Good as the more expensive competitors *by M***K on 21 June 2022* This controller works like a charm. Absolutely accurate and it couldn't be easier to set up. Numbers are large so you can see them and the co2 remote detector has a green light so it doesn't disturb light cycle of plants. $100 less than the leading brand and works just as well! ## Frequently Bought Together - CO2 Controller Carbon Dioxide Controller CO2 Meter Monitor Day and Night Relay Function, NDIR CO2 Sensor for Green House, Grow Rooms, Factory, Home, Office - EDYCARX 25ft 1/4" CO2 Drilled Tubing, Black PU, Grow Room CO2 Injection System, Kit Includes Tubing, Fittings & Accessories, Compatible with CO2 Regulator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/422721816-co2-controller-carbon-dioxide-meter-monitor-day-and-night-relay](https://www.desertcart.sg/products/422721816-co2-controller-carbon-dioxide-meter-monitor-day-and-night-relay) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-17*
