In the burgeoning cannabis market, grow facilities are facing more and more competition every day. New indoor cultivation enterprises are often being set up in formerly vacant industrial buildings and commercial spaces, while in other cases, companies are planning and constructing new grow facilities from the ground up. For all these establishments, continually lowering production costs while supplying the highest possible quality in ever-increasing yields is the way forward.
Whether in existing or new structures, concrete floors are ubiquitous throughout the majority of cannabis growing facilities. With the right treatment, these indoor concrete traffic surfaces can greatly contribute to a company achieving its operational objectives. Alternatively, insufficiently protected concrete floors can create annoying and costly barriers to accomplishing company goals.
Challenges in Cannabis Grow Facility Construction
As with any emergent industry, mainstream acceptance and market growth is bringing regulation to cannabis cultivation. Local governments are paying more attention to how cannabis growing facilities are constructed and operated. In addition to the standard business matters of building safety, employee working conditions and tax contributions, elected officials are increasingly under pressure from constituents to analyze the overall effect of grow facilities on their communities at large.
High consumption of energy for grow room lights and high water usage are just part of the equation. The temperature and humidity needs of a grow facility can be similar to that of an indoor swimming pool environment. While warmth and moisture are ideal for cannabis growth, they also provide the ideal conditions for the growth and proliferation of fungi and other undesirable microorganisms. Therefore, to help preserve plant health in the moist indoor climate, fumigation often comes into play.
Carbon dioxide (CO2) enrichment of grow room air, a common practice proven to increase crop yields, presents another set of safety and health considerations in dense urban environments.
Adding to these challenges, many cannabis grow facilities are producing plants destined for either pharmacological or nutritional use. This in itself demands scrutiny by regulators for the sake of the consuming public.
As a result, grow room managers and owners must stay informed about the evolution of the industry in terms of local and federal agency regulations concerning their facilities, their overall operation and their products.
Bare Concrete Floors in Grow Rooms
As a foundational construction material, concrete continues to lead the way in commercial and industrial construction. Despite the many advantages of concrete floors, when left unprotected they can present significant challenges specific to cannabis grow rooms.
- Untreated, bare concrete is naturally porous, easily absorbing liquids and environmental moisture. Substances found in grow rooms, such as fertilizers, fungicides and other chemicals, can leach through the porous concrete floor slab into the soil and ground water. Whether organic or synthetic, concentrations of such substances can be highly detrimental to the surrounding environment.
- Whether in an existing or newly constructed facility, it is not uncommon for the under-slab vapor barrier to be compromised during construction. When this occurs, moisture from the soil beneath the floor slab can enter the concrete and move osmotically upward, creating a phenomenon known as Moisture Vapor Transmission (MVT). The resulting moisture and moisture vapor tends to become ever more alkaline as it rises upward through the concrete slab. MVT can result in blistering, bubbles and other damage to floor coverings.
- The warm temperatures, regular watering of plants and high relative humidity maintained within many grow rooms can contribute to a weakening of the structural integrity of unprotected grow room slabs.
- Within the confined space of a grow room, the warm, moist air invites microbe proliferation. Food and pharmaceutical plants are high on the priority list when it comes to facility hygiene levels, as demanded by code.
Public health guidelines for cannabis cultivation facilities in various parts of the country are increasingly mirroring those of food processing. Typical requirements include having smooth, durable, non-absorbent floor surfaces that are easily cleaned and in good repair, possessing proper floor slope towards a sanitary floor drain, with no puddling, as well as an integral floor-to-wall cove base. These directives cannot be met with bare concrete alone.
Optimal Grow Room Flooring Performance
In some locations, cannabis growing facilities are already subject to strict building codes and regulations. This will no doubt be spreading to other regions in the near future. For example, the Public Health Agency of Los Angeles County publishes construction guidelines to ensure cannabis facility floors meet standards mirroring the food processing and pharmaceutical manufacturing industries, where sanitation, facility hygiene and safety are paramount. In these types of facilities, bare, unprotected concrete floor slabs are not allowed as a general rule, due to the material’s innate porosity and absorbency.
