LAVA‑LITE HYDRO‑GRO+ Hydroponic Growing Media (The Light Blue One)

LAVA-LITE HYDRO-GRO+ is a premium volcanic hydroponic growing media and natural LECA alternative, giving you complete control over your hydroponic or aquaponics substrate setup.

Its ultra-porous structure encourages strong root distribution, supports beneficial microbe colonisation and provides the ideal balance of drainability, moisture retention and gas exchange in the root zone. Because it is 100% natural, pH-neutral and chemically inert, HYDRO-GRO+ allows growers full control over nutrient feeds, fertilisers and additives without interference from the substrate.

It significantly reduces the risk of soil-borne diseases and supports healthier, more vigorous plant growth from seedling through to harvest.

⭐ Perfect For

• Hydroponic systems (DWC, NFT, drip, ebb & flow)
• Aquaponics setups (safe for fish)
• Semi-hydro houseplants (aroids, hoyas, alocasias)
• Cutting propagation & rooting stems
• Soil-free vegetable growing (lettuce, herbs, peppers)
• Grow troughs, raised beds & planters
• Replacing LECA with a more porous, microbe-friendly media
• Growers wanting full control over nutrients & feeding regimes

⭐ Key Benefits

• 100% natural volcanic media — pH-neutral & chemically inert
• Porous structure supports beneficial bacteria & microbe colonisation
• Soft edges protect delicate roots and encourage new growth
• Ideal balance of drainage, moisture retention & gas exchange
• Reduces soil-borne diseases — perfect for soil-free growing
• Reusable & eco-friendly — supports high crop cycles
• Complete nutrient control — inert media won't affect feeding regimes
• Suitable for seeds, seedlings & cuttings

⭐ How To Use

If using seeds, fill your hydroponic container completely with HYDRO-GRO+. If using seedlings or cuttings, fill the container up to the depth of the root system. Gently pat down the media to create an even surface and ensure full contact with the container edges. Push seeds into the media to a depth of around 3 inches, or hold seedlings/cuttings in place and fill the rest of the container. Rinse before use to remove fines and prevent filter clogging. Add nutrient solution or water to your hydroponic reservoir and maintain as normal.

⭐ FAQs

What is LAVA-LITE HYDRO-GRO+? It is a natural volcanic hydroponic media designed to provide excellent aeration, drainage and moisture control for hydroponics, aquaponics and semi-hydro houseplants.

Is HYDRO-GRO+ safe for fish and aquatic systems? Yes — it is chemically inert, pH-neutral and completely non-toxic. It is safe for aquaponics, fish, plants and beneficial bacteria.

Can HYDRO-GRO+ replace LECA? Absolutely — HYDRO-GRO+ offers superior porosity, faster bacterial colonisation and better moisture balance compared to traditional clay pebbles.

Does HYDRO-GRO+ help prevent root rot? Yes — its free-draining structure and controlled moisture retention help prevent waterlogging and support oxygen-rich root zones.

Can I use HYDRO-GRO+ for houseplants? Definitely — it is ideal for semi-hydro setups, aroids, hoyas, alocasias and plants that prefer consistent moisture without sitting in water.

Is HYDRO-GRO+ suitable for propagation? Yes — its moisture-balanced structure supports rooting cuttings and growing new plants.

Does HYDRO-GRO+ affect nutrient levels? No — it is completely inert and will not alter feeding regimes, making nutrient control easy and predictable.

Do I need to rinse HYDRO-GRO+ before use? Yes — rinse thoroughly to remove natural volcanic dust and prevent filter clogging.

Does HYDRO-GRO+ degrade over time? No — it is long-lasting, reusable and maintains its structure across multiple growing cycles.
