LED Grow Lights

The right light grows the plant. Our Grow Lights are efficient LED bars that give indoor crops the spectrum they would get from the sun. They suit seedlings, salad leaves, herbs, tomatoes and chillies, and run at a low cost through the year.

Choose a full-power LED for main growth, a gentle propagation bar for cuttings and seeds, or the dimmers and drivers that tune a light to its job. The brands here are Sanlight, HortiONE and G-Bars.

About Our Grow Lights

Plants need light to grow, and indoors that means an LED grow light. A good one gives the full spectrum a plant uses, without the heat or running cost of older lamps. We stock Sanlight EVO and Flex, HortiONE and G-Bars bars, rated from 10 Watt up to 400 Watt.

Pick the wattage to suit the area you are lighting. A small propagation tray needs a 10 to 20 Watt bar. A full 1m² cabinet of fruiting plants wants 300 Watt or more.

Why We Added This Range

"Lighting is where growers waste the most money, usually by buying far too much wattage. Match the light to the job. A gentle Flex bar is perfect over seedlings, while a strong EVO earns its keep over tomatoes and chillies in flower."

— Matt, Founder of Greenhouse Stores

💡 Tip: Hang the light at the height the maker advises, then dim it for young plants. Too much light too soon bleaches tender seedlings.

Frequently Asked Questions

  • Which grow light do I need?

    Match the wattage to your growing area. A propagation bar suits seedlings; a full-power LED suits fruiting plants in a cabinet.

  • Are LED grow lights cheap to run?

    Yes, LED draws far less power than older grow lamps. It also runs cooler, so the growing space stays easier to manage.

  • What can I grow under these lights?

    Salad leaves, herbs, microgreens, tomatoes and chillies all grow well. Lower-watt bars are best for raising seedlings and cuttings.

  • Do I need a dimmer?

    A dimmer helps but is not essential. It lets you lower the light for young plants and raise it as they grow, which protects tender seedlings.

  • How high should a grow light hang?

    Follow the maker's stated height for the model. Hanging too close scorches leaves; too far and plants stretch and go leggy.
