Heat source ?

I use a cheap honeywell heater with a built in mechanical thermostat. I find them to be a bit more reliable than the digital. Just requires a bit of tuning in to the desired temp at the beginning. Honeywell HZ-1350C..... ...... I have one sitting in my nursery tent and it's keeping temp stable @ min 23 degrees. Turns off automatically during the day when tent is heated to 25 degrees with heat produced by the LED light. Cycles at night to keep @ 23.

Hi Showmethewaytogrowhome ! Si la temperatura de tu habitación supera los 15-16 grados, puedes introducir aire a la tienda de cultivo con un pequeño ventilador. Junto con esto, le proporcionas a la tienda de cultivo una salida de aire para conseguir un flujo de aire renovado. Suerte con la cosecha.
