Product description
Atami RokzBastic 50 ml: product details and use
Atami RokzBastic 50 ml is a concentrated PK bloom and ripening booster from the Bastics range. Its mineral and biostimulant blend with PK 10-20 and 1% iron puts the emphasis on potassium, for firm, heavy flowers and fruits in the final weeks. Like BloomBastic it is very low in sodium and chloride. The 50 ml bottle is a trial size: ideal for testing RokzBastic before you move to a larger bottle, or for a single small grow tent.
