Fearless Gardener Brand - Rock Hard
Rock Hard is a highly concentrated potassium supplement designed to increase the density of your flowers and fruits. Potassium is a catalyst for carbohydrate metabolism and aids in the synthesis of proteins and amino acids. Adding high levels of potassium may lead to thicker, heavier flowers with massive yields.
For use in nutrient solution: Implement Rock Hard up to 3 weeks before flush. Add 0.1g per 1L or 0.4g per gallon for the first week, 0.2g per 1L or 0.8g per gallon for the second week, and 0.5g per 1L or 2g per gallon for the last week before flush.
Instruction for use on its own: Mix 1g per 1L or 4g per gallon.
Rock Hard increases the EC/ppm greatly, so use with caution and remember - less is more! *** Do not foliar spray ***
