What comes in the Foundation Edition?

The 4-tier greenhouse, a 3-liter Monsoon humidifier, a 16-foot COB LED strip set, 10 polyfil filter disks, and a Bluetooth thermometer/hygrometer. Jars, spawn, and substrate are not included.

How many jars or bags fit?

Up to 96 jars, 20 spawn bags, or 5 casing trays, depending on how you arrange the four adjustable tiers.

No fan is included. The filter disks allow passive air exchange, but many growers add a small fan for better fresh-air movement.

Can I control humidity automatically?

The Monsoon humidifier runs on its own controls, not from the Bluetooth sensor. You adjust it manually based on the readings.

How much room does it need?

The greenhouse is about 29 by 20 by 63.5 inches, so plan for a corner with roughly 5 feet of height and access to a power outlet.

Is it good for a first grow?

Yes, if you want the climate gear bundled. If you already own a humidifier and lights, a plain greenhouse tent gives you the same space for less.

Our take on the Midwest Grow Kits Mushroom Ecosphere 3.0 Foundation Edition 4-Tier

The Ecosphere 3.0 Foundation Edition is a complete indoor mushroom-growing setup built around a 4-tier greenhouse measuring about 29 by 20 by 63.5 inches, giving roughly 17.7 cubic feet of interior space. It bundles the pieces most beginners would otherwise buy separately: a 3-liter Monsoon humidifier, a 16-foot COB LED strip set, a Bluetooth thermometer and hygrometer, and peel-and-stick polyfil filter disks for air exchange. Capacity is generous for a home kit, with room for up to 96 jars, 20 spawn bags, or 5 casing trays across the adjustable tiers. It suits people who want one box with the climate gear sorted, though growers who already own a humidifier or lights will pay for parts they don't need.

What reviewers say

Owners of Midwest Grow Kits setups generally describe the Ecosphere as a convenient all-in-one starting point, with the bundled humidifier and lights doing most of the work. The recurring complaints are humidity escaping from the tent and the humidifier needing frequent refills.
