8 Ways To Increase Your Cannabis Yields

Congratulations for pursuing the cultivation of cannabis. This hobby can get frustrating if you put months of work into a low yield. We have put together a list of eight tips for getting the most flowers out of your grow.


Growing cannabis is a fine hobby that can secure your personal stash. With months of planning, water and energy usage, you want your plants to produce as many flowers as possible. Find a discrete location where you can cultivate. You can grow outdoors, where you have the advantage of natural sunshine and atmospheric conditions. Growing indoors tends to be more reliable however, as you have a lot more control over that environment. Whichever you choose, there are a number of principles to keep in mind for maximising yields.

First and foremost is the genetics of the strain you’re growing. Luckily, we have a selection of very strong, profit-yielding seeds for you to use. There is also the question of whether you’re seeds are autoflowering or a photoperiodic strain. If it’s the latter, then a very delicate management routine for the plant’s lighting is required for satisfying returns. Order your seeds and get your setup ready to go! Here are eight ways in no particular order to improve the chances of your photoperiodic plant producing a lot of bud.


Sometimes when a plant is struggling to grow, it doesn’t even have the strength to support itself. If cannabis plants have a structure bearing their weight, it can help them advance to a more developed stage. A basic technique of gardening is trellising. This is where wooden structures are built to aid and guide the growth of plants. The material can sometimes be wood, but also bamboo or kinds of metal. Any such strong material can be arranged in a mesh or simply as supportive rods. These can keep your plants separated and sturdy whether you’re grow setup is horizontal or vertical. A bamboo rod could be enough for your cannabis plant to continue flourishing.


As your plant is still vulnerable in the vegetative phase, it is also malleable to training. If you want to guide the development of your plant, this is the phase to do it in. The physical development of your plant could be hampered by branches interlocking from untidy, uneven growth. Subject your plant to low stress training (LST). This is where you spread out the main stem and side branches by separating them carefully with string. This makes your plant grow outwards in a thick bush. String can also be used to keep overlap between your plants tidy. Consider the “screen of green” (ScrOG) method where a grid of string guides the plants towards neater growth.


One obvious way to increase yield is to scale up your production. This doesn’t need to involve taking on more plants than you’re capable of handling. With the plants you have committed to cultivating, you may scale up the equipment you’re using to grow them. For instance, growing in an 11-litre container of soil may produce good yields. Can you afford a 20-litre container instead? With more space for the plant to grow, a bigger yield can be expected. See if your budget can accommodate a boost to your setup’s capabilities. You are making a budget before you start any of this, right? Because that’s so important we hope it didn’t need to be mentioned.


Your budget will definitely be profoundly impacted by your lighting setup. This lighting setup should maximise available light with a direct and evenly distributed light source. There are vertical variations circling around a central light source. There are also rows of plants, sometimes tiered, around a light source from above. Check what distance you should keep your plants from your chosen light. Assuming you have control over your indoor lighting setup, you should research energy-efficient lightbulbs that will cut energy costs and reduce the risk of heat stress. Stepping up the intensity of the light source, although expensive, is going to boost the photosynthetic process further.


Avoiding heat stress and extremes of cold will help your plants avoid damage. Such damage would only drain the plant’s energy, which could be going towards a more plentiful harvest. A big advantage of indoor growing is the ability to control the temperature of your growing environment through a ventilation system. The recommended temperature while receiving light is between 70–85° F, or 21–29° C. The recommended temperature without light is between 58–70° F, or 14–21° C. Humidity is also crucial to monitor, with levels between 50–70% being perfect, depending on the stage of the plant’s development.


Something that will need to be precise throughout every stage of cultivation is nutrition. This includes the high demand for water which must be met. Bare that in mind if you live in a drought-prone region. There are nutrients the plant needs, but be careful not to provide too much of them. Yellow tips on your plant are a sign of too many nutrients, potentially spoiling the plant. A key balance to get right is between the nitrogen, phosphorus and potassium in your fertiliser. During the vegetative stage, there should be high nitrogen, medium phosphorus and high potassium levels. During the flowering stage, there should be low nitrogen, medium-to-high phosphorus and high potassium. It’s also possible to use certain Epsom salts to provide sulphur and magnesium for the plant’s health.


Hopefully your plant is starting to flower and it has many more bountiful buds. Extra care really should pay off with well-managed growing conditions. There is still more work to be done as it nears glorious fruition. Pruning the apical shoot or main stem can allow more than one cola to form. The earlier you do this, the more time your plant will have to heal during the vegetative stage. Cutting a stem can cause two new shoots to form. Cutting the terminal branch tip can cause two lateral branches to form, effectively doubling the space for flower to grow. Remove lower branches which have less chance of flowering well. Soon your plant should have the right distribution of energy.


This leaves one final but very crucial aspect to get right. As your plant enters the flowering stage, the pungent aroma will be strong. You will be tantalised by the months of hard work paying off before your very eyes. If you are patient enough to grow marijuana, then you have the temperament to resist temptation a little longer. Don’t be in a rush to harvest the flower as you may do it too soon and lower your yields. There is a 2–3 week window in which you can harvest the buds. If you hold on for a week or two longer, it can increase the size of buds by up to 25%. It’s worth doing everything you can to maximise your yield, even waiting a little longer.

