Dr Greenthumbs TurboDirt Living Soil

TurboDirt by Dr Greenthumbs is a premium, water-only living soil, ready to use straight out of the bag, no composting, mixing, or “cooking” required. Crafted in Australia from 100% organic ingredients including worm castings, compost, peat moss, perlite, and zeolite, TurboDirt establishes a nutrient-dense, microbially rich foundation for vigorous plant growth. Pre-loaded with all essential nutrients, it supports crops for up to 9–10 weeks without additional feeding, promoting strong roots, lush foliage, and flavourful harvests. By fostering a thriving microbial ecosystem in the rhizosphere, TurboDirt enhances nutrient conversion and uptake, leading to healthier plants and higher-quality yields. Its well-balanced structure provides excellent drainage, aeration, and moisture retention, ensuring plants thrive across the entire growth cycle. Designed for both hobby growers and professionals, TurboDirt takes the complexity out of soil preparation, making water-only gardening simple and reliable. Because it’s organic and Australian-made, TurboDirt supports local production while delivering sustainable, environmentally responsible cultivation. Whether used in pots, beds, or larger-scale grows, it provides growers with a ready-to-use super soil that maximises flavour, aroma, and crop resilience.

Green Planet

Green Planet Hydro Clay

Green Planet Expanded Clay is a professional-grade, 100% natural growing medium created from thermally expanded clay. Its lightweight, porous structure provides exceptional aeration and drainage, preventing waterlogging while maintaining the perfect balance of air and moisture in the root zone. This makes it an ideal choice for hydroponic, aquaponic, and soil-based systems, as well as for use in propagation or as a stabilising medium for larger plants. Each clay pellet is inert, pH-neutral, and sterile, ensuring that your nutrient solutions remain stable and uncontaminated. The unique honeycomb structure encourages strong root development, improves nutrient uptake, and promotes beneficial microbial activity within the root zone. Because the pellets are non-degradable, they can be washed, sterilised, and reused across multiple crop cycles, making them both cost-effective and environmentally responsible. Expanded Clay also doubles as an excellent top-dressing material to reduce evaporation and discourage pests such as fungus gnats. With its combination of durability, reusability, and reliable performance, Green Planet Expanded Clay is a versatile solution for growers seeking a clean, consistent, and aeration-focused medium.

W2G

W2G Coco Brick

The W2G Coco Brick is a premium compressed coco coir medium designed for professional horticulture. Manufactured to RHP standards and buffered with calcium and magnesium, it provides a stable and reliable substrate for seedlings, cuttings, and mature plants across hydroponics, pots, and mixed media systems. Each 5 kg brick expands to approximately 60 litres of high‑quality medium when hydrated. Enriched with Trichoderma fungi for improved root health and resistance to soil‑borne pathogens, W2G Coco delivers superior air‑fill porosity and free‑draining structure. This balance of aeration and moisture retention supports vigorous root development, consistent nutrient uptake, and strong plant performance. Naturally renewable and long‑lasting, it offers both growers and the environment a sustainable alternative to traditional substrates.

Nutrifield

Nutrifield Coco Perlite

Nutrifield Coco Perlite is a premium, ready-to-use growing medium blended at 70% coconut coir and 30% perlite to deliver the ideal balance of water retention, drainage, and root-zone oxygenation. The coco fraction is thoroughly washed, pre-buffered with calcium, and pH-stabilised for low-salt, consistent performance straight from the bag, helping to prevent common early-stage lockouts. The 30% perlite increases porosity and airflow through the media, supporting rapid root development, faster growth, and reliable nutrient uptake under frequent fertigation. This blend suits a wide range of systems, hydroponic drip-to-waste, recirculating coco, container gardening, and propagation, and is an excellent upgrade from straight potting mixes where precise irrigation and oxygen availability are needed. Quality controls on the coco ensure a clean, uniform substrate with a stable cation balance so calcium and magnesium remain available from day one. The blend is lightweight and easy to handle, allowing quick filling of pots and beds with minimal compaction while maintaining structure over the crop cycle. Made from renewable coconut husk and inert perlite, Nutrifield Coco Perlite delivers professional-grade performance with a lower environmental footprint. It’s the dependable base media for growers who want consistent results across veg, bloom, and repeat cycles.

Green Planet

Green Planet Coco

Green Planet Coco Coir is a professional-grade, ready-to-use growing medium made entirely from renewable coconut husk fibres. Processed in a world-leading ISO 9001 certified facility, this coir undergoes fresh water retting to ensure exceptional purity and consistency. Each batch is RHP-certified (028DS15) and fully compliant with EN 12580 European standards, guaranteeing a product that is contaminant-free, safe, and reliable for growers of all levels. Coco coir is prized for its ability to hold water while maintaining superb aeration, creating the perfect environment for healthy root growth and efficient nutrient absorption. Unlike many unprocessed coir products, Green Planet’s coir is pre-buffered to neutralise excess sodium and potassium, ensuring stable calcium and magnesium uptake from day one. This results in stronger root systems, faster vegetative growth, and improved plant resilience throughout the crop cycle. With its clean, pH-neutral profile and natural structure, Green Planet Coco Coir is highly versatile, whether used on its own, blended with perlite or soil, or as part of hydroponic systems. Its lightweight, low-dust composition makes it easy to handle and apply, while its renewable sourcing provides an eco-conscious solution for growers who value sustainability as well as performance.
