Marijuana Needs Nutrients to Grow

Marijuana needs Macronutrients to Grow:

Macronutrients Medical Marijuana

Macronutrients are the elements necessary for your plants to grow large properly. The most heavily required macronutrients for all plants are (NPK):

  • Nitrogen– Plays a critical role in photosynthesis as it facilitates the production of chlorophyll and amino acids. A nitrogen deficiency is identifiable when the cannabis leaves begin to turn a pale yellow and eventually droop as the plant dies.
  • Phosphorus– Especially important in the process of photosynthesis, a cannabis plant’s metabolism, and the ability for the plant to absorb nutrients. A phosphorous deficiency makes plants more vulnerable to pathogens and is identified by leaf discoloration from green to a purple-reddish hue.
  • Potassium – Helps plants grow earlier, fight disease better, and use water more efficiently. Plants malnourished in potassium will show this deficiency with yellowing leaves. However, a potassium deficiency distinguishes itself through the location of the yellowing; yellowing begins at the leaf’s edges.

In lesser quantities, cannabis plants also require secondary nutrients:

When your purchasing cannabis nutrients, you should see an NPK ratio listed will always be listed in the order of nitrogen, phosphorus, and potassium.

These three are the most important for healthy growth, though the ratio will change as your plants develop.

Vegetative stage, a ratio of 3-1-2 is recommended, though there are always variations others have success with. The most important thing is that the nitrogen content is higher than phosphorus and potassium. Higher nitrogen content is required for photosynthesis, a necessary process for the development of the plant during the vegetative stage.

Flowering stage, you’ll need to lower the nitrogen content and raise the levels of phosphorus and potassium. While it varies by specific strain, we recommend a ratio of 1-4-5, though others seem to have success with slightly different ratios as long as the nitrogen content has been significantly reduced.

The secondary nutrients calcium, magnesium, and sulfur, all are required in lesser amounts for healthy growth. These are typically provided by the soil, so it’s important to adjust if you’re growing with hydroponics.

Micronutrients for Growing 

Micronutrients are important for growth, but they’re not nearly as crucial as NPK and are required in much smaller amounts. Still, if your plants lack these elements they may become unhealthy. Necessary micronutrients include:

Soil vs. Hydroponic Nutrients

Whether you’re growing in soil or hydroponically will determine the right kind of nutrients you’ll need to use. Nutrient solutions vary, and using the wrong kind can damage your plants.

Soil Nutrients

While chemical fertilizers may be tempting, they diminish the soil quality over time and are not good for your soil in the long-run. We recommend using organic fertilizers in your grow because they’ll produce a better tasting and healthier plant.

You can either purchase pre-made organic fertilizer mixes or get your hands on the necessary components and add them yourself. If you’re still new to growing cannabis, using an already-made mixture from the store may be your best option because you won’t have to worry about ratios and application methods and can instead just fertilize your plants as directed.

If you want to go the DIY route, some options are:

Hydroponic Nutrients

Without soil, the addition of nutrients is more crucial to grow healthy plants. They will still require the same necessary nutrients as if they were grown in soil, they’ll just need you to provide them in a consistent way.

One benefit of growing hydroponically is the ability to control the type of nutrients and the portions given. Just make sure your nutrient mix does not contain organic matter, as this can harm your plants and clog the system.

Healthy soil typically provides the necessary micronutrients for cannabis plants without extra supplementation, but in hydroponic growing systems, micronutrients will need to be added. Make sure your nutrient mix has all the components for healthy plants included to prevent any deficiencies.

How Cannabis Absorbs And Transports Nutrients

How plants absorb NPK

Nutrients are absorbed in the roots through osmosis. In plants, osmosis refers to the transfer of ions from water through the plant’s cell wall and into the cell. This osmotic pressure—the movement of nutrient ions during osmosis—is a smart process. Osmotic pressure moves according to the concentration of nutrients on each side, from the side with the highest concentration of ions to the one with the lowest.

