Nectar For The Gods Poseidonzime Kelp is a liquid kelp concentrate formulated to deliver naturally occurring potassium to plants through root feeding, foliar application, or compost tea preparation. The 5-gallon size is designed for commercial cultivation operations where large reservoir volumes or frequent foliar programs make smaller bottles impractical. Poseidonzime is noted for being extremely gentle on plant tissue, making it suitable for sensitive seedlings and established crops alike.

Why Choose Poseidonzime Kelp
Poseidonzime Kelp addresses a specific gap in most nutrient programs: a low-risk, plant-gentle way to deliver potassium and metabolic cofactors without the harshness of synthetic salt-based K sources. Here is what sets it apart based on the canonical product description:
- Natural potassium source: Derived from kelp, the potassium in Poseidonzime is present in organic, chelated forms rather than as concentrated inorganic salts. This makes it less likely to cause tip burn or salt stress when used at label rates.
- Extremely gentle on plant tissue: The product description specifically notes gentleness — useful in programs where plant tissue is sensitive, such as during transplant recovery, light stress periods, or late-cycle finishing.
- Triple-application flexibility: Poseidonzime works equally well as a root feed drench, a foliar spray, or an additive to compost tea brewing. Growers running multiple application methods do not need separate products for each method.
- Compost tea compatibility: Liquid kelp is a well-established food source for microbial populations in actively aerated compost teas. Adding Poseidonzime to a tea brew supports faster microbial colonization and a richer microbial profile before inoculation.
- Metabolic potential support: The canonical description references increased metabolic potential — a general reference to kelp’s cytokinins and auxin-like compounds that influence cell division rates and uptake efficiency.
Best Uses for Poseidonzime Kelp
Poseidonzime fits into a range of cultivation workflows, from soil-based organic gardens to coco and hydroponic systems running a living-root program. The following uses are derived from the canonical description and the product’s category placement (Additives — Growth & Bloom Boosters):
- Weekly root drench in soil and coco: Add to your reservoir or hand-water mix at each irrigation to maintain a steady baseline of natural potassium throughout the vegetative and bloom phases.
- Foliar spray for rapid uptake: Mix a diluted solution and spray leaves directly during lights-off or early morning when stomata are open. Foliar application is particularly effective during recovery from deficiencies or environmental stress.
- Compost tea additive: Include Poseidonzime as a food source when brewing actively aerated compost teas. It helps sustain bacterial and fungal populations during the brewing cycle before the tea is applied to soil or media.
- Late-cycle potassium supplementation: During the bloom and finishing stages, plants require elevated potassium for bud development and sugar transport. The gentle format of Poseidonzime makes it a lower-risk option than aggressive K boosters at this critical stage.
- Large-scale commercial programs: The 5-gallon format reduces per-application packaging cost and is practical for operations dosing multiple large reservoirs or sprayer tanks per week. Pair it with a carbohydrate supplement like Earth Juice Hi-Brix Molasses to further support microbial activity in living root programs.
Compatibility
Poseidonzime Kelp is designed to integrate into the broader Nectar for the Gods nutrient system, which is formulated around calcium-rich bases, enzymatic additives, and organic-form micronutrients. However, the liquid kelp format is compatible with most third-party nutrient programs given its gentle, low-salt profile.
Growing media: Suitable for soil, amended living soil, coco coir, and hybrid media. For purely recirculating hydroponic systems (DWC, NFT), use at low rates and monitor EC carefully, as organic inputs can affect dissolved oxygen and microbial load in reservoir systems.
Other additives: Poseidonzime pairs well with microbial inoculants and enzymatic products. If you are running a biologically active root zone, microbial inoculants like Advanced Nutrients Tarantula complement kelp-based feeds by colonizing the beneficial bacteria and fungi that kelp supports.
pH range: Specific pH compatibility data is not published in the available product documentation. Follow Nectar for the Gods’ general guidance for the full line, and verify reservoir pH after adding any organic concentrate to your mix.
Growth stages: The canonical description does not restrict use to a particular growth stage. Poseidonzime can be used from seedling through late bloom, adjusting the dose rate to match the plant’s developmental needs.
Dosing Guidelines
Specific mL-per-gallon dose rates for Poseidonzime Kelp are not included in the available canonical product data. The following guidance is based on the product’s category (liquid kelp additive) and standard industry practices for this product type. Always defer to the current Nectar for the Gods feed chart for precise rates.
- Root drench / reservoir: Typical liquid kelp additives are used at 1–5 mL per gallon depending on growth stage. Start at the low end during vegetative growth and increase modestly during early bloom. Do not exceed manufacturer-recommended maximums.
- Foliar spray: Dilute more aggressively for foliar application than for root drench — over-concentration in a foliar mix can cause leaf burn even with gentle products. A starting point for most kelp concentrates is 1–2 mL per gallon of spray solution.
- Compost tea: Add to actively aerated tea brews as a food source for microbes. Quantity depends on batch size and the microbial inoculant being used; follow the tea recipe’s guidelines for organic additives.
- Shake or stir before measuring: As with all liquid concentrates, invert or stir the container before drawing each dose to ensure even distribution of the product’s suspended solids and organic matter.