Flooring in grow rooms, like in their food and pharma industry counterparts, should optimally:
- Provide a monolithic and virtually seamless surface to help eliminate crevices, grout lines and other dark, damp locations where soil and pathogens tend to hide
- Be impervious and non-porous, providing a surface that can isolate toxic materials on the surface for proper clean-up where needed
- Enable correction or improvement of the floor slope for proper drainage, with no low spots to help avoid puddling
- Be installed with integral floor-to-wall cove options for easier wash-down and sanitizing
- Have the strength and thermal shock resistance, plus the tenacious bond, to undergo steam-cleaning and/or hot power washing, where needed
- Enable seamless, continuous surface installation over concrete curbs and containment areas
- Offer antimicrobial options for highly sensitive locations
- Demonstrate high compressive strength and impact resistance for durability under heavy loads
- Display excellent abrasion resistance, allowing the system to perform under grueling daily wear-and-tear
- Present customizable slip-resistance options that can be balanced with easy clean-ability
- Facilitate the use of floor safety markings, such as color-coded traffic and work area designations
- Be formulated with low odor, low-VOC chemistries that meet all EPA and similar regulations
- Be able to contribute LEED Green Building Credits, where desired
- Include options for refurbishing old or damaged concrete surfaces to allow reuse of existing facility resources, as opposed to having to be demolished, thus unnecessarily contributing to landfill waste
- Withstand and perform in continually damp grow room conditions, without degrading
- Be compliant with FDA, USDA, EPA, ADA, OSHA, as well as local regulations and/or guidelines
- Include MVT mitigating solutions where Moisture Vapor Transmission site issues are present
- Provide waterproofing underlayment options for multi-story facilities
- Demonstrate excellent resistance to a broad range of chemicals, fertilizers and extreme pH substances
Finding an affordable floor system with all the above features may seem like a tall order. Luckily, innovative manufacturers now offer cannabis facility flooring that meets sanitation, regulatory compliancy, durability and budgetary needs of growers.
Resinous Flooring Value for Cannabis Facilities
Choosing the right floor solutions for a given cultivation facility may be one of the most important decisions an owner or manager makes. Since floors are present throughout the structure, poor selection and compromised protection of concrete slabs can end up wreaking havoc with profits and yields over time.
Few facilities can afford the inconvenience and expense of an otherwise unnecessary floor repair or replacement. Having to suddenly move cumbersome plant beds and heavy pots in order to give workers access to the floor area can be headache. In addition, the unscheduled downtime and overall juggling of resources that invariably must take place make a strong case for investing in optimal grow room flooring from the start.
An excellent long-term value, professional-grade resinous floor systems present cannabis growers with a unique set of solutions for cultivation rooms. Not only does this type of flooring offer all the desirable features listed above, but also furnish a host of added benefits to grow room operations, including:
Very High Gloss Finish
- Highly reflective floor surfaces enable light entering the space from overhead to bounce back upward, exposing the underside of leaves to the light and potentially increasing yields
- Exceptionally high gloss floor finishes in light colors help make the most of your existing lighting sources, significantly increasing room illumination
- Achieving greater illumination without adding fixtures helps reduce energy consumption and associated costs
Virtually Seamless Surface
- Fluid-applied resin-based flooring provides an impermeable, monolithic surface that is exceptionally easy to clean and maintain
- The virtually seamless finish of resinous coated floors greatly reduces the number of locations for soil, pathogens and microbes to gather
- Resinous floors, by incorporating integral cove bases to eliminate ninety degree angles, correcting floor slope to eliminate puddling, and allowing for a virtually seamless surface, provide an optimally sanitary flooring solution
Outstanding Moisture Tolerance
- Designed specifically for use in wet industrial environments, cementitious urethane flooring is a top choice for humid grow rooms
- Also called “urethane mortar”, this type of floor can help mitigate certain undesirable site conditions, such as Moisture Vapor Transmission (MVT)
Chemical, Acid and Alkali Resistance
- Whether organic or synthetic, many soil enhancers and substances used to eradicate undesirable fungi and pests can damage concrete and shorten the usable life of foundational slabs
- Protecting concrete slabs with monolithic, non-absorbent and appropriately chemical resistant coating systems allows concrete to perform as designed, for as long as intended
- A proper barrier coating on the floor allows spilled or sprayed substances to be properly cleaned up and disposed of, rather than allowing the liquids to seep through the porous slab, and into the surrounding natural environment
- Resinous coating systems’ slip-resistance is completely customizable at the time of installation, enabling growers to request more traction in pedestrian walkways and less slip-resistance under raised beds.
