Customer photo review of Pianta Grow Light LED Bulb

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.

Customer photo review of Pianta Grow Light LED Bulb

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!

Pianta Grow Light LED Bulb

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.

This grow light got my monstera to produce its first split leaf in three years!

Pianta Grow Light LED Bulb

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

Pianta Grow Light LED Bulb

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.

Customer photo review of Pianta Grow Light LED Bulb

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.

Frequently Asked Questions

Product Usage & Setup

How long should Pianta grow lights be on for?

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.

How far should LED grow light bulbs be from plants?

The Light should be pointing directly at your plants. Be careful not to keep the light too close as it can burn the plant, between 0.3m - 1m is a good distance to start with, then move as required. Keep an eye on your plants as they will give you feedback. 

Refer to our blog for more guidance!
