Odor-Sok Air Filters are constructed using bundles of microscopic activated carbon filaments and fibres. By controlling fibre width to 20 nm, the absorption rate of carbon cloth is similar to that of a single exposed carbon particle. Air flows evenly across teh carbon and with accelerated absorption and increased surface area, Odor-Sok Air Filters retain all the properties of traditional canister filters. Faster absorption rates means smaller filter equipment and up to thirty times less carbon in use for the same result over a one-year period. That's how!

Finally, a safe and very efficient way to water-cool your entire grow room! It consists of a high-quality heat-exchanger with a strong molded plastic housing. One side of the housing is designed to install over a 6" air-cooled reflector duct flange, and as an option the opposite side can be attached to 6" air ducting (depending on inline fan placement). Air from your indoor garden is either pushed or pulled through the reflectors with an inline fan and then passed over the Ice Box heat exchanger. Cold water is circulated through the heat exchanger, cooling the air before it exits right back into the indoor garden area.

EVC-2 by Sentinel Sentinel has combined digital temperature & humidity controls together in one flexible unit called the EVC-2 / Environmental Controller. It has two additional features which activate a Night Device and a CO2 device. The EVC-2 provides the perfect combination of features

The EVC-2 controls your Temperature & Humidity with DIGITAL accuracy.

The EVC-1 Environmental Controller controls all that and more. If you want a simple-to-use and reliable controller without spending hundreds of $, check out the EVC-1.

The EVC-1 provides extreme flexibility in a reliable solid-state environmental controller. Selectable CO2 , Temperature and Humidity modes allow the user to control temperature & humidity separately or together. Built in photocell activates CO2 device during the day. Night device outlet can control an exhaust fan / sulfur burner etc.

Sentinel CO2 Generators Carbon Dioxide / CO2 is critical for all plants. Normal atmospheric air around the world averages about 380 PPM (Parts Per Million). When plants are provided higher levels of carbon dioxide, they can grow faster and larger. It is usually agreed by experts that 1500 PPM is beneficial to plants. Gas burning CO2 generators are the most effective way of producing CO2.

The VCG-27 and VCG-6 are the safest and most advanced CO2 generators available today

• Available in both Propane and Natural Gas

• Variable CO2 output from 3 to 6 cubic foot CO2 / Hr.

• Solid state electronic ignition control module eliminates the open pilot flame

• Tip-over switch shuts off the gas flow in the event the unit falls or tips over

• Unit comes standard with 2 brass burners pre-installed

• The burners are designed to burn clean and produce consistent blue flames

• Dual redundant low-voltage solenoid valves add a second layer of safety

• Comes complete with 12 foot hose and pressure regulator

VCG-6 Propane

Free shipping for the contiguous 48 states.

• Available in both Propane and Natural Gas

• Solid state electronic ignition control module eliminates the open pilot flame

• Tip-over switch shuts off the gas flow in the event the unit falls or tips over

• Unit comes standard with 10 brass burners pre-installed

• The burners are designed to burn clean and produce consistent blue flames

• Dual redundant low-voltage solenoid valves add a second layer of safety

• Comes complete with 12 foot hose and pressure regulator

The HydroGen is the world’s first and only water cooled CO2 generator. Water cooling is capable of removing 86% of the heat produced by burning propane and has loads of other options and features not available in any other CO2 generator on the market, including a completely adjustable flame (can produce anywhere between 15 and 45 cubic feet of CO2 per hr), an adjustable water flow valve, no pilot light (flame is activated by water flow), a tip over cut off, an overheat shut down sensor, and the list goes on. The unit can easily be used in a closed-loop system with a small chiller and reservoir, or you can connect directly to your home water supply and drain to storage for reuse in your garden. The unit is compact in size and can be either hung or wall-mounted anywhere in your garden.

This optional valve (used in place of a pump) is designed to be installed in a pressurized water line and to be controlled by your CO2 monitor. This is a high quality solid brass valve designed for years of service. The valve has 1/2” NPT outlets that can be used to attach the valve inline with your existing plumbing or you can install on ½” hose barbs to make the connection. You will need either a pump or a valve but not both. 1 Year Warranty.

Maintaining a CO2 level between 1000 and 1500 PPM is essential for most plants. CO2 can be increased by either using compressed CO2 or or a CO2 generator. How do you know if you have the necessary level? Eliminate the guesswork.

• One touch calibration of the CO2 sensor

• Simple pushbuttons to enter desired PPM settings and display the current CO2 PPM readings

• Easy to read LED display.

• Can be operated in "Fuzzy Logic" mode for compressed CO2 or On/Off for CO2 generators.

• Optional 12 volt DC adapter allows for coordination with other controllers like the EVC-2

• CO2 receptacle to connect CO2 generator or 120 volt compressed CO2 solenoid / regulator assembly

• The supplied 12 volt power supply connects to any temperature controller so that the CO2 devise will be disabled when the fan is operating

• Remote CO2 and light level sensor can be positioned inside the area and the CPPM-1 outside of the area

• Comes with 15 ft cable
