1) High PPFD + Full Spectrum

210 µmol/m²/s at 6" with a 120° beam. The 4000K White + 660nm Red combo covers everything from seedlings to flowering — great for herbs, tropicals, and leafy greens.

2) Auto Timer + Smooth Dimming

Run one light period or break it into two — whatever fits your routine. The light eases on and off gradually, so your plants get a natural sunrise and sunset instead of a jarring on/off switch.

3) Smart App + Auto Sun-Sync

Circadian Mode follows real local sunrise and sunset — no manual scheduling needed. The app also sends watering reminders and dialing in the right settings for whatever you're growing.

4) Freestanding + Adjustable Height

No clamps, no shelves, no fussing. Adjusts from 15.7" to 22.8" and stands solid on its own — perfect for floor plants, tight corners, or anywhere a clip-on just doesn't cut it.

5) Solid Build + Easy Setup

Takes a few minutes to put together, looks good once it's up. The stand doesn't wobble, the light runs cool, and the whole thing is rated for 50,000+ hours. Backed by a 1-year warranty.

    FAQ

    Q: I already have a window — do my plants really need this?

    A: Depends on the window. North-facing, blocked by buildings, or just weak afternoon light? Your plants are probably running on fumes. The G4 puts out 210 µmol/m²/s at 6" — enough to keep herbs, tropicals, and leafy greens actually growing, not just surviving.

    Q: Do I need the app to use it?

    A: Nope. Touch controller on the light handles everything — on, off, dimming. The app just layers on scheduling, Sun-Sync, watering reminders, and a plant database if you want it. Totally optional.

    Q: What is "Circadian Mode" ?

    A: Circadian Mode syncs your grow light with natural sunrise and sunset in your area—just like how plants grow outdoors.If your plants are near a window, it adds light before sunrise or after sunset when needed. If they're in a dark room, it creates a full day-night cycle. Either way, your plants get consistent light that follows the sun's rhythm instead of a rigid timer.This prevents common problems like leggy, stretched growth from too little light, and helps plants develop stronger stems and better flowering.

    Q: Is the stand stable?

    A: Yeah, it holds up fine on a flat surface. If it feels loose out of the box, the connection joint just needs a firm twist to lock in — it's tighter than it looks at first.

    Q: Will one G4 cover multiple plants?

    A: Best for one plant or a tight grouping. Got a bigger spread? A second G4 does the trick, or the G6 bar light covers more ground if you're working with a longer shelf.
