Cultivating Cannabis: The Journey from Seed to Harvest
Cannabis is emerging from the shadows of strict regulation, prompting the growth of a global market worth almost $25 billion today. This green rush has led to increased revenues throughout the entire cannabis supply chain—most notably in cannabis cultivation.
Such growth is rippling across industries such as energy and agriculture technology, with innovation allowing for greater scale.
Today’s infographic from Water Ways Technologies follows the journey of the cannabis plant, and explores cutting-edge technology that will fuel the future of cannabis cultivation.
Breaking Down the Cultivation Process
Cannabis is an annual plant, meaning it naturally goes through its entire life cycle in one year. However, this cycle is shortened to 3 months in commercial cultivation to improve productivity.
Plants can be grown from either a seed or a clone. The cloning method guarantees consistency, cost savings, and provides genetic stability from a disease-free source. All of these factors contribute to its popularity with commercial growers and the medical cannabis community.
Each stage requires different variables to ensure the highest standards are being met.
- 1: Creating a Mother Plant: 3 months, 4 times a year
Mother plants create an endless supply of clones, making this stage the most crucial. The mother plant starts as a seed, chosen for desirable qualities that the grower wants to replicate—like aroma, flavor, and yield.
- 2: Making a Clone: 7-10 days
Growers then take clippings from the chosen mother plant, and dip each one in water and fertilizer. They are then soaked in rooting fluid and placed in a plug (individual cell), before entering an incubator.
The clippings remain here until they finish rooting. The incubator maintains the plant’s moisture by facilitating leaf absorption.
- 3: Vegetation Process: 3-4 weeks
The clones are transferred to growing rooms and placed into a light substance similar to soil. They are moved on to flood benches—large tables that re-circulate excess water and fertilizer—which enable the optimal uptake of nutrients.
During this phase, the clones require 18 hours of light and 6 hours of darkness. There must be a constant analysis of the radiation levels to combat any damage from the artificial light source.
- 4: Flowering: 6-8 weeks
Following the vegetation process, the plants are separated into different flowering rooms. During this phase, buds grow and develop a solid cannabinoid and terpene profile. Terpenes are organic compounds that give cannabis varieties their distinctive aromas like citrus, berry, mint, and pine.
- 5: Post-harvest: 1-3 weeks
The cannabis plant is harvested once it reaches maturity. The flowers are de-budded, trimmed, and set on drying trays in a post-harvest room with low humidity, before they are ready for extraction.
This final stage requires a substantial amount of time and attention to detail, to ensure the best quality and most potent product possible.

Ranked: Emissions per Capita of the Top 30 U.S. Investor-Owned Utilities
Roughly 25% of all GHG emissions come from electricity production. See how the top 30 IOUs rank by emissions per capita.
Emissions per Capita of the Top 30 U.S. Investor-Owned Utilities
Approximately 25% of all U.S. greenhouse gas emissions (GHG) come from electricity generation.
Subsequently, this means investor-owned utilities (IOUs) will have a crucial role to play around carbon reduction initiatives. This is particularly true for the top 30 IOUs, where almost 75% of utility customers get their electricity from.
This infographic from the National Public Utilities Council ranks the largest IOUs by emissions per capita. By accounting for the varying customer bases they serve, we get a more accurate look at their green energy practices. Here’s how they line up.
Per Capita Rankings
The emissions per capita rankings for the top 30 investor-owned utilities have large disparities from one another.
Totals range from a high of 25.8 tons of CO2 per customer annually to a low of 0.5 tons.
|Utility||Emissions Per Capita (CO2 tons per year)||Total Emissions (M)|
|Berkshire Hathaway Energy||14.0||57.2|
|American Electric Power||9.2||50.9|
|Florida Power and Light||8.0||41.0|
|Portland General Electric||7.6||6.9|
|Pacific Gas and Electric||0.5||2.6|
|Next Era Energy Resources||0||1.1|
PNM Resources data is from 2019, all other data is as of 2020
Let’s start by looking at the higher scoring IOUs.
TransAlta emits 25.8 tons of CO2 emissions per customer, the largest of any utility on a per capita basis. Altogether, the company’s 630,000 customers emit 16.3 million metric tons. On a recent earnings call, its management discussed clear intent to phase out coal and grow their renewables mix by doubling their renewables fleet. And so far it appears they’ve been making good on their promise, having shut down the Canadian Highvale coal mine recently.
