Its streamlined program makes nutrient application easy and avoids having to combine numerous products. For this reason, it is an especially suitable option for beginner growers or for those who want to try the Boom Nutrients range through an economical pack.

The formulation of these fertilizers combines mineral nutrients and natural extracts, with components available for the plant to assimilate correctly.
What does the Start Tripack contain?
- Roots Boom (250 ml): a stimulator intended to promote the development of a healthy root system with a greater capacity to absorb water and nutrients. It is recommended to apply it once a week until the beginning of flower formation.
- Crecimiento Boom (250 ml): a base fertilizer formulated in one part to provide essential nutrients during vegetative growth. It helps to achieve vigorous, well-branched plants prepared to face flowering.
- Floración Boom (250 ml): a base fertilizer to cover the plant’s nutritional needs during the flowering stage. Its formulation promotes the progressive development of flowers until the final weeks of cultivation.
The three products have a simple application schedule: they are normally used once a week, alternating with a water-only irrigation. However, it is always advisable to adjust the dose to the state of the plants and consult the manufacturer’s feeding chart.
This pack provides basic nutrition for rooting, growth, and flowering. If you wish to develop a more complete program, it can be supplemented later with specific Boom Nutrients stimulators or additives.
