What is Hydroponics?

Hydroponics, for those who may not be aware, is the process of growing marijuana (or other plants) without actually having to use soil as the medium of growth. Instead, water is provided directly to the roots via different sorts of mediums. While this has been a method which has been in use since ancient times (think about the hanging gardens of Babylon) but has been something which is being adapted by a large number of people who grow weed indoors these days.

Hydroponics involves providing water directly to the roots, which ensures that the plants grow at a faster pace and even help increase the overall yield that they provide. Moreover, considering that this method of growing marijuana completely eliminates the usage of soil, it is actually something that can be used to grow weed even in places where the conditions of the soil isn’t favourable. In addition to that, this method of growth also allows you to grow more marijuana in less surface area. You need a hydroponic grow kit in order to grow marijuana indoors using hydroponics but this technique is really effective for modern-day growers.

What is Rockwool and How is it Beneficial for Growing Marijuana?

Before we answer your question of ‘Where can I find the best hydroponics store near me’, let us look at what Rockwool is and how is it useful for those who want to grow marijuana indoors

While most people know rockwool as an insulator which is made out of minerals and stones, it is essentially good for replacing soil as a medium of growth for the cannabis plants. Usually made out of a combination of basalt, which is a volcanic rock, and limestone, rockwool is great for insulation but also good for growing weed in it! The insulative properties of rockwool make it an ideal choice for growing the marijuana plant in, because it provides the root with enough space for drainage of water while also allowing them to grow well and absorb all the required amount of water. However, buyers need to be aware that they are not buying rockwool which is industrial-grade and are instead buying the plant-friendly rockwool!

Providing nutrients along with the water in rockwool cubes is great for weed because it ensures a better and faster growth as well as higher yields. If you were wondering where to buy rockwool cubes from to grow your marijuana in, here’s the answer:

Buy the Best Fertilizers for Rockwool Cubes in 2020:

When you grow your weed in rockwool cubes instead of growing it in the traditional way, i.e. with soil, you are basically putting your plants in a medium which does not have any nutrients in it! Unlike soil, Rockwool is simply an insulator and hence you will need to add nutrients to it. Simply put, you will need to add a nutrient solution to the water that you put in the rockwool cubes and it will hold it well near the roots. Here’s a closer look at the best nutrients and fertilizers available for Rockwool cubes in 2020:

#1. Advanced Nutrients 2320-14 Bud Candy Fertilizer, 1 Liter

Furthermore, providing this nutrient at an early stage would allow you to ensure that the plant grows up healthy and strong and provides a flourishing bud which is rich in flavour. 

While it is a nutrient that many growers tend to provide at the beginning of the growth cycle, one of the best things about it is that you can use it right till the harvest phase. However, you’ll need to flush your plant once before you harvest so take care of that!

In addition to this, there’s also the presence of fulvic acid and non-ionic surfactant which together form a multi-stage delivery matrix that helps the plants absorb the nutrients in a better manner. 

There’s a specially designed ‘balance-free ph perfect technology’ which ensures that the right ph levels are being provided to the plants. Growers who have used these nutrients to grow their plant have reported that they have managed to grow good-tasting marijuana and that the potency of the weed is pretty good as well. All three of them have to be used in conjunction with each other but the amount of each that you provide will vary from phase to phase of growth.

When used with a combination of the Bud Candy fertilizer, it provides optimum results as the plants that grow become strong and healthy, as well as tasty and offer a good flavour.

#1. Is hydroponics better than traditional soil-based growth?

This is a question that does not really have a definite answer. If you are someone who is very used to growing weed via traditional soil-based means then perhaps you should continue doing that. If you are the experimental types and want to try out hydroponic growth, you should totally give it a try and see if it is the method that suits you more. 

Personally, it is a matter of the grower’s choice and the resources that he or she has at their disposal. People who live in areas with easy access to soil and with large spaces to grow their weed in generally prefer growing their weed in soil. However, hydroponics is quickly becoming very popular among advanced modern-day growers, thanks to the quick growth and high returns that it offers.

#2. What are the advantages and disadvantages of hydroponic growth?

Among the advantages of hydroponic form of growth are faster growth of plants and getting better yields. Moreover, growing weed this way ensures that you can spray your water directly at the roots instead of pouring it on the soil from where it takes a longer time to reach the roots. This also ensures that nutrients are directly reaching the roots as well. These are some of the best reasons as to why people are choosing hydroponic growth over regular form of growing weed via soil.

Among the disadvantages of growing weed using they hydroponic method of growth is the fact that it does not carry any nutrients in itself like soil and you will need to provide nutrients to the plants by mixing it with water every time you water the plants. Moreover, providing water directly to the plants makes them susceptible to certain water-borne diseases.
