Plant fertilizers and additives
Plant fertilizers and additives are extremely important for healthy and vigorous growth and optimal flower development. Without the addition of special fertilizer, deficient symptoms often occur in the rapidly growing crops, which have a negative impact on the development of the plant. This automatically leads to lower yields and reduced potency.
We have the best branded fertilizers from Plagron, Mills, Hesi, BioBizz, Advanced Hydroponics, CANNA etc. for you. These are specially tailored for cultivation on soil and coco or optimized for hydroponic and aeroponic. These fertilizers ensure an ideal nutrient supply for your plants and ensure excellent yields. We have a wide selection of purely organic fertilizers for you.
