For budget-conscious users, Sea-K makes an excellent go-to bio-stimulant.

Application Information:
We strongly recommend applying Sea-K using a pump or battery-powered hand sprayer for precise coverage. After application, water it in with at least ¼" of irrigation or rainfall.
While a quart hose-end sprayer can work, a pump or battery sprayer gives you better control over this concentrated, premium product — helping ensure none of it goes to waste. Watch our hose-end sprayer tutorial video for guidance.
Pro Tip: Start with the higher rate on your first application, then switch to the lower rate for the rest of the season for excellent results.

Humic-12
N-Ext
N-Ext Humic12™ Overview N-Ext Humic12™ is a leading bio-stimulant designed to enhance overall soil health. With a 12% humic acid concentration, it is significantly stronger than most products available to DIY users. Key Features Coverage: One gallon treats up to 21,300 sq ft Analysis: 0-0-1 (N-P-K) Humic Acid Content: 12% bio-stimulant concentration Benefits: Promotes root growth, increases chlorophyll content, improves nutrient uptake, enhances soil structure, boosts water retention, and elevates overall plant quality Available in multiple sizes Product Description Humic12 is a liquid humic acid solution that makes an excellent addition to any fertilizer program, particularly for addressing soil deficiencies. Humic acid is essentially the end product of organic matter decomposition — primarily plant material broken down over time into its simplest form by microbes. Think of it as highly concentrated, odorless microbe byproduct: incredibly small, remarkably nutrient-rich, and exceptionally beneficial for your soil. Chemically, humic acid is composed of carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur. It earns the designation "acid" because it can donate a hydrogen ion (proton) to other substances — and that's precisely what makes it so effective. Humic acid acts as a chelator (pronounced kee-LAY-tor), meaning it makes nutrients more accessible and usable by plants. Think of it as a bridge connecting soil nutrients directly to your lawn's roots. In practical terms, applying humic acid and watering it into the soil helps grass roots draw more naturally occurring nutrients from the ground while simultaneously improving the efficiency of any fertilizer you apply. In automotive terms, it's the equivalent of adding a shot of nitrous oxide to boost performance. What sets N-Ext Humic12™ apart from competitors is its proprietary "long brew" technique, which uses high-quality oxidized lignite to produce a cleaner, more flowable product with superior biological activity.
