ABOUT THIS STRAIN:  

Narnia is the stimulating sativa-dominant cross of Jack Herer and Trainwreck. The leaves are tightly curled leaves and a rich shade of forest green with bright, vibrant yellow pistils. The surfaces of the bud are coated with glassy white trichomes, making this strain extremely sticky.

INSTALLATION NOTES:

This test consisted of multiple comparative tables using
(3) Dimlux 1200 W Boost fixtures over a 50 sf table against (5) FGI Lightpanel 500 W fixtures over the same 50sf table.  

2500 watts of LED vs. 3750 watts of HPS

GROWER'S NOTES:


LEDs produced a better product

Trainwreck crossed with Jack Herer is an outstanding commercial production cultivar.  Although normally a 9 week cycle, this cultivar has the power to produce over 20% THC and crushing yields in just 8 weeks.  Combining a “schwazzing” style and heavy light levels have proven to be a winning recipe for this cultivator.

The results show a 36% savings with the LEDs in the amount of grams per watt of energy used, a 10% increase in potency (22% vs. 20% for HPS) and overall a more appealing final product.

Big yields and big buds from this big, full spectrum fixture.

Trolmaster HCS-2 Hydro-X Pro Control System
Trolmaster
Trolmaster HCS-2 Hydro-X Pro Control System $ 2,374.00 $ 2,499.00
  10.1' Touchscreen Fully Customizable  Free Smart Phone App plus Web-base control system TrolMaster revolutionized environmental controller technology when it introduced the Hydro-X. The Hydro-X Pro continues the revolution with a 10’ touch-screen and a web-based software. The Hydro-X Pro is backwards compatible with all current Hydro-X control / device modules. It also provides greater flexibility and allows any plug-in module to be addressed to be whatever the user wants. The user can also set up each plug-in module to have multiple “conditions” that will activate the module, allowing for almost unlimited control options. The Hydro-x Pro is designed to be a single room controller for reliability and ease-of-use. The Hydro-X Pro expands the capability of the original Hydro-X by allowing up to 50 sensors and up to 50 separate control modules to be connected to a single Hydro-X Pro. Multiple sub-zones can be created within the single grow space by linking a specific sensor, to a specific control function(s).The new 4-in-1 sensor comes with a LCD screen which provide the ease of onside monitoring. Customized programming allows almost limitless degree of control. Each of the variables (Temperature, Humidity, CO2, Light) can be controlled independently, meaning a customized ramp-up / ramp-down can be used to closely simulate natural outdoor conditions, or simply allow complete customization of the environment. Displayed on an easy-to-read and construct “graph” it allows the user to have 100% control of their environment. Another powerful feature of the Hydro-X Pro is the built-in calendar and calendar presets that allows the user to schedule an entire crop’s “recipe” within the Hydro-X Pro. All settings including Lighting, Temperature, Humidity, CO2, and Timers can be specified by the user as they “build” their multi-week crop schedules. Reminders can also be programmed to ensure critical tasks are not forgotten. The TrolMaster APP will also allow for notifications with separate day/night limits to be received by the user. The web-based software provides easy access and more advanced remote control. Onboard data acquisition and the ability to store and share setting between multiple devices, means that user-defined programs & settings can be saved and loaded into multiple Hydro-X Pro units with ease. A personalized screensaver page can be uploaded through a USB port. The same upgradeable feature like Hydro-X gives you the ability for life-time improvements. Included: 1x HCS-2 Controller 1x MBS-Pro Sensor 1x Mounting Plate 1x RJ12 Cable Set

Trolmaster
TrolMaster Hydro X Plus HCS-3 Grow Room Controller $ 1,195.00 $ 1,199.00
The Hydro X Plus / HCS-3 system is a professional-grade single-zone environmental control system that can control your entire grow space. It has an 800x480 7” LED display monitor and can control an unlimited number of lights, 8 temperature devices, 8 humidity devices, 4 CO2 devices, and 12 programmable timer devices (up to 50 schedules can be created). With incredible flexibility and the expanded product capacity, anyone can now easily customize their own grow room control system for maximum yields. Having multiple control modules also provides the option for the user to create multiple "stages" of growth. By staggering the start times of each stage, the user can minimize the amount of time that plants spend in vegetative growth and focus on the flowering phase. Having multiple control modules also provides the option for the user to create multiple "stages" of temperature and humidity control, which will provide a more stable environment. The HCS-3 system comes with an MBS-PRO 4-in-1 sensor to measure temperature, humidity, CO2 ppm, and the presence of light. Lighting control has never been easier or more capable. The optional MBS-PAR light sensor can be added to the system. It will automatically adjust light intensity to precisely provide the exact amount of illumination for optimum plant growth. The Hydro-X Plus has been can also track your DLI levels. Having 2 separate lighting control channels allows the user to create multiple lighting layouts (and dimming sequences) based on their individual preferences. Besides controlling your room, if a problem is detected by the HCS-3, a warning message (notification) will be sent to your smartphone. Up to 10 smoke detectors and 10 water leak-detectors can be connected to the HCS-3 which will alert you if there are any fire or water leaks. The HCS-3 also offers multiple advanced functions to control your entire grow room or greenhouse such as Sunrise / Sunset simulation, DLI control, overheat protection, Spectrum & Group lighting control, and more.

The MBS-PRO 4-in-1 sensor combines a precision air temperature, humidity, CO2 (PPM) sensor and photocell to create the perfect all-in-one environmental sensor. It is designed for Hydro-X Pro system only.  Assembled using a new water-resistant plastic injected enclosure, the MBS-PRO can be placed in multiple locations throughout the growing area to provide spot measurements from multiple sensors (Up to 50 sensors can be connected to the Hydro-X Pro) The sensors can then be used together (averaged) or separately in order to control a specific section of the grow area by assigning a sensor to a specific control device. The MBS-PRO features a built-in LCD display to show the current conditions of that sensor which provide the ease of onsite monitoring. It also features a new “push-lock” connection to make installation easy.Please Note: The MBS-Pro requires the SPH-1 for supplemental power. "Sensors should remain dry and clean to prevent premature failure. Do not spray foreign substances or allow water / condensate on the sensors"

Trolmaster  4RS-1 4 Outlet Expander Station
Trolmaster
Trolmaster 4RS-1 4 Outlet Expander Station $ 137.75 $ 145.00
The 4RS-1 is a universal 4-outlet power expansion module. It can be used with any of TrolMaster’s “plug-in” style device modules to expand the number of devices that can be controlled by the Hydro-x. A single 120-240 volt “trigger” cable on the 4RS-1 connects to your device / control module. When the device module is activated by the Hydro-x, the 4RS-1 trigger cable will turn on each of the 4 receptacles on the 4RS-1 with a 3 second time delay between each outlet being activated. That minimizes high start-up (inrush current) and allows up to 4 devices to be safely controlled. The 4RS-1 must be installed with a 120/240 volt power circuit (up to 50-amps @ 240vac). Three wire terminals inside the unit accept up to #6 AWG wire making connections to the power source easy.
