Active soil base · Small batch
Terra Matter Biostart is a hand-calibrated soil base — 25% worm castings, 400+ strains of fungi and bacteria, pH 6.0–7.0, low starting EC. Mixed by hand in small batches. You give water, light and your feeding program — Biostart plays the buffer.
What actually does the work
You only see half of the plant. The other half sits underground and decides everything — how much mass you pull, how fast, what it tastes and smells like. Biostart is built around the root doing work, not around how the soil looks in the bag.
Roots don't just pull water and nutrients — they also produce natural hormones (cytokinins) that drive growth above the soil. The bigger the root system, the more stem, leaf, flower and fruit. Biostart's loose structure and low starting EC push the root to expand instead of playing defense.
Mycorrhizae (fungi that partner with the root) wrap around it and send their own hair-thin strands deep into the soil. The plant's effective reach grows several times over — it pulls water and micronutrients from places the root alone can't touch. That's why 14 days of autopilot on worm castings carries the whole veg.
The root is live tissue — it needs oxygen the same way the leaf needs light. Perlite, peat and Biostart's heavily aerated structure leave air pockets in the medium even after a heavy watering. Less rot, less overwatering, a healthy white root system all the way to harvest.
Living microbiology takes up the space around the root before pathogens can move in. Low starting EC also protects the fresh root from burn. A clone goes into Biostart and immediately pushes new white root hairs — you see it with the naked eye on the first pot check.
Why the base matters
Every all-mix on the growshop shelf is good at something — not every one is good at what you're doing. Biostart is a recipe built for the craft grower, not for a distributor's shelf.
Mass-market all-mix
Production engineered for chain distribution — one recipe, big volumes, constant availability. A safe, proven pick on the standard growshop shelf.
Universal recipe by necessity: a compromise between "safely empty" (Light-Mix) and "loaded to the brim" (Batmix/All-Mix). Either you feed from day one, or you watch the meter very closely.
To pull full potential out of a medium like that, you usually add root stimulants, boosters and humic acids. Safe and predictable — but not cheap on day one.
Terra Matter Biostart
Small, limited batch. Recipe run by Nash Growshop (Český Těšín) — raw-material suppliers picked by hand, not by tender.
400+ strains of fungi and bacteria work with the root from the first watering. Arbuscular mycorrhizae (fungi that partner with the root) start wrapping it within a few days.
Calibration sits on purpose in the middle: stronger than Light-Mix, gentler than Batmix. 25% worm castings carry the kick, low starting EC protects fresh clones and seedlings.
How it works over time
Biostart is built for ~14 days of autopilot and a clean handoff into your feeding program — organic, mineral, hybrid.
Worm castings (25%) + living microbiology act as a slow-release starter buffer. You pour plain water at pH 6.0–6.5. No boosters, no bottled root stimulants, no bottled humic acids — those are already in the soil. Across these two weeks the plant builds a strong root system that carries it through the whole rest of the cycle.
Once the worm-casting reserve runs out, the soil isn't "empty" — it's colonized. From that point on your program takes over: Athena Pro Line, Terra Aquatica TriPart, Plagron Terra, BioBizz Bio-Grow/Bloom, Canna Terra, an organic tea — whatever you're set up for. The microbiology built into Biostart stabilizes pH and breaks organic inputs down into forms the root can actually take up.
What you get out of it
When the root has access to mycorrhizae and a diverse flora, the plant pulls in micronutrients that purely mineral systems just can't deliver. You taste it on the plate, in the jar and in the nose.
Vegetables and fruit from living soil measurably carry more sugars than the same varieties grown in purely mineral mediums — you can confirm it with a refractometer (Brix). Plain language: flavor instead of water under the skin.
Herbs and aromatic plants develop a more complex bouquet. Mycorrhizae unlock micronutrients (manganese, zinc, boron) that are the building blocks of essential oils and aromas.
Leaves deepen their color through better uptake of iron and magnesium — not through nitrogen overfeeding. Monsteras, philodendrons and palms hold their color without bottled chelates.
What's sitting under the root
Microbiology isn't one species printed in big letters on the bag — it's a team that cooperates. Biostart carries over 400 strains of beneficial bacteria and fungi, including mycorrhizae. Together they build a living root zone, not a marketing stat.
Beneficial flora takes the zone around the root and leaves no room for pathogens like Pythium or Fusarium. Less damping-off on seedlings, fewer mold issues in the clone dome.
Mycorrhizae extend the root's reach many times over — as if the plant got a second, much larger root system. They break down organic matter and deliver phosphorus, nitrogen and micronutrients in exchange for sugars from photosynthesis.
Beneficial bacteria in the root zone produce natural growth and rooting hormones (auxins, cytokinins). They do the job you normally pay for in bottled root stimulants and rooting hormones.
Facts from the label
Parameters you can line up against the tech sheet of any competitor.
The ingredient list is deliberately short — every component has one clearly defined job. Nothing for filler, nothing for weight.
