Choose Hy-Pro Terra for soil, Coco A&B for coco coir or Hydro A&B for hydroponics. These base nutrients cover growth and flowering. With an A&B formula, you need both components.
A root stimulator is a targeted addition to your base nutrients. Stay within the Terra, Coco or Hydro range. For flowering, choose the matching Epic booster: Bloom for Terra, Blast for Coco or Boost for Hydro. Adding more products is not a goal in itself; match your feeding routine to the plant phase, medium and water.
Choose a pack size that suits your usage. Base nutrients come in 1, 5 and 10 litres. Root stimulators and Epic boosters come in 500 ml, 1 litre and 5 litres. Spraymix is available in 500 ml and 1 litre.
