Bring Your Houseplants & Tired Potting Soil Back to Life
Hydralife is the live, ready-to-pour biostimulant for your entire houseplant collection, plus roses, raised beds, and small gardens. Built for the depleted potting soil that synthetic fertilizer can't fix. A living liquid microalgae formula that revives the soil microbiome, the fungi, bacteria, and earthworm ecosystem that living plants actually depend on. Ships in breather bags. No mixing, no measuring. Just shake and pour. Use upon receiving for the highest cell activity.
The silent reason your houseplants stop thriving
Healthy soil is alive. It's a complex ecosystem of bacteria, mycorrhizal fungi, protozoa, and earthworms, all working together to break down organic matter, cycle nutrients, and feed plant roots. When you put a plant in a pot, the soil starts with very little of that biology to begin with. Over months and years, what little there is dies off. The soil becomes inert.
The plant survives but stops thriving, leaves get smaller, new growth slows, watering intervals become inconsistent. Roses stop blooming like they used to. Your raised beds produce less every year. Synthetic fertilizer treats the symptom but not the cause. The root cause is missing living soil biology.
Hydralife is a living microalgae biostimulant that feeds that missing biology directly. The exopolysaccharides our cells continuously secrete are the preferred food source for beneficial soil bacteria and mycorrhizal fungi. As the microbiome rebuilds, earthworms and other soil animals follow. The phytohormones in the live cells work on the plant directly, supporting leaf and root recovery while the living soil rebuilds underneath.
What does phytoplankton do for my plants?
Short answer: it makes them grow stronger roots, tolerate drought and heat better, absorb more nutrients from the soil they already have, and, in peer-reviewed trials, produce measurably more leaves, flowers, and fruit. The specific mechanisms:
Stronger Roots. Auxins and cytokinins secreted by living microalgae drive root elongation and lateral branching. Bigger root systems pull more water and nutrients from the same soil.
Richer Green Leaves. Chlorophyll content gains of 17-18% documented in peer-reviewed bean-plant trials with live freshwater microalgae foliar application.
Faster Germination. Seed-soak trials show germination-index improvements across watercress, cucumber, tomato, and other common crops.
Stress Resilience. Abscisic acid, free amino acids, and osmolyte precursors help plants hold water during drought and keep photosynthesis running in heat.
Living Soil Restoration. Exopolysaccharides feed beneficial bacteria, mycorrhizal fungi, and the broader soil food web, down to the earthworms that break down organic matter. Restores microbial activity in aged, depleted, or over-fertilized soil.
Reduced Transplant Shock. Phytohormone inputs at the moment of transplant stabilize the root system and shorten the stall period before new growth resumes.
Higher Yields. A patented live-microalgae application on tomato, pepper, and eggplant reports marketable-yield increases above 150% versus untreated controls.
How is this different from a seaweed or kelp biostimulant?
Seaweed extracts are the most common biostimulant on the consumer market. They are real, they work, and they have structural limitations that live freshwater phytoplankton does not share.
Source: seaweed extract is harvested from the ocean with variable quality. Hydralife is cultivated in controlled photobioreactors, same species, same density, same profile in every bottle.
State when applied: seaweed arrives dried, extracted, and dead. Hydralife arrives alive, active, and actively secreting.
Phytohormone delivery: a seaweed dose is one-time. Living cells keep secreting for hours to days in the soil.
Exopolysaccharides: largely destroyed in seaweed processing. Fully intact in Hydralife, where they feed soil microbes.
Living soil microbiome effect: minimal from extracts. Hydralife is a direct feed for beneficial bacteria and fungi.
How do I use it?
Shake. Pour. That's it. No diluting, no measuring, no math. The more cells in the soil, the more biostimulant your plants get.
Shake: massage the breather bag (32 oz) or shake the jug (1 gallon) gently to mix the living cells evenly through the liquid. Living cultures naturally settle between uses.
Pour: pour directly onto the soil around the base of the plant, the same way you would water it. For houseplants, a small cup around the base. For raised beds, integrate with your normal watering.
Every 2 to 4 weeks: apply every 2 to 4 weeks for plants that need a boost. Safe for edible plants and food crops at every stage up to and including harvest. Use upon receiving for the highest cell activity.
For every plant you grow
Houseplants are our lead audience, especially if you own a lot of them and some have been in the same pot for a year or longer. Pothos, monstera, snake plants, fiddle leaf fig, philodendron, calathea, peace lily, ZZ plants, ferns, and orchids all respond. Hydralife also shines on roses, raised beds, and small gardens where soil volume is limited and soil biology is the difference between plants that survive and plants that thrive.

Frequently asked questions. Is Hydralife Biostimulant safe for vegetables I will eat? Yes. It is a pure freshwater microalgae suspension with no synthetic inputs, pesticides, or chemical additives. Safe for all edible plants at every stage of growth, up to and including harvest. Will it work on orchids and sensitive houseplants? Yes. Use a diluted foliar spray, 0.25 to 0.5 oz per gallon, on orchids, African violets, and other moisture-sensitive plants. For most houseplants, the standard 1 oz per gallon soil drench every 2 to 3 weeks is ideal. When should I start using my bottle? Use upon receiving. Living phytoplankton is biologically strongest in the first few days after harvest. Refrigerate if you cannot apply immediately. Shake gently before each use. Do not freeze. Can I use it alongside my regular fertilizer? Yes. It complements synthetic and organic fertilizers, it does not replace them. Apply them on different days for best results. What does it smell like? A mild, ocean-like aroma characteristic of living microalgae, similar to a clean freshwater pond. It dissipates after application. What happens if I apply too much? It is self-limiting. Excess cells are consumed by soil microbes and mineralize as organic matter. There is no toxicity risk at typical application rates. Is this OMRI-listed or organic-certified? OMRI certification is in progress. The product contains no synthetic inputs and is compatible with certified organic operations under most state rules. Confirm with your certifier before use. Do you ship in winter? Yes. We ship overnight year-round with insulated packaging and cold-weather pack-outs when needed. Will phytoplankton work in hydroponics? Yes. Add to the reservoir at 0.25 oz per gallon of working solution. What is the difference between your biostimulant and your greenwater product? Both are cultivated from the same freshwater phytoplankton species in Denver. The biostimulant is formulated and priced for horticultural use. Greenwater is formulated for aquarists and zooplankton culturists. Different audiences, same underlying culture.
