Yes, Huntin products are advised to use repeatedly again, and again, it will work more and more effectively with repeat use.

No, all Huntin products are totally harmless, residue-free, and safe for honey bee, predators, soil earthworms, waterbodies, biodiversity. In fact, many of the Huntin products reduce the toxicity caused by many dangerous chemicals regularly used in farming.

Everything is linked to how we utilize energy and use for production like in Potato, if farmers plan the fertigation based on 30 metric tone or more target yield, day wise, week wise, month wise improvement can take the yield even more than 30 metric tone. But it is really possible with step-by-step compounding effects, one of the missing links is ignorance of biology in the soil, which is the foundation for high yield, 100% true chemistry can be zero without good biology. By using seed grow++ as per Huntin's schedule and other fertilizer planning, this 30 metric tons/acre every year is achievable.
