Smart, even heat for reliable growth
This 540 W PTC ceramic heater is engineered to maintain optimal growing temperatures in grow tents and indoor gardens. A dedicated Spider Farmer sensor plus an adjustable 160 cm flexible duct continuously monitors and regulates the environment, reducing temperature fluctuations and seasonal stress for steadier VPD around the clock.
Built for hobby and pro growers
-
Precise control, fewer swings: Zone-based regulation with built-in dead-zones and PWM control delivers fast yet stable heating.
-
Multiple operating modes: Heating mode, Fan mode, 24 h timer and four customizable temperature settings — plus day/night profiles for consistent climate.
-
10 heat/fan levels to fine-tune by tent size and season.
-
Four-level safety: Thermostat hardware protection, internal and ambient over-temp protection, and flame-retardant materials for safe operation.
-
Plant-friendly & quiet: Duct directs warmth slightly above the canopy; auto-sleep display (30 s) prevents unwanted night light.

Practical grow tips
-
Aim the duct just above the canopy to avoid localized drying.
-
Slightly higher day temps with lights on, lower at night to save energy and stabilize the environment.
-
Dial levels according to room temp, tent volume and airflow.
