If you grow houseplants in semi-hydro setups like LECA, Pon, or Stratum, you know the biggest fear is the dreaded "reservoir rot." One day your Alocasia is thriving, and the next, the water smells off and the roots are turning to mush. Flairform Pythoff is the industrial-strength solution designed to keep your reservoir sterile and your roots pearly white.
Root rot (Pythium) thrives in warm, stagnant water—exactly the environment often found in indoor reservoirs. Pythoff acts as a "reset button" for your water, using an advanced formulation of chlorine compounds to sterilise the solution and prevent disease from taking hold.
Keeps Reservoirs Clean: It acts as a sterilising agent, keeping your nutrient solution free of pathogens and preventing the slime and smell often associated with standing water.
Stops the Rot: It is extremely effective at preventing Pythium (root rot) and can even treat the disease if you catch those browning roots in the early stages.
Prevents "Root Browning": We all want those Instagram-ready white roots. Regular use helps prevent root browning, keeping the root system looking as healthy as the foliage.
Non-Systemic Safety: The formula is non-systemic, meaning the plant does not absorb the chemicals into its tissue. It simply keeps the root zone safe.
This isn't a gimmick; it’s a formula backed by decades of water treatment experience. Commercial growers have used it to save crops of over 50,000 plants from failure. If it can save a commercial farm, it can save your Variegated Alocasia.
In the houseplant world, we love our "beneficials" (like Great White or Rooting Powder), but Pythoff creates a sterile zone.
Do NOT use with Beneficial Bacteria: Pythoff will kill the good fungi along with the bad. Use this for sterile setups, not organic/living soil styles.
Do NOT use with Hydrogen Peroxide: It is not compatible.
Dilute: Pre-dilute with water before adding to your watering can or reservoir.
Add: Pour into your nutrient solution. It is safe to use from the moment you root a cutting all the way to a mature plant.
