November 9th, Our Commitment to Sustainability. Being in the indoor ag industry, we view sustainability as an essential part of our company culture. We believe in the importance of taking care of the incredible planet we call home.
That is why we are committed to making sure that we're doing our part to protect the environment. October 12th, What is Indoor Agriculture and Vertical Farming? What is indoor agriculture?
While cannabis cultivators have already been growing indoors for years, vertical farms could be the future of agriculture on an even larger scale. September 8th, MEP engineers provide a wide range of engineering services necessary for any construction project, and they are especially critical when designing an energy efficient Controlled Environment Agriculture CEA grow facility. Here is what you need to know about MEP engineering in indoor farming. June 14th, Indoor agriculture facility design is far more complex than most other construction disciplines.
It requires careful planning and support from specialized experts to set a grow up for success and longevity. A single root, called the radicle, will shoot downwards as the new stem grows upwards pushing the seed out of the soil. Unlike common marijuana leaves, two rounded cotyledon leaves will sprout from the stem as the plant breaks away from the seed's protective casing.
These cotyledon leaves gather energy from sunlight so that the plant can become stable and grow bigger. Once the roots develop, the first true leaves grow and the plant is not in its seedling stage. Seedling Stage The seedling growth stage is fragile and plants must receive hours of sunlight, moist soil, and mild humidity to grow rapidly.
Because the seedling has such a small root system, it's important to not drown it by overwatering. Once a plant becomes a seedling, it will develop more traditional-looking cannabis leaves. A marijuana leaf is made up of anywhere between 3 to 13 fingers.
The leaves produced from a sprout will appear with only one rigged finger. With new growth, marijuana leaves will develop more fingers. Mature marijuana plants will typically have between 5 and 7 fingers per leaf but can reach up to The first fingered leaves can grow up to 4 inches above cotyledon leaves and will have the notorious serrated edges.
This set of leaves grow in pairs on opposite sides of the stem. Cannabis plants are treated as seedlings until they develop leaves with a full number of fingers. Healthy seedlings should be short with thick vegetation and their leaves should appear vibrant green in color.
During this stage, growing environments must be kept clean and free of excess moisture to ensure the plant does not become diseased or moldy.
Vegetative Growth Once a seedling develops 7 sets of pointed leaves, it enters vegetative growth. After being relocated to a larger pot, the growth of a cannabis plant soars. It's stem become thicker and grows taller, it produces more leaves, nodes, and branches, and its root system becomes more established to prepare for flowering. This is the stage where growers will begin topping and training plants. The spacing between nodes displays what kind of cannabis you are growing.
A node is where any two branches intersect off the main stalk. When a plant is young, nodes develop in pairs. When a plant has matured nodes start to alternate. They still develop in pairs but there is more distance between them and branches are no longer parallel to one another. There are also secondary nodes on branches that have developed from the main stalk. Sativa plants are lanky and don't have as many leaves while Indica plants are shorter and denser.
During the vegetation stage, it's important to increase water to aid in the plant's development. As your plant grows larger and the roots grow outward, it's better to water farther away so that the tips of the roots can more easily absorb it. During this stage your plants need an increase in warm water, a flow of dry air, nitrogen and potassium-rich nutrients, and a lot of soil space to allow them to grow feet tall.
Similar to the seedling stage, during vegetative growth, cannabis plants should be in well-drained soil. Leave light intensity the same as what they were exposed to in the vegetative stage. Once your light intensity has reached the level you want for flower and your plants are happy, let them do their thing!
At this stage, you can adjust other environmental variables as needed. Keep in mind that any cultivation changes can impact plant performance as you transition your crop through its life stages. Signs of stress can manifest as leaf drop, chlorosis yellowing of leaves, reddening of leaves, drooping leaves and slow growth. If your crop is showing signs of stress while you make the transition to higher light intensities, lower the light intensity and make more frequent lower intensity increases to complete the transition.

This month he addresses nutrition at the flowering stage. During long light hours of vegetative phase, cannabis is receiving a lot of photon power and wants nutrients to grow fast. With good nutrition, you can see the thin, divided leaves emerging fast and the number of leaflets per leaf increasing, then growing wide — all to capture more light. You can press on the gas or brake pedal of the feed level to grow and establish a plant size you want.
With this growth, the branches established now would have a bearing on the flowering and yield potential later. After shifting to short light period, cannabis bursts into a growth spike. In fact, cannabis puts on most of its mass during this time. Even after shifting, cannabis continues to grow fan leaves for a couple of weeks, and then grows inflorescences.
The bracts are leafy, and thus share similar physiology and nutrition requirements as leaves. So there is no reason to deviate from the nutrient formula. During this time, cannabis needs adequate nutrients not only for the rapid growth of inflorescences, but also for accumulation. When you flush out nutrients from soil, cannabis senses the deficient nutrient condition in the soil and tries to restore the deficiency by moving nutrients from its older, fan leaves to flower buds to meet the nutrient demand from flowers.
Cannabis always tries to ensure that its growing parts have nutrients and in order to so, regulates the movement of nutrients inside.
When extra nutrients are available in soil, cannabis takes in some extra nutrients as a precaution and reserves them for drawing during any future shortage.
