Spider Farmer® 540W Smart Grow Tent Heater with Hose & Sensor

The Spider Farmer® 540W Smart Grow Tent Heater provides precise, grow-safe climate heating engineered specifically for indoor grow tents, greenhouses, and drying rooms. Low night-time temperatures and seasonal cold snaps disrupt plant metabolism, cause nutrient lockouts, and slow flowering growth. Using advanced PTC ceramic heating plates and Pulse Width Modulation (PWM) technology, this 540W unit delivers stable, energy-efficient warmth across 10 adjustable heat and fan speed levels, eliminating dangerous temperature swings and keeping your canopy in its optimal growth zone year-round.

Designed with plant safety in mind, the unit features a 160 cm extendable, heat-resistant vent hose that directs warm air into target areas without blowing hot, dry air directly onto delicate foliage. An ultra-responsive built-in temperature sensor probe tracks environmental changes faster and more reliably than standard external probes. Connected via an RJ12 cable to Spider Farmer GGS Controllers or via the smartphone app, growers can set custom Day/Night temperature schedules, mimic natural daily temperature cycles, and automate heating triggers remotely.

Safety is paramount in enclosed cultivation spaces. Built from flame-retardant materials exceeding V0 and 5VA standards, the heater includes four layers of hardware and overheat protection. Additionally, the unit serves as an essential companion during post-harvest drying, working alongside dehumidifiers to supply controlled, gentle warmth and airflow that accelerates moisture reduction while preserving valuable terpenes and flower quality.

Key Benefits:

• PTC Ceramic & PWM Technology: Delivers rapid, energy-efficient heating across 10 customisable heat and airflow speed levels.

• GGS Controller & Smart App Integration: Connects via RJ12 port for full remote smartphone control, custom timer schedules, and automated target temp triggers.

• Natural Day/Night Temperature Simulation: Automatically transitions between day and night temperature settings to support healthy plant metabolism and crop yields.

• 160 cm Targeted Vent Hose: Flexible, anti-ageing hose routes warm air into target grow space zones without causing direct windburn or leaf drying.

• Grow-Safe Construction: Four-layer safety protection with flame-retardant casing exceeding V0 and 5VA standards, built-in overheat hardware shut-off, and low-wiring sensor probe.

• Post-Harvest Drying Support: Works in tandem with dehumidifiers to maintain stable warm air circulation during crop drying phases.
