Roots Organics Surge in the Early Bloom Feed
This is the fish-based piece of the Roots Organics lineup, meant to feed plants and the biology around their roots at the same time. It is made from sustainably harvested marine protein that has been enzymatically processed, then blended with natural sugar, kelp and humic acid. The fish supplies organic nitrogen and phosphorus, the sugar feeds soil microbes, and the kelp and humates help roots use what is there. On the Hydrofarm master feeding schedule for the line, Surge goes in at 5 mL per gallon. It runs from week 1 through week 5 of bloom, then drops out of the chart. Older label directions give a wider range, from 5–10 mL per gallon for seedlings to 5–15 mL per gallon for mature plants. Start at the chart rate and only climb if the plants are clearly asking for more. Shake the jug hard before pouring, since fish solids settle between feeds. Mix it into plain water first, then add the rest of the feed and check pH last. It has the unmistakable smell of fish, especially right after watering. Run the exhaust for a while after feeding in a small, sealed tent.
Why a Microbial Stimulant Belongs in Soil and Coco, Not the Tank
Surge is built for living media, where the sugar and proteins have something to feed. In soil and coco, that extra biological activity is what turns the fish into available nutrients over the following days. Roots Organics pitches it for essential oil production and flower weight through early bloom. The trade-off shows up in recirculating hydro. Fish proteins and sugar can feed biofilm, cloud a warm reservoir and gum up emitters, so most growers keep it to hand-watered or drain-to-waste setups. The analysis on this product has changed over the years. Older bottles read 0.75-0.1-0.5, while current retail listings show 2-2-0.5, so follow the label on the bottle you receive. Either way it is a supplement that sits alongside a base program, not a complete feed. The gallon suits a tent or small room running the full Roots Organics schedule. Anyone just trying it out will find the quart easier to use up while it is fresh.
Key Features
- Fish Protein Base: Enzymatically processed marine protein supplies organic nitrogen and phosphorus for heavy-feeding weeks.
- Natural Sugar: Feeds soil microbes, which drives the nutrient cycling organic growers rely on.
- Kelp and Humic Acid: Support root-zone activity and help plants make use of the nutrients already present.
- Early Bloom Timing: The Hydrofarm schedule runs it through the first five weeks of flower at a single rate.
- Soil and Soilless: Designed for soil and coco programs, with or without the rest of the Roots Organics line.
