Growhard PK Boost - 20L

For Enhanced Flowering: During the flowering phase, the demand for phosphorous and potassium markedly increases. Inadequate levels can impair plant growth and reduce flower output.

PK BOOST is designed to augment phosphorous and potassium concentrations, promoting larger flowers and increased yields.

Directions for use:

Add 1-2 mL of PK BOOST per litre of flowering nutrient solution during week 4 & 5 of flowering.
