CANNA Coco B Brings the Phosphorus to the Coco Feed
Open the reservoir lid on any coco grow running CANNA and this is the second jug poured. Part B is labelled 1-4-2, so it carries the phosphorus and the larger share of the potassium in the feed. Part A covers the nitrogen side. CANNA keeps the two in separate bottles because a coco feed needs a lot of calcium and a lot of phosphate. Held together as concentrates, those elements react and settle out as a residue the roots cannot use. Once diluted in water one after the other, they stay dissolved and available. The label rate is 0.5 fl oz per gallon, which works out to 40 mL per 10 L, matched exactly by Part A. Combined, CANNA's window runs from an EC of 0.8 to 1.8 mS/cm over clean source water. The target pH sits between 5.5 and 6.2.
Running CANNA Coco Part B From Bottle to Bulk Tote
The routine never changes from one feed to the next. Water goes into the reservoir, Part A goes in and gets a stir, then Part B follows and gets another. Measure each part with its own cup or syringe. A drop of one concentrate in the other's cup starts the very reaction the two bottles exist to prevent. The same dose runs through veg and flower, because buffered coco evens out how much the plant asks for between stages. That is also why this line has no separate bloom base. Part B is sold singly for growers who restock by the part, or who run injectors with one head per concentrate. The bottle and jerrycans suit tents and small rooms mixing by hand. The drum and the caged tote belong in facilities dosing from bulk, with the pump, spill tray and forklift access to handle them. Store it sealed, dark and frost free. Fed without Part A, a crop quickly shows nitrogen hunger, so it never goes in alone.
Key Features
- 1-4-2 phosphorus half: Supplies the phosphorus and the larger potassium share that Part A leaves out.
- Poured second: Always added after Part A has been stirred into the reservoir water.
- Same rate as Part A: Half an ounce per gallon of each part, from rooting through harvest.
- Five container sizes: A 1 L bottle, 5 L and 20 L jerrycans, a 200 L drum and a 1000 L IBC tote.
- Injector ready: Runs on its own dosing head alongside Part A in drain-to-waste coco.
- Made for buffered coco: Built for pre-charged coco substrates rather than soil or recirculating hydro.
