Clearex can be used to fix one of the most common causes of crop failure - salt buildup in growing media. Using mineral based nutrients in growing media can cause the buildup of synthetic salts that lead to shrinkage and death of plant cells due to the excess draw of water through cell walls. This can eventually lead to irreversible wilting of plant leaves and stems. It can also lead to nutrient lockout and later crop failure. Clearex works by drawing salts away from plant roots and grow media while helping to maintain equilibrium during periodic or pre-harvest flushing.

Most flushing products require a 10-14 day flushing window prior to harvest,  reducing the crucial terpene production time in crops. However, Clearex only needs a 3-7 day window prior to harvest. This allows growers to maximize the yield and potency of their crops without jeopardizing flavor.

Flushing with Clearex at the end of a crop’s growth cycle can trigger the last reproductive stage of the plant, forcing it to process and assimilate internally stored nutrients. Pre-harvest flushing with Clearex can enhance overall crop flavors and increase yields by encouraging plants to process excess nutrients.

Usage Application
Mix 2 tsp (5ml) of Clearex per gallon of water. Use Clearex with pure water only. Mix well and adjust pH.

Between nutrient changes: Drain all existing nutrient solution. Add only Clearex and fresh water and allow to re-circulate in your system for approximately two hours. Drain completely and refill reservoir with fresh nutrient solution.
Pre-harvest: Drain all existing nutrient solution. Refill reservoir with Clearex and fresh water only. Begin running this solution during the last 3 – 7 days before harvest during the ripening phase.

For container gardens:
Between nutrient changes: Drench thoroughly with Clearex solution until there is 20 – 40% runoff from the bottom of the pot. Resume regular feeding with your next scheduled watering.
Pre-harvest: Drench daily until 10 – 20% runoff is achieved from the container. Begin running this solution during the last 3 – 7 days before harvest during the ripening phase.
