Tropic 70/30 Cocomix - Premium Coco/Perlite Growing Medium

Premium results without the premium price tag. Tropic 70/30 Cocomix is a professionally balanced coco coir and perlite blend, giving you the aeration and drainage of leading hydroponic brands at a fraction of the cost.

Why Growers Choose Tropic 70/30 Cocomix

70% Buffered Coco Coir / 30% Perlite
The industry-standard ratio for a reason: coco coir holds water and nutrients close to the root zone, while perlite keeps the structure open and oxygenated, protecting against waterlogging and root rot.

Buffered and Ready to Use
Pre-buffered to strip excess salts, Tropic 70/30 Cocomix is a genuinely low-EC "blank canvas" straight from the bag — no soaking, no pre-treatment, no guessing what's already in there before you start feeding.

Superior Aeration, Faster Drainage
The 30% perlite content dramatically increases oxygen flow to the root zone and speeds up drainage, making it ideal for high-frequency feeding, fertigation, and drip systems.

Premium Mixed Substrate
A clean, light, and fibrous structure that resists compaction throughout the full grow cycle, so it stays airy and effective from first watering to last.

📦 Please Note: Sample, 1L, 5L, 10L, and 20L sizes are carefully decanted from original manufacturer packaging into secure, unbranded packaging to offer flexible quantities for every project size. 50L options are supplied in the original sealed manufacturer bag.

The Civilian Pitch: A Houseplant & Aroid Collector Favourite

Gnat-Proof By Design. Fungus gnats breed in decaying organic matter, exactly what standard peat compost is full of. Coco coir is sterile and inert — no food source, no gnats.

Genuinely Hard To Overwater. The 30% perlite content forcibly holds oxygen pockets even when the substrate is fully saturated, which is exactly what protects roots from the chronic overwatering that kills more casual houseplants than neglect ever does.

A Professional Blank Canvas. The buffered, low-EC base means zero risk of fertiliser burn on a freshly repotted rare plant, and total precision over what you feed it, drop by drop.

Hero Plants: Variegated Monstera (Albo, Thai Constellation), rare Philodendron (Pink Princess, Verrucosum), Alocasia (Frydek, Polly, Black Velvet), Hoya, Syngonium, Scindapsus, and Anthuriums — all natural epiphytes that demand aggressive root aeration. Equally suited to the "Drama Queens" — Calathea, Maranta, and Stromanthe — which need constant, even moisture without ever sitting wet, and to high-value propagation: unrooted nodes, wet sticks, and fresh cuttings that need sterile, oxygenated moisture to root without rotting. Grab a Sample or 1L before committing to a full 50L bag if you're only repotting one or two plants.

Before you buy: this is a professional sterile base with no pre-loaded fertiliser, so a liquid feed is essential from day one. Intense Nutrients Coco A&B is a budget-friendly, reliable two-part feed that suits Tropic's own value-for-money positioning perfectly.
