Marijuana Grower's Handbook - Page 4

Hydroponics (from the greek ὕδωρ [hýdōr] = ‘water’, and πόνος [ponos] = ‘work’, ‘labour’) is a farming technique invented centuries ago, since researchers have found evidence that romans and aztecs already used it in their crops and botanical gardens. Probably, the aztecs were the first ones to use this method efficiently, and the study of this technique dates back to 382 B.C. But what is exactly hydroponics?

Hydroponics - also known as soil-less cultivation - is a farming method in which plants are grown in an inert substrate or directly in a nutrient solution. Thus, and with any of the two options, plants are fed via nutrient solution and not via growing medium. Next we'll take a look at the most common hydroponic systems and we'll see how to adapt this technique to marijuana plants.

We recommend using relatively short plants for this technique, since they normally have a very vigorous growth and tall plants may become a problem in indoor grow tents with this system. Philosopher Seeds recommends using the following strains to get the best results with hydroponic systems, even from seed: Black Bomb, Heaven's Fruit, Tropimango, Sugar Pop, Orange Candy and Guava Berry Kush.

While thrips (insects of the Thysanoptera order) are not usually a serious thread for our crops, thay can be a pain in the neck if not identified and treated on time, especially when propagation conditions are optimal. These small flying insects are usually found in indoor grow rooms and greenhouses, where the warm temperatures greatly promote their propagation. They attack a vast number of plants like cereals, fruits, vegetables, etc.

Next we'll tell you what are thrips, how they reproduce and what should we do to avoid an infestation of these tiny insects on our marijuana plants. At the end of this post, you'll also see a spectacular video of a thrip eating spores of powdery mildew on a cannabis leaf.

In this post we will present 5 feminized cannabis varieties/ strains that are perfectly suited to outdoor growing. All strains in our catalog are suitable for exterior growing but we are discussing the most productive here. We have included a picture gallery of outside Guerilla grows at the end of this article.

Although not the most productive, we should remember that Early Maroc is a perfect choice for outdoor Guerrilla grows particularly because of its extremely precocious /premature character and low water requirements. For more information about this variety, we recommend reading this post: variety of fast marijuana

Powdery Mildew ia a fungal disease which mainly attacks plant leaves. There are many species that can be attacked by Powdery Mildew, such as roses, carnations, tomatos, strawberries, cucurbits, apple trees, plum trees and, of course, cannabis. It can be devastating for marijuana if not treated early, since it reaches the buds and ruins its flavour.

The electrical installation of our indoor cannabis grow room is a key aspect if we want an efficient and safe power system, so we should not forget its importance. The Philosopher Seeds cannabis seed bank recommends you to carefully read this post and ask a trusted electrician in case of doubt. If the installation of our grow room is not correctly done or is not in line with the electrical installation of the building - or the contracted power - we can have problems. This is why everything must be clear and we'll always avoid hasty solutions. Of course, using certified and approved materials is also a must.

In this post we tell you some of the most important details relating electricity and indoor cannabis gardening; from the most theorical concepts to how to calculate the cost of each electrical device. Let's go into detail now.

Today, coco coir is the favourite substrate of many growers for growing cannabis, either indoors or outdoors. Although it is mainly used by experienced farmers, growing with coco coir is easy if you follow a few basic steps. Using EC and pH meters is almost mandatory if you choose this media, since you have to carefully check this values before watering your plants. In this post we tell you a few tips to successfully harvest your plants with coco coir.

All the pictures you’ll see were taken from Amnesika 2.0 crops, both in pots and coco slabs.

We can use cannabis in different ways: edibles, smoking or vaping.  In this post we tell you more about vaporizing, which are its benefits and which Philosopher Seeds cannabis strains are ideal for a unique vaping experience. We’ll also check some of the most popular vaporizers among vapers worldwide.

What is cannabis vaporization?

Vaporization or vaping consists of heating the plant material below its combustion temperature (220-240ºC) and inhale the vapours released. The ideal vaping temperature of cannabis is 180-210ºC.

Plants with microscopic mites

Cannabis crops need optimal temperature and humidity parameters in order to remain free from pests and molds, otherwise they might be attacked by many infections. Knowing the different pests that may attack our plants is crucial for choosing the correct treatment for each type of pest. This is why you should always have a magnifying glass at hand to check both the surface and the underside of the leafs, so you can detect any parasite on your plants.

As usual, the Philosopher Seeds team wants to help you with its cannabis strains to prevent and identify any type of pest that could attack your crops.