- Epoxy, urethane and polyaspartic resinous flooring systems accommodate the installation of safety and line markings, as well as varying colors to delineate specific work areas
- The antimicrobial flooring options available from some manufacturers offer further hygiene support in highly sensitive facilities
- Today’s industrial resinous floor coatings from reputable suppliers are very low to zero V.O.C. and compliant with EPA and other environmental regulations
Resinous coating systems provide ideal value to informed growers who require durable, reliable and long-lasting high performance flooring for their facilities.
Support from the Ground Up
From incredible medical advances to high tensile fiber in construction materials, the expanding cannabis industry is bringing exciting opportunities to many areas of the economy. As more and more growers enter the market, so increases the pressure to compete.
By choosing light reflective, seamless and moisture tolerant resinous flooring that meets regulatory guidelines for grow rooms, managers can help reduce their overhead costs on multiple fronts — and get a jump on the competition.

1. What is CBD? What is CBD Oil?
Cannabidiol (CBD) is a naturally occurring constituent of industrial hemp/cannabis. Its formula is C21H30O2 and it has a molecular mass of 314.4636. It is the most abundant non-psychoactive cannabinoid found in cannabis, and is being scientifically investigated for various reasons.
CBD oil is a cannabis oil (whether derived from marijuana or industrial hemp, as the word cannabis is the latin genus name for both) that has significant amounts of cannabidiol (CBD) contained within it. Our CBD products and extracts are derived from industrial hemp, so they could be considered CBD-rich hemp oil, hemp derived CBD oil, CBD-rich cannabis oil, or plainly “hemp extracts” since they typically contain much more than just CBD. Again, cannabis doesn’t mean marijuana, but is the genus name, and general umbrella term which all forms of marijuana and hemp fall under. The form of cannabis we use for our CBD and hemp extracts is industrial hemp; we do not sell marijuana.
2. If a hemp extract is 40% cannabinoids, what’s the other 60%? What’s in your hemp extracts besides the naturally occurring cannabinoids?
Our Kentucky hemp extracts contain over 80 different phyto-cannabinoids such as cannabidiol (CBD), CBC, CBG, CBN, etc.. In addition to the cannabinoids naturally present in our agricultural hemp extracts, there are also many other types of natural molecules and phyto-chemical compounds such as amino acids, carbohydrates, vitamins (including B1, B2, B6, D), fatty acids (including omega 3 & 6), trace minerals (including iron, zinc, calcium, magnesium, potassium), beta-carotene, chlorophyll, flavanoids, ketones, nitrogenous compounds, alkanes, glycosides, pigments, water, and terpenes. The most common terpenes in our hemp extracts are Myrcene, Beta-caryophyllene, Terpinolene, Linalool, alpha-Pinene, beta-Pinene, Nerolidol og Phytol, trans-alpha-Bergamotene, Limonene/ beta-Phellandrene (Co-elution), and alpha-Humulene.
3. What’s the difference between Hemp and Marijuana?
Scientifically, industrial Hemp and Marijuana are the same plant, with a genus and species name of Cannabis Sativa. They have a drastically different genetic profile though. Industrial Hemp is always a strain of Cannabis sativa, while marijuana can be Cannabis sativa, Cannabis indica, or Cannabis ruderalis. The major difference is how industrial hemp has been bred compared to a marijuana form of Cannabis sativa. Typically speaking, industrial hemp is very fibrous, with long strong stalks, and barely has any flowering buds, while a marijuana strain of Cannabis sativa will be smaller, bushier, and full of flowering buds. However, newer industrial hemp varieties in the USA are being bred to have more flowers and higher yields of cannabinoids and terpenes, such as our Kentucky hemp we’re now using!
99% of the time marijuana has a high amount of THC and only a very low amount of CBD. Hemp, on the other hand, naturally has a very high amount of CBD in most instances, and only a trace amount of THC. Fortunately, the cannabinoid profile of hemp is ideal for people looking for benefits from cannabis without the ‘high.’ Hemp is used for making herbal supplements, food, fiber, rope, paper, bricks, oil, natural plastic, and so much more, whereas marijuana is usually used just recreationally, spiritually, and medicinally. The term cannabis oil can refer to either a marijuana or hemp derived oil, since marijuana and hemp are two different forms of cannabis.
