Premium Cold Pressed CleanKelp Growing Supplement
$19.99
Bloom City’s CleanKelp formulation contains seven species of wild harvested sea plants that are loaded with vitamins, minerals, and naturally occurring plant growth hormones. CleanKelp improves root and stem growth, relieves heat and drought stress, and combats predators to ensure plants grow vigorously. Add CleanKelp to your everyday watering routine or use it for root dips, foliar sprays and compost teas.
Other kelp brands fill their bottles with low quality byproduct and non-nutritious plant matter. Stop paying for filler material. Bloom City’s proprietary extraction methods are gentle and maximize the nutritional benefits of wild sea plants. CleanKelp is rich in naturally occurring enzymes, amino acids, sugars, minerals, growth hormones and macronutrients.

Premium Silica Boost Growing Supplement
$18.99
Bloom City’s Silica Boost formulation delivers water-soluble silica directly to the plant’s roots. Improves heat and drought tolerance, increases resistance to environmental and pathogen stressors, and improves water uptake in the root zone. Silica Boost builds strong plant cells and increases growth. Add Silica Boost to every watering to keep plants healthy.
Other Silica brands use un-available forms of silica, which will sit locked-up in your root-zone for weeks before roots can uptake the minerals. Slow uptake times mean much less effective results. Bloom City’s proprietary 100% organic acid complexed Silica Boost increases bioactivation, which means much faster uptake times and stronger plants.
