Maybe you think about sunlight a lot, or maybe you're normal and you don't. Either way, understanding what plants actually need from light will help you get the most from your sun bulb. We've put together a few guides that make it all easy to understand.

• What type of light do plants need to grow? Covers the wavelengths plants use, what grow lights emit, and how light intensity is actually measured (it isn't lux).
• How much light do plants need? Covers light requirements for different plants and how to read the signs your plant gives you.
• LED lights vs. other grow lights — why LED is the only option worth bothering with.

We've also got a full FAQ, a blog library, and a Facebook community of over 1,000 gathera growers sharing progress updates on their growing adventures.

Different wall materials require different fastening devices. The fixings provided are suitable for concrete or brick. For timber studs you may not need the plugs. Fittings for plasterboard are available at most DIY stores. Always check there are no electrical cables hidden behind your wall before drilling. If you're unsure, seek professional advice.

mounting to the ceiling

1. 1Mark where you want your cable mounts using a pencil.
2. 2Check there are no electrical cables behind the wall or ceiling. Seek professional advice if unsure.
3. 3Use an M4 drill bit to drill four holes for your cable clips — two in the wall and two in the ceiling.
4. 4Push the provided wall plugs into the holes.
5. 5Place the cable mount flat against the wall plug and screw through the mount and into the plug.
6. 6Assemble the two halves of each cable mount by screwing them together.
7. 7Adjust the beam direction as described in the "hitting your target" section below.

mounting to the wall

1. 1Hold the wall bracket in position, find the right spot, and mark two fixing points with a pencil.
2. 2Check there are no electrical cables behind the wall. Seek professional advice if unsure.
3. 3Use an M4 drill bit to drill two holes at the marked points.
4. 4Push the provided wall plugs into the holes.
5. 5Place the wall bracket over the plugs and screw through the bracket holes into the plugs.
6. 6Adjust the beam direction as described in the "hitting your target" section below.

other mounting ideas

The cable develops a lot of friction when wrapped around surfaces, which means you can hang the sun bulb from existing features as long as they're structurally sound. We've hung ours from cabinet doors, bannisters, and ceiling ornaments. Wrapping the cable multiple times increases the friction and hold.

This is one of the things that makes the sun bulb so much better than other grow lights on the market — it's incredibly easy to direct exactly where you need it.

adjusting tilt

Rotate the light within its mounting to adjust tilt. It can point straight down or up to 135 degrees upward.

adjusting yaw

Yaw lets you swing the light left or right. Loosen the grub screw at the top of the light, reposition the cable to your desired direction, then re-tighten until the cable is secure.

adjusting height

Pull the cable through the ceiling plugs or wall brackets to raise or lower the light to your desired height.

adjusting beam angle

Twist the lens of the light to widen or narrow the beam angle between 15 and 50 degrees.

Putting your sun bulb on a timer is the easiest way to keep your plants happy. A consistent daily light schedule, the same on and off time every day, makes a real difference to how well your plants grow.

smart plug timer

The gathera smart plug pairs with the Smart Life app, letting you set and adjust schedules from your phone. Download the app at e.tuya.com/smartlife and follow the in-app instructions to pair your plug and configure a schedule.

mechanical timer — a simpler alternative

A mechanical plug-in timer works just as well and is often cheaper. You can pick one up from most DIY stores. Set the on and off times using the physical dial, plug your sun bulb into the timer, and you're done. No app, no Wi-Fi, no fuss.