In the USA the legal definition of “industrial hemp,” per Section 7606 of the Agricultural Appropriations Act of 2014, is “INDUSTRIAL HEMP — The term ‘‘industrial hemp’’ means the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis.”
4. Are hemp derived cannabinoids such as CBD as good as CBD from marijuana?
The short answer is yes. CBD is CBD, whether from marijuana or hemp. Most marijuana has a very low non-psychoactive cannabinoid profile (like CBD, CBC, CBG), so most of the time hemp would be much more preferable for anything besides THC. Marijuana is usually very high in THC (gives people the high) but usually very low in other non-psychoactive cannabinoids.
Nowadays in the USA, many farmers are growing industrial hemp flowers that are just as beautiful, odor-producing, and terpene rich as the best marijuana strains, such as our partnered farmers in Kentucky.
5. Why don’t you source your Hemp and CBD from within Colorado?
We feel that the hemp program in Kentucky is more well suited for our company in regards to growing hemp, and that because it’s 100% compliant with Section 7606 of the 2014 Farm Bill (and the 2016 Agricultural Appropriations Act), procuring it from there is perfectly legal at the federal level. Kentucky’s ecology is perfect for hemp just as it is for tobacco. The growing season is longer than in Colorado, and the soil is richer, so the quality of the hemp and the yields are better.
6. What’s the percentage of cannabinoids and CBD in your product?
Our raw extracts have varying percentages of cannabinoid and cannabidiol (CBD) content, the range being 10%-99%. Each product has a unique formulation and uses varying ratios of our extract types. Our CBD Isolate is over 99% pure CBD.
7. What is the best method of use?
For our dietary supplements we can only recommend them for internal consumption. Our CBD isolate is for research purposes only. If you don’t like the flavor of the oil supplements, you can mix with something sweet like apple sauce or honey to cut through the flavor.
8. What’s the ideal serving size for me, and how often should I take it?
There is no easy answer to this. Our starting recommended serving size is 15 drops but we generally recommend experimenting to see what feels best to you. Some prefer 5 drops, some prefer over 50 drops per day.
9. What is the safety of your hemp extracts? Are there negative side effects?
Hemp is considered by many to be generally safe. We’ve never seen or heard of any significant or negative side effects in our years in the industry. That said, we can’t rule them out. Please consult with your physician before using any dietary supplement including Hemp extract supplements.
10. Which of your CBD and hemp products should I get?
As a company who sells various dietary and food supplements, we can’t suggest any of our products for the prevention, treatment or cure of any disease or ailment.
When considering our different dietary hemp products, know that they all come in two strengths. Our Original Hemp blends (Classic Hemp Blend, Hemp Complete, Brainpower oil, & Signature Blend) all have 250+mg of cannabinoids per fluid ounce, and our concentrated blends have 1,500+mg per fluid ounce, six times the potency of our traditional oils. We’ve found that sometimes less is more, but nevertheless, some people like to take very large serving sizes of our hemp extracts.
The main difference between the four Original Blends is the additional herbal ingredients besides hemp. We suggest you research the separate components of each blend to determine which product may be most appealing to add to your dietary regimen. If you know it’s solely the hemp extract that you are looking for, with no additional ingredients, then Classic Hemp Blend or Classic Hemp 6x is what you’re looking for.
For dabbing and vaporizing or for research you can try our CBD Isolate.
THOSE WHO SUSPECT THEY MAY HAVE A DISEASE OR ARE SEEKING HELP FOR A DISEASE SHOULD CONSULT A QUALIFIED MEDICAL PROFESSIONAL.
11. Why do people use Hemp Extracts and CBD? What are the benefits and uses of CBD?
In accordance with federal regulations we cannot make health claims regarding our dietary supplement products. We can only recommend our products for general wellness.
12. Is a standard hemp seed oil the same as a high-CBD hemp extract?
Absolutely not. Standard hemp oil, which can be found very cheaply at a grocery store, is a much different product than our CO2 hemp extracts (not from seed). Standard hemp oil is produced by cold pressing the seeds, whereas our hemp extract is a supercritical CO2 extraction of the hemp plant itself, not the seeds. Hemp seed oil is considered to be a great nutritive food, but it doesn’t have the naturally occurring terpenes, cannabinoids and other components that our extracts do have.
