We designed our LED panels to be as simple as possible to install.
To do so, we made them compatible with a widely used standard called VESA.
VESA is initially made to hang screens against walls, the holders are cheap and available virtually anywhere.
VESA holders are usually made of two parts, one is attached to the wall (the base), and the other is attached to the led panel.
Place the led holder base at the middle of the top shelf with one hand, and mark the position of the holes with a pen.
Using the mark done previously, make 2 holes, watch out that the drill is the right size for you screws (ie. the screw should be slightly larger).
Get help from your buddy to screw the LED holder's base in place.
Now take the other part of the led holder, the one that goes on the led panel.
You can use zip ties or screws to attach the led holder to the led panel.
Attach both parts of the led holder together, and add the tightening screw.
And you're halfway good to grow.
