How to Grow Marijuana & Hemp in Stonewool

Stonewool and Marijuana: A Magical Combination

Stonewool has its origins in the construction industry with its excellent properties as an insulator. However, curiosity mounted in the late 1960’s on its abilities to be used in the horticulture industry as a growing medium. After extensive testing and data collection, it was found with some modification to be an excellent growing media for a wide range of plants. This material is the direct result of melting basaltic rock and spinning it into thin, yet strong fibers into various shapes ideal for growing plants. Ever since then, the use of this material has certainly taken off and is one of the most popular growing media in the commercial horticulture industry.

Stonewool Production-

This media is very hardy and can last for several growing seasons. With this much hardiness, one may think that the creation of the media is complex. This is far from the truth as this material is the result of melting rock down. Once molten , the rock is cooled as it is spun into thin fibers. These fibers can then be shaped and pressed into the needed shapes for growing plants. The process is relatively simple. Although this is a man made substrate, the material is often regarded as a natural product as it originally came from molten rock.    

Using Stonewool for Hemp and Marijuana Production-

Stonewool has been the growing media of choice for hydroponic growers for decades. Ever since the beginning this growing medium has been excellent for use with all sorts of plants. It is because of this that the use of stonewool and marijuana became a very natural segway.  The overall modular nature of stonewool is that the root systems never have to be disturbed as each smaller cube can be easily placed into a larger stonewool grow cube to give larger growing area for roots as the plant matures and develops.

General Preparation-

Before use in the growing of marijuana or hemp, the stonewool needs to be prepared and stabilized. The growing media, because it comes from rock origins, the pH of the material is a neutral of 7.0. This is too alkaline for hemp to grow healthily. When the growing medium is too basic or alkaline, there is poor nutrient uptake, especially for the essential compounds of calcium and magnesium. In order to prepare the stonewool for hemp production, a proper soak in water for a full 24 hours in a nutrient solution to correct the pH to 4.5 and with an EC of 0.4-0.5. In order to ensure the grow media is the correct pH and EC, drenching the media in a 5.5 pH nutrient solution and testing the runoff.

Germination and Beginning Growth

Germinating seeds and growing from cuttings and clones can be very stressful for a plant and is a crucial point where the essential parts of a plant must establish themselves. It is important to have in place the proper growing media to start plants off on the right root. Smaller stonewool blocks are excellent for getting started especially for a grower new to hydroponics. This media allows for new seedlings and clones to readily root quickly and efficiently in a sanitary environment that can both support the plant at its current stage of life and beyond. Once the seeds have germinated where the clones or cuttings have become rooted then a grower can make the transition to larger blocks or slabs. This can be easily done by placing the cube into a pre-cut space on a larger slab or block. A grower can also customize the growing space for larger plants such as marijuana or hemp by getting grow slabs that are not pre-cut and cutting the holes themselves.

Established Growth and Mature Life Stages-

Once the plants have become mature and are more advanced in their life stages, the root system still needs room to grow. In order to support a larger more mature plant, they will need to be transplanted into larger cubes or slabs. With Stonewall, transplanting is very simple and easy to do. The smaller blocks or cubes can be placed into larger blocks and cubes in pre-cut spaces. Once these are placed into either a pre-cut slot or one that is cut customized to the plant's needs, the roots are able to grow out of the stonewool material into the new stonewool grow block or slab. The true benefit of using stonewool is the ability to easily upgrade a plant's growing space. This can be done without the stress of traditional transplanting as the roots are not disturbed. This contributes to plants that are less stressed and do not become stunted.

Stonewool is an excellent growing media for use in hydroponic systems as well as for the ever growing industry of hemp and marijuana production. As this industry grows, the need for support and better growing environments is a must. With the many benefits of Stonewool, the choice may be a simple one for many growers.

What are the different types of growing media?

Types of Grow Media

Stonewool - Coco Coir - Perlite - Vermiculite - Peat Moss - Grow Stones -Soil

- Stone wool - rock wool - mineral wool -

One of the most popular types of grow media is stonewool. Also known as mineral wool, rock stone wool is one of the best soil-less grow mediums a commercial grower can use as it is made from natural materials, typically does not contain impurities, offers excellent root zone aeration properties, and provides a perfectly balanced uptake of water and plant nutrients. As such, stonewool grow media is one of the most common types of grow media used in commercial greenhouses, indoor farms, and hydroponic operations.

Stonewool grow media comes in a wide range of shapes and sizes, such as- Grow Plugs and Cubes, Starter Blocks, Grow Blocks, Grow Slabs, and Multi-Flowering Slabs.

Check out the list below of other common types of grow media, mixes, and blends -

 

Coconut coir-

Coco coir is another popular type of grow media that is manufactured from shredded coconut husks. Coco coir is another common choice for commercial growers. This type of grow media  offers excellent absorption properties and can sometimes be reused or recycled.Coco coir grow media products typically come in the form of coco coir grow blocks, coco coir plugs, coco coir grow bags, loose coco coir chips, coco coir grow mats, and different types of coco coir potting mix blends.

Coir and Perlite blends:

Perlite coco coir mix- There are many growers that like to use loose coco coir blends, especially within hydroponics systems, that will add perlite to their mix to improve drainage properties with the commercial  hydro system. Typically, coco coir and perlite blended products contain different levels of coco coir with added perlite for enhanced drainage within soil and soil-less based grow operations.

Peat Moss Blends: Peat moss offers a unique ability to retain plant nutrients. As such, growers and farmers have been adding peat moss to soils and other grow media to assist with providing a nutrient-rich grow environment for plants and crops.

Perlite: By blending perlite into soils and other grow media, a grower can increase the drainage properties of their entire grow operation. Perlite does not absorb water and is used in both soil and soil-less grow operations to assist with aeration and drainage processes. Perlite can also be used as a stand alone grow media in different types of hydroponic systems for plants in early grow cycle stages.

Vermiculite- Vermiculite is another natural mineral that absorbs water and can expand when exposed to heat. Vermiculite is commonly mixed into soils as a soil amendment.

Soil & Potting Soil: Organic potting soil is the closest grow medium when compared to a plant being grown out in the natural world. Natural potting soils are typically nutrient rich, extremely absorbent, and much easier to use compared to hydroponic grow media.

Clay Pebbles, Grow Stones, and Other Growing Media- Clay pebbles and grow stones are some of the best options in terms of grow media. This type of hydroponic media is created from mineral deposits which offer excellent drainage and aeration properties when compared to other types of grow media. As clay pebbles and grow stones are a type of loose-fill grow media, they are perfect for easily transplanting plants and crops, and can assist with additional pest protection in your grow operation. Clay pebbles and grow stones are usually a bit more pricey when compared to the pricing of other types of grow media, however, this type of grow media can in most cases be re-used and not thrown out after one grow cycle.

Expanded Polystyrene- Polystyrene is another fairly common type of grow media. It is a bi-product made from polystyrene manufacturing processes. Polystyrene is perfect for increasing drainage and aeration properties, decreasing densities, and is extremely resilient to breaking down and decomposing.

Grow Media resins and foams- Urea Formaldehydes- This type of grow media is a type of manufactured resin or foam that offers high water retention properties and excellent aeration and drainage characteristics.

Other types of grow media, mixes, and blends- sand, sawdust, bark, bagasse, rice hulls, corn cobs, manure, peanut shells, pecan shells,pumice; cinders, and pea-gravel ...
