How to use nutrients and additives for growing cannabis?

Just as humans require an appropriate and balanced diet,< our plants need it too and this nutrition should be provided regularly and in a balanced way both in terms of quantity and quality. Normally, the fertilizers for cannabis plants are available in either liquid or solid format.

Today we are going to tell you how to use these plant nutrients in the best possible way to have healthy plants grown in soil, with awesome results, and without nutrient imbalances of any kind.

For years, the belief that irrigating with just water during the last two weeks of cultivation removes nutrients from the substrate and, above all, from the plant, was a topic that few people would have dared to disagree with. The general trend claimed (without any scientific basis apart from subjective opinions) that if during this last period of ripening water only was used for irrigation and no fertilisers were used, the plant would consume the nutrients from the soil and, when these were finished, it would use the nutrients stored in its tissues, greatly improving the flavour and aroma of the finished flowers once dry.

Thus, this technique - usually called "root flushing" - was given a series of benefits in terms of the quality of the final product: superior organoleptic qualities than in the case of not flushing, combustion without crackling, white ash and a long etcetera of properties that, although they had no scientific basis whatsoever, were commonly accepted without major reservations. However, over the last few years, a series of scientific studies have appeared that call these claims into question, which has only ignited a passionate debate between detractors and supporters of root flushing. Today, based on these two studies, we propose to enter into this debate and try to work out whether or not it is worthwhile to apply this traditional cultivation technique.

When growing cannabis indoors, the classic approach is to grow horizontally (or flatbed), generally using square or rectangular trays (depending on the shape and size of the grow tent or room), with the pots containing the plants placed side by side. Horizontally, one grow light is normally used to illuminate each square metre; and the plants are usually arranged in a “stadium shape” to take better advantage of the light: with the shortest plants placed in the centre and the highest around the sides.

However, every experienced grower knows that the maximum light output is still not always achieved and that many plants do not receive the amount of light they should. For this reason, vertical cultivation is an excellent tool for those who want to make the most of their resources indoors. Because vertical growth, when done correctly, can increase yields and maximise efficiency.

In many ways, it is a game-changer as the boundaries of innovation are being pushed upward. Vertical growing techniques provide opportunities that are unimaginable with traditional horizontal cultivation, particularly in more mature markets such as the USA, where commercial cannabis growers seek to improve yields, reduce costs and maximise space.

Vertical farming: less is more

The vertical cultivation technique is the practice of growing plants in vertically stacked layers or sloping surfaces; It consists of placing the cannabis plants on shelves, walls, or in columns, with the light source placed in the centre or on each individual shelf layer. In this way, it is possible to take better advantage of the space and ensure that more light reaches all the plants, thus achieving a higher yield. It's all about maximising harvests while using the minimum available space.

Normally, when growing indoors, we use blue light for the vegetative growth phase and red light during flowering. Selecting the type of light and its appropriate colour temperature (usually known as its spectrum) is vital when it comes to getting the best results from an indoor grow. However, there is another type of light that is still unknown to a lot of growers and, although it doesn't directly influence the development of plants like the ones we just mentioned, it can be really useful for growers to prevent potential plant problems: green light.

Although as a grow shop we sell all kinds of products related to cultivation, from the most modern hydroponic systems to ranges of completely organic nutrients, at Alchimia we know that caring for the environment is very important and we always try to offer you not only the products necessary to carry out organic farming but also the information on how to ensure that your cultivation has the least possible negative impact on nature.

As with almost any other type of cultivation, cannabis farming is not exempt from bad practices and can potentially be disastrous for the environment, much more damaging than if other types of methods are followed. Growing sustainably isn't simply a matter of switching to a specific type of substrate or fertiliser, but of analysing our growing practices from start to finish, taking into account the carbon footprint of each product, input and even of the techniques that we use. We've already examined our own methodology from this point of view, and we'd love to share the conclusions we have reached with you. By protecting the environment we are protecting ourselves, and as you'll see, it's easier than you might think!

Micropropagation is one of the most widespread uses of in vitro plant cultivation. These techniques and tissue culture methods are used to multiply genetically identical plants (known as clones) on a large scale, in reduced spaces and short periods of time, combining some of the advantages of both systems of plant reproduction.

