Spore Syringes
by Mondo
The Mondo Treasure Coast spore syringe is a 20ml syringe loaded with Psilocybe cubensis spores from one of Florida's most storied strains. Named after the stretch of coastline famous for Spanish shipwrecks and lost gold, Treasure Coast cubensis has earned its reputation among home cultivators for reliable colonisation, generous yields, and a genuine wildcard: some specimens develop near-albino phenotypes that are noticeably more potent than their standard siblings. This Mondo syringe gives you everything you need to inoculate your substrate and start a grow from scratch.
Treasure Coast cubensis is a strain that keeps things interesting. Most flushes produce fairly standard-looking cubensis fruit bodies — golden-brown caps, sturdy stems, nothing out of the ordinary. But here's where it gets good: this strain has a documented tendency to throw near-albino specimens. These pale, almost ghostly mushrooms aren't just a visual curiosity — growers consistently report that the albino phenotypes come through stronger than the regular ones. Whether you can nudge the genetics in that direction through environmental tweaks remains unclear, so there's a genuine element of surprise each time you fruit.
We've been selling Mondo products for years, and Treasure Coast sits comfortably in the top tier for growers who want solid results without a steep learning curve. It colonises fast, fruits reliably, and delivers multiple flushes. If you've already grown a Golden Teacher or B+ and want something with a bit more personality, this is a natural next step.

A spore syringe needs a substrate to work with. Pair this Treasure Coast syringe with a Mondo grow kit for a complete setup — the substrate comes pre-colonised in the kits, but if you're going the full DIY route with grain jars, grab a pressure cooker and some grain spawn bags. A heating mat with thermostat is also worth picking up if your room temperature drops below 28°C, since hitting that colonisation sweet spot of 28–30°C makes a real difference to speed.
Grow kits are brilliant if you want mushrooms in 2–3 weeks with minimal effort. The substrate is already colonised — you just add water and wait. A spore syringe, on the other hand, puts you at the very beginning of the process. You're inoculating sterile grain or substrate yourself, watching the mycelium spread, and managing the full lifecycle. It takes longer (add 14–18 days for colonisation before you even start fruiting), but you learn far more about the organism you're working with.
The practical advantage? A single 20ml syringe can inoculate multiple jars or bags. Mondo recommends roughly 3–5ml per litre of substrate, so you can stretch one syringe across several containers and run a larger operation than a single grow kit allows. You also get to work with grain spawn, which many experienced growers prefer for its faster colonisation and better contamination resistance once fully colonised.
The honest limitation: contamination risk is higher when you're doing your own inoculation. One ungloved finger, one unsterilised surface, and you've introduced competing moulds that can wipe out a jar. A still air box or flow hood, proper gloves, and a flame-sterilised needle aren't optional — they're the difference between a successful grow and a bin full of green mould. If you're not ready for that level of sterile technique, a pre-colonised grow kit is the smarter call.
The near-albino thing isn't marketing fluff — we've seen photos from customers who've pulled entirely white fruits from Treasure Coast grows. It doesn't happen every time, and there's no reliable trick to force it. Some growers swear that cooler fruiting temperatures (closer to 23°C than 27°C) increase the odds, but honestly, we can't confirm that. It might be purely genetic lottery. Either way, the standard phenotype still produces a very respectable cubensis mushroom, so you're not losing out if your batch comes through golden-brown.
One thing we will say: Treasure Coast tends to produce a lot of smaller mushrooms rather than a few massive ones. The overall yield by weight is very good — you just get more individual fruits per flush. Some growers prefer that; others want fewer, chunkier specimens. If you're in the latter camp, have a look at the Mondo B+ or McKennaii spore syringes for comparison.
At the recommended 3–5ml per litre of substrate, a single 20ml syringe covers roughly 4–6 jars. That's enough for a solid multi-container grow from one purchase.
If you're preparing your own grain substrate, yes — sterilising grain requires a pressure cooker running at 15 PSI for 60–90 minutes. Pre-sterilised grain bags skip this step entirely and are a good option if you don't own one.
Keep it in the fridge at 2–8°C, sealed in its sterile packaging. Stored this way, Mondo spore syringes remain viable for months. Don't freeze them — ice crystals can damage the spores.
Both contain spores in a liquid solution. Spore vials typically have a self-healing injection port and a slightly longer shelf life, but syringes are simpler to use — you just attach the needle and inject. For most home growers, the syringe is the more practical choice.
Near-albino phenotypes do appear in Treasure Coast grows, but it's not guaranteed. The strain carries the genetic potential, and some grows produce strikingly pale specimens. Treat it as a bonus rather than an expectation.
The substrate should be entirely covered in white mycelium with no visible bare grain. If you see any uncolonised patches, give it a few more days. Rushing to fruiting with incomplete colonisation invites contamination.
Airborne mould spores landing on your substrate during injection. A still air box reduces this risk dramatically. Flame-sterilise your needle, wipe ports with alcohol, and work quickly. Most contamination happens because of skipped sterile steps, not bad genetics.