For example, when the cannabis plant uses phosphorus, the concentration of that ion is lower on the plant cell side than it is on the waterside. Osmotic pressure then enables the plant to absorb phosphorus from the water. If the concentration of phosphorus is the same inside of the plant cell as it is in the water, nothing happens. There is no osmotic pressure. However, if there are more ions in the plant cell than there are in the water, the phosphorous will transfer to the water to create balance, causing a phosphorous deficiency.

Once the nutrients are absorbed by the roots into the plant cells, they must move upward through the plant to get their work done. The pressure created by salts and oxygen present in the water as well as the leaves’ pores enable the nutrients to move through the cannabis plant.

There are factors that can slow or stop the absorption and movement of nutrients. 

If the humidity is too high, the leaves will struggle to create the right amount of pressure through evaporation, and the plant will absorb fewer nutrients. If it is too hot, too much water may evaporate, and the plant will lose nutrients as a result of this excess evaporation. This is why keeping cannabis at the right temperature is so important. Reducing the plant’s sweating allows it to use the nutrients you’ve worked so hard to provide it.

The materials you feed your plants with are converted into energy and the nutrients needed to create new plant cells and maintain existing ones. The type of plant cells created depends on the stage of growth the plant is in; hence the different N-P-K ratios for each phase of cannabis growth.

Final Tips

The biggest factor in deciding the best marijuana nutrients for growing weed will depend on whether you’re growing in soil or hydroponically, so sort that out before picking up goodies for your plant. The stage your plants are in is also crucial to pay attention to, as plants in the vegetative stage need high levels of certain nutrients while requiring smaller amounts in the flowering stage.

Your exact method will depend on many factors, such as growing medium, level of experience, and whether you want to be more in control of the process or just get a pre-made solution that will take care of it. Whatever you decide, the bottom line is that you’ll probably need to do some experimenting before nailing the perfect nutrient solution, and that’s okay.

What to do After Your Seed Sprouts

How do you care for your plants through their different stages of growth? Cannabis plants will go through a seedling, vegetative, and flowering stage. Each stage is unique, so it is crucial to understand each part of the growth cycle to produce healthy plants.

Your cannabis seeds have successfully sprouted, time to be planted in your chosen medium. Just a few millimeters below the surface of your medium. Your little plant babies are delicate and easily damaged. So handle them with care. Plant them with the roots facing downwards as an easy way to give them stability.

The Seedling Stage

In this stage, cannabis in the seedling stage does not require intense lighting setup. Compact fluorescent lights or LEDs will work. The optimal light cycle for seedlings is 18 hours on and six hours off.

Remember seedlings are tiny and fragile, so you should water them accordingly. Major Rookie move is overwatering your seedlings that can wreak havoc on your whole operation. The temperature of the room you have set up to grow stays between 68 and 77 degrees known as the sweet spot. Important at this stage is humidity and some growers may use humidity domes to keep the seedlings in their comfort zone.

Seedlings may be managed in small containers later transplant them to their permanent container during the vegetative stage is common. This stage normally last about two to three weeks.

Vegetative State

This stage is where growing gets exciting. The vegetative stage is when the plants have developed strong roots and leaves. If you are transplanting them into their bigger containers be careful. In this stage you will see rapid growth.

In this plant growth cycle you may see a series where new leaves pop up frequently, usually stopping at around 10 leaves. Branches may even start to develop, and expand in new directions. Space your plants according to their expected growth depending on if you choose indica, sativa, or hybrid. The vegetative stage, is where you can begin to train your plants by pinching or topping them, which typically ends up increasing your yields.

The more sunlight your plants have they will stay in the vegetative stage longer. Growing indoors allows you complete control on how long they stay in this stage. If you want them to stay in the vegetative stage and not flower, you can keep them in the same light cycle as the seedling stage (18 hours on, six hours off). If space is an issue, be careful how long you keep your plants in the vegetative stage. The longer they are kept without flowering, the larger the plants will become. Typically plants stay in this stage from three to 16 weeks.

Keep the Males Away

Very Important stage when moving to the flowering stage, be sure to determine if you have any male plants in the mix. If you do; you’ll want to throw them out because they will try to pollinate your plants, forcing the females to produce seeds. You’re trying to get them to flower, not go to seed.

