lights going as long as the second or third set of true leaves have developed, but until then just keep the outer four on. The ballast will reflect enough light on the rest.
Also, this light draws moisture from the soil quicker than what I had expected. Although I started with plugs I would recommend using a seed starting soil like fox farms. I was watering the plugs twice every day to compete with the heat of the light. People had recommended to keep the plants 2-3 inches near the light- don't. Scorched the leaves horrifically on some plants. 1-2 ft. is fine and my plants are not spindly at all. It does emit heat even for a fluorescent, so the distance and fan compensate most of your heat problems. The fan encourages stronger rootstock well so it's a win all around. It seems to be low energy, we never saw a spike in our electric bill so that is the biggest plus.
In summary great light, great price, and will keep using this product for time to come.
First, the build quality of this product is top notch. Some complained about bulbs breaking on shipment but I did not have this issue.
Second, the output on this light is incredible. I grow carnivorous plants which require lots of light to develop properly. I get deep red coloration and healthy looking plants from this fixture.
I've had this fixture since August 2012 and it still works and looks great.
If you want a high quality fixture for a great price, buy this fixture.
Overall, the quality is okay and the lights are bright and put off some heat but not enough to burn anyone. My first unit burnt out after 5 months but amazon replaced it so Kevin was only without his lights for 4 days. He was very happy to have them back as you can see in the picture, which was taken a few minutes after I plugged the lights in. I am sure he would give them 5 stars if he could.
I am giving them 4 since the first fixture was defective.
