Reaching Further, Doing More

We the MicroLife Team are deeply committed to healing the world and providing a bright future now and for future generations. We are all about Mission.

We believe that healthy soils, healthy plants, healthy planet, and healthy people are all connected. As such we take great care in how we manufacture all of the MicroLife products. We make sure that all of our products have the highest nutritional value possible so that all soils, plants, and people benefit.

Truly, the story of Organics is really the story of nutrition. When you feed any organism the highest nutrition possible that organism, be it human, animal, plant or soil microbe, will hit its optimum potential and have less problems. Problems as we know are always expensive so why have them unnecessarily? It’s better to follow natural law.

MicroLife products follow natural law which means everything works smoother, more efficiently, is healthier and is less expensive. Thank you for visiting our web site. We have lots of great information to help you be hugely successful with Organics.

33 Year Battle-Tested Products

1988. That’s when we started manufacturing MicroLife. Our mission then is as it is today; to make the world’s best soil and plant food on the planet.

The History of MicroLife

We devote our lives to bringing to market the healthiest, most nutritious products for Landscape, Horticulture, Agriculture and Garden use. We believe that healthy humans begin with healthy soils, healthy plants and healthy animals.

MicroLife is a wholly owned subsidiary of San Jacinto Environmental Supplies, Houston, TX. San Jacinto Environmental Supplies is a privately held corporation owned by Joyce Serant and Mike Serant. San Jacinto started in 1984 by selling chemical fertilizers and chemical pesticides; the very products we condemn today. Back then though, who knew? We were very successful in selling the junk fertilizers and toxic chemicals. Quickly though we recognized that something was seriously wrong and started to investigate why, when plants were fed with chemical fertilizers did they develop a need for pesticide sprays? After attending many chemical fertilizer dealer meetings and observations with our own eyes we realized that the chemical system was wrong, dead wrong!

In 1986 we began our search for true plant health so we could grow plants without the need for chemical poison sprays. That led us to the wonderful world of Organics and in 1988 MicroLife 6-2-4 was born and we have been manufacturing MicroLife ever since. It was very tough in the beginning and we met a lot of heroes along the way. Fortunately truth, wisdom and science prevailed and here we are 26 years later in the most exciting time in the Organic movement. The evil chemical empire is dying, long live the new business model of health and sustainability… Organics!
