The Right Growing Media For Your Indoor Crop

Which growing media will you prefer?

SOIL? COCO? Or PEBBLES?

We are not laying emphasis on one but rather we blog to inform you that you have a choice of several alternatives and you can always make your decision after your own personal research but will we provide the information you need about each of the media in this article.

Let start with this…

You need to know that the right media is very important

Yes!!! The right medium to plant your crops is very important, it will be worthy of note to tell you that this might be a very difficult task but at the long run it is very germane because at the end it determines the success of your crop germination.

For any growing media (Soil, Coco or Pebbles) you will like to consider for your hydroponic system, it is very germane for the growing media to have the ability to release and hold on to the positively charged element, because when growing hydroponically all important elements are added via a nutrient solution.

So in this article we are going to provide three different growing media and we will also tell you about the pros and cons of each of the three that will be mention.

Keep the following in mind!!!

First, Cation Exchange Capability, CEC in short; is an important factor to consider while you are making your decision on which media will suit your desired crop. Keep in mind that a medium with LOW CEC allows cation to be easily leached away in contrast, HIGH CEC will resister leachability of cations.

Next, the Air Filled Porosity (AFP), you need to know the volume of air space in such a growing media you are about to consider.

Finally, the Water Holding Capacity (WHC) of such a growing media is also important. This parameter will tell you the amount of water the growing media will hold and store. This will help your watering schedule at the long run. 

SOIL

 

Let’s start with soil, it will be considered the mother of all growing medium because before the inception of the modern day growing media soil has been the major growing medium used by dirt and organic farmers. Different crops need different soil requirements and it is important a farmer meets those requirement for good quality produce.

Sоіl Mіxеѕ:   

Thеѕе soil mіxеѕ start wіth the ѕоіl and thеn build uр a роwеrful and nutrient fіllеd mеdіа thаt will keep you growing and growing with оnlу thе bеѕt urban-grower hаѕ to offer. Whеthеr уоu'rе starting from seeds оr сuttіngѕ оur ѕеlесtіоn оf роttіng ѕоіlѕ wіll make уоu squirm wіth glее lіkе a wоrm іn the соmроѕt wіth all thе nutrіеntѕ thеѕе ѕоіlѕ соmе packed wіth great organic ѕоіl аmеndmеntѕ lіkе wоrm саѕtіngѕ, guаnоѕ, mycorrhizae bасtеrіа аnd more.

So, depending on the type of soil you are using, you will have different CEC, AFC and WHC.

COCO COIR/COCO FIBER

Coco Canna Professional Plus

Next is COCO COIR/FIBER, this growing media is made from coconut husks and this why it is called coco coir. Coco is a popular growing medium because of several reasons one of which is because it is one of the completely organic media available for hydroponic growing system.

It is also famous for its large oxygen and efficient water holding capacity which is cool enough for hydroponic growers.

More so, the related problem they face with other media with respect to this it also finds it easy to filters nutrients which plays a major role of preventing nutrient burn which at the long affects the quality of crop produce. Product like coco canna professional plus with awesome features that is flexible and farmer friendly and other related COCO product is available at urban-grower

Also the efficient water retention properties of coco made it possible to schedule the watering system effectively.

CLAY PEBBLES

Clay pebbles are made by heating clay at a temperature of about 2012F – 2192F in a rotatory kiln. The expansion clay is as a result of the heating process. The end product is a rough finished, highly porous medium that is effective at retaining moisture, trapping air, and oxygenating any nutrient solution that flows over it.

Clay pebbles can be used as a standalone media in a hydroponic system by hydroponic growers or as an amendment to coco or soil. Similar to perlite, clay pebbles have low water retention and act as a great media aerator while not heavily affecting moisture levels.

While there are many advantages to using a medium with low water holding capacity, note that under-watering can severely affect and/or kill your crop.

Clay pellets/pebbles allow уоur nutrіеnt-rісh water to flоw dіrесtlу dоwn to уоur рlаnt’ѕ rооtѕ so thаt thеу dоn’t hаvе tо ѕеаrсh fоr water, lіkе іn ѕоіl.