Please refer back to the "Difference between male and female cannabis" Blog if you need too.

Female plants have pointy green calyxes, tear-shaped flowers that grow little white pistils.

Males will not have this characteristic and instead will have small pockets filled with pollen.

Make sure you separate any males from your bunch before the pockets of pollen burst.

Feminized cannabis seeds should be used if you don’t want to deal with separating the male plants out.

Flowering Stage

If you have made it this far pat yourself on the back. The final stage begins in flowering when you cut back on the light, reducing it to around 10-12 hours per day. When you adjust the light, plants will sometimes have a growth spurt as they anticipate the coming of winter. Be sure to have enough space.

When your plants begin to develop resiny buds. It is going to require more nutrients. It’s important to not abruptly make changes to your schedule, but instead, ease from using growing to flowering nutrients over the course of a week or so.

Normally around the third or fourth week of flowering, your plants will stop growing altogether. Now they can focus all of their energy on making dense, aromatic buds loaded with trichomes.

Harvest time will vary, but somewhere between week six and eight is a good time to prepare. Determining harvest time by looking at the pistils and trichomes on your plants.

(Don’t rely on number of weeks to know when you should harvest, too many factors are at play). The pistils, or tiny hairs, should change from white to yellow until they are finally brown. This will vary slightly depending on the strain you are growing. A heavily-magnified item such as a jeweler’s loupe can be used to zoom in to the tiny appendages of your trichomes. The color is extremely important! 

Clear trichomes mean the plant is not ready.

Milky means they are at peak THC levels.

Amber means they are beginning to decrease in THC levels.

Tips For Successful Indoor Growth

Follow directions as labeled on your nutrients and check for specific variations in growth for the strain you plan to harvest. Don’t prune your plants after a few weeks into the flowering stage as it can throw off their hormonal processes. It’s important to stick to your light regimen precisely, as exposing your plants to light during their typical cycle of darkness can mess up the flowering stage. If you can’t stop yourself from peeking at your plants during their “night”, you’re going to hurt your yield.

How to pick Your Space, Choosing Your Lights

First Step To Growing Cannabis Is Setting Up Your Grow Space:

You can not learn how to grow weed indoors in a day. It’s a process which requires you to take time, energy and money to set up properly. In addition; the amount of information available on the web on the subject of growing weed can be overwhelming and convoluted.

Picking Your Space:

Growing weed indoors means you control the space and control climate. It will take time to nail your method, so you can maximize your harvest and reap the benefits.

You can begin growing in a small closet, a basement, or even a bedroom that doesn’t get much attention. Make sure you consider your options fully, because there are a few things you need to keep in mind when choosing the right space.


If you’re just learning how to grow weed, Start small you don’t need to go all out for your first time. In fact, you will save yourself a lot of stress. You can always expand your space to accommodate more in the future. Like any plant, marijuana is susceptible to pests and conditions that can effectively wipe out your crop. Losing a couple of plants will be less painful emotionally and financially than losing a whole garden. You’ll need a room with decent height, as cannabis plants love to double or even triple in size.


Marijuana plants can be picky, and if you aren’t growing in a temperature they thrive in, the plants will become stressed out. Remember depending on the lights you add to the setup may increase your temperature as well.


Ideally, fresh air from outside is the best option. You can choose a room that offers easy access to a window or an adjacent room you can cycle air through. As you start to expand your operation, you will want to invest in a proper ventilation setup, but that won’t be necessary if you’re just learning how to grow weed. 


Your plants will be exposed to a light cycle, and preventing light leaks is imperative to proper flowering. Therefore, you must choose a space that can easily seal away light.

Discretion and Convenience:

Our state law in Missouri, requires to keep your cannabis in a locked-away area. Since lighting is a big issue You don’t want every person who enters your home to know you are cultivating cannabis.

Choosing Your Lights to Grow Weed Indoors

The lighting you choose for your indoor weed operation is going to make or break your setup. It’s important to choose the best quality possible. 

