A board fixture for a 3x3 indoor plant layout

The AC Infinity IONBOARD S33 is a full-spectrum LED grow light board made for a 3x3 grow tent or a similarly measured indoor plant area. It uses Samsung LM301H diodes and hangs above seedlings, herbs, vegetables, or flowering plants.

This style of fixture works through planning. The gardener names the growing footprint, checks the frame, chooses a hanging height, and keeps the cord route dry before the plants move in.

Built around hanging height and dimming

The S33 format gives the plant area one broad overhead light source. That makes a level hanging path important, because the fixture should sit squarely above the canopy.

Dimming gives the setup a practical control point. Seedlings, herbs, and leafy growth can sit under a schedule that matches the plant stage, fixture height, and room conditions.

Good match

This light fits gardeners setting up a 3x3 tent, a dedicated indoor vegetable corner, a herb station, or a seed-starting area with a sturdy overhead support.

What to know
