T5 HO 4FT 4 Tube Grow Light Fixture Reviews

✮ ✮ ✮ ✮ Beautiful Light and Very Helpful Customer Service
Active grow was very valuable in helping me to choose the right light for my orchid growing stand — great customer service. I am very pleased with the appearance of the full spectrum light — my orchids appear very natural. I am looking forward to seeing how the higher light levels improve my growing environment. -Hilary 06/24/19

✮ ✮ ✮ ✮ ✮ Top notch light, a worthy investment
These lights are well-made, bright, and have a nice illumination spectrum — power consumption is put into useful wavelengths, whereas a fluorescent bulb wastes a lot of energy emitting light that is not useful to plants. These bulbs give off some heat, but not much; plants can grow happily within 1 or 2 inches of the bulbs, which also allows you to maximize the amount of photosynthetic production versus power consumed. My plants love them! I have been running them for almost a month now & am very pleased. I will aim to update later on. -Brendan 06/21/19

✮ ✮ ✮ ✮ ✮ The Best Full Spectrum Grow Lights Made!
I HAVE TRIED THEM ALL IF YOUR LOOKING FOR THE BEST THESE ARE THE ONLY ONES! I’m getting 99.5% germination excellent vegetation and amazing flowing. Our yard has never looked better. Staring flowers from seed and bring them to planting size as well as bloom. Starting vegetables from seed for our green houses with these lights has increased our crop 300%! -John Glover 06/15/19

✮ ✮ ✮ ✮ ✮ Robust light!! – You immediately see the difference in spectrum
I have tried the 2 bulb hood combo, the 4 bulb red bloom, and this sun spectrum. Overall – they are all perfect in there own use and cycle. The sun spectrum is my favorite. We use all of them in a agricultural research environment. We focus on germination and early stage growth…Bottom line… these are superior to all forms of light we have used for germination and vegetative growth.We do a lot of comparisons and a/b testing… I love the consistency of these LEDs. I will post some pictures as soon as I can. I had some issues that were clearly an issue during shipping… after I notified them- they sent me replacement parts – I also noticed after that…on my next order… the packaging was even more robust.. So awesome when a brand goes above and beyond to solve an issue…and then prevent it from future occurrence…awesome awesome. -Phoenix 04/24/19

✮ ✮ ✮ ✮ ✮ Great Orchid light
I love this fixture! I replaced my 2 ft fixture with this 4 ft/4 tube fixture for my expanding orchid collection. I have very happy plants now! This was easy to hang and set up and i’m sure will last me many years. There is the option of lighting 2 or 4 bulbs. This would allow bulbs of different spectrums to be switched out if needed. -Sybil 04/17/19

✮ ✮ ✮ ✮ ✮ This light is great!
This LED light came very well packed for shipping. It provides excellent light and my tomato plants are very happy! -Sherry 04/12/19

✮ ✮ ✮ ✮ ✮ NICE LIGHT
This is my first grow light purchase, out of the box the light was easy to put together and hang. I read a lot of reviews before I bought this and they all seemed positive. -CWSD 04/12/19

✮ ✮ ✮ ✮ ✮ Great grow light!
This lamp is great! I live in zone 4 so I have a short growing season and these lamps are a game changer. The light tubes and fixture are built well. –Andrew B. 03/25/19

✮ ✮ ✮ ✮ ✮ Great lights for a hobby greenhouse
These lights work great. Still growing cool weather vegetables in January and supplementing heat with a small milkhouse heater. -Elizabeth Parks 01/07/19✮ ✮ ✮ ✮ ✮ Worth it!
I just started growing my own lettuce on Nov 4 2018. I did a bunch of research before buying lights, but still ended up with several types. I have a 2’x 8′ space growing 36 plants. Half have been growing under normal T5 fluorescent lights, and the other half have been using the Active Grow T5 LED lights. The fixtures are the same. The only difference is the lights, and the plants can tell. The plants under the Active Grow LED lights are noticeably larger than those under the fluorescent light. I also find the color to be more vibrant. I liked the performance and cost savings of these bulbs so much, I bought a second set to replace the T5 Fluorescent lights I mentioned above. I just received them a couple of days ago, and they are up and running now. I love the power savings too! I can run two, 4′, 4 bulb, Active Grow T5 LED setups for less than the cost of one 4′, 4 bulb T5 Fluorescent setup. I’m definitely producing lettuce cheaper than I can buy it in the store, and it’s always clean, healthy, and picked fresh daily. -Mitchell Hickok 01/05/19 ✮ ✮ ✮ ✮ ✮ Best LED grow light that I have used … the orchids are thriving
All grow lights are not created equal — it is no small feat to successfully replicate the natural sunlight that plants have evolved with for eons. What looks bright and pleasing to humans is not necessarily what is most valuable to plants (for photosynthesis). I’ve found this out through trial and error, and a lot of research, to enhance my orchid growing. At the moment, I count six different LED grow lights in operation for different types of orchids, using LEDs for both supplemental and sole sources of light. I’m taking the time to write a review, which I rarely do, because the Active Grow LEDs are the best full spectrum grow lighting that I’ve found so far for orchid seedlings, and blooming size Paphiopedilums and Phalaenopsis. I particularly note the robust year-round root growth on the Paphs, including multi-floral and higher light species. I run my lights 9-10 hours/day — which has been plenty for flowering the lower light Paphs, and fewer hours than I comparably used T5 HO fluorescents. I’m also trying some higher light species under the ActiveGrow lights as well. The near blooming size Dendrobiums are growing well, with a few flowers emerging on the largest seedlings. I also note that recently deflasked orchid seedlings do not dry out as quickly under these LED lights, compared to the T5 HO fluorescents. This is very beneficial given their shallow root systems, and many of the smaller seedlings are establishing more easily. -A’na Sa’tara of Ancient Energy Orchids (www.aeorchids.com) 01/02/19 -Read more about her experience working with Active Grow LEDs on her website here.

