I already have a few different grow bulbs. But this one I decided to buy your pianta bayonet bulb to see how it would work in my lounge ceiling fitting ( which does hang low). It arrived today and it works perfectly! I have plenty of tropical plants, fish , cats and myself who will enjoy having a spot in the sunshine throughout winter, on those dark days. Many thanks. Quick delivery, well packaged and thanks for the free e-book, lots of useful information 😁
Im Gegensatz zu der Vergleichspflanze, die am selben Tag umgetopft wurde aber in einem Fenster ohne Grow light steht, sind meine Hoyas unter der Pflanzenlampe kräftiger und haben bereits neue Blätter ausgebildet.
Good
Schönes Leuchtmittel, schnelle Lieferung, vielen Dank
Great grow light!
Love this grow bulb, it arrived swiftly and safely and is like a work of art, beautiful! It casts a gorgeous warm light and is perfect for creating an ambient mood in addition to supporting plant growth.
Perfect lights to nurture my seedlings before being moved outside in the sun.
Great long lasting grow bulbs, always buy from them.
Love my pianta bulbs, they look stylish but my plants love them more, the amount of new growth since using the bulbs us phenomenal. Really happy 😊
Best grow bulbs around!! Turned my plants into giants and now I have a proper jungle.
tut was es verspricht, sehr hell
Schönes warmes Licht, passt in jede günstige E27-Fassung.. bin sehr zufrieden:)
My indoor plants are flourishing well with all the light.
So happy with my grow light! I thought my poorly calathea was for ready for Compost Heap Heaven but since being under the pianta bulb for just a couple of weeks she has one new leaf and a whole new shoot. One very proud plant mumma, thank you Grow Gang!
The bulb is great and is now keeping a few of my plants alive in a dark corner. Initially I received a bulb that was partly broken (due to rough handling in the shipping I suspect), and when I raised this with grow gang they immediately sent me a new one. I would highly recommend them and their products to anyone wanting to grow plants that need more light even in dark corners of their homes.
Very effective light for some rare tropical plants we have.
Lovley lights, been a couple of weeks and my plants absolutley love them!
This grow light got my monstera to produce its first split leaf in three years!
Dem Gummibaum geht es seit der neuen Pflanzenlampe deutlich besser 👍🙏👌
Great bulb..my once shady corner in now thriving
Our ginormous monstera has to sit in the middle of the room due to her size so we bought this for winter and drizzle days (often) and she is thriving had new growth in one week. What a fantastic idea! Install was so simple so really pleased with this purchase, will be getting more for the others!
The bulb fits in my existing lamp fitting! And works really well so now when I have my lamp on in the evenings my plants get all the light they need too
It gives off a really lovely bright sunny daylight glow.
I live in a small eighteenth century cottage that has small windows, hence there is insufficient light to allow my houseplants to grow well. The Pianta grow bulbs provide enough light to encourage the plants to grow and flower, even in the darkest corners. The bulbs are reasonably priced and delivery is swift.
BEST LIGHT EVER
Gave a second chance to some of my dying plants during winter.
All the dark corners of my home are now alive with plants, thanks to my Grow Gang grow lights . . .im de-light-ed with them 🙂
This is my Monstera Compacta (Kunzo) it was received as an unrooted top cutting in September 2025. It was rooted on and left to establish itself under the Pianta grow light. This is its second newest leaf in that time, more fenestration/splits meaning it's happy with the amount of light provided by the lamp. Without it, the plant would have more than likely struggled due to lower winter daylight. Absolutely delighted with the products, I have the clip on lamp holder as well as one adjustable floor lamp and another on the way. Best things ever.
In just a few weeks I have new growth on my weeping fig. It kept dropping its leaves in a north facing room and now it’s happy as Larry without spoiling the look of my room.
Loving the grow light, helped my plants to be happier in shaded areas in my house. Fitted in my lamp, so I’m very satisfied with it.
Great light. Im using it in a standard light fitting further into my apartment as its already light & it looks great. Plants enjoy it as much as me.
Second grow lamp purchase from here, great product, great service, good value
Great lamp. Does the job
So happy! My plants are happy too! 🪴🪴🪴
Great!
Amazing lamp! Seedlings and plants are loving life. No heat coming off it and it is not a blinding light. Highly recommended.
Great bulb. Very high quality and plants are reacting to it very positively
Looks elegant but helps plants as well
Great investment
Just 2 weeks in and the plants are already looking happier and more verdant!

This will depend on the type of plant you are growing and on how much natural light your plants are getting. As a rough rule of thumb to effectively mimic the sun's natural light it should be on for 8- 16 hours a day however if there is already a lot of natural light, it can be used for just a few hours a day to top up the light and keep the plant thriving.
Even plants need a good nights sleep! Make sure not to run the light for longer than 16 hours a day so your plants can rest.
The light should be pointing directly at your plants. Be careful not to keep it too close, as too much light can stress your plant. A good starting distance is between 0.25m - 0.9m, then adjust as needed. Keep an eye on your plants—they’ll give you feedback.
Refer to our blog for more guidance!
