Growing cannabis on a commercial scale can feel a bit like walking into uncharted territory. Sure, it’s exciting—you have a booming market, a product everyone’s talking about, and a big potential for success. But it’s not as simple as planting a seed, sitting back, and watching your cannabis empire grow. Cultivating high-quality cannabis comes with a unique set of challenges that can make even the most experienced grower have a rethink.
Every step of the process throws something new at you. And sometimes, it can feel like you’re playing a never-ending game of catch-up. But the beauty of it is that there’s always a solution if you know where to look.
That’s why, in this guide, we’ll talk about some of the most common obstacles in commercial cannabis cultivation and, more importantly, how to tackle them. Whether you’re just starting or you’ve been in the game for a while, we’re here to make the path a little easier.
Common Challenges and Practical Solutions to Overcome Them
Regulatory Compliance
– Problem
Regulatory compliance is one of the biggest headaches for anyone involved in commercial cannabis cultivation. You have to ensure that every aspect of your operation is in line with local, state, and even federal regulations—depending on where you’re growing. And these rules are constantly evolving, sometimes feeling like they change overnight.
This is such a challenge because cannabis is still somewhat of a legal gray area in many places. While some regions are fully on board, others are still figuring out how to regulate everything from the cultivation process to how the product is distributed. Therefore, failing to comply can result in hefty fines, losing your license, or even being shut down completely.
– Solution
- Stay Informed and Connected: Regulations change constantly, and waiting until you’re hit with a compliance audit is too late. Check your state or local cannabis laws regularly for updates.
- Hire a Compliance Officer or Consultant: If your operation is getting too big to handle all the legal stuff on your own, consider hiring a compliance officer or a specialized consultant. They’ll handle the heavy lifting regarding paperwork, filings, and navigating the more complex parts of the legal maze.
- Document Everything: Good record-keeping can save your skin in this business. Regulators love detailed documentation, so you should love it, too. This includes tracking every stage of your cultivation process—from seed to sale. Keep logs of plant health, pesticide use, harvest times, storage conditions, and anything else that could be relevant in an audit.
Pest and Disease Control
– Problem
Pest and disease control can feel like an ongoing battle in commercial cannabis cultivation. No matter how meticulously you plan, pests are always waiting in the wings, ready to wreak havoc on your crop. And when you’re cultivating thousands of plants, an outbreak can spread faster. Whether it’s spider mites, aphids, powdery mildew, or other common cannabis enemies, pests and diseases constantly threaten your plants and your harvest.
What makes this even trickier is the fact that cannabis is a highly regulated industry, meaning you can’t just douse your plants with any pesticide. Everything you use needs to be approved and compliant with local regulations. Plus, some chemical treatments can degrade the quality of your product, which is a big no when consumers expect top-tier cannabis.
So, how do you keep your plants safe without compromising quality or compliance?
– Solution
- Start with Prevention: A clean, growing environment is your first line of defense against pests and disease. Make sure your facility is spotless, with clean floors, equipment, and hands. Regularly sanitize your tools and growing surfaces to minimize the chances of contamination.
- Use Integrated Pest Management (IPM): IPM combines different practices to keep pest populations under control. It starts with monitoring your plants regularly to catch early signs of trouble, then introducing natural predators like ladybugs or predatory mites to deal with harmful pests. You can also rotate crops and adjust environmental factors like humidity and temperature to create conditions that pests hate.
- Choose Resistant Strains: When selecting your cannabis strains, look for ones that are naturally resistant to pests and diseases. Some strains are harder than others and can more easily fend off problems like mold or mildew.
- Use Organic Pest Control Methods: Using organic pest control methods is better for the environment and for business. Natural solutions like neem oil, diatomaceous earth, or insecticidal soap can be effective without compromising the quality of your plants.
- Quarantine New Plants: Anytime you introduce new plants, whether clones or seeds, quarantine them for a few weeks. This gives you time to monitor them for any signs of pests or diseases before they can spread to the rest of your crop.
Nutrient Management
– Problem
Nutrient management is like trying to find the perfect balance in a recipe. Too much or too little of any one ingredient, and the whole thing can go sideways. For cannabis plants, getting the right mix of nutrients is essential to healthy growth, potent yields, and overall plant quality. But cannabis is a picky plant, and what works for one strain or growing environment might be wrong for another.
A big challenge with nutrient management is that it’s not always easy to see what’s going wrong until it’s too late. On top of that, overfeeding can cause nutrient burn, while underfeeding leads to stunted growth, both of which can spell disaster in large-scale operations where time is money.