Grow Medical Marijuana Indoors Light
High-Intensity Discharge (HID) Lights

Are known to get very hot and usually require an exhaust fan to keep the temperature under control.

Metal Halide (MH)

These produce a soft, bluish light that vegetative plants can’t get enough of. Therefore, the light can be used throughout the whole harvest, including the flowering stage.

High-Pressure Sodium (HPS)

These lights are more used for the flowering stage because the yellow light encourages high bud production. The lights get the best yields per watt of energy, making them a top choice for efficient production.

If you can’t get yourself a combination of the two, start with HPS lights as they are more energy-efficient.

Fluorescent Grow Lights

A good choice for a shorter room because they can be positioned close to plants because they don’t produce a lot of heat. These lights are easy to get a hold of, produce little heat and use little electricity. Fluorescent lights are not super efficient for growing weed since their light can’t travel too far down into the plants, though. They are affordable and don’t require a ventilation system.

LED Grow Lights

For small harvests, or for people just learning how to grow weed, they can be a good choice without any complications. LED lights tend to use less electricity and run cooler, allowing growers to sometimes skip a ventilation system altogether. They’re easy to set up, and just need to be plugged into the wall and hung over the plants. Do some research on the ones you want. They can be a great addition to your setup, but you have to be careful to buy good quality.

Average Grow Period for Cannabis

What’s the Average Grow Period for Cannabis?

Average Grow Period for Sativa, Indica, and Hybrid Strains of Cannabis 

Average Grow Period for Cannabis

Being a cannabis consumer growing your own weed can be one of the most rewarding aspects. It is vital that you know and understand that when it comes to growing all strains aren't created equal.

Sativa, Indica, and hybrid strains all grow differently and have varying degrees of time it takes to flower. Are you aware of the different growing periods for each? It is important to know the average grow period and differences of growing each strain.

The Life Cycle of Cannabis Plants

Once your seeds have been sown and your cannabis plant has become a little baby seedling. After that; it will experience two major stages of life; known as the vegetative stage (when plants are growing) and the flowering stage (where plants are producing buds).

The Seedling stage:

Can last anywhere from 3-6 weeks.

The Vegetative Stage

This is where your plant begins to grow, and grow, producing those big jagged leaves cannabis is famous for.

Did you know a healthy pot plant can grow up to 2 inches in one day if you did everything right. Whether sativa, indica, or hybrid, this is the time when the roots of your cannabis plant continue to expand, and your plant continues to grow larger.

The length of time a plant is in the vegetative stage is completely dependent on its exposure to light. Growing cannabis indoors, means you can manipulate your light cycle, essentially keeping plants in the vegetative state as long as you want. To keep a plant in vegetative without flowering, it

Should receive under 18 hours of light and 6 hours of darkness. The longer your plants stay in a vegetative state, the bigger your plants will get, so you will need space.

Flowering Stage

The flowering stage of cannabis is when your plants start to produce the flowers that will eventually become the buds you harvest. It's also the stage of a cannabis plant occurs after light exposure's reduced. Where cannabis plants will stay in veg forever if they’re kept under light for 18 hours a day, switching the light cycle to 12 hours of light and 12 hours of darkness will initiate the flowering stage.

The average cannabis flower time is 6-10 weeks and sometimes longer. The length of time plants are in flower depends on the type of cannabis you’re growing as well as the conditions you’re growing in.

The normal grow period for Sativa, Indica, and Hybrid:

Sativa Flowering Time to Fully Grown Plant

Sativa strains of cannabis usually grow: long, tall, and lanky. Secondly; sativa stem is from regions near the equator, where the length of the day rarely changes regardless of what time of year it happens to be. Equal days and equal nights have led sativa strains to grow in short, consistent photoperiods. This simply means that the height of a sativa plant increases during both vegetative and flower periods.

Pure sativa strains can grow to heights of 20 feet due to growing so tall, indoor growers generally stick to indica strains instead. Sativa typically has a shorter vegetative cycle, but once the plant begins to flower it can take up to 10-12 weeks until it is ready for harvest. A pure sativa strain take 16 weeks to finish in flower.

The growing period for pure sativa strains is around six months.

