Cannabis Nursery Room Design

The nursery is where it all begins. Just like the name implies, baby plants are nursed  in to teenage plants so they can be moved to the vegetative rooms. The way you start a plant is up to you - from seeds or clones - but whatever method you choose, the ultimate goal of the nursery room is to grow baby plants quickly without damaging them.

The nursery is where it all begins. Just like the name implies, baby plants are nursed  in to teenage plants so they can be moved to the vegetative rooms. The way you start a plant is up to you – from seeds or clones – but whatever method you choose, the ultimate goal of the nursery room is to grow baby plants quickly without damaging them.

Nursery Set-Up

To start a nursery room, you will need a way to store and grow the plants. We strongly recommend using metal shelving, clone trays, organic mats, and humidity domes lit with a small amount of LED or fluorescent lighting.

When designing the space, use standard 4’ wide x 18” deep stainless steel shelving. (This shelving can be purchased almost anywhere; they are sometimes called “baker’s racks.”) Also buy a 4’ fluorescent  or LED light strip for the fledgling plants. Setting up the shelves 18” apart (height) will give you enough space to put 2 trays per shelf. Each tray will comfortably hold 50 cuttings or seeds. More plants per tray is not recommended because plants need some space to grow.

With this setup, each shelving unit has the potential to hold up to 800 plants. It is recommended to have twice the amount of nursery plants/cuttings than the overall facility needs to keep vegetative rooms full. This allows you to choose only the healthiest and heartiest plants to move into the vegetative rooms.

Starting Cannabis Plants

There are many ways to grow plants from seeds or clones into mature plants ready for the vegetative rooms, including: clone machines, tissue culture, organic and rockwool plugs, and organic mats with a humidity dome and temp controlled root zone heat mat. Our current favorite is root mats as they are the simplest method and have a high success rate (up to 80%) with little effort. Using humidity domes as well protects the plants and removes worry about improper humidity levels in the nursery room, allowing you to focus more energy on vegetative and flower rooms.

When using humidity domes, at least one vent should be open at all times on the humidity to avoid building up too much humidity. If clones are rooted in extremely high humidity they will need to be hardened off in order to remove the domes without severe wilt.

It is important to note that baby plants should never be sprayed while in the humidity dome. This causes rotting of the plant material wherever water drops sit for extended periods of time without being able to dry.

Typically, baby plants are ready to leave the nursery two to three weeks after they are transplanted into rooting mats. Plants may look bad the first few days after being transferred out of the nursery due to the lower humidity levels; however, they will soon recover and be stronger because of the added strain.

Never coddle your baby plants. Start with more plants that you will ultimately need and be aggressive with them. Throw out any weak baby plants. If you are really good, you may even end up choosing the best of the best, and throwing out a few good plants simply because they are not as good as the others – only keep the best. This will create stronger mature plants, capable of producing a larger yield.

Space Constraints

Though recommended, the nursery does not need to actually be located in its own room. As a rule of thumb, three to five percent of the cultivation facility grow space should be dedicated to the nursery. In smaller cultivation centers, the nursery can be located inside a vegetative room as long as there is adequate space between the nursery shelving units and the lighting used for vegetative plants. Typically, eight feet is enough to separate nursery plants from vegetative plant lights; any closer and the more intense light used in vegetative rooms can stress and kill nursery plants.

Engineering Greatness: Meet Kenneth Loshelder, PE

Surna is extremely thankful for Kenneth and all that his team of engineers do for our company and for our clients. With over 15-years of experience, he has built a career focused on environmental consistency and energy efficiency. He encourages cultivators to engage with experienced mechanical engineers early-on in the buildout process. We asked Kenneth to answer some questions and lend valuable insight into the construction of cultivation facilities.

HVACD MEP Coordination for Cannabis Cultivation

Effective HVACD coordination is a key component in minimizing frustrating and costly construction delays in cannabis facility buildouts. There are a number of considerations your MEP team address in all stages of the project, from pre-design planning, to commissioning and beyond, in order to provide a comprehensive HVACD coordination effort.

What Causes Construction Delays for Cannabis Facilities?

Construction delays can be costly and frustrating. While it is impossible to see into the future and prevent everything that could conceivably go wrong when building out such a complex project such as a cannabis cultivation facility, there are several steps cultivators can take to minimize the risk of project delays and stay on schedule.

Grow Room HVACD Maintenance Plans: Getting the Most Out of Your Investment

Without a proper HVACD system maintenance plan, your energy bill will increase, your equipment could fail, and your plants will suffer. Avoid these problems and keep your climate system in working order with the help of this guide.

5 Reasons Why Your HVACD System Isn’t Performing

Our recognition in the industry as the experts in cultivation climates means that we are often asked to diagnose performance failures in systems not of our design. When we audit these systems, we find there are common themes as to why they aren’t performing as expected. Let's discuss the most common reasons we find for issues with HVACD system performance.

Hot Weather Growing – Cannabis Cultivation in Extreme Climates

There are so many options for climate control in cultivation facilities, and it’s possible to implement an affordable, energy efficient system that meets your budget and lasts for decades - even in hot weather cultivation climates. Start by choosing a qualified, experienced mechanical engineer like Surna for your team to help evaluate those options and ensure that you stay on the path to profitability, even under the extreme conditions of the Arizona desert.
