Traditional Greenhouses are not the answer

Re-purposed floral or produce greenhouses or the warehouses currently being retrofitted by licensed corporate growing corporations today are old, inefficient structures, not designed for year-round growing.

Many existing empty greenhouses in the real estate market, currently being purchased by licensed growers are available because they are in various states of disrepair. These often contain outdated and inefficient support systems, leaky or illfitting poly-carbonate/glass panels, and more. They typically have high costs for heating/cooling and humidifying over the growing season due to the extreme temperature shifts inside a greenhouse seasonally.

Day to day differences caused by full sunlight conditions, versus high-temperature cloud cover and humidity, can cost thousands in operating costs to keep plants safe and productive. This increases costs to producers over the year, between lack of air movement and deadly high heat temperatures inside in the peak of summer, too cold and incredibly high heating costs for these enormous, thin glass or plastic walled spaces in the winter.

All of these changes in conditions cause stress to the plants, inhibit successful plant growth, can trigger early flowering and lead to production losses from low quality and other plant problems.

In the case of medical marijuana specifications, growing large amounts of plants in various stages of growth in an open warehouse setting can cause cross-contamination and inconsistent terpene profiles, CBD and THC levels.

This open setting massive greenhouse growing model also allows for the possibility of insect or fungal introduction from the outside environment which could affect all of your plant inventory destroying months of work and time and costing you millions in operating capital and production/delivery losses.

GMH Agrotunnel technology gives the grower an airtight, controllable, non-stressed environment with complete temperature and humidity control, protected from other plant inventories, insect or fungal invaders, day to day or season to season sunlight, heat or cold variables. The area above and around the plants to light, heat and humidify is greatly reduced, lowering operations costs per plant while maximizing performance.

24-hour light cycle an innovative approach to growth

Our Agrotunnel systems can operate with tested protocols for lighting using EMS Lighting for 24 hours a day without the need for a “rest cycle” as found with typical HID or LED lighting. This revolutionary approach speeds up plant growth and boosts production/profitability. Flowering can be triggered by cycles of 12 hours on and 12 hours off, when it is appropriate.

GMH Agrotunnels provides a precision controlled environment with consistent operating costs and results from day to day and year to year.
