Sol-Mak Liquid Culture Syringe – Cloud920

About the Sol-Mak liquid culture

The Sol-Mak liquid culture — also spelled Solmac or Sol Mac — is a Hybrid Fusion isolate of Psilocybe cubensis, best known for its distinctive split-cap morphology that opens into segments resembling sun rays. Cloud920 classifies it within its Hybrid Fusion Series, reserved for modern, purpose-bred cubensis cultivars with defined breeder provenance.

Origin and history of the Sol-Mak strain

Sol-Mak is a hybrid cross between Melmak — a Penis Envy variation from the Homestead lineage — and the Sol cultivar, giving the strain its combined name and its blend of Melmac vigour with a distinctive sun-like cap trait. An alternate account describes Sol-Mak as a direct Melmac isolation by the mycologist Nichy Myco, taken from a Melmak OG fruiting body that exhibited the split-cap phenotype. Both accounts agree that the Melmac (Penis Envy) side of the lineage dominates the growth behaviour: thick meaty stems, prominent blue bruising and above-average potency. The lineage chain runs Amazonian P. cubensis (McKenna, ~1971) → Penis Envy (Guitierrez, ~1975–78) → Melmak (Homestead PE) → Sol-Mak.

Cloud920 works with a selected isolate propagated on agar and stepped up through liquid culture in a lab-controlled environment, so the split-cap phenotype and rapid colonisation traits stay consistent from syringe to syringe.

What makes this Sol-Mak culture distinctive

Three traits set Sol-Mak apart from other Hybrid Fusion cubensis isolates: the diagnostic split-cap trait where mature caps open into wedge-shaped segments resembling sun rays, the thick, meaty stems typical of the Melmac heritage, and prominent deep-blue bruising that indicates high alkaloid content on contact or damage. Cap colour is caramel to golden-brown, stem colour ranges from white to yellowish, and the spore print is dark purple-brown. Colonisation is fast — 10–14 days per community reports — a marked difference from other Melmac-lineage cultivars. Growers who want a slower, more classic Penis Envy comparison can look at Cloud920's Penis Envy liquid culture; those who want another Melmac descendant can compare with Melmac Monster liquid culture from the same Series.

Sol-Mak potency profile

No independent Oakland Hyphae or peer-reviewed potency data has been published for Sol-Mak as of research date. Vendor-reported figures place psilocybin around 10 mg/g dry weight — a high figure consistent with Melmac-lineage expectations, though not lab-verified. The Shroomery consensus is that most measured differences between cubensis cultures fall within normal genetic variance, with substrate, harvest timing and drying method driving more of the final potency than the strain label.

What you receive in your Cloud920 syringe

You receive one 10cc syringe of Cloud920 Sol-Mak mycelium, packaged with a separately sealed sterile needle. The syringe contains QC-verified mycelium suspended in Cloud920's nutrient broth, produced in a lab-controlled environment with viability, sterility and morphology checks on every batch.

How to inoculate with this liquid culture

Cloud920 recommends 2-3 cc per small grain bag, 3-4 cc per medium bag and 4-5 cc per large bag. Flame-sterilise the needle before injection and work in a still-air box or under laminar flow, wiping the injection port with 70% isopropanol before and after. Sol-Mak is a fast coloniser: expect visible mycelial growth within 3–7 days at 22–27 °C, with full grain colonisation completing in 10–14 days under stable conditions. Fruit at 21–24 °C and 85–95% relative humidity. Store the syringe cool, dark and upright, and use within the shelf life printed on the label.

Microscopy and research use only

This Sol-Mak liquid culture is sold for microscopy and mycological research. Cultivation of psilocybin-producing fungi is regulated or prohibited in many jurisdictions — verify your local legislation before use.

Frequently asked questions

How long does the Sol-Mak liquid culture take to colonize?
With Cloud920's nutrient broth, visible mycelial growth typically appears within 3–7 days. Full grain colonization completes in roughly 10–14 days under stable conditions at 22–27 °C — noticeably faster than most Penis Envy-descended cultivars.

What is the split-cap trait?
Mature Sol-Mak caps open into wedge-shaped segments arranged like sun rays — the defining morphological trait that gave the cultivar its name. It is a reproducible feature of the Melmak × Sol cross and is not a sign of stress or contamination.

How should I store this Cloud920 syringe?
Refrigerate at 2–8 °C, upright, in the original sleeve. Keep away from direct light and freezing temperatures. Use within the shelf life printed on the label.

Is this Cloud920 Sol-Mak culture lab-verified?
Yes. Every Cloud920 batch is produced in a lab-controlled environment with QC verification on viability, sterility and morphology before the syringe is filled and sealed.
