Lava-Lite+ - Natural Volcanic Stone Growing Media & Pot Topper
Best for: growers wanting a natural, multi-purpose volcanic stone media for pot topping, soil conditioning, or standalone hydro use.
Our thoughts
This is the base product in the wider Lava-Lite range, and it's a genuinely versatile one - decorative pot topper, soil conditioner, or hydro growing media, all from the same bag of volcanic stone. Priced sensibly enough that there's no reason not to keep a bag around.
Lava-Lite+ is a 100% natural, pH-neutral volcanic stone media, sold in a 1 litre pack. It's designed to hold up to 25% moisture while still draining freely, which cuts down on watering frequency without risking waterlogged roots, and its porous structure gives it a natural insulating effect that helps protect root systems from temperature extremes in both summer heat and winter frost.
It's a multi-purpose product: use it as a decorative top-dressing over pots, mix it into soil as a conditioner, or use it as a standalone growing medium in hydroponic systems. Being mineral rather than organic, it doesn't break down or need replacing season to season.
How it compares
Lava-Lite+ sits as the flexible, general-purpose option in a wider Lava-Lite family that includes dedicated blends like Hydro-Gro+ and Orchid-Gro+.
- More versatile than dedicated expanded clay pebbles, since it doubles as a decorative pot topper as well as a growing medium
- A natural alternative to synthetic pot toppers or bark mulch, with the added benefit of not decomposing
- Sits below the specialised Lava-Lite Hydro-Gro+ and Orchid-Gro+ blends if you want a medium tailored to one specific growing method rather than general use
A sensible, low-cost way to try volcanic stone media before committing to a larger specialist bag.
Usage guidance
As a pot topper
Spread a layer over the surface of the growing medium for a natural, decorative finish that also helps retain surface moisture.
As a soil conditioner
Mix into soil to improve aeration and drainage in the same way as Lava-Lite Soil-Restore+.
As a standalone hydro medium
Use directly as a growing medium in hydroponic systems where good drainage and moisture retention are both needed.

Our take
It's a small, low-cost bag, but it's genuinely useful across three different jobs rather than being a one-trick product. Handy to have around a grow space for topping pots or fixing minor drainage issues as they come up.
Does exactly what it should, day in, day out.
