FAQs

What size grow tent is the Ionboard S33 best for?+

The Ionboard S33 is specifically designed to provide optimal coverage for a 3' x 3' area, making it a perfect match for the AC Infinity CLOUDLAB 733 grow tent. For larger spaces, consider the AC Infinity Ionboard S44.

Is this light suitable for all stages of plant growth?+

Yes, absolutely. The Ionboard S33 provides a full-spectrum output (660nm, 730nm, 3000K, 5000K) that supports plants through their entire life cycle, from seedlings to flowering. You can use the dimmer to adjust intensity for each phase or automate it with a compatible AC Infinity controller.

What does the IP65 rating mean for a grow light?+

The IP65 rating signifies a high level of protection against environmental factors. The '6' means it's completely sealed against dust, and the '5' means it can withstand low-pressure water jets from any direction. This makes the Ionboard S33 exceptionally durable and safe for use in the high-humidity conditions common in grow tents.

What is the actual power draw?+

The Ionboard S33 has a true power draw of 240 watts at 100% intensity. The amperage varies by voltage: 2.30A at 120V, 1.15A at 240V, or 0.97A at 277V. The built-in dimmer allows you to easily reduce power consumption for younger plants or different growth stages.

How can I get the best results from my AC Infinity setup?+

For optimal performance, pair your Ionboard light with other AC Infinity components to create a fully automated environment. Integrating inline fans, clip-on fans, and controllers allows for precise climate control. For a detailed walkthrough, check out our in-depth guide on AC Infinity setups.
