Built for Growers Who Start Strong

The HelioGrow™ 100W LED grow light delivers efficient full-spectrum output in a compact form factor—ideal for small grow tents, propagation shelves, and autoflower cycles. Built for uniform canopy coverage and reliable indoor performance.

Designed to support seedlings through flowering, the HelioGrow™ 100W provides a balanced full-spectrum output that promotes strong vegetative growth and dense flower development. Whether you’re growing herbs, vegetables, or autoflowers, this LED grow light delivers consistent plant-focused wavelengths without wasted energy.

If you’re searching for the best 100W LED grow light for small tents, shelves, or closet grows, this fixture offers uniform PPFD coverage across compact environments. Its efficient diode layout ensures even light distribution to reduce hot spots and shadowing.

The HelioGrow™ 100W produces powerful light output while maintaining lower heat compared to traditional HID lighting. That means easier environmental control, reduced cooling costs, and stable indoor grow conditions.

Integrated dimming allows you to fine-tune light intensity as your plants mature. Lower output for early vegetative growth, full power for bloom—no fixture swaps required.

Getting Started with HelioGrow

Getting Started with HelioGrow

Unbox and Inspect

Carefully unpack your HelioGrow™ 100W LED and confirm all components: fixture, hanging kit, power cord, and end caps.
Inspect the corrosion-resistant lens and diodes to ensure everything is clean and intact before mounting.

Mount at the Right Height

For seedlings, position your light 18–24 inches above the canopy.
As plants mature, lower gradually to 12–16 inches.
Use the included adjustable hardware to fine-tune your distance for even PPFD coverage.

Set your Intensity

Begin at the lowest dimming level for seedlings and increase brightness every 10–14 days as growth accelerates.
Autoflowers thrive on consistency — the HelioGrow™ 100W four-step dimmer makes light transitions effortless and precise.

Dial in Your Cycle

Set your timer or RJ-12 controller to maintain an 18–20 hour light schedule.
Autoflowers don’t need darkness to flower, but a few hours of rest helps roots strengthen and plants reset.
