Organic Hydroponics: How To Organically Grow Soilless Plants

Nov 20

One of the hot debates in the field of agriculture has been that of organic hydroponics. Are there ways to cultivate organically without soil?

You may be thinking" of course it is - I can just feed my hydro plants an organic nutritional solution isn't it? It was not feasible in the past because organic nutrients were too dense and blocked the systems.

However, in recent times organic plant nutrition has developed to the point that it is not a concern. There are many organic formulas that claim to be suitable for hydroponics.

Yet, many growers claim that organic growing will never actually be possible through a hydroponics-based system.

This debate will be explored in depth, and then take the time to look at the arguments from both sides of the fence, to put this debate to rest.

Then, we'll give you our recommendations on how you should take the next step if you're thinking of giving this method in the horticulture field! Let's start with some definitions.

What is Organic Hydroponics?

Organic hydroponics is the combination of two cultivation techniques that are highly appreciated within their fields of study: hydroponic and organic.

We'll quickly go over each of them and provide background information for those unfamiliar with horticulture.

What is Organic Growing?

Different people have different notions of what constitutes organic, which is where the debate surrounding organic hydroculture comes into play.

Organic farming is merely a cultivating method that does not include synthetic additives or genetic engineering.

This means that there are no synthetic plant nutrients, and also no synthetic pesticides. This is a much tougher way to grow, as it means you have to be able to have your integrated pest control method in place to avoid the need to apply pesticides or fungicides in the garden or grow room.

Organic plant nutrients are not as easy to digest, since they are absorbed slower. This means it takes longer for nutrient deficiency to show itself, and takes longer to correct as well. Natural cultivation is the preferred method of cultivation by many growers.

The Benefits of Organic Growing

The greatest advantages of organic farming can all be summarized as "cleaner crops". It's no surprise that using only natural, organic fertilizers produced a more natural, healthier tasting and smelling crop.

Synthetic fertilizers can impede the plant's natural flavonoids or terpenes, which make it taste and smell. This is a problem that can be prevented by sticking with organic fertilizers.

Organic growing is, naturally, healthier and safer for both the environment and those who consume your plants.

Synthetic pesticides, in some instances, may leave behind residuals in your plant that eventually you consume.

What is Hydroponics?

This is a far simple concept to understand It's an approach to cultivation that doesn't need soil.

Instead, you can utilize inert media such as coco, rock wool, and clay pebbles to hold the plants. Your plants will get a concentrated nutrient solution at their root, based on the system you choose to use.

DWC systems place the roots of the plant in nutrient solution at all times, while an ebb and flow system will periodically fill them with nutrient solutions before draining them off on the cycle.

The hydroponic drip system is an additional alternative. They feed plants with small emitters. They work very similarly to drip irrigation. Aeroponics is another type that is worthy of mentioning. It's actually its own subset in cultivation.


Although hydroponics isn't for all, it is very useful. One is the ability to boost plant growth by altering the number of nutrients that are taken in and their concentration.

The roots of plants can absorb nutrients more effectively due to their oxygenation, usually by using an airstone and pump. This allows them to grow to their full potential.
