Monitoring Systems for Outdoor Hemp Cultivation

With the increasing popularity of hemp cultivation outdoors and in greenhouses, new monitoring systems are entering the market to meet the needs of hemp farmers.

Hemp farming is fast becoming a popular industry due to its wide range of therapeutic and manufacturing uses. Many systems already exist for monitoring indoor hemp cultivation facilities, such as Urban-Gro and Braingrid, bringing novel, Internet of Things solutions into the hemp space.

Now that hemp is a fully legal agricultural commodity, more farmers are choosing to grow hemp outdoors. Within the CBD oil extraction industry, hemp is often found growing in a greenhouse. Both options are rising in popularity for hemp, meaning that monitoring systems for use in these environments are necessary.

Learn the requirements for effective monitoring systems, and take a look at some of the key players within the hemp cultivation industry.


A remote monitoring system is designed to safeguard against prolonged environmental conditions that could damage or destroy an entire crop. A remote monitoring system must be able to:

  • Track near real-time changes in ecological conditions.
  • Communicate alerts to the user independent of the Internet or an Ethernet cable (e.g., enabled via a secondary cellular network for redundancy)
  • Continue to operate in the event of a power outage (must have a battery backup system)

Depending upon the size of the operation, a monitoring system able to analyze different zones within the crop may be desired. If hemp is being grown in a greenhouse, choose a monitoring system that can also be connected to any HVAC or lighting equipment to monitor performance, and check for failures.


Monitoring systems are a core component of any automation system, as data must first be collected before an equipment or environmental decision can be made. Moving toward automation of the growing environment can accomplish the following:

Reduce the cost of labor

Automating essential tasks allows for less personnel, or grants staff to devote more of their time to other areas of interest, such as R&D or marketing efforts.

Increases yield and product quality

Measuring environmental conditions within a grow operation allows the farmer to improve their methods based on analyzed data and trends. This optimization often results in improved outcomes as related to quantity. Recipes for specific types of hemp can be created, ensuring repeatability in product quality.

Eliminate guesswork

Through analyzing cultivation data, the grower can make informed operational decisions. Changes in farming practices will only be based on evidence, rather than speculation. Sugarmade AI Cultivation Monitoring System

In May of this year, Sugarmade announced a new initiative to develop a simple, AI-based technology to monitor the cultivation of outdoor hemp. Sensors will be placed at appropriate locations throughout a hemp field and will gather data such as temperature, relative humidity, and soil moisture.

This monitoring system will be based on narrowband IoT technology, which is a type of cellular communications network. Advantages of this technology include a wider coverage area than other mobile networks and long battery life.

Sugarmade has not yet made public a timeline for the development of this technology.


Another cellular-based system, the Sensaphone remote monitoring devices are specifically designed for use in a greenhouse environment. Sensors are placed throughout the greenhouse, and temperature, ventilation, CO2, and relative humidity data is collected. The user can set threshold limits for each parameter and is notified via a call or text if any variable falls outside the threshold limits.

Alerts are also received in the event of a power outage or equipment failure. Data is backed up on the cloud for redundancy, and the device is equipped with an internal rechargeable battery for redundancy in the case of a power outage.


In addition to offering an automatic dosing system to ensure consistent fertigation, Link4 has also created a class of crop monitoring systems designed for greenhouse growing. These systems control as well as monitor, and can manage up to 24 HVAC and lighting devices.


A form of outdoor growing, protected cropping allows plants to grow in a fully outdoor environment but with the added benefit of minimal structures offering protection from the elements. Examples of such enclosures would be hoop houses, tunnel houses, and canopy protection.

Autogrow’s system allows the hemp farmer to monitor and control variables such as irrigation, fertigation, run-off, and root zone. The user receives an alert in the event of a problem and can manage the system remotely from their smart device.

Illinois Governor Signs Law Legalizing Recreational Use Of Marijuana

Illinois has become the 11th state in the country to legalize the recreational use and purchase of marijuana.

Democratic Gov. J.B. Pritzker, who was elected last year, signed the bill into law on Tuesday, fulfilling a key campaign promise. The state joins 10 others and the District of Columbia in allowing recreational use. The legislation takes effect on Jan. 1, 2020.

The new law allows Illinois residents who are 21 and older to possess up to 30 grams of cannabis flower, 5 grams of concentrate and 500 milligrams of THC in products such as edibles.

It also will expunge the records of 800,000 people with criminal records as a result of purchasing or possessing 30 grams or less of marijuana. It earmarks a quarter of the tax revenue from the sale of cannabis to redevelop impoverished communities in the state and gives vendor preference to minority owners.

BMW i8 Roadster: a Hybrid Roadster Review

BMW i8 Hybrid electric review by Fred Lambert:

The BMW i8 has been some kind of a black sheep in the German automaker ‘i’ brand. When BMW launched the i3, we thought that they would make ‘BMW i’ an all-electric brand, but they instead followed up with the BMW i8 as a plug-in hybrid.

It was disappointing, but to be fair to BMW, it is still the “most electric” roadster/coupé on the market years later and they give it an upgrade this year with a little more battery capacity and a convertible version.

So we decided to give it a shot. Here’s our review:BMW i8 Roadster Design

I’m told it’s a polarizing design. Some hate it and some love it.

I certainly fall under the second category.

The car looks stunning to me. I wasn’t completely on board with the original BMW i8 as I thought that it featured too many “electric design accents”, like the BMW i3, but I think they have smoothed some of those out over the last few small design updates and it’s much easier to get on board with the design.

BMW have also made some improvements specific to the i8 roadster version, which I think looks even better than the coupé.

BMW loaned us one in ‘e copper’ for our review and I don’t remember ever seeing a vehicle with that specific color. I don’t hate it.

