Grow room automation starts with accurate data: a controller can only respond well if it knows the real conditions in your tent. Right now this collection holds the SMSCOM Temperature Sensor, an extra sensor for SMSCOM controllers that measures the temperature at the point that matters, for example at canopy height rather than near the fan. Placing the sensor correctly makes your fan and climate control more precise and avoids unnecessary speed changes. Keep it out of direct light and away from heat sources for reliable readings. Pair it with a controller from fan controllers or climate controllers, and read about fan controllers for grow rooms.
Questions & answers about Grow Room Automation
All growing questions →- Climate What is the ideal temperature in a grow tent? About 22 to 28 °C with the lights on, and no more than about 5 °C cooler when they're off. Read the answer →
- Climate What is the ideal humidity in a grow tent at each stage? About 65 to 80% for seedlings and cuttings, 50 to 70% in growth, and 40 to 50% in flowering, a bit lower toward the end. Read the answer →
- Climate What is VPD and how do I use it in a grow tent? VPD (vapour pressure deficit) combines temperature and humidity into one number that tells you how strongly the air pulls water out of th... Read the answer →
- Climate Do I need a climate controller, or is a thermo-hygrometer enough? A thermo-hygrometer is enough to start with. A controller is worth it once you want fans, humidifier and heater to react on their own. Read the answer →
