General Hydroponics FloraKleen - 2.5gal

System and Media Cleaner for Fertilizer Salt and Mineral Buildup, 2.5gal

Fertilizer salts and mineral residue accumulate in hydroponic tubing, reservoirs, and growing media with every feeding cycle, and left alone that buildup can block irrigation lines and interfere with nutrient uptake at the root zone. General Hydroponics FloraKleen is a system cleaner formulated to remove that fertilizer salt and mineral residue from hydroponic tubing, reservoirs, growing media, and irrigation lines.

The 2.5gal size suits growers resetting a moderate number of plants or rooms who want fewer refills than a 1gal bottle.

Key Features & Benefits

• Salt and mineral removal — clears fertilizer salt and mineral residue from tubing, reservoirs, and media.
• System-wide cleaning — reaches irrigation lines and reservoirs in addition to the growing medium itself.
• Between-cycle use — designed to be run between feeding cycles or at harvest to reset the system.
• Any-medium compatibility — works across the hydroponic and growing media types found in most systems.

Who Should Use FloraKleen

Growers who feed on a recurring cycle and want to reset their system between crops, or who are flushing before harvest, are the fit for FloraKleen. It is used as a between-cycle maintenance step rather than an everyday feeding product.

Frequently Asked Questions

What does FloraKleen do?

FloraKleen is a system cleaner formulated to remove fertilizer salt and mineral residue from hydroponic tubing, reservoirs, growing media, and irrigation lines. It is used between feeding cycles rather than as part of a regular nutrient program.

When should I use FloraKleen?

Most growers run it between feeding cycles or at harvest, before starting a new crop in the same system. Follow the label's dilution rate and soak or flush duration for your setup.

Will FloraKleen harm my plants if I run it with them still in the system?

FloraKleen is formulated for use between crops or as a pre-harvest flush rather than as an in-season feeding additive, so follow the label's guidance on timing relative to your plants. Using it outside that intended window is not what the product is formulated for.

Does FloraKleen replace regular reservoir cleaning?

No, it addresses fertilizer salt and mineral buildup specifically; general reservoir and equipment cleaning is still a separate maintenance step. Use FloraKleen as part of, not a replacement for, routine system upkeep.

Which parts of my system does FloraKleen clean?

It is formulated to clear residue from tubing, reservoirs, growing media, and irrigation lines rather than one component alone. Running it through the full system is what resets buildup across all of those parts at once.
