Looking to give your seedlings and clone a healthy start? At Groindoor.com, we feature the best root stimulants and enhancer to help you yield monster harvests.

Young or newly transplanted plants normally fail to develop a healthy root system. This becomes a major hindrance in their growth, as they struggle to receive enough water and nutrients. Fortunately, you can find products to solve this issue. We feature brands including Atami B’cuzz, DynaGrow, Hormex, Fox Farm, Roots Organics, and others.

What are plant root stimulators?

They are known by many different names, such as root boosters, root stimulants, and rooting hormones. Their purpose is, as their name suggests, boosting or stimulating root growth. They contain hormones that promote the root system's growth and reduce waste and mineral build up in the root system.

What are stimulants made of?

Many root stimulants contain mycorrhizae, which enhances root health, allowing them to go deeper and increase their water and mineral intake. Apart from this, stimulants also contain nitrogen, phosphorous, potassium, auxin, and Vitamin B1.

Experts understand that root enhancers do not only improve growth, but they also help plants fight diseases.
