USB LED Grow Light for Indoor Plants
Impossible de charger la disponibilité du service de retrait
Most plant shelves have one thing in common: a single outlet far from where the plants actually are. A clip-on light needs a desk edge. A panel needs a mount. A grow bulb needs a socket. The USB LED Grow Light strips all of that away plug it into a power bank, a laptop port, a USB wall adapter, or a phone charger, bend the metal gooseneck to the exact angle your seedling tray or propagation shelf needs, and the light is on in under 60 seconds without drilling, clamping, or rearranging anything.
The light bar holds 21 full-spectrum LEDs emitting across the phyto wavelength range at 5V low enough to run continuously from any USB source without heat buildup, strong enough to support germination, vegetative growth, and flowering cycles for compact indoor plants, seedlings, and hydroponic trays. The included flexible metal gooseneck extension positions the bar at any height and angle, turning a single USB port into a fully adjustable grow light station that moves whenever your plants do.

Where it works best ?
Seedling germination trays :
Bend the gooseneck flat above the tray at 4–6 inches. The bar's horizontal format covers a full row of cells evenly no hot spots, no shadowed edges. Plug into a power bank for portable tray setups that move between rooms.
Hydroponic and water propagation setups :
Position the bar along the back wall of a propagation station or hydroponic shelf at 6–8 inches above the water level. The 5V USB power works from the same strip as your pump no second outlet needed.
Small indoor pots on desks or windowsills :
Plug into a laptop USB port and angle the gooseneck over a succulent or herb pot on your desk. When you move to another room, the whole setup unplugs and relocates in one motion no remounting, no recabling.
Mini greenhouses and grow tent supplementation :
Line the bar inside a mini greenhouse shelf where panels can't reach the back corners. The slim bar format fits where no clip-on or panel light physically fits, filling the photon gaps that cause uneven canopy growth.