– Solution
- Test Your Soil (or Growing Medium) Regularly: You don’t want to start adding nutrients to your plants without knowing what’s already in the soil. Regular soil or growing medium tests can give you a clear picture of what your plants are working with. These tests measure the levels of important nutrients like nitrogen, phosphorus, and potassium and trace minerals like magnesium and calcium.
- Follow a Feeding Schedule: Most nutrient suppliers provide detailed feeding charts for cannabis, which break down what to give your plants during different stages of growth. Stick to the recommended guidelines, but remember that these are just starting points. Pay close attention to how your plants respond and adjust the schedule as needed.
- Monitor pH Levels: Your plants can only absorb nutrients if the pH of your growing medium is within the proper range. If the pH is too high or too low, even if you provide the perfect mix of nutrients, your plants won’t be able to take them up properly.
- Flush Your Plants Periodically: Sometimes, nutrients can build up in the growing medium, leading to a condition called nutrient lockout, where the plants can’t absorb any more nutrients, no matter how much you feed them. To prevent this, do a “flush” every now and then, particularly before harvest. Flushing involves watering your plants with pH-balanced water only (no nutrients) for a short period to wash out any excess salts or nutrients in the soil. This helps reset the growing medium and ensures that your plants are getting exactly what they need.
Climate Control and Environmental Factors
– Problem
Cannabis plants are sensitive to temperature, humidity, light, and airflow. When any of these elements are off, your plants can struggle to grow, get stressed, or even become more susceptible to pests and diseases. And in a large-scale operation, where hundreds or even thousands of plants are involved, that can quickly spiral into a major issue.
Controlling the climate inside a grow room or greenhouse is especially tough because cannabis goes through different stages of growth, each with its own specific needs. Too much heat can dry out your plants, too little humidity can stunt growth, and insufficient light can reduce bud production.
– Solution
- Temperature Regulation: The ideal temperature range is usually between 76-80°F (24-27°C) during the day and a slightly cooler 65-68°F (18-20°C) at night. Invest in a reliable heating and cooling system. HVAC systems help keep indoor grows in a temperature range. You might need to rely on fans, shade systems, and heaters in greenhouses to keep things consistent.
- Humidity Control: A dehumidifier is your best friend when managing humidity. Industrial-sized dehumidifiers can be installed in larger operations to keep moisture levels in check. But if you’re growing in an especially dry area, a humidifier might be necessary during the vegetative stage.
- Airflow and Ventilation: Set up a solid ventilation system to keep the air flowing. Depending on the size of your operation, this could mean exhaust fans or inline fans. The goal is to ensure your plants get plenty of fresh air while old, stale air gets pushed out.
Labor Management and Training
– Problem
Managing labor and providing proper training are often overlooked, but they are major challenges in commercial cannabis cultivation. Having a well-trained and reliable workforce is just as important as the quality of your strains or your growing environment. Whether it’s trimming, watering, monitoring plant health, or handling post-harvest processes, each step requires precision, and mistakes can be costly.
But it’s not just about hiring people; it’s about hiring the right people and ensuring they have the skills to do the job well. Plus, the cannabis industry is unique in that it demands a balance of agricultural knowledge and compliance with strict regulations, meaning your team needs to be aware of both plant science and legal procedures.
– Solution
- Hire for the Right Skill Set: When hiring, look for people with both the right attitude and an eagerness to learn. Agricultural experience is great, but a candidate’s willingness to adapt and grow with the industry is even more important. You might need to put more effort into training them on cannabis-specific tasks, but if they’re motivated and dependable, that investment will pay off.
- Standardize Training Procedures: Create standardized training procedures for all aspects of your cultivation process. Each team member should follow the same protocols from pruning to nutrient management, pest control, or harvesting. Document these procedures clearly and provide ongoing training to ensure your team is up to date on new techniques and regulatory changes.
- Invest in Cross-Training: Cross-train your employees so they’re skilled in multiple areas of the cultivation process. This doesn’t mean everyone needs to be an expert in every task, but having a basic understanding of different roles can prevent delays. When employees can step into different roles as needed, you can create a more adaptable workforce.
Water Management
– Problem
Too much water can drown your plants, cause root rot, or cause good nutrients to just wash away. Too little water, on the other hand, can cause your plants to wilt, become stressed, and slow down in growth, not to mention how it can weaken their defenses against diseases and pests.
