What is a Grow Bar?

Grow Bars are all-in-one grow lights kits made for your plant shelves, Ikea cabinets, book shelves and under cabinets. They emit a bright, white, full-spectrum light to give your indoor jungle the extra light they love, without the burn. 

Perfect to brighten up lower light areas all year-round or as a light boost to get through winter. Ideal to supplement natural light for variegated plants, for propagating houseplant cuttings and baby plants, as well as all your indoor plants that prefer bright, indirect light.

Grow Bars are designed for indoor plant hobbyists venturing into the often confusing world of grow lights for the first time. providing a budget-friendly kit, including built-in timer.

"Love these little grow lights. They're light and very easy to install just about anywhere. They have more features than I was expecting. My Monstera Minima is sprouting new leaves and shoots. We are both very happy." 
Jay Dee ⭐⭐⭐⭐⭐

 What's included in the kit? 

Both Grow Bars measures 33cms long and this kit comes with two Grow Bars included (two bars connected to one controller and one cord / timer / plug).

These kits are very much 'plug and play' with no fancy set-up or assembly required. The USB cord is compatible with standard USB to NZ plug adaptors, not included.

Kit includes

• 2 connected Grow Bars with full-spectrum, white* LED light chips.
• 1.8 metre USB power cord,
• In-line controller with 3 timer and 4 brightness settings,
• Screws or strong, self-adhesive tape for attaching to shelves**

*Colour = warm end of white (see product photos and review photos)

** You can also use cable ties or plant velcro (not included), if you want a less permanent solution for attaching them compared to the tape or screws (included).

The 2 Grow Bars can be used in-line for longer shelves, or up to 55cms apart for attaching to multiple levels or shelves.

The power cord (which is 1.8 metres long), splits into two cords (one to each light) and the cord length from the splitter to the light is 55cms. 

Everything comes neatly, safely tucked up in its box, shown in the photos. These lights don't come with directions and are very simple to use but you can come back to check this page for the directions if you're unsure (or email me). Plant shelves and any plants shown are not included. 

Built-in timer settings

The timer button (the button with the clock on it), can be used to set a 2 hour, 4 hour or 8 hour timer. You can also use these lights on manual on/off. When you press the timer button, a light will show that matches the colour of the time you selected.

2H written in green on the controller means 2 hours and a green light will turn on.

4H written in blue means 4 hours and a blue light will appear when selected.

8H means 8 hours and a red light will appear.

Once set, the light will stay on for the selected time. It will turn off 2 or 4 or 8 hours later. Then turn on again at the time it was set the next day.

If you manually turn the lights off (using the controller or at the wall), you'll need to manually turn them on and set the timer again.

Please note: The same as all grow lights with built-in timers, these are not compatible with external plug timers. For that you want the Sansi bulbs combined with a compatible lamp.

 The sciencey stuff (and what it means for our plants) 

Combined you have 10 watts and 5 volts for low energy consumption, with 48 LED full-spectrum chips per bar, with a light wavelength range of 380 to 780 nm.  Nm stands for nanometers, which measures the wavelengths of the light produced. 

Plants require light in the 400 to 700 nm range to photosynthesize, known as PAR (Photosynthetically Active Radiation). It's not the brightness (how it appears to us), but the PAR that matters to our plants.

Full-spectrum doesn't mean sunlight. It refers to the CRI or Colour Rendering Index being over 90, meaning the light produced is much the same as how we see colours in our natural world lit by daylight.

What adaptor is needed?

A 1A USB to NZ plug adaptor is the minimum needed, but a 2A would be better. You should find 1A or 2A printed on your adaptor to double-check.

NZ Warranty

Grow Bars have a 6 month warranty which I extend a further 6 months to one year in NZ. As a customer I've always hated the hassle and awkwardness of returns, so as a business I make it as fast, friendly and hassle-free as I can for you in the unlikely event anything goes wrong, plus I cover all costs when a return is covered by the warranty (applies to NZ purchases and use within NZ only).

The warranty covers manufacturing faults or defects with the lights (not the adaptor plug), meaning it covers most things you did not cause or could not prevent, either intentionally or by accident. More about returns >
