Ten pre-measured dry-powder formulations covering the full cycle — vegetative, bloom, root support and finish. Each satchel makes 8 litres. Nothing to measure, nothing to refrigerate.
Supplies an additional carbon source for experimental setups, helping plants maintain continuous metabolic activity around the clock. Mix into the reservoir last.
The essential mineral foundation for vegetative growth — supports vigorous root development, dense foliage and strong structural growth.
The companion to Grow A. Together they provide a balanced profile supporting development and structure from seedling to maturity.
Shifts nutrition toward reproductive growth, supporting larger blooms and productive harvests.
Works alongside Bloom A to help flowering and fruiting plants reach their full potential with balanced late-stage nutrition.
A root-support formula designed to optimise the environment surrounding root systems and keep plants vigorous through the cycle.
Supports the production of aromatic compounds for flavour-focused harvests.
A targeted transition formula to help plants move efficiently from vegetative growth into flowering.
A late-stage enhancer designed to support plants during final production when every gram matters.
A finishing formula intended to clear and refresh hydroponic systems before the final cut.
In concentrated dry form, calcium and phosphorus bind on contact into calcium sulfate — gypsum — an insoluble rock that suffocates roots. It cannot be undone by shaking the bag.
Our factory-sealed satchels keep those elements isolated until they hit the water line, where dilution keeps them separate and fully bio-available. That is why A and B are never combined, and why the acetate ships on its own.
Calcium meets sulfur and phosphate in the pouch. Any humidity triggers precipitation lock and forms a chalky gypsum crust.
The crust sinks to the bottom of the reservoir as sludge the roots can never absorb.
Each part stays factory-sealed and inert until it is diluted into eight litres of water.
Water molecules keep the minerals apart and available. No clumping, no lockout, no guesswork.
One of every DarkGrow premium supplement in a single package, for growers who want maximum flexibility across the whole crop cycle.
Four complete crop cycles. Two hundred satchels covering nutrients and supplements for a full year of continuous growing.
Injection-moulded lid with twenty-one propagation sites plus centre collar. Swaps onto the same 10 L bucket for cuttings and microgreens.
Nutrient satchels, carbon supplement satchels, quick-start guide, mixing instructions and a growing schedule.
Order matters. A and B go in separately, the acetate goes in last, and nothing gets pre-mixed dry.
