HESI Bio Grow is the plant-origin growth feed in the HESI range. It suits growers who want an organic-style base fertilizer for active foliage growth.
For organic-minded growers
It suits growers looking for a vegan, plant-based feed. It works best when the substrate and watering habits also support organic care.
Where mineral feeds fit better
For long-standing reservoirs or inert-media setups, choose a hydro or coco nutrient with faster mineral availability and more precise water control.
Most fertilizers and additives are packed and shipped separately from plants.
Because of this, they may have their own shipping charge. Your final delivery cost is shown at checkout and is calculated by the total weight of your order.
Free shipping does not apply to fertilizer and additive products.
