Grow Methods

The life-cycle of a plant can be divided into 4 stages, in each stage the plant has different nutritional needs. Our fertilizer-line consists of 4 products: Roots , Grow , Bloom  and Boost . Each product belongs to 1 of the 4 stages of a plants life-cycle and has a unique and precisely formulated composition of macronutrients, micronutrients, enzymes, fatty acids, vitamins, stimulators, fulvic acids, humic acids and citric acid, to ensure your plants get exactly what they need in every stage of their life-cycle.

Mary Jane’s fertilizer-line is designed to be simple to use for everyone and to give professional results. Still, depending on your growing needs you don’t always have to use all 4 products. Thats why we divided our fertilizer-line into 3 user levels; Basic, Intermediate and Expert.

You can use our
Nutrient Schedules in the downloads section to get a clear overview of when to use each product.



Basic level

Only 1 product will keep it




When you just want to supply your plants with a bit of extra nutrients now and then to keep them green & healthy you don’t need to do much. Our Grow  fertilizer can be used as an all-round fertilizer for all indoor and outdoor plants and will do the job.

If you are growing plants that produce flowers, fruits or vegetables and you want to make them a bit happier you could add Boost  fertilizer to your nutrient schedule in the 2nd part of the flowering phase which will give a noticeable larger harvest.
