Description

PK Bulk is a concentrated PK booster that is used alongside your base nutrient to deliver rapid growth and development during the flowering stages. As well as containing a plentiful supply of phosphorus and potassium, PK Bulk's formula also includes special hormones derived from natural sources that accelerate fruiting while toughening plants against environmental stresses.

We recommend using silicon at the same time, so that your plants can develop branches strong enough to support the weight of the fruits you're going to produce.
