Product description
Atami RokzBastic 100 ml – PK ripening booster, trial size
Curious how a potassium-heavy finisher works in your setup before you commit to a bigger bottle? The 100 ml Atami RokzBastic is made for exactly that. It is a concentrated PK booster from the Bastics range, PK 10-20 with 1% iron and biostimulants, for firm, heavy flowers and fruits in the last weeks.
How far 100 ml goes
The dose is tiny: 0.5–1 ml per litre. One small bottle therefore treats 100 to 200 L of nutrient solution. For a single tent hand-watered from a 10 L can, that is plenty for the full ripening window of a run.
Dosing tip for small batches
At 5–10 ml per 10 L, a pipette or a 10 ml syringe is far more accurate than a cap. Add it together with your base nutrients during the final 4–6 weeks of flower and ripening, ideally straight after BloomBastic, as Atami recommends. RokzBastic raises the EC, so measure after mixing, especially if you combine it with another PK product.
The formula is very low in sodium and chloride, which keeps late flower clean. It works in hydro, coco and soil, by hand or automatic watering.
