The #1 BLOOM BOOSTER for serious growers
Resin-XS is a specialised flowering additive for use in conjunction with “PK” additives.
Directions for use
Use Resin-XS throughout the flowering / fruiting phase. Add to existing nutrient solution at 2-4ml/L then stir well. Use this solution for every watering.
As a general rule, the higher dose rates should only be used for heavy feeders in the mid-late flowering phase.
