FlashClean 5 Liters Terra Aquatica is a salt and residue cleaner designed to restore growing media in indoor cultivation. It optimizes nutrient absorption, prevents blockages, and prepares roots for a clean maturation, compatible with soil, coco, and hydroponics.

FlashClean 5 Liters Terra Aquatica (historically known as FloraKleen) acts as a flushing agent that dissolves excess salts and residues of cannabis fertilizers accumulated in substrates and systems.
This reset effect rebalances the nutrient solution and unlocks roots, allowing plants to once again assimilate essential elements normally.
It works both in intermediate stages to correct buildups and in the final stretch, where a controlled flush promotes clearer maturation and drying with fewer impurities.
The formulation is compatible with cannabis fertilizer programs and intensive watering schedules, maintaining microbial activity and stabilizing the medium.
The 5 L format is enough for several batches in grow tents and professional rooms, and fits into maintenance routines alongside indoor growing accessories such as EC/pH meters and recirculation tanks.
Available at Hydroponics Blanes, Grow Shop in Spain and Trusted Grow Shop with discreet shipping and technical support.
In indoor growing environments with frequent watering, salt buildup is a real risk that leads to nutrient lockouts, dull leaves, and loss of vigor. FlashClean 5 Liters Terra Aquatica reduces this stress: it removes residues in soil, opens pores in coco, and cleans circuits in hydroponics, stabilizing the rhizosphere without harming roots. Integrating periodic flushes improves response to the feeding schedule and helps the cannabis fertilizer plan achieve floral density and consistency goals.
• Remove accumulated salts and residues of cannabis fertilizers in substrates and systems.
• Prevent lockouts and restore NPK and micronutrient uptake.
• Sanitize the system between solution changes in hydroponics and during nutritional transition stages.
• Flush roots before harvest for a cleaner profile and more even maturation.
• Stabilize parameters (EC/pH) when heavy watering has saturated the medium.
Considered a management tool, FlashClean 5 Liters Terra Aquatica provides operational control: it allows you to correct deviations without replanting, extends substrate lifespan, and helps keep lines and drippers clearer. In rotation rooms, it enables recipe changes between stages without carrying over excesses from the previous program. Ideal with well-calibrated meters and a watering protocol that includes sufficient drainage for effective flushing.
Medium compatibility: soil, coco, and hydroponics.
In hydroponics (between solutions):
• Add 1.5–3 ml/L of water when renewing the tank.
• Use a low dose for young or delicate plants; high dose for robust or pre-harvest plants.
• Let circulate for 24–48 h before reintroducing fertilizers.
Pre-harvest flush (final flush):
• Empty the tank or discard old solution.
• Fill with fresh water and add 3 ml/L of FlashClean.
• Maintain for 1–2 days; then harvest or switch to clean water if the plan requires.
In soil and soilless substrates:
• Every 15 days, prepare fresh water with 1.5–3 ml/L and water until visible runoff is obtained.
• Repeat according to EC reading of the runoff and crop behavior.
Best practices:
• Measure EC/pH of irrigation and runoff to confirm flushing effectiveness.
• Ensure proper substrate ventilation and temperature to avoid root anoxia.
• After the reset, gradually reintroduce the feeding program to avoid EC spikes.
The price of FlashClean 5 Liters Terra Aquatica is offset by its performance in multiple flushes and by reducing issues from salt buildup. Cost-effective format for medium and large-scale rooms. Check offers and packs at Hydroponics Blanes.
