Do You Even Need One?

If your brightest spot is a north window or a dim room, a grow light turns "surviving" into "thriving" for sun-lovers.

What to Buy

A full-spectrum LED panel or bulb is the sweet spot: low heat, low power, and the right colour for plants. Look for a high PAR/PPFD rating and a colour temperature around 5000–6500K (daylight).

How to Use It

  • Place it 15–45 cm above the canopy.
  • Run it 12–16 hours a day on a simple timer.
  • Raise it as the plant grows to avoid leaf scorch.

Frequently Asked Questions

Q: Will any LED bulb work?

A:

Only full-spectrum plant bulbs; ordinary room bulbs lack the right wavelengths.

Q: How long each day?

A:

12–16 hours; more is not always better.

Q: Does it replace a window?

A:

It supplements; a bright indirect window plus a light is ideal.
