HumTeaÂ® was the first beneficial tea to hit the market well over 10 years ago. HumTeaÂ® is not just a fertilizer, rather a specialized blend of proprietary ingredients, humic compounds, sea kelp and earthworm castings. Once brewed, these make a very clean and effective tea that functions as a living topsoil. HumTeaÂ® can be used during all stages of plant growth, transplant through flowering and fruiting, for soil and hydroponics. There is no substitute for the original actively aerated HumTeaÂ®.
