Note: This product is not compatible with controllers or similar accessories from other brands. This product is specifically designed for customers aiming to achieve optimal growth results, particularly those using CO2 supplementation and high PPFD lights. It includes a temperature and humidity PPFD sensor that can replace the temperature and humidity day/night sensor in our GGS Controller Kits and GGS AC5/AC10 Power Strip Kits (please note that the “Temp Humi PPFD sensor” cannot be used together with the “Temp Humi Day/Night sensor” in the GGS Controller Kits and GGS AC5/AC10 Power Strip Kits — only one can be used at a time). The standout feature of this sensor is its ability to measure PPFD, as opposed to simply detecting light or darkness. Additionally, the product comes with a CO2 sensor and studies show that CO2 supplementation can boost plant growth rates by 20-100% on average and increase overall crop yields by 20-30%. When CO2 is added, using high PPFD lights further enhances
