RDWC growing systems

RDWC growing systems

In the panorama of hydroponic growing systems, you have surely heard of the DWC or Deep Water Culture system, which at the time was established as an innovative and efficient cultivation methodology in which the roots of the plants are submerged in a nutrient solution inside a bucket. Challenging the conventions of traditional soil growing, the DWC technique fuses simplicity with effectiveness, offering growers exceptional results, especially in terms of final plant performance.

Well, today we want to present you a variant of this system called RDWC or Recirculating DWC, that is, a DWC cultivation method that includes the recirculation of the nutrient solution between the different containers that house the plants and a central nutrient reservoir. Get ready to fully immerse yourself in the world of hydroponic cultivation with this interesting technique!

How to germinate cannabis seeds in hydroponic and aeroponic systems

How to germinate cannabis seeds in hydroponic and aeroponic systems

The germination of cannabis seeds for hydroponic and aeroponic systems has some peculiarities that must be taken into account. The most important thing will be to carry out the germination process in some inert substrate, preferably in blocks of rockwool or some similar material that cannot release residues.

We must bear in mind that when we want to grow hydro/aero from seeds, germination in soil, jiffy pellets, or coco coir is totally inadvisable since we will fill the system with particles that can easily clog the drippers of the system. For this reason, the cleanest and most advisable thing to do is to germinate or transplant our seeds or cuttings directly into a hydro system or start them in rock wool.

They should never be germinated in soil, since organic matter, being in direct and continuous contact with humidity, would cause diseases of cryptogamic origin such as botrytis, which may cause rotting of the roots and the base of the stem of small seedlings.

Uses for your activated carbon filter

Uses for your activated carbon filter

Activated carbon filters are a very common tool in indoor cannabis facilities, where the intense smell of the plants can often become a problem that is no longer of a domestic nature, but directly in the neighborhood. And it is that these fragrant buds that you like so much can be smelled from tens of meters away, something that you do not want to happen both for safety and, simply, out of respect...smelling fresh marijuana all day can be really annoying even for the most passionate smoker!

In this way, in most cases, the carbon filter is usually installed inside the grow tent or room, so that the air passes through the filter before going through the exhaust fan and being evacuated outside the growing area, normally outdoors and free of telltale aromas. Well, today we come up with several ideas to give your activated carbon filter other uses that can be really useful and avoid some other problems.

Introduction to growing cannabis with LED

Introduction to growing cannabis with LED

LED lamps for growing marijuana

In this post we will focus on the newest LED lighting systems available in our shop. These systems use the energy emitted by light-emitting diodes, hence their name. These diodes do not lose energy when producing light, thus making the most of their power.

As single LEDs do not have enough power on their own, manufacturers design the so-called Led Panels or Led Lamps, these may contain more or fewer units depending on the surface to be cultivated, and available with different configurations. We can highlight that the light spectrum of the LEDs can be adapted according to the user's needs, blue for growth and red for flowering or a mixture of both for the two periods. Modern full-spectrum lamps often produce the best results.

LEDs do not lose power during use, they have a very long life. Besides, the light they emit is continuous and does not cause any stress to the plants.

Nutrients and additives for mother plants

Nutrients and additives for mother plants

Cannabis cultivation and fertilization are two closely linked activities since the improvement in terms of crop yield is more than evident with the use of fertilizers. For this reason, and for decades, fertilizer and additive brands have been striving to create new formulations that are more efficient and cheaper than the previous ones. From rooting products to the most powerful PK boosters for the flowering phase, the offer in this type of product is as wide as it is complete.

Normally, fertilizers are developed for a specific stage of the plant, that is, either growth or flowering. However, how should mother plants that spend months in a vegetative state be fertilized? Do they have the same needs as plants that will only grow a few weeks before flowering? Today we tell you everything you need to know to keep your mother plants in good condition and which products are the best for this purpose.

Cannabis in space: An increasingly closer reality?

Cannabis in space: An increasingly closer reality?

The idea of growing plants in space is probably as old as the idea of visiting this harsh environment. In fact, since the beginning of the space race, in the middle of the Cold War between the US and the USSR, scientists and engineers had in mind the idea of growing crops in spaceships with which the crew could feed themselves and, therefore, open the door to further space travel. However, Kennedy's bet to reach the Moon before the end of the 1960s meant setting aside many projects to focus on a single objective: that an American astronaut land on the moon before a Russian cosmonaut.

However, as you will see in this article, many trials have been carried out in recent decades in the field of growing vegetables in environments with microgravity, or what comes to the same thing, growing in space. From the first tests with control plants to the space lettuce salad eaten a few years ago by astronauts on the International Space Station, things have evolved a lot. They have even started experiments with cannabis...didn't you know? Keep reading...

How to increase the THC level of cannabis plants

How to increase the THC level of cannabis plants

Whether we are talking from a medical or recreational cannabis context, the cannabinoid content becomes more important with each passing season. From users who only want to consume flowers or products rich in CBD but without THC, to the most fanatical fans of strains with high THC content (and, therefore, highly psychoactive/medicinal), as time goes by consumers are gaining experience and are increasingly demanding in terms of knowing the amount of cannabinoids in the seeds or flowers they buy.

Without a doubt, one of the most demanded cannabinoids today is THC. Logically, for a company that markets products with THC or isolated THC, it will be much better to start with plant matter that is very rich in this compound, so varieties that already have a high THC content will be chosen. But how can the total THC production in a cannabis crop be increased? What can be done to increase the THC production of a plant? Today we will tell you about several key aspects to take into account to get as much of this cannabinoid as possible.

LED or HID? Important points to consider

LED or HID? Important points to consider

In today's article, we invite you to reflect on one of the most important aspects of indoor growing: lighting. If you are just starting out in growing, you will have seen that there are several options, not only in terms of lamp power but also in terms of the type of lights you can find. Well, today we will focus on the most popular ones, which are LED panels and traditional HID or high-intensity discharge lamps (HPS, metal halide, etc.).

The intention of this post is not to claim that LED panels are better or worse than other kinds of grow lights, but that they are simply different options (with very wide price ranges) among which the grower will have to choose depending on his needs and growing conditions. However, given the improvements seen in LED equipment in recent years, it is very likely that this type of lamp will dominate the indoor growing market in the near future.

Flushing roots, myth or reality?

Flushing roots, myth or reality?

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.

Vertical farming and cannabis

Vertical farming and cannabis

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.

Green lights for growing cannabis

Green lights for growing cannabis

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.