✮ ✮ ✮ ✮ ✮ The light works well!
I have grown kale, carrots, lettuce, arugula and cilantro so far with great success! -Sue 12/23/18

✮ ✮ ✮ ✮ ✮  In another league, way to go ACTIVE GROW!!!
Hands down the best T5 ever!!! Micro greens are ready in 2 days under these lights instead of 3, in 3 days I have a 25% increase in weight, and my purple kale tastes even better, the quality is unmatched. -Buyorsell 12/08/18

✮ ✮ ✮ ✮ ✮  Perfect light for your indoor garden
I am impressed by this light. It was easy to assemble and mount. The led’s lights produce virtually no heat so I can grow my plants anywhere without having to worry about ventilation. It’s compact size does the same job as my bigger lights. My baby plants are doing good so I know the spectrum is what it’s suppose to be. -P Muniz 09/05/18

✮ ✮ ✮ ✮ ✮  Game Changer
I’ve been using T5 HO lamps for a while now as my primary light source. I thought I had my spectrum close to dialed in with a mix of different lamps. I had my doubts. I decided to switch over to these T5 HO daylight LEDs and was quickly blown away by the response in my garden. Deeper greens, thicker leaves, tighter growth patterns, everything. The PPFD reading is much more even throughout the ENTIRE grow space as compared to my experience with traditional T5 HOs. I can now utilize the edges of my grow space instead of just focusing on the direct center under the lamps. Literally EVERYTHING is so much better then traditional T5s that I’ll never go back again. The spectrum these lamps produce has been a total game-changer. Thank you Active Grow. -04/30/18 Todd 

✮ ✮ ✮ ✮ ✮  High-light orchids are blooming!
After having tried unsuccessfully to grow Cattleya orchids in my sunroom, I decided to convert an unused sauna in the basement to an orchid grow room. Did a lot of research on T5 both fluorescent and LED and bought these. They were expensive but I determined that they would be cost effective over 3+ years. I was persuaded by the fact that the have a CRI (Color Rendering Index) of 91. That was a statistic I could understand. These are truly full spectrum. There is a lot more information on the company’s web site. An interesting video that compared these to T5HO. I really swallowed hard before buying these because of the higher price. The video provided information on the quality and quantity of useful (to the plant) lights that these put out. I understand it better now, but the proof of it is what I am seeing in the plants.

I now (for the past three months) have these on 16 hours a day in my small room. They do produce some heat but far, far less than T5 fluorescents, which would have been a disaster (I see now) in my enclosed room. With two fans running and lots of humidity (trays, misting, wetting the concrete floor) I can keep the humidity high, the temperature where I want it (by keeping the door more or less open), and the air quality fresh. OK, but — what about the plants? I am now seeing the first buds on one of the Cattleyas, and most of the orchids are pushing new growths and roots. Even in my unskilled hands, the life force that I am seeing in these plants is just –truly awesome. I measured the light and it is about 1800 foot-candles very close to the lamps. Because they are on continuously for 16 hours a day, the plants are getting ample light, the rough equivalent of 3500 foot-candles in a natural environment where light waxes and wanes throughout the day. I can control the amount of light by locating the plants closer or farther from the lamps. I could never have had a setup like this with fluorescents because the heat would have never allowed me to put the plants so close to the lamps as I can with these, and the room would have been too hot. (Opening the door further would let heat out, but would also let humidity out). I have the full spectrum bulbs in all three fixtures but am anticipating trying out some of the red bulbs once we get into bud-producing season in the fall.

For the first time I can grow and flower high light orchids like Cattleyas. I am already thinking about how I may be able to install a fourth unit in the grow room. I am running out of space. -Tessa 08/05/18
