Can you use hydroponic nutrients in soil? (2021 guide)

Can you use hydroponic nutrients in soil?

Every grower has probably pondered this at some point.

The short answer is: Yes, you can use hydroponic nutrients in soil (but it’s obviously not ideal).

If you’re a grower who’s keen to learn more, read on for the slightly longer and more detailed explanation…

Using hydroponic nutes in soil

They might not be the most appropriate additive, but hydroponic nutrients can be used in soil.

Here’s why…

Nutrients typically contain three essential elements to help plants grow:

  • Nitrogen(N)
  • Phosphorus(P)
  • Potassium(K)

You’ll often see these referred to as N-P-K on the nutrient manufacturer’s label.

Usually, nutrients will also contain other important elements that contribute towards the plant lifecycle – allowing it to grow and flourish.

Go steady and don’t over feed

Most soil mixes already contain quite a few nutrients. For the first few weeks of growth, adding just plain water is more than sufficient.

During this vegetative stage, your grow will build up a root base that allows it to develop bigger branches and leaves – so you enjoy a bumper yield.

The bigger the roots, the better your grow.

When it comes to feeding, we recommend using Guanokalong Powder for accelerated root development or Roots Excelurator Gold by House and Garden nutrients as these are designed specifically for soil.

But that doesn’t mean you can’t use hydroponic nutrients in soil if you have some spare.

It’s not ideal, but it can be done – if you’re cautious and use a well-diluted solution.

Getting the correct dosage may prove tricky.

You also need to avoid the risks of overfeeding.

But using a mixture with every other watering should not prove too problematic.

Aim for a Ph level between 6 and 7 and you should be okay – most nutes are soluble in this range.

If you want to avoid the risk of damaging a soil grow, opt for the proven qualities of Plagron Bat Guano, a natural soil fertiliser that encourages healthy growth and sweet tastes.

Ecothrive Charge – a soil conditioner bursting with beneficial bacteria for rapid growth and massive yields – will also do a similar job for under £6.

Above all else, remember that planting a home grow is meant to be fun. Play around, learn and enjoy the experience!
