HumTea? was the first beneficial tea to hit the market well over 10 years ago. HumTea? 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. HumTea? 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 HumTea?.