But it’s not just about how much water you give either; the quality of the water matters, too. Cannabis plants can be sensitive to contaminants, pH imbalances, and improper nutrient mixes. So, managing water correctly is a delicate dance.
– Solution
- Establish a Proper Watering Schedule: One of the biggest mistakes growers make is overwatering or underwatering, and cannabis plants are pretty particular about their hydration needs at different stages of growth. Set up a structured watering schedule that matches your plants’ specific life cycle. For young seedlings, light watering every couple of days works best, whereas mature plants need more water but less frequently.
- Implement an Efficient Irrigation System: For large-scale commercial cannabis cultivation, you’ll need to implement an irrigation system that can deliver water efficiently and evenly across your entire space. Drip irrigation is one of the best systems for cannabis cultivation. It delivers water directly to the root zone in controlled amounts, reducing water waste and preventing the over-saturation of soil. You can also use a timer to control when and how much water is delivered, so you’re not stuck watching the clock. In larger greenhouses, you can use sensors to monitor soil moisture and automate the irrigation system.
- Ensure Proper Drainage: Use pots or grow bags with suitable drainage holes, and add a layer of perlite or gravel at the bottom to help excess water escape. For soil growers, make sure your growing medium isn’t too compacted. If you’re in a hydroponic setup, monitor your water flow rates and ensure your drain system is working properly to avoid standing water.
Harvesting and Post-Harvest Handling
– Problem
Harvesting and post-harvest handling are like the grand finale of your commercial cannabis cultivation. After all the hard work of nurturing plants through their growth stages, the moment of truth arrives. How well you handle this final phase can significantly impact the quality and yield of your crop.
Some of the major challenges of these stages include:
- Timing the Harvest: One of the trickiest parts of cannabis cultivation is knowing the perfect time to harvest. If you wait too long, you risk losing potency as cannabinoids degrade. But if you harvest too early, you may not get the full flavor or effects.
- Intensive Manual Labor: Harvesting cannabis is labor-intensive and can be physically demanding. Depending on the size of your operation, you might find yourself and your team overwhelmed by the sheer amount of work to be done.
- Proper Techniques: Using improper harvesting techniques can lead to damaged buds, which in turn affects the quality of your product. Trimming, for example, requires a delicate touch; if you use too much force, you can crush the buds and release terpenes that contribute to flavor and aroma.
- Post-Harvest Storage and Drying: Once you harvest your plants, the drying and curing process begins. This stage is important for preserving the cannabinoids and terpenes.
– Solution
- Efficient Harvesting Tools: Use sharp scissors or specialized trimming shears designed for cannabis. They can make the process smoother and less damaging to the buds. Electric trimmers can also speed things up if you have a larger operation, but be cautious, as they can be harsher on the buds.
- Create a Harvesting Plan: Organize your team and create a detailed harvesting plan. You can assign specific tasks to different members to streamline the process and reduce stress. This can also help prevent them from feeling overwhelmed, allowing everyone to focus on their individual roles.
- Implement Quality Control Checks: Set up a quality control system to regularly check for mold or pests throughout the drying and curing processes. This might require you to visually inspect and sample the buds to ensure they meet your quality standards.
Managing Production Costs and Increasing Profits
– Problem
Many growers quickly discover that turning that green thumb into a profitable venture can be a bit more complicated. Setting up a cannabis cultivation facility can require lots of capital. From getting licenses and securing land to investing in advanced growing technology, the initial costs can be scary.
Then, once you’re up and running, the ongoing costs can pile up. This includes utilities, labor, equipment maintenance, and raw materials. If you don’t carefully manage them, these costs can quickly eat into your profits.
– Solution
- Have a Detailed Business Plan: Before diving in, take the time to create a comprehensive business plan. This plan should outline your projected costs, expected revenue, and a clear strategy for how you’ll manage both. This will help you make more informed decisions as you grow.
- Optimize the Use of Resources: Take a close look at how you use resources like water, nutrients, and energy. You can install technologies such as LED lights to reduce energy costs, while efficient irrigation systems can save water. The more efficiently you use resources, the lower your costs will be.
- Optimize Labor: Labor costs can quickly get out of hand, especially if your team is stretched thin. One way to manage this is to invest in automation where possible. You can also use automated irrigation systems to ensure your plants are watered consistently without needing someone to manually tend to them daily.
- Streamline Your Supply Chain: Take a good look at your supply chain. Are there opportunities to buy in bulk and save money? Could you work with a more affordable supplier? Even small reductions in the cost of nutrients, soil, or packaging materials can add up over time and save you a lot of money.
