Terra Aquatica FlashClean 5l
Terra Aquatica FlashClean 5 litre is the professional-grade jerry can of the universal flushing solution and substrate regenerator — formerly known as GHE FloraKleen. FlashClean dissolves accumulated mineral salts, actively breaks the bonds between fertiliser residues and substrate particles, and makes locked-out nutrients available for plant uptake again. No acids, no enzymes, no mineral additives — safe at any growth stage without disrupting nutritional balance. Dosage 1.5 to 3 ml/L depending on plant maturity and application timing. At 3 ml/L, 5 litres produces over 1,650 litres of flushing solution. The jerry can offers the lowest cost-per-litre in the range and covers an entire season of professional substrate maintenance and system cleaning.
Terra Aquatica FlashClean 5L – Professional-grade supply for structural substrate maintenance
For professional growers managing multiple systems or large-scale operations, structural substrate maintenance is not a luxury but a necessity. The 5 litre jerry can of Terra Aquatica FlashClean — formerly GHE FloraKleen — delivers the lowest cost-per-litre in the Terra Aquatica range and sustained supply covering a full growing season, even with intensive maintenance across multiple rooms or continuous rotations.
Substrate regeneration at professional scale
FlashClean operates on a fundamentally different principle from other flushing products. It contains no acids, no enzymes and no mineral additives. Its proprietary technology breaks the bonds between mineral salts and substrate particles, making the released nutrients available again — for plant uptake or for removal during flushing.
- Salt dissolution: eliminates mineral deposits in substrate, lines and reservoirs.
- Nutrient release: makes previously locked-out elements available for root uptake once more.
- Microbial support: feeds beneficial microorganisms in organic and mixed media.
- Universal compatibility: hydroponics, coco, soil, clay pebbles, rockwool — indoor and outdoor.
Yield from the 5 litre jerry can
At a dosage of 3 ml/L, 5 litres of FlashClean produces over 1,650 litres of flushing solution. At the lower maintenance dosage of 1.5 ml/L, that figure exceeds 3,300 litres. Four applications, one product:
- Monthly maintenance: preventive flushing to avoid salt accumulation.
- After nutrient burn or lockout: immediate intervention — circulate 24 hours then replace with fresh solution.
- Before feed changes: clean slate before transitioning to FinalPart or a different program.
- Final flush: 2 days of FlashClean boosts sugar levels and enhances flavour — instead of 10 days of plain water flushing.
The investment for serious growers
The 5L jerry can delivers a substantially lower cost-per-litre compared to the 0.5L and 1L formats. Given that FlashClean is used at maximum bi-weekly frequency and the final flush requires only 2 days, a single jerry can covers months of intensive substrate maintenance. Pair with the 5L formats of FloraBloom, FloraGro and FloraMicro for a complete professional protocol.

How many litres of flushing solution does FlashClean 5L produce?
At a dosage of 3 ml per litre, 5 litres of FlashClean produces over 1,650 litres of flushing solution. At the lower maintenance dosage of 1.5 ml/L, that rises to over 3,300 litres. A single jerry can covers an entire growing season.
Is the 5 litre format more cost-effective?

Can I use FlashClean to clean my hydro system between cycles?
Absolutely. FlashClean is excellent for cleaning your entire hydroponic system between cycles. Circulate a 3 ml/L solution through the empty system for 24 hours to remove salt deposits from lines, pumps and reservoirs. Rinse with clean water and start your new cycle with a pristine system.
How long does FlashClean keep after opening?
FlashClean is a stable mineral solution that retains its effectiveness long after opening. Store the jerry can in a cool, dark location with the cap securely closed. The product contains no enzymes or biological components that can degrade, ensuring excellent shelf life.
