Spider Farmer 540W Grow Tent Heater – Smart PTC Heater with 24H Timer, Day/Night Mode & GGS App Control

The Spider Farmer 540W Grow Tent Heater is a powerful, energy-efficient PTC grow tent heater, specially designed for grow tents and professional indoor growing environments where stable temperature control is crucial for optimal plant development.

During cold periods, winter nights, and dry spells, this smart heater prevents temperature drops, minimizes plant stress, and supports a consistent microclimate. With 10 adjustable heating levels, automatic temperature control, and full GGS app integration, this system offers professional climate control for serious growers.

This is not a standard heater, this is a smart climate element for controlled indoor cultivation.

Smart PTC Heating with 10 Power Levels

The integrated PTC ceramic heating technology combined with advanced PWM control ensures fast, stable and safe heat output.

• 10 adjustable power levels (L1–L10)
  
• Automatic power adjustment in AUTO mode
  
• Constant temperature without extreme peaks
  
• Energy-efficient heat build-up
  
• Fast response to temperature drop

PTC technology prevents overheating and increases safety in closed grow tents.

Day & Night Mode – Natural Temperature Simulation

The integrated Day Mode & Night Mode mimic natural temperature fluctuations between day and night, which is essential for:

• Healthy metabolic activity
  
• Optimal transition between growth phases
  
• Stronger flowering development
  
• Reducing winter stress

A stable temperature profile means less growth retardation and more consistent yields.

Full GGS App Integration (RJ12)

This heater is fully compatible with:

• GGS Controllers
  
• GGS AC5 Power Kit
  
• GGS AC10 Power Kit

With the Spider Farmer App you can:

• Control heating remotely
  
• Set 24-hour schedules
  
• Automatically control the target temperature
  
• Program smart heating cycles
  
• Synchronize climate with ventilation and LED systems

Please note: The heater must receive continuous power to be recognised by the GGS system.

Fully integrated climate control = maximum stability.

4 Smart Operating Modes

• Manual Mode
  Direct on/off control with a choice of 10 power levels.
• 24H Time Window Mode
  Set start and end times with selected heating level.
• Cyclic Mode
  Automatic heating and pause intervals.
  For example: 1 hour heating / 1 hour break.
• Temperature mode (AUTO)
  Automatic power adjustment to maintain set target temperature.

Integrated Precision Sensor

The professional built-in Spider Farmer sensor:

• Measure temperature in real time
  
• Responds faster than external sensors
  
• Automatically adjusts heating level
  
• Reduces cabling
  
• Increases reliability

This ensures precise climate control without external accessories.

Even heat distribution

The included 160 cm flexible hot air hose :

• Distributes heat evenly throughout the grow tent
  
• Prevents direct heat on plants
  
• Protects against dehydration of leaf surface
  
• Resistant to deformation and long-term use

Ideal for medium to large tent setups.

Professional Safety (V0 & 5VA)

Designed with safety as a priority:

• V0 & 5VA flame retardant materials
  
• Multiple overheating protection
  
• Automatic shutdown in case of risk
  
• Auto screen-off after 30 seconds
  
• Suitable for long-term use in closed environments

Safety + reliability = worry-free heating.
