# Best mushroom growing kits for kids and classrooms Source: https://spawnrun.com/best/best-mushroom-grow-kit-for-kids Publisher: Spawn Run. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://spawnrun.com/how-we-pick A mushroom growing kit works as a project for kids when something visibly changes every day and the daily job is small. A box kit holds a block the mushroom has already grown through: once it is opened, the child mists it and watches for pins, the first tiny mushrooms, which grow into a full cluster within days. Oyster kits are the usual pick because they are the quickest, and the sellers here state a first harvest in about 7 to 10 days at the fastest. What differs between kits is the species, how fast the seller says it fruits, what the daily care is and whether a second flush (a repeat crop) is mentioned. This guide compares six kits on those points using only what each listing states; none was grown for this page. None of these listings states a recommended age, so none is given here. An adult opens the box, makes any cut in the bag and handles the harvest knife, and the mushrooms are cooked before eating. ## Picks ### 1. North Spore Organic Lion's Mane Mushroom Grow Kit, Spray & Grow, 4 lbs Species: Lion's mane; First harvest: As little as 7 days; Daily care: Mist once or twice daily; Flushes: Several flushes possible A 4 lb block that ships fully colonized in a box with a perforated front panel and a spray bottle. Its listing gives the most complete numbers here, which suits a first-time grower who wants to know what to expect. What the listing offers: - Ships fully colonized and ready to fruit: remove the perforated front panel and mist once or twice daily with the included spray bottle. - The listing states a first flush in as little as 7 days at 0.5 to 1.5 lb, with several flushes possible with continued care. - USDA Certified Organic and non-GMO, handmade in Maine, with detailed growing instructions and a stated guarantee to grow. Limits to know: - No humidity tent or dome is listed in the box, so a dry room may call for a loose plastic bag with holes over the block. - The substrate is described only as organic; the listing does not say whether it is sawdust, soy hulls or a mix. ### 2. North Spore Blue Oyster Mushroom Grow Kit, Organic, Spray & Grow, 4 lbs Variety: Blue oyster; Block weight: 4 lb; First harvest: As little as 7 days; Flushes: Second flush, sometimes more A 4 lb blue oyster block in a box with a perforated panel and a spray bottle.

What the listing offers: - Stated routine is one job a day: mist with the included spray bottle once the perforated panel is removed. - Listing says most kits produce a second flush with continued misting, which gives the project a second round. - Detailed growing instructions are included in the box, and the kit weight is stated: 4 lb. Limits to know: - As little as 7 days is the fastest case; the listing gives no typical range for this kit. - No age guidance and no temperature range in the listing; blue oyster is a cool-room variety (55 to 75 F). ### 3.