13. Do I need to move to Colorado to get your Hemp Extracts and CBD? Where do you ship?
No. We actually source our hemp from Kentucky, as it’s legal to ship across state lines. Many people are under the impression that the only way to acquire hemp extracts and CBD for themselves or a loved one is to move to Colorado or another cannabis-friendly state. Many major news outlets are misinformed and are unfortunately spreading the idea that you can only get CBD oil in the states where medical marijuana has been legalized. This is simply not the case though. Because our extracts comes from hemp instead of marijuana, we can and do ship to all fifty states, and no medical marijuana card is needed. There are some exceptions, like with Indiana, Missouri and South Dakota we can’t sell our concentrated products due to state legislation.
We also ship to Japan, Australia, the EU, Switzerland, and Brazil. For all EU orders contact our exclusive distributor there, Cannawell.
14. Is your Hemp Extract Oil similar to Rick Simpson Hemp Oil?
Not quite. Ours are from hemp and RSHO is usually using marijuana, a different form of cannabis than industrial hemp. Our industrial hemp extracts are more standardized and will usually have a much higher content of non-psychoactive cannabinoids like CBD than one produced through the Rick Simpson method. And oils produced through his method will usually have a much higher THC content, as it’s typically marijuana that is used for RSHO.†
Generally speaking, most marijuana producers and sellers (especially on the black market) don’t test for contaminants (metals, pesticides, bacteria, etc.). Rick Simpson Hemp Oil is actually more a method of extraction than it is a specific product. People use the Rick Simpson method with hundreds of different strains of marijuana, so the THC, CBD and other cannabinoid content of the final oil is always varying greatly, depending on the cannabis the consumers are acquiring. Usually what’s used for Rick Simpson oil is a strain with an inferior CBD content (and high THC), because that’s what the vast amount of marijuana is nowadays.
15. Where do you source your hemp and CBD from?
We have partners in Kentucky who grew a dedicated plot for us this year (2016) which is being used in our products now. We also currently source from Europe but we’ll be changing that soon.
16. What kind of testing/analysis is performed on your products?
We have an industry leading quality control system, and we have third party laboratories analyze all of our hemp extracts and our final products for cannabinoid potency, heavy metals, bacterial and microbial life, mycotoxins (fungus), and pesticides.
17. What is CO2 extraction? What’s the difference between subcritical and supercritical CO2 extractions?
CO2 extraction is an extraction process that uses pressurized carbon dioxide to extract phyto-chemicals (such as CBD, CBG, or terpenes, flavonoids, etc.) from a plant. CO2 at certain temperatures and pressures acts like a solvent, without the dangers of actually being one. It is the most expensive extraction method, and is widely considered the most effective and safest plant extraction method in the world.
Many hemp and CBD companies boast about their supercritical CO2 extractions, but that’s actually only one (and perhaps an inferior) method of using a CO2 extraction machine. There are also subcritical CO2 extractions, and ‘mid-critical’, a general range between subcritical and supercritical. Subcritical (low temp, low pressure) CO2 extractions take more time and produce smaller yields than super-critical, but they retain the essential oils, terpenes, and other sensitive chemicals within the plant. Supercritical, on the other hand, is a high pressure and high temperature process that damages most terpenes and heat sensitive chemicals, but can extract much larger molecules such as lipids (omega 3 and 6), chlorophyll, and waxes. A truly full-spectrum CO2 extract includes first performing a subcritical extraction, separating the extracted oil, and then extracting the same plant material using supercritical pressure, and then homogenizing both oil extracts into one. In the essential oil industry, an extract made using this specific process is referred to as a CO2 Total.
18. What is the endocannabinoid system (ECS)?
“The endocannabinoid system (ECS) is a group of endogenous cannabinoid receptors located in the mammalian brain and throughout the central and peripheral nervous systems, consisting of neuromodulatory lipids and their receptors.” Wikipedia
There are two main types of receptors in the ECS, CB1 and CB2. CB1 receptors are primarily located in the central nervous system and brains of mammals, and CB2 are generally found in the peripheral nervous system. There are two main cannabinoids mammals produce- 2AG and Anandamide (named after the Sanskrit term “ananda” which translates to “peace”).
For hundreds of millions of years every vertebrate on Earth has been equipped with this ECS, a crucial system in the body, and it has been known about in the scientific and medical communities since the 1980’s. However, it’s still not taught about in most medical schools.
