How does HYDRO-GRO+ work?

Suitable for: Hydroponics/aquaponics/cutting propagation

Hydroponic growing requires a stable controlled environment, which can often be difficult to manage, but with HYDRO-GRO+ you have complete control. Its composition encourages root distribution and strength and as a pH neutral, 100% natural, chemically inert media, it provides the perfect base for full control of the addition of feeds, nutrients and any introduced fertilisers that form your hydroponic system.

Additionally to this, HYDRO-GRO+ soil-less growth reduces the associated issues of soil borne diseases, whilst encouraging beneficial bacteria or microbe colonisation. The product can be reused, offering a high crop cycle with complete control, from seedling through to harvest.

Choosing HYDRO-GRO+ is an absolute must to ensure you have complete control over your hydroponic or aquaponic system.

How to use HYDRO-GRO+

How to use HYDRO-GRO+

Step 1
If using a seed, fill your hydroponic container completely with the product. If you are using a seedling or cutting, fill up to the depth of your seedling/cutting. For example, if your seedling is four inches long, leave a four inch gap.

Step 2
Gently pat down the product to make as even a surface as possible, pushing it fully to the edge of your pot/container.

Step 3
Using your finger, push your seed into the product to a depth of roughly 3 inches. If using a seedling/cutting, hold it in place and fill in the rest of the way up to the top of the container with product.


Can LAVA-LITE HYDRO-GRO+ be used on vegetable plants?

Of course. HYDRO-GRO+ works well as a soilless hydroponic grow media for certain vegetables.

Is HYDRO-GRO+ suitable for use with cut flowers in a vase?

Yes. HYDRO-GRO+ can be used for cutting propagation.

As HYDRO-GRO+ is a volcanic stone, will it harm the smaller roots?

No. HYDRO-GRO+ has smoother edges that will not harm the delicate smaller roots, thus helping new growth.
