One of the many reasons marijuana is illegal in Florida is that there’s no way to grow it without unleashing a host of environmental and social problems. A University of Florida study, published in PNAS, found a solution: hemp cultivation using indoor LED lighting could be an alternative crop if legalized.

The “cbd laws in florida 2020” is a study that has been published by the University of Florida. The study found that hemp cultivation would not be possible without legal and environmental risks.



The Institute of Food and Agricultural Sciences at the University of Florida has completed a two-year pilot project to assess hemp growing potential in the state. 

The goal of the research was to analyze hemp appropriateness in Florida, create management methods, and estimate the invasion danger. In both outdoor and greenhouse growth settings, the institution examined 50 distinct hemp types.

According to Zachary Brym, an agronomy assistant professor at UF and the hemp pilot project’s chief scientist, the researchers have yet to find a type that would thrive in Florida’s climate. 

Hemp growing in Florida is hampered by hot and humid weather, summer rainfall, and the length of days. 

“We don’t have a suggestion or any knowledge about a particular one (that might thrive), but we did identify many candidates,” Brym said. “We were able to kind of pinpoint a whole bunch of challenges,” she says.

Invasion danger

Some of these problems can be addressed by growing hemp inside in greenhouses, which also helps to solve possible invasiveness issues. 

Hemp produces a large number of tiny seeds that may be spread by birds, wind, or other environmental factors. If hemp fields aren’t properly cared to, the plant has the potential to spread to undesirable locations. 

Hemp is a “classic example of a potentially invasive species,” according to Brym. “It still has a lot of wild-type characteristics… We’ve seen hemp escape cultivation in several of our controlled trials, so the danger of invasion is still something to be concerned about.”

Hemp also presents certain environmental risks since growing requires fertilizer. Algal blooms and nitrogen pollution are fueled by fertilizer, which may lead to red tide in local rivers. 

The pilot program’s research doesn’t have all the answers on hemp fertilizer’s environmental effects, but Brym says that’s something he’s especially interested in as the program grows.

Researchers will investigate how much fertilizer each acre of hemp will need, as well as the quantity that will cause the least amount of harm while yet producing the finest hemp product. 

“We’re urging everyone to be aware of what they’re applying and to be conservative with it so that we don’t get into that situation where we’re applying too much and negatively affecting the environment,” Brym added. 

According to the U.S. Department of Agriculture, hemp must stay under a 0.3% THC threshold.

Limitations imposed by law

Farmers who wish to cultivate hemp should be aware of the legal implications.

Hemp must have less than 0.3 percent THC, according to the US Department of Agriculture. Plants that grow to be more than that must be killed. The problem is that a farmer has no means of knowing if a particular lot will exceed the THC limit. As a result, cultivating hemp is a high-risk endeavor.

Brym admits that some of the university’s tests went above the regulatory guidelines. 

“You may have all the ingredients for a very robust hemp harvest out in the field, but when you send it in for testing, it surpasses that 0.3 percent,” Brym said. “Then you come out of the field with nothing except a lot of heartache.”

For the time being, Brym does not believe that Florida hemp farming will bring in the sort of money that many people expect. 

Brym said, “Right now, there are greater economic challenges.” “It’s expensive to purchase the seeds and plant material, and there’s a lot of work, so anybody interested in growing hemp for profit should think about those kinds of things.” 

The “uf hemp” is a study that was conducted by the University of Florida. The study found that there are legal and environmental risks to cultivating hemp in Florida.
