Propagation Luminaire LED Horticultural Fixture Reviews
✮ ✮ ✮ ✮ ✮ Great light for plants Great light, bright, plants love it -Kindle Customer 10/20/20
✮ ✮ ✮ ✮ ✮ Highly recommend! This light is exactly what I wanted for my hydroponic microgreens. The quality is great. I highly recommend! -Elizabeth Kim 10/19/20
✮ ✮ ✮ ✮ ✮ Great quality Love these lights -tanya 10/15/20
✮ ✮ ✮ ✮ good Good -alex 08/22/20
✮ ✮ ✮ ✮ 99.9% plug n play. Housing is plastic, but solid while light. Fixture hangs level easily with included factory affixed foldable metal loop (like on a picture frame) Packaged well with well thought out educational literature/brochure The only issue I had, was one of the jumper cables to wire in series didn’t work. I will definitely be buying more Of these lights. There are cheaper options but all require some diy rigging and a light meter and some engineering. If you aren’t super handy or experienced in the sweet science of light and you like a clean aesthetic in your production setup then this is the best option I’ve found. -iofstorm 08/12/20
✮ ✮ ✮ ✮ ✮ Great Deal for LED Grow Lights & Best packed shipment I have seen in a long time This two-lamp package has already started to revive my wife’s house plant rack. They are bright and easy to hang. All parts were there. Many of the Prime products I buy are pretty minimally packed for shipment but not this one. Box within tough air-tube wrap within another box inside a shipping box. They arrived without a bit of damage and the container would probably survive an 8 foot drop. I would definitely buy these lights again. The plants look great under these lights. -Dennis H. 03/20/20
✮ ✮ ✮ ✮ ✮ Highly recommended lights Thoughtfully made, sturdy, and works great for chaining banks together. My orchids are putting on new growth and really seem to be thriving indoors with these lights compared to the blurple lights I used previously. -malhomme 02/22/20
✮ ✮ ✮ ✮ ✮ Works well for clones Good light -Beth 11/13/19
✮ ✮ ✮ ✮ ✮ I highly recommend these lights! I’ve been using these lights for 3 years now. I have a total of 8 so far, and I’m very happy with them. I use them in a succulent shelf set up, an orchid shelf, and as supplemental lighting in my sunroom. I’ve attached some pix of the succulents and the vandas -all the plants seem to be thriving. The sunroom gets enough light on a sunny day, but here in PA sometimes weeks go by without one, so these lights come in handy there as well. I’ve kept my citrus trees and tropical hibiscus out there over winter for 2 consecutive years now without an issue. The lights are on anywhere from 8 to 14 hours a day depending on the time of year, and so far have not had any bulbs burn out. There were a few issues with the lights themselves, mostly from being banged around during shipping. Amazon and Active Grow replaced the lights without question. Active Grow customer service is amazing as well. They are fast to respond and super helpful. I highly recommend these lights! -Jojot 10/24/19
✮ ✮ ✮ ✮ ✮ FInally the right light for my greenhouse! Outstanding customer service. The light is really bright and warm, and the unit is relatively small and unobtrusive, easy to install. -Jurgen Braungardt 10/18/19
✮ ✮ ✮ ✮ ✮ Solid Veg Light So far so good. I bought this light for an aquaponics garden. My cucumbers, strawberries, bell peppers, and green onions have all started off with rapid growth. I will use this light through fruiting to really test it. Will update when all is said and done. -09/28/19 Amazon Customer
✮ ✮ ✮ ✮ The price was right! Taylor at Active Grow was very helpful! We’ve been reading a lot of research on LED lights for growing seedlings and wanted to experiment this year. We have them above our tomato seedlings and they’re looking real good. They were easy to install. Taylor at Active Grow was very helpful with information about placement etc. -Joan M. Guglielmino 03/16/19
✮ ✮ ✮ ✮ ✮ Outstanding Product This product is performing as expected and has been a great addition to my new urban farm startup. It is perfect for growing microgreens and shoots-among other things. I have already ordered several more since my first purchase. The lights are simple to set up and to use, lightweight and sturdy construction. You can daisy chain up to 5 units which is a huge plus. I spent a lot of time researching which grow light would be optimal when considering my production goals and finally settled on this product. The owner was also very helpful and assisted me with my questions. Overall the company, Active Grow, gets high customer service marks in my book for being responsive and very helpful. I would highly recommend this product to other growers interested in a cost-effective, quality grow light. -Amy Brown 01/27/19
✮ ✮ ✮ ✮ ✮ Outstanding for Orchids I am a serious orchid grower, and have created several indoor growing areas using LED lights. Right now, I am using LED grow lights from six manufacturers … and Active Grow is my favorite for seedlings, Paphiopedilum, Phalaenopsis, and other lower light orchids. I do have some medium light Dendrobiums starting to flower under the Active Grow lights as well. I had hoped to replace my T5 HO fluorescent bulbs in the fixtures over my Paphiopedilum seedlings with conversion LED bulbs like my others from Active Grow. However, the conversion bulbs didn’t work in those ballasts. Since I had such great results with the light spectrum from the Active Grow LEDs with my blooming size Paphs, I decided to simply replace three of my 108W T5 fixtures with the 40W Luminaire product. Very, very pleased with the decision.
In a nutshell: better light quality, much less energy, and much less heat. The latter has been very beneficial for the recently deflasked orchid seedlings — the surface of the pots don’t dry out as quickly and stress the small root system. We have about 150 orchid seedlings currently under the Luminaire fixtures, and dozens more mature orchids growing (and flowering) under their conversion T5 LED bulbs. Everything has been an upgrade with these LED lights for the orchids — I can’t think of any downsides. The orchids are happier, and therefore, so are we! -A’na Sa’tara of Ancient Energy Orchids (www.aeorchids.com) 01/02/19 -Read more about her experience working with Active Grow LEDs and others on her website here.
✮ ✮ ✮ ✮ ✮ Quality Light Excellent product for growing Microgreens and other plants indoors. I did extensive testing of this light and was very happy with it. This light produced Microgreens at a rate and quality equal to lights that used a lot more electricity. By saving on electricity this light will pay for itself quickly.” -Corey from Corey’s Cave 06/23/18
✮ ✮ ✮ ✮ ✮ One light grows 4 – 1020 trays of microgreens. Varieties of pea, sunflower and radish I was hoping one of these lights would grow 4 trays of microgreens in a row and i was correct. Microgreens look lush and delicious. Add in the 3 year warranty and since electical savings will cover the cost of the lights over that time, I’d say its a home run. It seems the lights a bit close together in the fixture. Not sure if Active Grow decided to do this for a reason or not but I am very pleased with my order. -Brad 07/26/18