Indica Flowering Time to Fully Grown Plant

Popular choice for many experienced growers. Indica strains grow short and fat and typically yield more than their tall, lanky sativa counterparts. They are also known to have shorter flowering periods than sativas. Because indicas have a shorter flower period, indoor growers can have more annual cycles. The flowering period for indica strains is typically around 8 weeks. If you’re growing indica, you can expect your plants to be in flower for 8-12 weeks.

Hybrid Flowering Time to Fully Grown Plant

Hybrids are a blend of sativa and indica cannabis strains. Also, hybrid cannabis strains are a blend of both indica and sativa, when cultivated they typically take on traits of one or the other. Much like sativa strains, hybrid strains can grow quickly during the vegetative stage. When it comes time to flower however, they may take on the shorter flower periods common to pure indica strains. Typically, hybrid strains will stay in flower for 6-10 weeks until ready for harvest.

By growing indoors, you manipulate your environment a bit more. Overall, the average growing period for all types of cannabis, sativa, indica, and hybrids included is around 3-6 months depending on the environment you’re growing in. To stay updated on the Medical Marijuana Cannabis laws and regulations check out the DHSS website.

How To Grow Marijuana (weed) Indoors 

Choosing A Strain and Choosing A Medium

Choosing a strain is one of the most important and fun parts of growing Marijuana, but there is a lot to consider. Those learning how to grow marijuana for the first time must think about the space the cannabis plants will be occupying, the desired effects from the plant, and more. 

Choosing a Strain

The strain that you want to grow will in large part depend on how big the space you chose. If you have a large room with high ceilings, you can get away with most varieties. If you are growing in a more discreet manner you should go for plants that are known to grow short such as indica or hybrids.

Sativa vs Indica Traits

Sativa plants tend to grow tall as they flower. They can handle heat better than indica strains can, but they suffer in the cold. So temperature is a big deal. Their buds grow long and produce a light, uplifting effect.

Indica plants are more likely to be short and compact, taking up less space. Sativa plants, they do not do well in the heat and are best suited in a cold environment. They produce dense buds that offer a heavier, more relaxed effect.

If you don’t want to choose between sativa or indica, you could go for a hybrid. These blend traits from both sativa and indica plants, with one being dominant or just a 50/50 split. With hybrids, it’s possible to have less flowering time as you’d expect with indica, while still achieving the energizing effects of a sativa strain. Hybrids blend features of both plants in many different ways, leaving a lot of options for customizing your growth.

Selecting a Grow Medium

The growing medium is where your plant roots are going to develop and grow.


This one is an obvious choice since it is natural and easy to set up. You need balanced, organic living soil to get the best results. The plants rely on the nutrients in the soil to help them grow.


Soil-less growth is possible, so long as you’re keeping up with feeding nutrients to the plant. With hydroponic grow mediums, users can precisely dose out nutrients to their plants, often resulting in better, healthier yields. Hydroponic systems come in many different mediums, such as clay pellets, rockwool or vermiculite. It’s for this reason that people often use hydroponics for growing clones as well.

Germinating Your Seeds

You’ve selected your strain and in what medium, and it’s now time to get the operation started. Once you have all your ducks in a row, it’s time to germinate cannabis seeds.

Seeds require air, heat, and water to germinate. The simplest and most common method is to use a wet paper towel and a plate or sealable container.

To germinate your seeds, you will need to wet some paper towels with plain water. Get them thoroughly soaked, without water dripping excessively. You do not want the paper towels to just be damp. Then, place the paper towels on the plate or in the container, and carefully place the seeds about an inch away from one another.

Once you’ve laid the seeds out with good distance between them, you can cover them with more wet paper towels. Then, you can place either a bowl or second plate over the plate to create a dark and contained area, or partially seal up your container (leave some airflow) and place it somewhere dark and warm.

The seeds will need to stay somewhere between 70 and 90 degrees to successfully germinate. You will know they are ready when they have sprouted. Expect anywhere from 24 hours to a few days, though some seeds will germinate more rapidly than that. You can periodically add some water to the paper towels if they dry up quickly.
