Product description
Canna PK 13/14 10 L – bulk phosphorus and potassium for large-scale flowering
This is the can for commercial-size rooms and growers who run multiple flowering rooms in rotation. When a PK week comes round every few weeks, the 10 L size keeps you stocked for a long time at the lowest cost per litre in the range.
Ten litres, in tank fills
At the maximum of 1.5 ml/L you can treat about 6,650 L of nutrient solution. A 500 L reservoir takes 750 ml per fill, so one can fills it about thirteen times. With a 1,000 L tank (1.5 L per fill) it still covers about six fills.
Why growers use it
Canna PK 13/14 (NPK 0-13-14) gives plants a concentrated dose of phosphorus and potassium at the moment they need it most, when flower sites start to stack and swell. A short, targeted application supports large flower clusters and firm, dense fruit in soil, coco and hydro.
Dosing at this scale
Give it for about one week at 50–60% of the flowering period, around week 5–6 in an 8-week bloom, on top of your normal feed. In bigger rooms a dosing pump on the mixing tank keeps every batch identical. Potassium lowers pH, so recheck it after mixing, and reduce the dose if calcium or magnesium deficiency shows up.
Store the can upright, sealed and frost-free, and decant a working amount into a smaller bottle rather than opening the big can every time.
