Clearex Rinsing Solution, 1 qt

Clearex is a salt leaching and pre-harvest flushing solution designed to correct and remove the buildup of nutrient salt deposits in soils or soilless grow media.

It's Clear Growing from Here

Use Clearex to correct the most common cause of crop failure - the buildup of nutrient salt deposits in soils or soilless grow media. High salt concentrations in media can cause the shrinkage and death of plant cells due to the excess draw of water through cell walls, and eventually lead to the irreversible wilting of plant leaves and stems. Periodic flushs with Clearex will remove excess nutrient salts and safely leach them from your crops media.

Clearex can also be used at the end of a crop’s growth cycle to trigger the last reproductive stage of the plant forcing it to process and assimilate internally stored nutrients. Pre-harvest treatments with Clearex can enhance flavors and increase yields in fruits, vegetables, and culinary herbs encouraging plants to process these excess nutrients.


  • Prevents irreversible wilting.
  • Isotonic to gently leach salt safely without harming root hairs.
  • Triggers last reproductive stage of plant cycle.
  • Enhances flavor and yields.


Q: Should I use Clearex by itself or with a normal nutrient solution?
A: Clearex is meant to assist in leaching and flushing minerals from within the grow medium and should be mixed with fresh plain water.

Q: Do I need to pH adjust a Clearex solution?
A: Yes, always adjust the pH before using Clearex to flush any medium.

Q: How soon after using Clearex can I begin applying nutrients again? 
A: After using Clearex to flush the medium resume regular feeding with your next scheduled watering to avoid nutrient deficiency or imbalance.

Q: Previous Clearex labels listed sucrose and glucose but now only lists citric acid. Has the formula changed?
A: The formula has not been altered in any way. Only the label has been changed. Due to registration regulations, we were advised to remove sucrose and glucose from the guaranteed minimum analysis. Citric acid has always been in the product’s formula, but was not previously listed in the guaranteed analysis.

Q: What is meant by ‘achieving X% of runoff volume’?
A: This means to continue watering until an amount of Clearex solution equivalent to 80%-90% of the volume of the container being used occurs. For example, if you are growing in one-gallon pots, you would flush with the Clearex solution until you achieve a little under a gallon of runoff.

Prior to harvest Clearex only needs a single, thorough, application. For the remaining week before harvest, use plain water without any nutrients or additives.