Vistra had the highest total emissions at 97 million tons of CO2 per year and is almost exclusively a coal and gas generator. However, the company announced plans for 60% reductions in CO2 emissions by 2030 and is striving to be carbon neutral by 2050. As the highest total emitter, this transition would make a noticeable impact on total utility emissions if successful.
Currently, based on their 4.3 million customers, Vistra sees per capita emissions of 22.4 tons a year. The utility is a key electricity provider for Texas, ad here’s how their electricity mix compares to that of the state as a whole:
|Energy Source||Vistra||State of Texas|
Despite their ambitious green energy pledges, for now only 1% of Vistra’s electricity comes from renewables compared to 24% for Texas, where wind energy is prospering.
Based on those scores, the average customer from some of the highest emitting utility groups emit about the same as a customer from each of the bottom seven, who clearly have greener energy practices. Let’s take a closer look at emissions for some of the bottom scoring entities.
Utilities With The Greenest Energy Practices
Groups with the lowest carbon emission scores are in many ways leaders on the path towards a greener future.
Exelon emits only 3.8 tons of CO2 emissions per capita annually and is one of the top clean power generators across the Americas. In the last decade they’ve reduced their GHG emissions by 18 million metric tons, and have recently teamed up with the state of Illinois through the Clean Energy Jobs Act. Through this, Exelon will receive $700 million in subsidies as it phases out coal and gas plants to meet 2030 and 2045 targets.
Consolidated Edison serves nearly 4 million customers with a large chunk coming from New York state. Altogether, they emit 1.6 tons of CO2 emissions per capita from their electricity generation.
The utility group is making notable strides towards a sustainable future by expanding its renewable projects and testing higher capacity limits. In addition, they are often praised for their financial management and carry the title of dividend aristocrat, having increased their dividend for 47 years and counting. In fact, this is the longest out of any utility company in the S&P 500.
A Sustainable Tomorrow
Altogether, utilities will have a pivotal role to play in decarbonization efforts. This is particularly true for the top 30 U.S. IOUs, who serve millions of Americans.
Ultimately, this means a unique moment for utilities is emerging. As the transition toward cleaner energy continues and various groups push to achieve their goals, all eyes will be on utilities to deliver.

The Road to Decarbonization: How Asphalt is Affecting the Planet
The U.S. alone generates ∼12 million tons of asphalt shingles tear-off waste and installation scrap every year and more than 90% of it is dumped into landfills.
The Road to Decarbonization: How Asphalt is Affecting the Planet
Asphalt, also known as bitumen, has various applications in the modern economy, with annual demand reaching 110 million tons globally.
Until the 20th century, natural asphalt made from decomposed plants accounted for the majority of asphalt production. Today, most asphalt is refined from crude oil.
This graphic, sponsored by Northstar Clean Technologies, shows how new technologies to reuse and recycle asphalt can help protect the environment.
The Impact of Climate Change
Pollution from vehicles is expected to decline as electric vehicles replace internal combustion engines.
But pollution from asphalt could actually increase in the next decades because of rising temperatures in some parts of the Earth. When subjected to extreme temperatures, asphalt releases harmful greenhouse gases (GHG) into the atmosphere.
|Emissions from Road Construction (Source)||CO2 equivalent (%)|
|Excavators and Haulers||16%|
Asphalt paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively. Furthermore, 75% of single-family detached homes in Canada and the U.S. have asphalt shingles on their roofs.
Reducing the Environmental Impact of Asphalt
Similar to roads, asphalt shingles have oil as the primary component, which is especially harmful to the environment.
Shingles do not decompose or biodegrade. The U.S. alone generates ∼12 million tons of asphalt shingles tear-off waste and installation scrap every year and more than 90% of it is dumped into landfills, the equivalent of 20 million barrels of oil.
But most of it can be reused, rather than taking up valuable landfill space.
Using technology, the primary components in shingles can be repurposed into liquid asphalt, aggregate, and fiber, for use in road construction, embankments, and new shingles.
Providing the construction industry with clean, sustainable processing solutions is also a big business opportunity. Canada alone is a $1.3 billion market for recovering and reprocessing shingles.
Northstar Clean Technologies is the only public company that repurposes 99% of asphalt shingles components that otherwise go to landfills.
