  • Floraflex Nutrients | Root Drip (55 gal Drum)

    FloraFlex Nutrients Floraflex Nutrients | Root Drip (55 gal Drum)

    In stock

    Root Drip is a root, irrigation and PM cleansing agent. Derived from salt and a propriety electrochemical treatment process. Root Drip is a plant- safe chemical with powerful oxidative properties that contribute to improving both Nutrient and Oxygen availability, creating a clean root zone free of unwanted organic and mineral buildup. Key Features Double Strength Non-toxic Neutral pH Use as a flush Prevent mineral build-up Increase Oxidation-Reduction Potential (ORP) Root zone EC optimizer Irrigation system descaler PM Cleanse How To Use: Irrigation System Maintenance:For best results, add 1 mL to every gallon of water for regular maintenance. Irrigation systems that are regularly maintained with Root Drip will last longer, and run more optimally throughout. Root Drip helps break down scale, mineral buildup, and other organic matter that has been in the system. Severe Conditions:Increase rate to 2-5 mL per gallon of water for severe reservoir and growing media conditions. Foliar Applications:Mix 190 mL Root Drip per gallon water and spray evenly. Test on a small area first to ensure no damage.  Surface Cleaning:Spraying cultivation surfaces, work areas and irrigation equipment with a dilute solution of Root Drip (190 mL per gallon) helps maintain a clean and trouble-free environment without toxic and dangerous chemicals. Maintain operational excellence and extend equipment life, such as irrigation system filters, by running treated water through the system regularly.  Clones:Dip fresh cuttings in a solution of Root Drip (10 mL per gallon) to improve cell health and increase immunity. Seedlings and cuttings treated with Root Drip have more vigorous growth. Roots of plants treated with Root Drip will be bright white with increased root hairs.  Media/System Flush Mix:Use Root Drip at a rate of 2-5 mL/ gallon of water during the final flush stage or any phase of vegetative or flowering growth to help reduce mineral buildup in the growing media or irrigation system.  RDWC and Other Recirculating Hydroponics Systems:Any deep water culture (DWC) or recirculating irrigation system should use Root Drip to remove mineral residue and reduce scale. Irrigation water treated with Root Drip has a reduced risk of developing problems that are often associated with overwatering and insufficient oxygen levels, such as biofilm buildup and/or anaerobic microbial growth.

    Cyco Cyco Dr Repair - 5L

    In stock

    Cyco Dr. Repair treats chlorosis and environmental stresses. Chlorosis is a yellowing of leaf tissue due to a lack of chlorophyll. Possible causes of chlorosis include poor drainage, damaged roots, compacted roots, high alkalinity and more importantly nutrient deficiencies in the plant. Environmental stress can damage plant function or its development, which shortens the time for photosynthesis and in turn reduces yield. The lack of iron is one of the more common nutrient deficiencies in plants associated with chlorosis. Dr. Repair helps to restore your plant to its full potential.
