Who This Is For

  • You are adding lighting to a tight shelving unit because your current setup produces hot spots that damage the canopy.
  • You are switching to a single-controller kit because managing individual power cords for each bar creates cable chaos.

What We Found

  • The included 29.6-inch extension cables are the real win here, since they give you actual room to space out the bars.
  • The mounting kit is surprisingly complete, so you wont need to run to the hardware store for extra clips or tape.

What Users Say

  • Propagators who switched to these bars say they finally have uniform growth across every tray on their rack.
  • Users who rely on the built-in timer report that they no longer stress about leaving lights on during off-hours.

Vivosun T5 1ft Full Spectrum LED Grow Light Bar | 4-Pack

Getting consistent light coverage across a compact seed starting shelf shouldn't require multiple controllers and tangled cables. The VIVOSUN T5 1ft Grow Light Strips 4-Pack delivers full-spectrum 5000K output across all four bars at 7W each — 28W total — with a single timer and dimming controller, so every tray gets the same quality of light without any extra hardware.

The compact 1ft form factor makes this kit ideal for small propagation trays, multi-tier shelving units, and tight spaces where a longer bar simply won't fit. Three 29.6-inch extension cables let you space bars exactly where coverage is needed, and the included mounting hardware — screws, wall anchors, clips, and double-sided tape — gives you multiple installation options on any surface.

Whether you're germinating seeds on a kitchen counter or running a small dedicated propagation shelf, the T5 1ft 4-Pack lets you dial in photoperiod schedules and light intensity from a single controller, so you can fine-tune conditions for each stage without swapping hardware as your setup grows.
