At Kings Greenhouse we are proud to offer Biodiversity products.


Why? Take a look at their mission statement:



We put our environmentally conscious awareness into action with a truly remarkable, all natural, organic product and service line.
Marrying ancient philosophy with modern practicality, our fertilizers, amendments and soils are formulated to provide our customers with organic, earth friendly products that warrant unprecedented results.

Biodiversity has always believed, and supports the concept that using sustainable agricultural practices is the key to our survival on this planet. The implementation and education of cutting-edge “earth friendly” methods will create more biomass (GROW), save in resources (SAVE), while constantly building and replenishing a healthy eco-system (PROTECT). Biodiversity GSP meets these challenge through its products and services.

Over use of synthetic and/or petroleum based fertilizer is detrimental to our environment, costly, and destroys our critical and vital top soil. While the use of chem-based fertilizers are an important part of successful commercial agricultural practices, there still needs to be a balance between all 3 aspects of soil - Chemical, Biological and Structural. Biodiversity is determined to educate, learn from, and support companies as they create long term objectives for sustainable practices and economic success where everyone wins.


BioDiversiTEA BioBizz Alg-A-Mic, 5 L
Our Price: $5.00
Our Price: $175.00
1 Gallon of BioDiversiTEA Listed by the Organic Materials Review Institute (OMRI), this all-natural energy booster contains concentrated seaweed, trace elements and hormones of vegetable origin, amino acids, and vitamins. Alg-A-Mic can be used as a soil drench or as a foliar feed.

Alg-A-Mic is a revitalizing product made from a high grade, organic seaweed concentrate extracted through cold pressing rather than chemical solvents. It contains a high level of natural nutrition that caters to the whole spectrum of plants needs, resulting in exuberant green foliage. Seaweed has been harvested for food, fertilizer, and medicine for thousand of years. History books record that the Chinese used seaweed for medicinal purposes as early as 3000 B.C.

Alg·A·Mic™is not a fertilizer and unlike many Bioboosters on the market today, Alg·A·Mic™ is the organic alternative and might be used along with regular nutrition.
