Mary Jane's Boost

For the biggest and sweetest harvest

Mary Jane’s Boost fertilizer is specifically tailored to all your plants’ nutritional needs in the second half of the flowering phase. Your plants will receive a strong PK boost which significantly increases the quality and quantity of the harvest. 

Our fertilizers contain the ideal ratio of high-quality mineral and organic components to optimally develop your plants. Using Mary Jane’s Nutrients will result in a large harvest of the finest quality!

Because of our fertilizers’ high concentration & buffering qualities you only need to feed your plants once or maximum twice a week. (Measuring of EC-values is not needed because organic nutrient values can’t be measured correctly)

We strongly advice to start feeding only once a week because that is usually enough. Sometimes plants require feeding twice a week, depending on every plants different nutritional needs, plant size, pot size and growing medium. For more feeding advice you can check our Nutrient Schedules in the downloads section.

Dosage: 1g/2-3L, 1 to 2 times a week.
