North America’s Largest Cannabis Growers for 2021

As the cannabis industry continues its evolution, North America-based growing operations are scaling up across multiple states, and consolidation at the grower level — especially in Canada, where cannabis is already federally legal — remains robust.

Many of our 2021 Top Growers produce cannabis in a traditional greenhouse during some aspect of production, leveraging each production setting (outdoor, greenhouse, or warehouse growing) throughout the year.

According to the data, the largest North American grower producing cannabis exclusively in a greenhouse is Arizona’s Copperstate Farms at nearly 2 million square feet, while Glass House Farms in Santa Barbara, CA, is reportedly the largest cannabis greenhouse in the Golden State currently with two structures coming in at a combined 500,000 square feet.

Hello Mr Sparks.
So many discussions happening lately, yet it’s impossible at the moment to determine several factors.
There are various types of grow, especially what constitutes an indoor grow?
Inside a structure with artificial light only is one and
The indoor structures you mention in this article, such as a greenhouse utilizing Sunlight I believe should be labeled as it is, a Greenhouse. And should be labeled differently from indoor grow.
I’d love to hear feedback. Thank you for your time

Typically greenhouses thst use artificial supplemental light are designated “mix-light” operations. I have done extensive research and proformas on both mixed light and indoor operations and it’s almost easier to just build an indoor facility because the costs to build a mixed light facility as well as maintain interior temps can be as expensive as indoor facilities. Indoor will also get experienced growers 5 cycles per year whereas even the best mixed light ops like glasshouse still get 3-4. The heating bill to keep a greenhouse warm during the winter can be more expensive than the power bill for lights. Indoor will also demand higher shelf price, as most mixed light sungrown is capped on value.

Hello:
I am trying to communicate with multiple growers of cannabis who are looking to acquire a 100,000sf building in Bridgeport, CT. The city is welcoming a grower and asked me to try to contact interested companies. The property I represent has sole ownership of this property and is simply looking to sell it. The address is 50 Austin Street/275 Warren Street. It owns the entire block…1,45 acres and located at the junction of I-95 and Route 8. Please reply to my email address [email protected] or call me at 914.924.7889. I appreciate any information you can provide me with.
Thank you, Andy Grossman

I am a home grower in Australia. I’d love to visit you guys check out your operation, share some info. Were not far behind here in Aus legalisation is on the cards (sometimes it feels like one step forward, two steps backwards). I cannot wait to use my 20 years of experience, in a legitimate business operation. To turn my passion for growing into a business is my dream and my ultimate goal.