How to Get a Bigger Cannabis Yield

Today we’re going to give you some hints and tips on how to get a bigger cannabis yield. There are so many factors that come into play when talking about yield, such as how you grow your plants and also how you dry and cure them. With these practical tips and tricks you’ll get some of the biggest yields you’ve ever managed.

To grow cannabis, the plants need to have various factors such as temperature, humidity and light at the right parameters, as well as water, nutrients and a decent substrate. Of course, it’s more complicated than that – routines such as when and how to water can deeply affect the yield you get from your plants if done wrong. If you follow this advice and maintain some healthy habits when it comes to tending to your plants then you’ll ensure that they feed properly and grow to their fullest, making for a better and larger yield.

Something that has a large impact on how much yield you’ll get is the amount of plants that you have per square meter grow tent; if you place too many plants then they won’t be able to grow out wide and they’ll end up growing too tall. If the plants get too tall then the upper part will hardly flower, and the lower parts will get such little light that the buds won’t properly form, so anything you do get from the plant will be of terrible quality. Depending on the strain, you can plant four wide plants, 9 normal plants or 16 plants that only grow out their central stem per square meter – Critical + is a good example of a plant which can easily fit 16 per square meter if you prune the lower branches and leave the central stem and four upper branches. Sometimes you might think you can fit more plants in but they can be deceiving; plants go through quite a growth spurt when they begin flowering and you could end up with a disaster if you don’t calculate the amounts properly. Keep this in mind and you won’t have any over-crowding in your tent.

Apart from the amount of plants, another important thing to keep in mind is the strength of the trunk of the particular strain that you want to plant. The stronger the trunk and branches, the heavier the final yield, so if you train them using stakes or strings, the branches will be tricked into thinking that they’re stronger than they actually are – if plants notice that the weight is getting too much for the branches, then they’ll stop making the buds bigger and begin making the branch stronger, so the idea is to make the branch strong artificially so that the plants keep producing buds. This is a pretty easy way to increase yield.

Another secret to a large yield is using a correct and complete nutritional diet. If you pay any attention to typical commercial brands then you’ll end up using 10 different products and four of them probably do the exact same thing. Plants need various different nutrients as they eat quite a lot, especially plants that are big and have a lot of yield potential. You’ll need a fertilizer base for vegetation and another for flowering, and these two products will be essential for amazing plants. The first few weeks of bloom will need an additive such as a flowering stimulant, and once the flowers have formed you should stop using the stimulant and begin using sugars (Bud Candy + base flowering fertilizer) and your plants’ flowers should get much denser and acquire a thick layer of shiny resin. Once the flowering period advances some more and the flowers are properly formed then you should give them a good dosage of PK such as Monster Bloom, one of my personal favorites, which will cause the buds to grow enormously, nice and full thanks to the sugars. If you’re looking to find out exactly how to feed your plants, you can go check out our article on the subject.

Of course, buying the best nutrients and products won’t do jack if you don’t keep an eye on the pH in your soil and water – an incorrect pH will prevent your plant from being able to absorb minerals in the soil, and they’ll end up accumulating. Any sort of excess in the soil will be extremely damaging to your plants, and they’ll begin showing stains on the leaves which indicate deficiencies or stress which can completely put the break on both growing and flowering. You need to constantly make sure that the pH is adjusted to 5.8 for vegetation and 6.5-6.8 for flowering so that your plant can correctly absorb macro and micro-elements that you give it through irrigation. Also, keep in mind that if you water them too much, oxygen won’t be able to get to the roots meaning that they’ll stop absorbing anything and if you keep doing this the roots can even rot. You need to begin using a quarter liter per plant, and once it drinks that up double the dosage. If everything goes well, when it comes to flowering time you’ll be watering them every day due to their giant root system wanting more and more food.

A decent ventilation system will give your plants the fresh air they need; plants breathe CO2 during the day, so if you don’t set up an air ventilation and renewal system your plants will run out of breathable air rather soon. You can also give your plants some extra CO2 such as Exhale CO2 bags or CO2 bottle kits inside your grow tent – this will decrease the amount of ventilation you need as well as improving your plants’ photosynthesis process and nutrient and water absorption. The result should be an abundant yield using the same equipment you’ve always used and the same light – using CO2 can also speed up flowering, allowing you to harvest a couple of days earlier than usual, sometimes even a week.

If you want to get complicated then you can grow using a maximum yield system; you’ll need to spend a little more time tending to your crops but you’ll be highly rewarded for doing so. There are various systems you can use such as grow wheels or vertical grows, but the easiest one to do without spending a lot on equipment is the SCRoG method. This basically involves bending the branches of one plant to fit them through a mesh placed above the plant, ensuring all of the branches are at the same height, making for a figurative screen of green, full of hard and dense buds. All of the tips of the branches should get the same amount of light. You can see how to use this system and others by clicking here.

There are many ways to get the most out of your plants, but most of them are variations of the previously mentioned advice such as pruning to get wider plants, doubling the branches so that they grow more etc. There are many things that can be done; if you can think of any more or have any questions don’t hesitate to leave a comment and our team of experts will get back to you as soon as possible.