Here’s our video review of the BMW i8 Roadster with some great shots by our videographer Scott Buscemi for you to get a good idea of the design:

BMW i8 Roadster Driving Experience

I had a ton of fun driving the BMW i8 Roadster. It’s a perfect car for a relaxing weekend drive or to have some fun on winding roads.

And speaking of winding roads, we took full advantage of the canyon roads around Malibu, where it was a blast to drive.

The car handles well and feels comfortable even with some aggressive steering, but it also feels a little underpowered for a sports car.

In my opinion, BMW wasn’t able to take advantage of the benefits of an electric powertrain – especially when it comes to the instant torque.

You can feel the lag of the gas engine when pressing on the accelerator for any kind of relatively aggressive acceleration. That’s understandable with only a 105 kW/143 hp electric motor and a small 3-cylinder engine, but it’s not what you’d expect from a car that looks like that.

Performance aside, it’s just great to pull the top down a drive around in the BMW i8 Roadster.

BMW i8 Roadster Range, Efficiency, and Charging

At 69 MPGe, the BMW i8 is certainly efficient for a sports car – but not very efficient for an electric car.

With the release of the new Roadster version, BMW updated the i8’s powertrain with a larger battery (11.6 kWh, up from 7 kWh).

It makes a decent difference.

At the launch, they were claiming a range of 33 miles (53 km) with this new battery pack, which feeds a 105 kW/143 hp electric motor driving the front wheels while a three-cylinder petrol engine with BMW TwinPower Turbo powers the rear wheels for an all-wheel-drive system.

The actual EPA range is only 17 miles and the system of the car that we tested was showing 22 miles on a full charge.

That’s not bad on paper.

Technically, many people could do their commute only on electric power, especially if they have a charger at work (the BMW i8 only has a 7 kW onboard charger but’s enough when you have a ~12 kWh battery pack). However, the problem is that the gas engine often kicks in during hard acceleration.

Therefore, it’s really hard to drive the BMW i8 on electric power only, unless you want to drive like your grandma.

Nonetheless, we are only talking about going into “electric assist” mode for short periods of time.

If you drive the car mostly in bursts of ~20 miles, which believe it or not is how most people drive on a day-to-day basis, and charge in between drives, you can potentially go months on a single tank of gas.

That said, I can’t help but to think: why not go all-electric?

BMW i8 Roadster Conclusion

And that’s the main takeaway I had from driving the BMW i8: make it all-electric. It would be a perfect car to be all-electric.

To be fair to BMW, it’s the most electric sports car you can buy right now. You have to give them that.

There are several EVs available today that have sports car performance, but they don’t really look like sports cars. The BMW i8 certainly looks the part.

Some are coming, but BMW has had the lead here for years.

My main problem here is that it seems that making the i8 all-electric would only make it better. The car was only showing a range of around 200 miles with a full tank of gas. EPA actually says a full range of 320 miles.

If range was the concern for them when deciding to make the i8 a plug-in hybrid, it makes no sense because you would have been able to get a longer range with something like an 80 kWh battery pack.

On top of the range, it would have supplied more power to the front electric motor and you could replace the gas engine with a second electric motor.

I don’t want to take anything away from the BMW engineers because it’s truly an impressive powertrain that they built, but look at how complex it is:

I can’t help but to think that it would have been better to make a more dual motor platform with a larger battery pack.

Cost shouldn’t be too much of an issue either. The vehicle starts at around $150,000 – with the Roadster version coming at a $15,000 premium.

I think that the price would be more justifiable if it came with an all-electric powertrain, which would undoubtedly result in higher performance.

There have been talks about BMW possibly killing the i3 and i8 programs ahead of their new generation of EVs.

I really don’t want them to kill the BMW i8. It’s too cool of a car for that. I just want them to make it all-electric.

All Electric Swedish Super Cars The New Formula 1

As reported on, Supercar maker Koenigsegg announced that it is taking a $170 million investment from NEVS, SAAB’s all-electric successor, and the company says that they will use the money to ramp up their electrification effort.

The two Swedish companies were already collaborating, but this latest move deepens their ties.

With a EUR 150 million (~$171 million USD) investment, NEVS is taking a 20 percent minority stake in Koenigsegg’s parent company and they are also setting up “a joint venture to expand into new market segments where NEVS AB is contributing USD 150 million in starting capital for a 65 percent stake and Koenigsegg obtains 35 percent by contributing primarily with intellectual property, technology licenses, and product design.”

Koenigsegg says that it will enable them to develop “parallel vehicle models in slightly higher volumes with emphasis on electrification.”

Christian von Koenigsegg, Founder and CEO of Koenigsegg, commented on the announcement:

“Koenigsegg is breaking new ground, capitalising on our unique technology, performance track record and market position to explore and develop new products. This partnership will create the best conditions for Koenigsegg to accelerate growth in the hyper car market, as well as enabling us to break ground into an untapped market segment together with NEVS. We very much look forward to working together with NEVS to develop products that ensure a sustainable future.”

The CEO of the world-famous supercar maker recently said that the new Tesla Roadster is ’embarrassing’ them and it is pushing them to look more into all-electric vehicles.

The company has previously incorporated hybrid electric powertrains into its vehicles, but they have yet to go all-electric.

Kai Johan Jiang, Chairman of the Board of Directors at NEVS AB, also commented on the new partnership:

“Koenigsegg is an enticing company developing advanced cars with unique technology and with a customer base that is one of a kind. To be able to expand our investment in the Swedish automotive industry through a company that we know and have an established relationship with, is an important step for us. We have both competencies and facilities to support Koenigsegg on their journey forward, something we look very much forward to”,

NEVS’ investment in Koenigsegg comes after they secured $2 billion in funding from China’s Evergrande Group, best known in the EV community for having taken a large stake in Faraday Future.
