Upgrade from manual climate adjustment to intelligent VPD management.
The Mars Hydro Smart VPD Kit helps you monitor and maintain a stable grow tent environment with automated humidity control. The sensor tracks real-time conditions and sends data to the Mars Hydro app, allowing you to view temperature, humidity, and VPD levels from your phone.
Set your target humidity based on your plants’ growth stage, and the connected humidifier or dehumidifier automatically adjusts to help maintain optimal conditions for healthier growth.
Add the 15L Auto Refill Kit for continuous water supply, allowing your humidifier to run longer with less manual refilling.
Simple RJ12 Connection

• Enhanced PPFD Uniformity for 2x4 Grow Tents
Optimized optical layout ensures even PPFD distribution across every corner of a 120x60cm grow area. Eliminates hot spots and weak zones, allowing plants to grow uniformly with consistent light intensity.
• Premium USA Bridgelux Diodes
Built with high-efficiency Bridgelux LEDs for stronger output, higher penetration, and improved energy savings. Reliable performance for growers seeking stable, long-term lighting quality.
• Bar-Style Cooling + Waterproof LED Protection
Bar-style structure offers superior heat dissipation compared to board lights, maintaining lower operating temperatures and longer lifespan. The exclusive waterproof LED casing protects diodes from water or nutrient splashes—ideal for humid tent environments.
• Perfect Fit for Personal Indoor Growing
Designed specifically for home growers using 2x4 tents, providing efficient 300W output, lightweight installation, and optional smart control when paired with the Mars Hydro controller.
The Mars Hydro VPD Control Kit combines a humidifier, dehumidifier, and 15L auto refill system to help maintain more consistent humidity throughout the plant growth cycle. The humidifier and dehumidifier work together to balance moisture levels, while the auto refill system continuously supplies water to the humidifier, reducing the need for frequent refills and daily maintenance. By keeping humidity more stable, the kit helps create a more consistent environment for plant growth and provides a solid foundation for maintaining stable VPD conditions.
For Smart VPD Control, add iControl to monitor real-time temperature and humidity, view calculated VPD data through the Mars Hydro app, and automatically manage compatible equipment according to your target conditions.
