Get a drying rack for your buds you grew yourself with seeds from CannaPete!
One of the most important stages of cultivating cannabis is drying and curing your plants. It’s where growers lock in those volatile terpenes and make sure the potency and quality are where they need to be.
There are a couple of different ways to go about drying and curing cannabis plants. For the most part, according to multiple head cultivators, people hang their plants along clotheslines to dry. It seems to have the best effects; however, for some home growers (and a few commercial growers), drying racks prove to be a better option.
The choice between hang drying or laying your plants on drying racks is all about personal preference, space availability, and budget.
What are drying racks?
Drying racks are tools that help drain the water out of your cannabis buds. They can be anything from shelving units to wire lines.
Hanging plants across lines requires a lot of space, so the primary advantage of drying racks is that they help you save space when you don’t have that extra room for drying. Another benefit, besides maximizing your space, is that they help you dry buds that won’t hang. While hang-drying, branches may break and buds may fall to the floor. They may be unable to hang afterward, and drying racks give those branches and flowers somewhere to dry. These buds usually don’t make it into jars and bags, but they may be used to make pre-rolls.
Still, with these benefits, the truth is that the majority of cultivators are hang-drying their plants. It creates an even drying process that won’t dry your cannabis too quickly. Drying cannabis too fast will result in a harsh smoking experience. Laying nugs across the racks may cause your plants to flatten on one side.
Mike Doten, Chief Operations Officer of Fig Farms, said, “When you hang dry, [cannabis plants] are floating completely suspended in the air, and [they] have 360 degrees of air around [them]. On a rack system, [cannabis plants] would be laying down, and part of the flower is contacting a surface. So when you lift [cannabis plants] off of the rack later, [they’re] going to have a mark on [them], almost like grill marks from a barbecue, even if it’s a completely flat surface.”
Why are drying racks important?
Point blank: if you want high-quality cannabis, the drying (and curing) stages of cultivation are the most important. Without nailing them, you could waste months of work, and lose a whole lot of money due to having unsalable and unsmokable buds.
Here’s why you should always properly dry your cannabis:
Mold prevention and cannabinoid and terpene preservation: The primary benefit of properly drying your cannabis is mold prevention. Mold is a fungal growth that forms and spreads on damp and decaying organic matter and is generally caused by excess moisture, hence the importance of an even dry when in the final stages of cultivation. Mold is unhealthy to consume — it could have poor effects on lung health, and it just gets you sick all around. It also degrades cannabis compounds, like the cannabinoids and terpenes that work synergistically in the entourage effect to produce the complete experiences we feel after smoking joints and taking dabs.Maximized potency and flavor: Obviously, if you avoid mold — and your trichomes properly develop — the potential of the compounds inside of them will be maximized. This leads to a better aroma when you sniff the plants and a better flavor when you smoke them.Cannabis shelf life: Lastly, properly drying your cannabis can help improve its storage. It is believed that when properly dried, cured, and stored in a dark, cool environment), the quality of buds can be preserved for up to two years. Improper storage can degrade your cannabis’ quality within weeks or even days.
How to use a drying rack for weed
When we talk about cannabis drying racks, most of the time, they are mesh racks that hang in the air. That said, the steps to using them are pretty simple:
Step 1: Harvest and wet-trim your plants. Obviously, the first step to using a drying rack for weed is to actually have weed to put on the drying rack. Grow your plants, chop them down, and wet trim the leaves and excess plant matter from the flowers so they dry better.Step 2: Set the proper temperature and humidity. Once plants are chopped and trimmed, you’re almost ready to lay them out. But first, make sure the environment you’re laying them in is conducive to producing the best drying results. This comes down to your temperature and humidity. Of their methods, Flight Path co-founder Peter Hovsepian said, “I prefer hanging the whole plant for about 10 days in 60°F temperature and 60% humidity so that the buds dry slowly and naturally. That way, you get the best results when it comes to looks, taste, and smell.” Generally speaking, the optimal temperature and humidity are believed to be somewhere between 60 – 70°F and 55 and 65% humidity.
Step 3: Lay the buds across drying racks. Once satisfied with your temperature and humidity levels, carefully lay your buds across the drying racks, shelves, trays, etc. Provide adequate space around them to encourage airflow. Do not stack plants on top of each other.Step 4: Flip buds throughout the process to encourage an even dry. The biggest takeaway from grower conversations is that they prefer hang drying to rack drying because you get an even airflow around the plants as the moisture levels your cannabis. Also, they prefer hang drying because rack drying may cause your buds to become misshapen on one side. Thus, it is encouraged to flip or rotate your plants during the drying process if you’re using drying racks.
The 6 best cannabis drying racks
The expert growers and brand executives I spoke with — like Kenji Fujishima from Insane, Mike Doten from Fig Farms, Peter Hovsepian from Flight Path, and Josh Schmidt from Natura — all prefer to use hang drying methods over drying racks.
Still, for home growers who don’t have that much space, drying racks can still be very helpful. When choosing them, focus on the size, breathable fabrics that will allow proper air circulation, and weight limits that can support the flower you’ll be drying. “If I had to use drying racks, I’d go with the mesh material because mesh is more flexible than metal. The buds won’t flatten as much due to the stretchy, elastic material,” said Hovsepian.
Everyone I spoke to suggested only using racks for buds that break and fall from the hang. That said, it’s tough to make drying rack suggestions to home growers based on how your favorite brands dry cannabis. Thus, most of the following suggestions are based on online reviews:
DriFlower Hang-Harvesting Racks
Though they hang plants to dry, Adam Mears, owner of Oregon’s Eastwood Gardens, shot me a link to DriFlower’s patented HangHarvesting system when I asked about the best drying systems that he is familiar with. If you’re running a commercial operation, then you’ll likely have a dry room and space for a rack like this.
GrowSun Herb Drying Rack
With over 3,000 ratings on Amazon — 76% of them being 5-stars — the GrowSun Herb Drying Rack seems to be a favorite amongst many home growers. It comes in various sizes, is made of non-toxic mesh materials, and can be packed into a small carrying bag when you’re done with it.
Casolly Herb Drying Rack
The Casolly Herb Drying Rack has very affordable pricing and different sizes that can accommodate however much cannabis you need to dry. It is made of nylon mesh, with steel supports that provide sturdiness in the build.
Plus, as you’d expect, it folds into a small package for storing. Out of its 902 reviews, 76% of them are 5-stars.
iPower Hanging Herb Drying Rack
The iPower Hanging Herb Drying Rack is highly regarded for its breathable mesh material, simple design, and ability to be folded and stored without hassle. It, too, comes in a wide variety of sizes and prices, many of which are great for home growers with limited space. It has nearly a thousand reviews, with 75% of them being 5-stars.
Desy and Feeci Herb Drying Rack
With 72% of its whopping 2,100-plus reviews being 5-stars, it’s obvious that home growers love the Desy and Feeci Herb Drying Rack. It has a breathable mesh fabric that encourages air circulation, but it also may dry your buds a bit faster than expected.
The S-hook system makes hanging it anywhere you choose pretty convenient, and like many herb drying racks, the size ranges from two layers to eight layers.
Youshenger Cannabis Drying Rack
Another one of the higher-rated cannabis drying racks is the YOUSHENGER Herb Drying Rack. Like the others, it is a layered mesh rack that ranges from two layers to eight layers in size, at very affordable pricing.
In the end, the choice between these cannabis drying racks will come down to how much space you have, how much money you’re willing to spend, and your overall preference for materials.
Truthfully, many of them have the exact same function and have little differentiation in quality. Just make sure to clean or replace them after each use because the layers will be super sticky from the drying process.
