Brand: Grass Stitcher Model: GSD-002 Part Number: GSD-002
The Grass Stitcher lets you inexpensively repair bare spots in your lawn quickly and easily. This revolutionary eco-lawn tool works right through dead grass, and leaving the organic material in place adds beneficial mulch and nutrients. Just add seed and water and walk away. There are many ways to make holes in the ground, but no tool can make holes like the Grass Stitcher.

The efficient handle allows users to easily apply force to the wheels using either foot pressure or body weight. Durable poly/fiberglass wheels withstand the force so the spikes penetrate the soil at the correct depth. The wheels penetrate at a distinct angle, creating a plowing effect, loosening and mounding soil. The spikes penetrate up to their small, stubby support arm, achieving the correct depth each time and creating an extra-wide hole that's surrounded by the mounded loose soil. The loosened soil crumbles on top of the seeds when watered. The spiked wheels grind the existing grass, effectively recycling it as mulch. Just Stitch, Seed and Sprinkle. No bulky power machines. No Messy, ineffective patch materials. No wheel-barreling. Heavy topsoil. No need to remove dead lawn. No heavy sod. | *$149.99 |

 | Green Air CD-36NG: CO2 Generator w/ NG Rated Hoses- 36 cu. ft./h
Brand: Green Air Products
Carbon dioxide generators operate by burning carbonaceous fuels such as propane or natural gas. The burners used in Green Air Products CO2 generators are specially designed to maximize the production of CO2 and minimize heat as a by-product. Green Air Products generators provide CO2 far more economically than any other means of enrichment. A constant burning pilot is used to ignite the gas when the generator is turned on. A thermocouple is used to monitor the pilot flame. If the pilot flame is lost, a safety valve will close so that unburned fuel will not be released into the enclosure. CO2 Generator operations may be automatically functioned according to actual ambient values when installed in conjunction with the CDMC. The generators may be controlled with timers such as the Cyclestat 4P. This control device continually samples the level of carbon dioxide in the growing area and functions the generator whenever CO2 levels do not meet your predetermined values. Generators are easily installed, dependable and efficient. Transformer included. Operates on 110 VAC. | *$708.00 |

 | Green Air CDDS-2 and CDM-6000: Sensor
Brand: Green Air Products
These Green Air Products systems are a breakthrough in CO2 detection and control. The CDMC-6 system is designed to sample the air and learn the characteristic of your space, then make adjustments as necessary to ensure a constant level of CO2. The CDM-6000 monitor employs a passive infrared sensor which samples the air once every second and then sends the sample data to the CDDS-2 sequencer. The CDDS-2 then activates or deactivates your CO2 enrichment or venting (exhaust) equipment to maintain desired CO2 PPM. The CDDS-2 uses a sophisticated adaptive algorithm or "Overshoot Protection Logic " to learn the dynamics of the space being controlled. This allows the systems to avoid dramatic overshoots inherent to set point controllers or timed CO2 enrichment. These learned parameters are stored in the memory, even when the 'POWER ' is off, or until you reset the unit. The CDMC-6 system offers a large LCD screen displaying the current CO2 levels in PPM. Set your desired CO2 level, 'Hysteresis ' and 'Elevation ' to maintain precise levels without guesswork. The CDMC-6 system can be using for enriching or venting CO2 and incorporates a photosensor to defeat CO2 during dark periods (Night). | *$850.57 |
