Description

PlantSpectrum emits all wavelengths that contribute to plant growth. Results at every stage of growth, for every type of plant. Sustainable lighting design is all about smart and effective passive cooling. PlantSpectrum’s aluminium housing prevents the LED chips from overheating. This in contrast to plastic housings where the heat remains inside and generates bubbles on the phosphor layer of the LED chips and damages the LED’s irreversibly. We designed an extrusion profile that increases the cooling area up to 26 times. The profile is open and constantly transfers the heat away from the PCB board resulting in optimal cooling efficiency. Thanks to its unconventional circular design, PlantSpectrum is the cleanest among growlights and is perfect for laboratories or clean grow spaces as no dust stays behind between heat sink grooves. PlantSpectrum is cleaned with a single wipe. Strength of light is typically measured in Lux. Yellow light is more sensitive to the human eye, so the more yellow light, the more Lux. However for plants this is almost the opposite. Plants are more sensitive to red and blue. Therefor, they can not be measured in Lux. Light strength for plants is measured in PPFD, Photosynthetic Photon Flux Density. Or simply said, the density of the light flow that results in photosynthesis. Therefore the output of grow lights should be measured in PPFD, while Lux only indicates the strength of the grow light to the human eye. DLI stands for Daily Light Integral, and indicates the total amount of energy the plant needs on an average day. This depends on the total amount of hours of light you give to the plant, the distance the light source is placed from the plant and the strength (PPFD) of the light source. You can find more info for specific plants and how to light them in our plant database.

Best grow light ever
Love this grow light, super minimal and goes with my aesthetic. Customer support was super responsive and helpful. I would buy this again and then some.

Good quality light
Made of aluminium so magnets can’t help to stick or attach it to metal cabinets No timer function but easily solved by paring with smart plug No intensity option but still very good My plants are doing well with them

Good for foliage, not strong enough for flowering tropicals
It’s not that I don’t like these lights, I just wish they were more powerful. I have purchased multiple lights from this brand and been using them for almost 2 years. I love that they’re simple, well-made, and they look beautiful (more like polished lighting that belongs in a home and less of the ‘industrial warehouse’ vibe most plant lights on the market have). They work well for growing foliage and they eventually get certain plants to flower, but they are not strong enough to get my tropicals to flower. When I started finally supplementing them with Barrina lights (orb grow), I quickly saw a difference and some of my plants that were exposed to barrina lights started shifting into a bloom cycle. The only plants that did flower were a small citrus and a flowering vine within a foot of 2 of these lights, and a succulent growing right next to it for almost a year was so starved for light that it reverted to green and became leggy (after a few days of Barrina light, it started changing to its expected color). If you are only growing foliage plants this is an aesthetically pleasing, well-made light, but this is going to be insufficient if you’re looking for rapid growth or to flower a high-light tropical. I also REALLY don’t like how cagey Mother plant is about the stats on their lights that are important to know for growth; they are really not transparent about this and their website has a lot of waffle. ... show more

Awesome Light that plants adore!
I own 2 different sizes, this being the larger of the 2. Constructed incredibly well and very nice spectrum offering in its class. Versatile and easy to install into a variety of uses. Can be setup horizontally or vertically with the supplied base. Only complaint I have is I use it installed to the inside roof of my IKEA Ruudsta greenhouse cabinet and it does put out a more heat than my other lights in my other cabinets. You need to take this into consideration if using in an enclosed space and accommodate or retrofit. It will throw off your VPD numbers and possibly overheat the cabinet if your Ambiant temps aren’t consistent and controllable in the coming summer. It raises temps 5-10°. ... show more

Pictures and Sundews plants LOVE it.
This is the must have lighting system to grow plants. There is a book that will tell one the required distance from the source to get the correct lighting. My three units are on Smart plug WIFI, timer. All my carnivorous plants love this lighting. This system is worth the funding and will show growth quickly. This is the company to use. ... show more

Best growlight! Mimics the sun
Review Image by Christine Moon
One of my fiddle leaf fig cuttings finally rooted with this grow light. With how gloomy it’s been, it has been super difficult getting my plants to grow and bloom but this growlight has been a lifesaver! I love that there’s multiple options to use this light - standing or mounted. Having a titanium outer shell is great too since I can just replace the bulb. Oh also it has two different color lights - a cool and warm hue which is nice! 10/10! Must-have ... show more

Very weak light and very overpriced
I purchased two of these lights and am honestly very disappointed. I installed them on the undersides of my plant shelves and noticed they seemed quite dim. The Mother website provides recommendations for several plants on how far they should ideally be placed away from the grow light. I have a calathea ornata, so I looked up that plant and the recommended distance from the plantspectrum32 was 50cm. According to their website, at 50cm, the PPDF of their light is 22, which is super low. Definitely a lot lower than what would be necessary for this plant to thrive. So I emailed Mother directly about this and got a response from the founder. To summarize, he said it's not enough light for the plant on its own, and the distance recommendation is based on the assumption that the plant is recieving ample natural light. I calculated the DLI provided by this light and compared it to what was listed on the Mother website as optimal for this specific plant, and it came out to about 18% of the plant's light needs. I presented my calculations to the founder and he acknowledged that they were correct. I dont know about you, but if I'm using a grow light, it's typically for plants located in spaces where the ambient light is drastically less than what the plant needs to thrive - not a spot where 82% of their needs are met by ambient light. For my shelves, I ended up supplementing with several strips of cheap Amazon grow lights, and now the PPFD on those shelves is respectable, but still not ideal. Definitely don't waste your money on these very overpriced lights. There are WAY better grow lights out there at a fraction of the price. ... show more
