Availability: In stock
Mac Galactic is the fast one. Where Jack Frost makes you wait weeks, this strain colonises aggressively and throws its first pins in as little as two weeks. It's a cross between Jedi Mind Fuck and Melmac — two strains known for speed and size respectively — and the combination delivers exactly what you'd expect: dense canopies, thick stems, and a potency rating that puts it above most cubensis in the catalogue.
Part of the Cloud920® Genetic Series — Hybrid Fusion
Origin & Genetics
Mac Galactic was originally isolated by Eric Burden of Denver Spore Company as a cross between JMF (Jedi Mind Fuck) and Melmac. Eric selected for a balance of size, potency, and consistency — and then Full Canopy Genetics took it further, refining the isolation for canopy density and biological efficiency. From JMF it inherits its aggressive colonisation speed and reliable flush potential. From Melmac — a strain loved for its massive, phallic fruit bodies and above-average potency — it inherits its sheer size and thick-stemmed morphology. The result is a strain that never drops spores, consistently produces large canopies, and rivals some of the strongest cubensis available.
Why Choose Mac Galactic?
- Strength: ★★★★★☆ (5/6) — high potency that rivals many 6/6 strains. Full Canopy Genetics describes its alkaloid content as "incredibly potent." Not one to underestimate.
- Fast and aggressive — first pins typically appear within 14–21 days. One of the quickest strains in the Cloud920 range.
- Thick, dense flushes — large fruit bodies with caps up to 8 cm and heavy stems. Expect 400–800g fresh across multiple flushes.
- Documented pedigree — created by Eric Burden (Denver Spore Company), refined by Full Canopy Genetics. Traceable genetics, no guesswork.
What's in the Box
- 1x Cloud920 Grow Bag — 2000cc pre-colonised substrate with active Mac Galactic mycelium. Integrated micron filters provide passive air exchange and contamination protection.
- 1x Large bag clip — to seal the bag securely between ventilation sessions.

How the Cloud920 Grow Bag Works
- Open once — fold the bag open in a clean space to allow fresh air in and trigger pinning.
- Place and wait — put the bag in indirect light at 23°C. No soaking, no misting required in the first phase.
- Air daily from week 2 — briefly open and refold the bag once a day to encourage pin development.
- Harvest and repeat — twist and pull mushrooms at the base before caps open fully. Rehydrate and repeat for additional flushes.