At the end of this post you can check a gallery with pictures of cannabis plants with symptoms of microscopic mites. In this case, the pictures were taken from an Amnesika 2.0 grow which was attacked by these mites. Despite being an uncommon pest, any plant from any variety is sensitive to microscopic mites, so remaining vigilant is advised.

Keeping a genetic reserve of mother plants in an indoor cannabis grow room for a long period of time requires proper care to keep them in good health. Generally, this technique is also used so mother plants produce more quality cuttings.

Cannabis is an annual plant, so if we plan to keep it in growth stage we need to follow certain steps in order to keep it healthy and strong. Some marijuana strains are more demanding than others, but all of them enjoy having a lush root ball; it is then the grower's job to take care of the root system of the plants so they can show their full potential, always under optimal conditions.

The first stage for any grower is germinating the seeds. To achieve best results, we should use healthy, quality cannabis seeds. All seeds from Philosopher Seeds come in labeled packages with a batch identification number, so the product tracking is much easier.

Although seeds do not need much to germinate, we do have to consider a few basic aspects to be successful. It’s kind of a prenatal stage in which the grower has to be very careful to meet the few needs of the seeds during this phase.

What are terpenes?

Terpenes are organic compounds which act as aroma precusors in plants. Most terpenes are produced by an hydrocarbon called Isoprene (2-methyl-1,3-butadiene) which can be found in both animals and plants, also in the human body. The amount of isoprene found in cannabis plants (actually in all plants) mainly depends on light and environmental conditions, besides other factors.

Otto Wallach, a 19th-century German chemist, was one of the first scientists ever to investigate terpenes, leaving a knowledge that has been used later on in the essential oils and perfume industry, being the former used in alternative therapies.

Indoor cannabis cultivation is often seen as something difficult that can only be performed by specialists. Well, nothing could be further from the truth, since growing our favourite cannabis strains indoors is easy if we follow few simple instructions and are a bit constant.

In this post we'll tell you in an easy and simple way how to build an indoor grow room, focusing on three important aspects: ventilation, nutrition/medium and the lighting system. If we keep these three elements under control and choose correctly our strains, indoor cultivation can become something simple and almost mechanical, although if we neglect some of them, both yields and quality can be seriously diminished.

For this post we used a 1,2 x 1,2 metres grow tent, with 2 metres of height. In the market we can find lots of different grow tent models, so finding the one that best fits into our growing space should be easy. In this way, controlling the temperature and humidity of the environment will be easier, besides keeping our plants away from external light sources that could interrupt the night period of our plants, something vital for a good flowering.

Cannabis is a psychoactive, herbaceous, annual plant, of the Urticales (nettles) order and belongs to the Cannabaceae family. Its origins bring us near  the Himalaya mountains, between China and India, where from it extended to the rest of the world making viable its growing thanks to the infinity of medicinal, recreational and industrial uses that have this millennial plant.

Cannabis sativa (mainly coming from tropical areas such as South and Central America, Africa, Thailand and South of India) was classified for the first time in 1753 by the Swedish scientist, naturalist and zoologist Carl Nilsson Linaeus, who suggested the current binomial of nomenclature diagram.

On the other hand, Indica Cannabis, comes from the Himalaya mountains (Afghanistan, Pakistan, etc. ) and was described and classified for the first time by the French naturalist Jean-Baptiste Lamarck in 1783, who also developed the first evolution theory.

A third and last sort, of which later was created the automatic marijuana strains, coming from Russia and North Kazakhstan was discovered in 1924 by the Russian botanist D.E. Janischevisky and called cannabis Ruderalis.

This post will be interesting for both indoor and outdoor growers, although if we want to search for phenotypes and keep mother plants - clone mothers - we'll need an indoor growing space.

We'll see how to keep a copy of the different phenotypes, how to select them and how to grow them again anytime we want, getting the same exact product than in previous crops, exactly the same as the mother plant.

The selection process can be performed with either feminised or regular seeds; as long as they are photoperiod strains, we'll have no problems in keeping them growing under the correct light schedule. Thus, we can not clone autoflowering plants. Female Viagra online http://www.healthfirstpharmacy.net/female-viagra.html

You'll also see, step by step, how to make cannabis cuttings. As happens with any selection, it ended in a splendid cannabis tasting session.

With the results of the tasting at hand, it is much easier choosing the best phenotype, so we'll finally have our mother plant.  All the pictures from this post were taken during a selection of SuperJuani seeds.
