Product description
Atami ATA PK 13-14 10 L – PK bloom additive in bulk for large grow rooms
For big rooms and professional set-ups that run bloom after bloom, the 10 L container is the economical choice, with the lowest price per litre of the three sizes.
What it is
Atami ATA PK 13-14 is a universal PK bloom additive: 13% phosphorus and 14% potassium (w/w) on top of your regular NPK base feed. During flowering your plants need extra P and K for flowers and fruits, and this delivers it in soil, coco or hydro. You can add it every day, from the first week of flower, at 0.25–1.5 ml per litre.
Scale: up to 40,000 L
At 1.5 ml/L, 10 L treats roughly 6,700 L of nutrient solution; at the low end of 0.25 ml/L it's up to 40,000 L. A 500 L tank needs 125 to 750 ml per fill across that range.
Dosing and storage
At these volumes a dosing pump set to your current rate is the easiest way to build up gradually without measuring by hand, raising the setting a step each week. Shake the container, decant into a smaller bottle for daily work, and keep the bulk sealed and frost-free. Before harvest, switch to plain water and enzymes for the final week.
