AC Infinity Hydrone 3 Plant Dehumidifier

Stop letting unpredictable humidity compromise your harvest. The AC Infinity HYDRONE 3 is a smart plant dehumidifier engineered to automatically maintain the perfect environment in compact grow spaces. By precisely controlling the Vapor Pressure Deficit (VPD), it ensures your plants can transpire efficiently, leading to faster growth, better nutrient absorption, and healthier yields.

Designed specifically for spaces up to 2'x2', this unit is the ideal companion for an AC Infinity 2'x2' grow tent. It features a high-precision 10-level PWM motor for stable, fine-tuned humidity regulation and a dual-port design that allows you to duct dry air directly into your tent. For ultimate control, it seamlessly integrates into the AC Infinity UIS™ ecosystem, allowing for advanced automation when paired with controllers like the Smart Controller 69 Pro.

FAQs

What size grow space is the HYDRONE 3 designed for?+

The HYDRONE 3 is specifically engineered for compact grow spaces, making it ideal for grow tents up to 2'x2' in size. It's a perfect fit for the AC Infinity Cloudlab 722 tent.

What is VPD, and why is it important for my plants?+

VPD stands for Vapor Pressure Deficit. It's the difference between the amount of moisture in the air and how much moisture the air can hold when saturated. Maintaining an optimal VPD range allows plants to 'breathe' (transpire) efficiently, which drives nutrient uptake and accelerates healthy growth.

Can I connect this dehumidifier to a smart controller?+

Yes, absolutely. The HYDRONE 3 is part of the UIS™ platform and can connect to an AC Infinity smart controller. This allows you to access advanced automation, scheduling, and remote monitoring through the AC Infinity app.

How does the dual-port system work?+

The unit has a rear exhaust port that allows you to duct the dry air directly and efficiently into your grow tent. It also includes an optional intake port, which enables you to create a closed-loop system for maximum efficiency by drawing humid air directly from the tent.

What if my grow space is larger than 2'x2'?+

For larger spaces, AC Infinity offers more powerful models. We recommend considering the HYDRONE 5 for tents up to 3'x3' or the HYDRONE 7 for tents up to 4'x4' to ensure optimal environmental control.

Where can I learn more about setting up my grow environment?+
