Grotek Vitamax Plus: vitamin support for the whole cycle
Plants can make their own vitamins, but it costs them energy, energy they could be putting into leaves and flowers. Vitamax Plus from Grotek gives them that support ready-made: a supplement of vitamins, macronutrients and magnesium to add to your feeding programme from growth right through to the end of flowering.
Why Vitamax Plus?
- Vitamins to support plant metabolism at every stage.
- Added magnesium, the core element of chlorophyll, for deep green foliage.
- Growth and flowering: one product for the whole cycle, with a dose adapted to each phase.
- 100% soluble: safe for hydroponic, aeroponic and drip systems, and suitable for foliar spraying.
