Coconut Brick 650 g. 10 Liters is a dehydrated block of coconut fiber that, when hydrated, yields up to ≈10 L of spongy substrate. Designed for indoor cultivation, it offers great aeration, fast drainage, and precise nutritional management within substrates for cannabis. Available at Hydroponics Blanes, online grow shop with discreet shipping.

The compact format of Coconut Brick 650 g. 10 Liters simplifies storage and transport, and is hydrated with clean water to expand to a practical working volume.
The coconut's lignocellulosic matrix stands out for its homogeneous distribution of air and water, low initial salinity, and high cation exchange capacity, resulting in active roots and efficient nutrient absorption.
During manufacturing, washing and fiber selection processes are applied to reduce fines, minimize root suffocation, and maintain a stable structure cycle after cycle.
As an unfertilized medium, it allows you to design a custom liquid fertilization plan, with control of EC and pH from the first watering. It works as the main substrate in pots, on drip tables, or combined with perlite/clay pebbles to customize retention and drainage.
A versatile option for grow tents, rooms, and indoor cultivation projects seeking uniformity and cleanliness in the root zone.
In indoor cultivation scenarios, coconut buffers humidity variations without compacting, promotes rapid vegetative growth, and an orderly transition to flowering. The porosity supports a continuous flow of oxygen around the root system, compatible with pulse irrigation and reliable EC/pH reading in the drainage. Ideal for LED or HPS, fabric or plastic pots, and automation with drippers.
It serves as a main medium for complete cycles, as an ecological substitute for mineral substrates in drip/recirculation systems, and as an aerating component in soil mixes. It is especially interesting in substrates for cannabis where oxygenation, quick response to watering, and fine nutritional control through liquid solutions are valued.
Composition: vegetable coconut fiber sieved and washed. Outstanding properties: great aeration, high capillarity, low initial conductivity, and homogeneous structure. Indicative yield: one 650 g brick generates up to ≈10 L of hydrated substrate, enough for several small pots or one medium pot. Compatible with organic or mineral plans and with additives such as Ca/Mg when working with soft or osmosis water.
Hydration: place the block in a container and add 3–5 L of water (adjusted to pH 5.8–6.0); wait for full expansion and crumble by hand until spongy texture.
Conditioning: drain excess and, if preferred, perform a pre-watering with a light solution and addition of Ca/Mg to stabilize the exchange complex.
Pot filling: pour without over-compacting; just level with the palm to maintain porosity.
Watering and nutrition: start with low EC and gradually increase according to phase; aim for 10–20 % drainage per event to flush salts and measure return.
Optional improvements: add 10–30 % perlite if faster drying is desired; place a layer of clay pebbles to maximize drainage in deep containers.
Reuse: remove roots, wash, rehydrate, and re-balance pH before the next cycle.
The 650 g presentation with ≈10 L yield offers a very competitive volume/cost ratio for modular setups and replacements. Check availability and offers at Hydroponics Blanes, with specialized technical support and discreet shipping from a recognized online grow shop known as a Trusted Grow Shop.
