VABIRA VBR-100 Plus (PAR meter)
A handheld light meter, over Bluetooth, not a fixed piece of tent equipment. It's for knowing how much light actually reaches the plants and whether it's enough for the stage. The card on the connection screen only explains it to you: the actual setup is in GROW TOOLS, inside the app.
