Product description
Atami BloomBastic 100 ml – PK 14-15 finishing booster for a single tent
For a small tent or a first try with Atami's classic bloom booster, the 100 ml bottle of BloomBastic is the sensible start. You only use it in the second half of flower, so a small amount covers more than you might expect.
What it does
BloomBastic is Atami's all-in-one bloom booster: stimulator, hardener and flavour enhancer in one bottle. The mineral-organic formula has PK 14-15 and gives plants extra phosphorus and potassium in the final weeks, supporting compact, heavy flowers and fruits with intense aroma. No sodium or chloride is used in sourcing the raw materials. It works in hydro, coco and soil and with every irrigation system.
How far 100 ml goes
At 0.5 to 1 ml per litre, this bottle treats 100 to 200 L of nutrient solution. A tent fed 20 L a week over a five-week finish uses about 100 L, so at full dose the bottle covers roughly one complete finish; at the lower dose, two.
Using it
Start BloomBastic in the last 4 to 6 weeks of flowering and ripening, on top of your base nutrients. A 5 or 10 ml syringe makes these small doses easy. It raises the EC of your solution, so measure after mixing and adjust the base feed if needed. Atami advises against running another PK booster at the same time, to avoid overfeeding.
