Keeping them at the day and night temps I need. I will be a happy camper if I get them to bloom Review: Easy to set up but needs uk plug - Had to replace the plug top for a uk as it was supplied with a US plug, it's dual voltage despite the heater not displaying this info on the heater but the manual does confirm it. They have used a flex which doesn't indicate too easily which side is the Live or Hot as our US friends know it but a quick Google search helped me identify the conductors polarity enabling me to wire the UK plug. After this I simply plugged it in, connected to the ggs controller and it just started to run to environment settings I had already pre set. Very happy with it :) Delivery was about a week which is good considering it's journey ## Features - NEW Tent Heater: Different from the regulation of fixed temperature, the grow heater adopts temperature zone regulation design with built-in dead zones 3 (set temperature -3°F on, heating to +3°F off), avoiding frequent switching on and off, and providing more stable temperature control and peace of mind for plants.

Sensor readings update every 10 seconds and may be affected by airflow.Allow a few minutes for the temperature to stabilize. **Q: Why doesn’t the heater respond after I select a mode?** A: The settings are only saved after the screen blinks three times. If another button is pressed too soon, the setting may not apply.After any change (including Day/Night mode), wait for the blinking to finish before pressing other buttons. **Q: What if the operation feels too complicated?** A: A detailed user manual is available on the Amazon product page.You can also contact our professional support team for assistance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great heater *by D***R on 16 October 2025* My banana plants are toasty warm.
