CANNA PK 13/14 is a high grade mixture of phosphorus and potassium that is added during the flowering phase. Both elements play a big role during the generative phase of plants.

Root Stimulators from Dutch Pro

Take Root contains several plant hormones and micronutrients, that enhance the cellular division, and the movement of nutrients around the root zone. These ingredients help with overall root development, especially during early vegetative growth.

It is important to provide some kind of root enhancer during the early days of veg, and when repotting or transplanting your plants. A good healthy root zone, will bring you a good healthy plant.

Flower Boosters from Dutch Pro

Like any other brand, Dutch Pro offer a Flowering enhancer. It has a higher amount of P and K to give the plant the extra energy it needs to build big buds.
