The FloraFlex 3/4 GAL QuickFill™ O2 is a premium expandable coco coir growing media designed for clean, consistent performance across hydroponic systems. Each unit expands to approximately 3.2L (3/4 gallon), forming a uniform cube ideal for strong root development and even hydration.
Made from a high-quality coco peat blend, it delivers around 60% water holding capacity, giving you the ideal balance between moisture retention and oxygen availability in the root zone.
The coco is super washed with an EC of < 0.6 (Dutch Method 1:1.5), helping to prevent nutrient spikes and giving your plants a clean, stable start from day one.
Available as single units or full cases of 30.