This method of in vitro plant propagation is one of the plant biotechnology cultivation techniques that has shown a huge rise in popularity in recent years, as it allows growers to obtain thousands of identical plants from very small sections of a mother plant, called explants. The success of any micropropagation will depend on the ability to acclimatise high-quality plants from in vitro conditions to ex vitro conditions, thus producing new plants from these explants.

In this article, we'd like to take a closer look at the fascinating world of tissue culture, outlining the possible applications that this technique offers to cannabis cultivation which, as you'll see, are quite a few!

When setting up your first indoor grow, the first few things to consider is the space you have available - whether it's a room or a grow tent - the lighting system needed, and the number of plants you can fit in that space. Many times, people don’t take into account the relevance of proper air exchange and how vital it is to achieve a successful harvest.

This article will help you to understand this important factor, and to decide which exhaust fan is more adequate for your grow room, so it works as efficiently as possible without wasting power.

Environmental conditions play a vital role in successful indoor cannabis grows. It goes without saying that the right temperatures are essential for growing healthy plants, but if you want to further optimize your indoor growing space, you shouldn?t ignore the importance of relative humidity in relation to the plant?s life stage.

The right humidity levels allow a faster plant development, which translates into shorter growing periods, but also into healthier plants thanks to better nutrient absorption and assimilation. It?s a great way to make the most of your indoor setup and get maximum yields.

Whether in an outdoor indoor cultivation, transplanting cannabis is a sensitive phase in the life of your plants, which need enough space to develop an extensive root system in order to reach their full potential. A plant with little room for its roots will never perform as well as another with a well-developed root ball! For this reason, it?s a very important moment for the plant growth, and you must transplant your marijuana at the right time and into the right pots.

Today we are going to take a closer look into this operation, which must be carried out with utmost care in order to minimize the stress caused to the plant. If you do it right, you will be able to make the most of the available space, save substrate and nutrients, reduce the risk of fungi, accelerate plant development, and obtain maximum yields... It?s worth trying, don?t you think? Let's do it!

As we all know, cannabis is an annual plant that goes through different stages during its life cycle; from germination, growth and flowering, to harvest. After harvesting your marijuana buds, you can no longer benefit from the plant or its genetics, unless you remembered to take some cuttings during the vegetative phase.

What happens when you realize too late, during the flowering period, that you should have taken some cuttings from that specimen of unique nature?

Now that the heat of summer is upon us, and before it ends, many growers will decide to shut down their indoor grow operations until conditions cool down in the autumn. This is partly because their attention shifts towards growing outdoors while the weather is favourable, but it's also because of the increase in ambient temperatures. The hot days, combined with the heat produced by powerful grow lamps, make it a real challenge to maintain the ideal conditions in our indoor garden. With the advent of good quality LED lights and affordable air conditioning these problems are somewhat reduced, but even so, much of Europe still gets far too hot to allow trouble-free indoor cultivation in summer.

So, while your indoor grow area is temporarily out of commission, there's no better opportunity to give your grow tent a thorough deep clean and at the same time double-check that all your equipment is in perfect working order so you're prepared for the much anticipated first crop of the autumn!

CO², also known as carbon dioxide, occurs naturally in the atmosphere at a ratio of 300/400ppm. Bearing in mind this is the main inorganic component used by cannabis plants to build their tissues, an additional provision of CO² with the right assimilation conditions will result in faster, more robust and productive marijuana plants.

The key to successful cannabis growing lies in proper plant nutrition. It's true that every environmental factor should be adequately laid down in order to maximize the outcome of your crop: air exchange, type of lighting, temperature, humidity, etc. However, it would be pointless to choose a complete and balanced range of fertilizers if you are not taking into account the pH of the nutrient solution, or in other words, the acidity or alkalinity level in the feed you are giving to your plants.

To ensure proper nutrient uptake through the plant's root system, each macro and micronutrient in the marijuana feed must be administered with regard to a particular acidity value (pH), otherwise the absorption won't be adequate. This factor is very important to make the most of the fertilizers and to prevent nutrient deficiencies and overfeeding problems, thus obtaining a bountiful harvest.
