The best magic mushroom grow kits compared: which should you buy?

Across the 17 kits the spread is narrower than it looks. Every kit grows Psilocybe cubensis. The eight classic kits share a 1200 ml cake and are rated 300–600 g of fresh mushrooms over three flushes, with Treasure Coast starting higher at 400–600 g and Mazatapec the one kit running to a fourth flush. The nine Ready-2-Grow bags are rated 150–500 g and vary far more in flush count — three for most, two for Enigma and MVP, and a single flush for APE and the McKennaii bag. First harvest lands two to four weeks after setup everywhere but one: most kits are rated two to three weeks, the classic McKennaii can be ready from week one, and the Enigma bag is the outlier at around eight weeks. Difficulty is 1 out of 5 for twelve of the seventeen kits; only the classic McKennaii (4/5) and Treasure Coast (3/5) ask for real attention. Potency ratings run from 1 out of 5 on the Hillbilly Pumpkin bag to 5 out of 5 on McKennaii, Enigma and APE.

If this is your first grow, difficulty matters more than potency or yield. Twelve of the seventeen kits are rated 1 out of 5: no sterile work, no extra equipment, and a routine that comes down to misting, fresh air and patience. Among the classic kits, Golden Teacher, B+, Cambodia and Mexican all sit at 1/5 and are rated 300–600 g of fresh mushrooms over three flushes, with a first harvest two to three weeks after setup. Among the Ready-2-Grow bags, Hillbilly Pumpkin pairs that same 1/5 difficulty with the mildest potency rating in the range, 1 out of 5. The one kit we keep away from first-timers is the classic McKennaii, at 4 out of 5: the chooser above hides it completely from anyone who answers "first grow", because it punishes a missed step. Treasure Coast (3/5) still appears, but treat it as a step up rather than a starter kit.

For a first grow, a 1/5 classic kit such as Golden Teacher is the safest start: 300–600 g fresh over three flushes, first harvest in two to three weeks, and nothing to sterilise.

Four kits carry the top potency rating of 5 out of 5: the classic McKennaii kit and the Ready-2-Grow bags Enigma, APE and McKennaii. Potency here is a comparative strain rating drawn from breeder specifications and our own catalogue data, not a laboratory measurement, and it is not dosing guidance. Difficulty separates the four sharply: the classic McKennaii is the most demanding kit we carry at 4 out of 5, while the McKennaii and APE bags are rated 1 out of 5, because the bag format handles the difficult part for you. The trade-off is flush count — APE and the McKennaii bag are rated for a single flush and Enigma for two, against three for the classic McKennaii kit.

For top potency with the least room for error, the 5/5 Ready-2-Grow bags — McKennaii and APE — pair the highest potency rating with 1/5 difficulty; the classic McKennaii kit matches them on potency but asks for 4/5 skill and rewards it with three flushes.

The classic 1200 ml kits are the yield leaders: all eight are rated 300–600 g of fresh mushrooms across three to four flushes, and Treasure Coast has the highest floor at 400–600 g. Mazatapec is the endurance pick, the only kit rated for a fourth flush, which spreads the same cake over a longer run. Ready-2-Grow bags trade top-end weight for simplicity: 150–500 g depending on the strain, with MVP at 300–500 g and Jack Rabbit, the Golden Teacher bag and the McKennaii bag at 200–500 g leading the bag range. One number to keep in mind: fresh weight is not dried weight. Mushrooms are mostly water, and drying removes the large majority of it, so a 600 g fresh harvest is a far smaller figure once dry.

For the biggest harvest, take a classic 1200 ml kit: 300–600 g fresh over three to four flushes, with Treasure Coast starting from 400 g and Mazatapec the only kit rated for a fourth flush.

The choice comes down to yield versus handling. A classic Azarius kit is a 1200 ml colonised cake with a grow bag; it is rated for more fresh weight per kit (300–600 g over three flushes) and it is the format most grow guides are written for. A Ready-2-Grow bag is self-contained: you open it, mist it and close it again, with no separate grow bag to set up and less room for a handling error. Bags are rated 150–500 g and several stop after one or two flushes — APE and the McKennaii bag are rated for a single flush, Enigma and MVP for two. Bags also carry strains the classic line doesn't, including APE, Enigma, Jedi Mind Fuck and Makilla Gorilla. Timing is close either way: classic kits are rated two to three weeks to first harvest, or from week one for the classic McKennaii, and bags two to four, with Makilla Gorilla and APE running longest and the Enigma bag the one outlier at around eight weeks.

Choose a classic 1200 ml kit for maximum fresh weight over three flushes; choose a Ready-2-Grow bag for the simplest handling and for strains such as APE, Enigma and Makilla Gorilla that the classic line doesn't carry.

Every number on this page comes from the specification we hold for each kit — difficulty, potency, expected fresh yield, flush count, time to first harvest and substrate size — checked by hand and dated in the byline with this section. Ranking is fit-based: the chooser scores each kit against the answers you give, so the top pick changes when your answers change, and no kit is promoted for being ours. Where two kits score exactly the same, the Azarius-branded kit is listed first; that tie-break never overrides a difference in score. Out-of-stock kits are never ranked above kits you can actually order, and kits we can't ship to your country are left out of the ranking entirely.

Grow kit legality varies from country to country, and so do the rules on what may cross a border. We only ship grow kits to countries where we can lawfully deliver them, so which kits you can order always depends on your delivery address. You must be 18 or older to order, and checking the rules that apply where you live is your responsibility.
