Diluting seawater drops its salt load fast, but its sodium-hazard ratio falls only at the square root of that dilution — and the math changes everything in a reservoir too small to buffer it.

The Potassium Your HUMATE Leaves Behind — And Why a LECA Reservoir Never Rinses It Out Science & Education · Semi-Hydro & Houseplant growers Every commercial humic-acid product starts the same way: raw leonardite or lignite ore, where the humic fraction sits locked up as insoluble calcium, iron and aluminum humates. To get it into

The Mineral a Kelp Steep Runs Out of First Semi-Hydro & Houseplant · Science & Education Steep dried kelp in a jar for a LECA reservoir top-up and the pitch is usually about what it delivers — potassium, trace minerals, “biostimulant” compounds. Nobody asks what runs out first. It turns out one mineral hits a

The Bottle-Size Math Nobody Runs for a LECA Reservoir Semi-Hydro & LECA Houseplant · Buying & Stocking Up Fall is repotting season for a lot of semi-hydro growers — last chance to settle a plant into fresh LECA before light levels drop and growth slows for winter. It’s also, conveniently, when a lot of people

When Two Versions of Our Own Label Disagree, We Print Neither Number Semi-Hydro & LECA Houseplant · Brand & Experience In a passive LECA reservoir, there’s no weekly flush diluting a mistake away. Whatever concentration goes into that water column sits there, feeding the roots sitting in it, until the next full change — which

Every propagation-station post on the internet tells you to steep willow twigs for free rooting hormone, drop a pothos cutting into a jar of LECA and your diluted willow tea, and wait. Almost none of them ask the one question that actually decides whether that tea does anything at all: which willow is it? The

Most of what gets said about Bloom CAL focuses on the obvious headline numbers — the calcium, the magnesium, the iron DTPA chelate that holds up in high-pH water. The label carries a fifth declared nutrient that almost never comes up: zinc, at 0.0360%, chelated as zinc EDTA. In a passive semi-hydro or LECA reservoir,

The Fish Behind Seafuel, By the Numbers “Fish hydrolysate” on a label tells you almost nothing — it could be menhaden scrap, salmon trim, or something else entirely, all lumped under one generic phrase. Seafuel’s label is specific: Southern Bluefin Tuna, Thunnus maccoyii. In a reservoir that might only hold a liter or two, knowing

A small reservoir sitting on a kitchen counter, feeding a houseplant in LECA or a semi-hydro setup, doesn’t get flushed often. Whatever’s actually in a fish-derived input matters more there than in a run-to-waste system that gets rinsed every week. So it’s worth asking a question most feed charts skip entirely: when two bottles both

What “Fish-Derived” Actually Means for a Reservoir Sitting on Your Kitchen Counter A semi-hydro setup lives in your living room, not a greenhouse. When an input’s ingredient list includes fish hydrolysate, it’s a fair question whether that changes anything about having it around pets and kids. Semi-hydro and LECA growers keep their reservoirs somewhere a
