The Reason a Home Fish Ferment Won’t Keep Through Winter the Way a Bottle Does Fall is when a lot of backyard growers put up a batch of something to carry them through the off-season — and a homemade fish fertilizer is a common one to start brewing before the garden slows down. Before that

The Organic Claim We Never Make — and Why That’s the Point at Field Scale Walk through the fine print on any Bloom label and one line shows up again and again, worded almost identically every time: not for use in organic crop or organic food production in the state of California. It’s an easy

A “Live” Tea and a Sterile One Don’t Behave the Same in the Greenhouse — Here’s the Study That Shows Why Compost tea gets talked about in two completely different registers in a cut-flower or ornamental greenhouse: as a nutrient boost, and as something that might help a bench of cuttings fight off fungal pressure.
The Combined Route That Beat Water in a 2026 Wheat Trial — and the One That Didn’t Most of what gets argued about fish-based inputs comes down to a nitrogen percentage on a label. A 2026 trial on fish-processing by-products took a different measurement: instead of stopping at the declared number, it grew wheat with

Before You Add a Silicon Supplement to a Reservoir That Never Gets Flushed Fall is when a lot of semi-hydro and LECA growers stock up and start layering in one more input before the slower winter stretch — and silicon is a common one to reach for. Before it goes into a passive reservoir that

What a Seaweed Extract Actually Turns On Inside a Stressed Root Most of what gets said about seaweed extracts and roots stops at “it helps root development” without saying how. There’s a specific, published mechanism behind at least part of that effect, and it’s more interesting — and more relevant to a small, mineral-poor collection

The Chelate Choice That Matters Most on High-pH Ground Bloom CAL is built for hydroponic reservoirs — the label says so plainly, and nothing here is a suggestion to put a hydroponic calcium-magnesium concentrate on field soil. But the chemistry behind why CAL is built the way it is happens to be the same chemistry

The Study That Found Compost Tea Low-Risk — and Why We’re Printing It Anyway Anyone who has spent time around DIY ferments and compost teas has heard the warning: additives like kelp, fish hydrolysate and humic acid can let dormant pathogens in a brew multiply. It’s a real, sourced finding — USDA Agricultural Research Service

Most product writing about biostimulants cites the studies where the input won. It’s worth being upfront about the studies where it didn’t, because the honest picture in the literature on fish-derived inputs is genuinely mixed — and a garden-variety understanding of what “mixed” actually means helps more than another highlight reel would. The study that
We Looked for a Study Where Fish Fertilizer Failed. We Found One, and We’re Printing It. Read More »
A 2026 meta-analysis of seaweed-extract biostimulants — 198 peer-reviewed studies, over 2,000 treatment-control comparisons — found that powder formulations outperformed liquid ones on average yield response: +22.6% for powder against +15.3% for liquid. For a specialty collector running terrariums, mounted epiphytes, or other small, precisely dosed setups, that number is worth sitting with honestly, because
