But I am also convinced that, although you know some things about Neem Oil, maybe you need to look into the last hints about Neem Oil applications, otherwise you wouldn’t be reading this post. I’m not mistaken, right?

A brief introduction

Of course, I am not trying to make this article into an encyclopedia or the great guide about Neem oil, but I would like to seize the following lines to share with you all things or at least many subjects that, over the years, I have been learning about Neem oil and also all the benefits its use brings us in the crops and, in particular, marijuana crop, which now is the most important to you and me, isn’t it?

Would you like to accompany me? I will love finally you do and I will like much more, that at the end of the text you can tell me, not only what you think, but also if you have something else to add or to correct, because it is clear that there are always concepts falling out of my hands and I would be glad to know them from your own hand, ans also you may have some doubts not answered yet regarding Oil Neem uses.Shall we begin then? Let’s go with the basics.

What is Neem Oil? Origin and properties

This oil, which is widely heard of, especially among those who are in favor of growing their plants in an organic way, owes its name to the tree from which it is extracted, in particular, from the Neem tree native of India, although today is grown in other countries with similar climates, ie tropical and subtropical.

In this regard, there are numerous countries in south America wherein we will find this tree, in fact, is also known on the other side of the Atlantic as Margosa or Lila India. Burma, in addition to India, as we said before, is another region in the world wherein you can see grow this type of tree that usually reaches 15 or 20 meters in height, although rarely can reach 35-40 meters .

When tree Neem blooms, their flowers are white beautiful colored and their fruit are slightly elongated as olive fruits, but somewhat longer (they can reach 28 mm long and 15 inches wide). Their color is yellowish and their flavor is a bit sweet, but it is not very pleasant in the mouth, at least not when it is in its purest state. So if you were wondering what does Neem oil taste like, I think I’ve just gave you an answer.

And, now that we have more data about Neem oil tree, we need to know where it comes from, even though I’ve just given you a clue. Indeed, this natural product is obtained from the fruits and seeds of that tree. Its most common use occurs in agriculture, but it is not the only one. We will also find Neem oil in natural and ayurvedic medicine, as well as in cosmetics or other sectors as we will see later.

But how is Neem oil extracted? There are two ways to do it mainly:

Pressing and grinding the seeds and leaves of this tree, a process that can be made cold or hot. It is said that this is the most effective method for the oil to retain all its properties, especially if it is made hot. This would be the purest oil you can obtain, loaded with the majority of active principles of interest to us.

-By solvent extraction (industrial organic solvents, even though you can use non toxic solvets such as ethanol) from seeds and fruits. In case of using toxic organic solvents, you can diminish the quality of this method compared to we have mentioned before and its use is normally restricted to soap production.

The raw and clean extraction leaves us a by-product that is known as Neem powder. At PevGrow, in fact, we have this product in powder form and its use is ideal for: organic farming as a basis of preventive control of insects proliferation responsible of pests in the cannabis crop. In addition, this product does not leave waste in treated crops, so its use is very safe.

Neem powder ECO

Returning to pure Neem oil, one of the ways to identify it is by its brown color on the one hand (the tonality can vary between the one that comes closer to yellow or orange and the one that has darker shades) and its strong aroma , on the other hand. In fact, experts say it smells like peanut and garlic. Curious mixture, right?

Although it is true that it is used in the country of origin within traditional medicine remedies, there are several studies that do not recommend their intake, in fact it is not a product for human consumption, but a phytosanitary product because it contains elements (active principles) in the composition that participate in its biocide action, helping those active principles to increase their activity.

In any case, what interests us most now is its use for our marijuana crops, and do not worry about its taste, since it will not affect the taste and quality of your final harvest if Neem is used correctly , respecting the security deadlines.

Yes, Neem oil is ideal to take care of your crop, mainly because it helps us to prevent and treat many cannabis pests, acting as a natural repellent in case of the pest has not occurred and as a natural insecticide in case we have not been able to control it before.

But what is really good is that its use carried out correctly does not affect people or animals, so it can be used both in indoor and outdoor cannabis crops, avoiding, as we said, the appearance or propagation of pests, especially insects such as whitefly, aphid, mealybugs, caterpillars, leafminers, thrips or red spider, among others, as well as can prevent the appearance of certain types of fungus which attack cannabis like mildew, botrytis or alternaria. It is recommended to blend pure neem oil with either potassium soap or sodium bicarbonate to promote fungicidal action.

As I said before, Neem oil has been used for centuries, mainly in agriculture, but in its country of origin is also used in traditional medicine and Ayurveda. And, although there are not many studies on the characteristics of this oil, its main properties are known: it is rich in Omega 3, 6 and 9. In particular, it is associated with antiseptic, antiparasitic and anthelmintic properties. In the same way, it is known that one of the main properties of the fruit from which this oil is extracted is that it is purgative.

But in addition, and here we speak of more scientific terms, which we find very interesting if we want to understand the benefits of its uses in our marihuana crop, is that neem contains more than 50 tetranortriterpenoids, being the best known and active Azadirachtin, which exerts an emetic action (induces vomiting and inhibits feeding) in the invasive insect.

Thus, Neem oil, unlike other industrial insecticides, does not directly kill insects or invaders that try to invade our crop, but prevents the insects from feeding, reducing the chances of their reproduction, so that finally or die or disappear. This prevents the pest from spreading, without forgetting that if they are trying to reach our crop already treated with neem oil, the mere smell of this oil will repel them. And all this being a product 100% natural without risk to human health. What else would you expect from this natural product?
