Build-A-Soil Build A Soil Liquid Hemp Extract 1 Gallon
Hemp Fermented Plant Extract is made on a small farm near Paonia, Colorado using natural probiotic farming practices. The farm has operated under the direction of Miles Filippelli since 2016 to produce high quality plant inputs for the Fermented Plant Extracts product line. Lactobacillus bacteria are saprophytes, meaning they are decomposers that break down organic matter. That trait is harnessed in making the extract: lactobacillus are fed specific nutrient dense food sources to break down plant compounds and extract them into a liquid form. The mix is fermented until the plant matter is digested and extracted into the liquid and the sugars are consumed by the microbes, which locks in the pH for stability and ease of use in the garden. What's in it Clean mountain water Hemp (plant matter) Molasses Sorghum syrup Lactic acid bacteria sourced from local goat whey EM-1 Why use it This fermented plant extract is made from hemp, a plant known to be nutrient dense, fibrous and beneficial for local biodiversity. The extract is particularly useful for vegetative growth and in the transition from veg to bloom. It is very well rounded and can be used at any time of growth, and it is particularly beneficial in the bloom cycle as well. How to use Soil drench: 1 - 4 oz to 1 gal of water Foliar spray: 1 - 4 oz to 1 gal of water Field application: 10 - 30 gal per acre Compost booster: 4 - 8 oz to 1 gal of water Storage and cautions Store in a cool and dark place at room temperature, 68F to 86F (20C-30C), and out of direct sunlight. Keep out of reach of children. Avoid contact with eyes or open wounds. Not for human consumption. Useful info Lactobacillus varieties are: Antipathogenic - they are effective and beneficial microbes that outcompete and overcome "the bad guys," or pathogenic microbes. Ubiquitous - they are everywhere. Facultative - surviving in both aerobic and anaerobic environments. Microaerophilic - preferring environments with less oxygen than typical environmental air, similar to conditions in soil. Rod shaped - bacillus means "wand" or "small staff." Heterofermentative - translates to producing a variety of outputs including nutrients, CO2, yeasts, acids, and carbohydrates, which plants crave.

Build-A-Soil Build A Soil Pumice - 1CUFT
Last Longer Than Perlite & Has More Minerals 3/8" x 1/4" Pumice is perfect for potting soil.Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurization freezes the bubbles in the matrix. How To Use Pumice Use for potting soil at 15-40% by Volume