The retention base — holds water and nutrients without compacting. Peat stabilizes the structure, black earth delivers cation exchange capacity (CEC).
Aeration and drainage. The root gets oxygen, excess water moves down instead of drowning the root system. No rot.
The heart of the ecosystem. Slow-release NPK + humus + enzymes + living microbes. This is where the 14 days of autopilot come from.
400+ strains: arbuscular mycorrhizae, Trichoderma, Bacillus, PGPR. A consortium, not a single species for the front of the bag.
Who it's for
Low starting EC, pH 6.0–7.0, heavily aerated structure — Biostart is neutral on purpose. The same bag handles photoperiods, autos, fasts and regs for breeding — and after hours, the tomatoes on the balcony and the monstera in the living room. No recipe change, no two different bags on the shelf.
Long veg and long flower — this is where a stable base matters most. Biostart keeps pH in range through the whole run, so in week 4–5 of flower the plant doesn't stop taking up phosphorus and potassium (the classic P-K lockout). 25% worm castings add humus and micronutrients that a purely mineral program — Athena or Terra Aquatica — by design doesn't carry.
A 9–11 week cycle from seedling to harvest doesn't forgive stress. Low starting EC protects the fresh seedling, and 14 days of autopilot on worm castings cover the full veg — what enters flower is a plant, not a runt. You run the whole cycle in one bag, no transplanting.
Mother plants sit in the same pot for months — they need a base that doesn't collapse after six weeks. Living microbiology keeps the roots in shape long-term, and mycorrhizae (fungi that partner with the root) help pull phosphorus and micronutrients. Clones land in gentle, low EC with no risk of burning the fresh root.
Tomatoes, peppers, chilies, strawberries, basil, mint, monsteras, philodendrons. Same base — different plants. Growroom owners run Biostart in parallel for the balcony veg patch — why keep two different bags.
Honest comparison
Plagron (Batmix, All-Mix, Royalmix), BioBizz (All-Mix, Light-Mix) and Canna (Terra Pro, Coco Pro) are well-proven, mass-produced all-mixes — universal, widely available, predictable. Biostart is a different take on the base: small-batch production, hand calibration, a deliberately narrow target (the craft grower who already knows what they want). You're not replacing one with the other — you're picking a different starting point.

In practice
A seedling or clone goes into Biostart. You pour water at pH 6.0–6.5, EC 0.2–0.4. The root finds mycorrhizae within 5–7 days and starts spreading wide through the aerated structure. No feeding, no stress. Thick stem, short internodes — because what happens under the soil shows up above it immediately.
The worm-casting reserve starts thinning out, but the soil is already colonized. You roll in with your program — Athena Pro Line, Terra Aquatica TriPart, Plagron Terra Grow, BioBizz Bio-Grow, Canna Terra Vega or organic teas. The microbiology turns all of that into forms the root can take up directly.
Stable pH keeps the plant clear of phosphorus and potassium lockouts. The microbial flora keeps breaking down organic feeds into forms the root actually absorbs. Result: more sugars, fuller terpenes, more final mass out of the same feeding.
FAQ
Scale and calibration. Plagron and BioBizz are well-proven mass-market mixes engineered for a broad market. We run Biostart in small, craft batches — recipe hand-calibrated, feed profile deliberately sitting between Light-Mix (too empty on day one) and Batmix (too hot under clones). Plus 25% worm castings and living microbiology, which together act as a starter buffer — instead of the classic bottled starter.
No. For the first ~14 days, 25% worm castings + the microbiology cover everything. You pour water at pH 6.0–6.5. No root stimulants, no bottled humic acids, no boosters — and that's exactly where the real savings are compared to starting on Light-Mix.
Yes — and that's the whole point. Biostart is a base, not a competitor to any feeding line. From day 14 on you come in exactly on your regular schedule: Athena Pro Line (Core + Grow/Bloom) or Blended, Terra Aquatica TriPart (FloraMicro / Gro / Bloom), Plagron Terra Grow/Bloom, BioBizz Bio-Grow/Bloom, Canna Terra Vega/Flores, a topdress or an organic tea. The worm-casting buffer and living microbiology stabilize pH and break down organic inputs — especially under heavy mineral programs like Athena, where a stable base translates to fewer lockouts and fewer emergency root-zone flushes.
pH measured in a water extract sits in 6.0–7.0, typically close to 6.5 — the sweet spot for most vegetables, herbs and cannabis. Starting EC is low (around 1.0–1.5 mS/cm, depending on batch), so it's safe for seedlings and fresh clones. Full spec ships with the batch.
Distribution runs directly through Nash Growshop (Český Těšín) and a handful of hand-picked retail partners. We work in small batches to keep the microbiology in good shape — we don't produce six months ahead. If you're coming to Konopex 2026, drop by the booth.
If you want to see how a small-batch soil base behaves under your regular feeding program — write. The first thing you'll see after two weeks is a dense, white root system. The rest of the cycle is just a consequence of what happens underground. Direct orders ship from the current batch.
