Cultivation of Cannabis in a Greenhouse is also proven the way to go and is preferably for farmers and even many of the law enforcement officials across the country and in Northern California as well. These structures are lockable and can be controlled to eliminate odors.


While most greenhouse grows are in rural areas an on agricultural land, greenhouses are also suitable for urban settings- as they can be seen as compliant- if the grower can assure authorities that the structure can be secured have virtually little negative footprint You can also control the smell by using carbon exhaust filters and utilizing light proof covers to eliminate light pollution. Where it is currently allowed (or not)- more and more people are growing pot. Personal use is the main reason with commercial production close behind- with CBD varieties grown for commercial medicinal use showing great signs of promise. Bottom line is that virtually all the growers I meet tell me that just really enjoy growing the herb.

Large, commercial Greenhouses which can pass OSHA REGULATIONS coming in 2018 are the way that most forward-thinking Growers are going.AGRICULTURALGREENHOUSES

These greenhouses are usually not the traditional wood & glass greenhouse as they are considered "temporary farm structures" which can greatly aid agriculture operations. The USDA now encourages and even funds hightunnels for farmers growing conventional crops as these systems conserve water, power, and serve as a habitat for biological alternatives for pest control (such as ladybugs and lacewings) instead of chemical pesticides. These hightunnel systems may utilize natural ventilation and passive solar principals to enhance production and do not rely on electricity or heating fuels. Although more and more growers are using High Tech Hybrid technology that merges advanced digital electronic systems AND natural elements to produce High Quality Crops. Both High Tech and Low Tech Greenhouses (hightunnels) allow cultivators to limit production costs and benefit the environment by cutting down the carbon footprint of growing operations. Because of this, greenhouses have taken hold in both the conventional crop and cannabis industry. As cultivation expert Jorge Cervantes put it, "...a greenhouse is one of the best places to grow medicinal marijuana." Cannabis growers see the same advantages of being able to control the environmental conditions of their plants as well as having an alternative to chemical farming- add to this the added necessity of physical security and biological isolation and these systems are the wave of the future in crop production. Across the country more and more square footage is utilized for growing non-psychoactive cannabis for medicine (High CBD) varieties and more recently, for recreational (THC) use, where it is allowed. Medicinal growers find with a greenhouse, they can eliminate cross pollination isolate the mostly CBD strains that have been medically proven to alleviate pain, nausea, seizures; spasticity, epilepsy and neuropathic pain. It seems likely that it is just a matter of time before limited personal grows of THC types in a secure structure as well as large-scale commercial (and TAXABLE) grows of the CBD types will be allowed. Being able to lock the doors and keep those who should not have access to cannabis (primarily children and pets) is another reason for growing in a greenhouse, as these structures can be hardened to control access. Several nearby county officials have expressed to their growing communities that they would prefer all grows be indoor (greenhouse) and even some counties with the most restrictive 'rules' still license secure greenhouse grows.

The legislation requires the regulatory agencies to limit the number of Type 3 (Medium Cultivation) and Type 7 (Manufacturer 2 - Volatile Solvents). The legislation does not specify whether there will be limits on the the number of licenses issued for other license types.


Regulations limiting or authorizing vertical integration are an important feature of any regulated cannabis marketplace. In California, the Blue Ribbon Commission "and many of the individuals it consulted had significant reservations about the other end of the continuum, namely a market dominated by large corporations that could exert increasing influence on the commercial and political process." The Commission determined that "it is appropriate and probably wise for the state of California to adopt a path that limits the size and power—both economic and political—of any one entity in the marijuana industry." Further, the report went on to say that "In addition to limiting the scale of operations, it may be appropriate for the state to set limits on vertical integration."


The legislature took a decidedly cautious approach on vertical integration. A licensee may only hold a state license in up to two separate license categories, as follows:

Type 1, 1A, 1B, 2, 2A, or 2B licensees may also hold either a Type 6 or 7 state license.

Type 6 or 7 licensees, or a combination thereof, may also hold either a

Type 1, 1A, 1B, 2, 2A, or 2B state license.

Type 6 or 7 licensees, or a combination thereof, may also hold a Type 10A state license.

Type 10A licensees may also hold either a Type 6 or 7 state license, or a combination thereof.

Type 1, 1A, 1B, 2, 2A, or 2B licensees, or a combination thereof, may also hold a Type 10A state license.

Type 10A licensees may apply for Type 1, 1A, 1B, 2, 2A, or 2B state license, or a combination thereof.

Type 11 licensees shall apply for a Type 12 state license, but shall not apply for any other type of state licenses.

A Type 10A licensee may apply for a Type 6 or 7 state license and hold a 1, 1A, 1B, 2, 2A, 2B, 3, 3A, 3B, 4 or combination thereof if, under the 1, 1A, 1B, 2, 2A, 2B, 3, 3A, 3B, 4 or combination of licenses thereof, no more than four acres of total canopy size of cultivation by the licensee is occurring throughout the state during the period that the respective licenses are valid.

All cultivation pursuant to this section shall comply with local ordinances.

This paragraph shall become inoperative on January 1, 2026.
