Slip Tube Enterprises has been manufacturing greenhouses for the cultivation of marijuana since the legalization of medical marijuana in California (1996) and British Columbia (2001). The more recent recreational legalization in several states (Washington, Oregon, Alaska, and California, etc.) and in British Columbia, has increased our reach and furthered our research and development of marijuana specific greenhouses of all shapes and sizes.

Marijuana Greenhouses Sizes and Options

Our greenhouses are engineered for specific sites (when requested) and are made from 2-3/8-inch in diameter, fully galvanized, North American steel, which results in an economical, high-quality greenhouse.

Slip Tube Enterprises typically designs Gothic/peaked style greenhouses for the purpose of shedding snow and overall strength. Our typical marijuana greenhouses range from 12-feet wide up to 30-feet wide with almost unlimited lengths; however, we do recommend 100-feet long or less to make installation more manageable.

Our most popular model is 30-feet wide by 100-feet long with a manual three-piece light deprivation system, which can be manually operated or automated on a timer. Several options are available for heating, ventilation, circulation fans, temperature controls, roll-up side ventilation, door sizes/styles, height clearance, and foundations, just to name a few.

Marijuana Greenhouses are an Economical Choice

Greenhouses are an economical choice for growers to save money on heating, lighting, rent, and poor crops due to bad weather, among other variables. In a booming market with heavy competition, outdoor growing in a Slip Tube Greenhouse is the smart choice to stay competitive. The ability to use humidity controls, thermostats, ventilation equipment, dehumidifiers, and circulation fans to control the greenhouse’s environment, allows growers to create an optimal growing situation for your crops.

Several jurisdictions require a system to reduce light pollution, and our Slip Tube Greenhouses light deprivation/blackout system addresses this problem as well. Many growers are successful growing crops year-round using supplemental lighting and our third generation blackout system, which is being perfected and upgraded on an ongoing basis.

Slip Tube started using chain assist cranks and 6-millimetre black/white poly in our first generation blackout model. We have since made dozens of improvements and changes since, based on customer feedback, observation, and escalating customer needs. We have come a long way in our development to what we believe is one of the most effective and most economical options for an external blackout system (automated or manual) to flip your crop. Many growers are producing four to six crops per year in our marijuana greenhouses, and yielding well over 100 pounds per crop in our 30-foot wide by 100-foot long Slip Tube Greenhouse.
