CANNA Coco A and B: One Base Feed for Buffered Coco This is the two-part mineral base feed CANNA developed specifically for coco coir. The listing is the matched set, one bottle of Part A and one of Part B in the size you choose. Part A runs at 4-0-1 and carries most of the nitrogen, while Part B runs at 1-4-2 with the phosphorus and extra potassium. They ship in separate bottles for a practical reason. Held together as concentrates, some of those elements bind into a solid the plant cannot take up. Diluted in the reservoir one after the other, they stay in solution. The label rate is 0.5 fl oz per gallon of each part, which works out to 40 mL per 10 L. That single rate covers the whole cycle. Buffered coco evens out the swing between vegetative and flowering demand, so CANNA sells one formula where most lines sell two. CANNA's recommended window is an EC of 0.8 to 1.8 mS/cm for A plus B over clean source water, at a pH between 5.5 and 6.2. Mixing and Feeding These Coco Nutrients in Drain-to-Waste Mixing sequence is the one habit that matters with these coco nutrients. Fill the reservoir with water first, stir in Part A, then add Part B and stir again. Letting the solution stand for a few hours before feeding gives it time to settle. The feed goes on at every irrigation in drain-to-waste coco, from the first watering after transplant to the last week of flower. Full-grown plants take roughly three to six litres per square metre a day, depending on the room and the size of the pots. Most growers start rooted cuttings at the low end of the EC window and climb as the canopy fills in. It pairs directly with CANNA's buffered coco, including the Professional Plus bag and the COCO Brick. The formula assumes a medium already charged with calcium and magnesium. That is why it earns its keep in coco rather than anywhere else. CANNA points soil growers to its Terra line and recirculating systems to Aqua instead. Keep both bottles closed in a dark spot, away from extremes of heat and frost. Key Features Two-part mineral base: Part A at 4-0-1 and Part B at 1-4-2 together deliver the full base feed a coco crop runs on. One formula start to finish: Buffered coco evens out stage-to-stage demand, so there is no separate grow and bloom bottle to manage. Separate A and B bottles: Keeping the concentrates apart stops elements binding into a form the roots cannot absorb. Single label rate: Half a fluid ounce per gallon of each part, or 40 mL per 10 L, through the entire cycle. Built for drain-to-waste: Made for run-to-waste irrigation in buffered coco such as CANNA Coco Professional Plus. Three set sizes: The 1 L, 5 L and 20 L sets scale from a single tent to a production room.
