Grow kits
by Azarius
The Treasure Coast grow kit is a fully colonised Psilocybe cubensis cultivation kit that produces dense, heavy-capped mushrooms across multiple flushes — with combined fresh yields that can exceed 400 grams. Azarius developed this exclusive kit around a Florida-origin strain that sits in a sweet spot: moderate-to-strong potency, vigorous colonisation, and a forgiving growth habit that doesn't punish small mistakes. If you've grown a Golden Teacher kit before and want something with a bit more weight behind it, this is the next step up.
The Treasure Coast strain originally came from wild specimens found along Florida's Atlantic coastline. Over the years, cultivators stabilised those genetics into something reliable and vigorous — a strain that colonises fast, fruits in thick clusters, and produces caps noticeably larger than average cubensis varieties. You'll see the difference when you open the fruiting chamber: where something like a Thai or Cambodian strain tends to throw up lots of thin, leggy pins, Treasure Coast pushes out fewer but chunkier fruits with broad, fleshy caps.
Azarius packages this strain as a fully colonised rye-grain cake with a perlite and vermiculite casing layer already in place. The mycelium network is established before the kit leaves the warehouse, so there's no inoculation, no waiting weeks for colonisation, and no sterile technique required on your end. You add water, maintain humidity, and wait. First pins typically appear within 7–14 days of setup.
One honest note: Treasure Coast can be slightly slower to pin than Golden Teacher or B+. We've seen kits take the full two weeks before showing any signs of life. Don't panic and don't start poking at the cake — patience pays off with this strain, and the yield per flush tends to be heavier than faster-pinning varieties.

We get this question constantly. The Golden Teacher is the world's best-selling cubensis strain for a reason — it's fast, forgiving, and the effects are gentle enough for a first experience. Treasure Coast is a step sideways rather than straight up: similar difficulty level, but the fruits are physically bigger, the clusters are denser, and the potency sits a notch higher. If Golden Teacher is a reliable hatchback, Treasure Coast is the estate version — same engine, more cargo space.
| Feature | Treasure Coast | Golden Teacher |
|---|---|---|
| Potency | Moderate to strong | Moderate |
| Time to first pins | 7–14 days | 5–10 days |
| Fruit size | Large caps, dense clusters | Medium caps, even spread |
| Total yield (fresh) | 400g+ | 300–400g |
| Best for | Growers wanting heavier individual fruits | First-time growers wanting speed |
| Forgiveness level | High | Very high |
Start with Golden Teacher if you've never grown before and want the fastest possible result. Go with Treasure Coast if you've done one grow already and want something with a bit more physical presence in the fruiting chamber — the clusters genuinely look impressive.
Complete your setup with a Thermo/Hygrometer to keep temperature and humidity dialled in during fruiting. If you're planning to dry your harvest, a Food Dehydrator makes the difference between cracker-dry mushrooms and a soggy mess that won't store properly.
The Treasure Coast grow kit arrives fully colonised, so the hard work is already done. Your job is humidity, temperature, and patience. Here's the process from box to harvest:
The first thing you notice about Treasure Coast fruits is the cap size. Where many cubensis strains produce caps the size of a two-pound coin, Treasure Coast regularly throws caps that span 5–7cm across — sometimes wider. The stems are thick and meaty, often with a slight bluish bruising at the base (that's oxidised psilocin, completely normal). Clusters tend to be tight, with 3–8 fruits growing from a single point on the cake.
Colour-wise, expect golden-brown caps that lighten toward the edges, with off-white to pale yellow stems. The flesh has a dense, slightly rubbery texture when fresh — noticeably heavier than the same volume of a thinner-stemmed strain. Dried, they shrink to about 10% of their fresh weight, which is standard for cubensis.
The 400g+ yield figure is achievable across three flushes under good conditions. Your first flush will typically be the largest — around 150–200g fresh. Second flush often matches or slightly exceeds the first. Third flush drops off but still adds meaningful weight. We've seen growers squeeze out a fourth flush, but the returns diminish sharply and contamination risk rises with each cycle.
After selling grow kits since 1999, we can predict the support emails almost to the day. Day 3: "Nothing's happening, is it broken?" Day 7: "I see white fuzz — is that mould?" Day 10: "There are tiny pins everywhere!" The white fuzz is almost always healthy mycelium reaching up through the casing layer. Actual contamination is green, black, or bright orange — and it smells off. If your kit smells like fresh mushrooms and forest floor, you're fine.
The single most common mistake we see with Treasure Coast specifically is harvesting too late. Because the caps grow large, people assume they need to wait until they're fully flat. By that point, the mushroom has already dropped its spores, which coat the cake surface in a dark purple-black layer. That spore layer doesn't kill the kit, but it can reduce yields on subsequent flushes. Harvest when the veil beneath the cap starts to tear — that's the sweet spot between maximum weight and maximum potency.
Expect 7–14 days for pins to appear after soaking, then another 5–7 days for those pins to reach harvestable size. Total time from opening the box to first harvest is typically 2–3 weeks. Treasure Coast can be a few days slower than Golden Teacher, so don't rush it.
Under good conditions, the combined fresh yield across up to three flushes can exceed 400 grams. First flush usually accounts for 150–200g, with the second flush often close behind. Dried weight is roughly 10% of fresh — so around 40g+ total.
No. The Treasure Coast grow kit arrives fully colonised with an established mycelium network. There's no inoculation step and no need for a still air box or pressure cooker. Clean hands and a wiped-down surface are enough. The substrate is ready to fruit straight out of the box.
Aim for 21–24°C during fruiting. Below 18°C and growth slows dramatically; above 28°C and you risk bacterial contamination. A consistent room temperature is better than fluctuating between extremes. Keep it away from radiators and direct sunlight.
Sometimes, yes — we've seen growers get a fourth flush. But yields drop off steeply after the third, and each additional soak cycle increases contamination risk. Three solid flushes is the realistic target. After that, the substrate is largely spent.
Keep the sealed, unopened kit in the fridge at 2–8°C. It stays viable for about two weeks refrigerated. Don't freeze it — ice crystals destroy the mycelium. The sooner you start it, the better the results.
Yes. It's slightly slower to pin than Golden Teacher or B+, but the growing process is identical and the strain is forgiving of minor humidity or temperature fluctuations. If you can follow the 10 steps above and resist the urge to open the bag every hour, you'll do fine.
Blue bruising is oxidised psilocin — it happens when the flesh is handled, bumped, or exposed to air. It's completely normal and actually a reliable indicator that the mushrooms contain active compounds. It doesn't mean they're damaged or contaminated.
