Description
Build Your Own Ecosphere lets you put together the mushroom grow tent you actually need. Every build starts with a 4-tier or 5-tier Ecosphere 3.0 Foundation Edition: the greenhouse tent, a 3L Monsoon ultrasonic humidifier, COB LED lighting, two timers, a drip liner and a Bluetooth thermometer/hygrometer. From there you add only what your grow calls for: heat, humidity control, fresh air, extra shelf space, and the grain, substrate or fruiting kits you plan to run.
The more you add, the more you save. 3–4 items take 5% off, 5–6 items take 10% off, and 7 or more take 15% off everything in your build, the tent included.

An Ecosphere Foundation Edition tent with mushrooms fruiting on every shelf.

The Foundation Edition: tent, humidifier, lighting, liner, timers and filter disks.
Heat is not included with the tent. The Foundation Edition holds humidity and light, but the tent sits at your room temperature. If your room runs cool, add the heater unit in step 2.
Choosing your tent size
| Tent | Height | Growing space | Footprint |
|---|---|---|---|
| 4-Tier Foundation Edition | 63" | 17.7 cu ft | 29" x 20" with drip liner |
| 5-Tier Foundation Edition | 75" | 22.5 cu ft | 29" x 20" with drip liner |
Both sizes use the same floor space, humidifier and lighting. If your ceiling height allows, the 5-tier gives you an extra full shelf.
Climate control add-ons
| Add-on | What it is | Add it if |
|---|---|---|
| Heater Unit with Digital Temperature Controller | 200W light-free infrared heater with a 5" brushless circulation fan and lava rock tray, plus a thermostat with a 6 ft waterproof probe | Your room runs cooler than your mushrooms' fruiting range |
| Digital Humidity Controller | Runs the included humidifier by the actual humidity reading instead of by the clock | You want humidity held at a set point |
| Fresh Air Amplifier Fan Unit | 4" brushless fan with a speed dial and a washable 6" x 4" filter vent | You grow high-oxygen species like oysters and lion's mane, or run a fully loaded tent |

A 4-tier tent with aluminum trays fruiting, the heater unit on the bottom rack and the humidifier beside the tent.
The heater does not control humidity. Its lava rock tray adds some moisture as it warms, like water on sauna stones, but the humidifier that comes with your tent does the work of reaching 80–90% humidity. The heater unit sits on the bottom rack.
Capacity add-ons
- Heavy Duty Aluminum Trays (6-pack): 18" x 13.4" x 2.7" trays for bulk casing grows. Two fit on each shelf.
- 5th/6th Tier Attic Shelf: an extra shelf with support poles that adds a tier to the top of the frame, with tool-free installation.
Grow supplies
Bulk growing: grain first, then substrate
- Grain spawn bags (2-packs): Original Rye or Premium 5-Grain, sterilized in-house with a self-healing injection port.
- 32oz grain jars (3-packs): Original Rye or Premium Quick-Colonizing 5-Grain.
- Bulk substrate (5 lb bags): Midwest's Select Bulk Substrate, Black Cow or Willy's Blend, pasteurized and ready to use.
Grow YOUR way!
- 5 lb mushroom grow kits: ready-to-fruit blocks including Lion's Mane, Shiitake, Blue Oyster, Pink Oyster, King Trumpet, Chestnut, Maitake, Reishi, Turkey Tail and more.
- All-in-one grow bags: the 4 lb and XL 6 lb bags for manure-loving mushrooms, and the XL 6 lb Wood Lover's kit.
- Sterilized Master's Mix (5 lb bag): hardwood and soy hull substrate for wood-loving gourmet species.
- Trays: Great for all types of dung & manure loving varieties. Grow two trays per shelf!
You provide: a spore syringe or liquid culture syringe for grain spawn bags, grain jars and the manure-lover all-in-one bags. The 5 lb grow kits arrive colonized and ready to fruit. Shop liquid culture syringes, or use our syringe calculator to see how many you need.
Harvest and lab extras

FAQ
What comes with the tent?
Every build starts with an Ecosphere 3.0 Foundation Edition: the 4-tier or 5-tier greenhouse tent and frame, a 3L Monsoon ultrasonic humidifier, 16.4 ft of COB LED lighting, two 24-hour timers, a Bluetooth thermometer/hygrometer, an 8mm drip liner, 10 filter disks and a setup guide.
How do the bundle savings work?
The discount is based on how many items are in your build, and the tent counts as one. 3–4 items take 5% off, 5–6 items take 10% off, and 7 or more take 15% off everything. The savings show automatically as you add items.
Can I use a coupon code on this bundle?
No. Bundle savings are already applied to your price, so this bundle can't be combined with coupon codes or other discounts.
Do I need the heater?
Only if your room runs cooler than your mushrooms' fruiting range. The tent holds humidity and light but sits at room temperature. The heater unit adds a 200W infrared heater, a circulation fan and a digital temperature controller that switches it on and off to hold your set point.
Does the heater control humidity?
No. Its lava rock tray adds some moisture as it warms, but it does not control humidity. The 3L Monsoon humidifier that comes with your tent handles humidity on a timer, and the optional digital humidity controller runs it by the actual humidity reading instead.
Should I choose the 4-tier or the 5-tier tent?
Both use the same 29 x 20 inch footprint, humidifier and lighting. The 4-tier is 63 inches tall with 17.7 cubic feet of growing space; the 5-tier is 75 inches tall with 22.5 cubic feet and an extra full shelf. If ceiling height allows, the 5-tier gives you the most room for the same floor space.
What do I need to add to start growing?
That depends on what you pick. The 5 lb mushroom grow kits arrive colonized and ready to fruit. Grain spawn bags, grain jars and the manure-lover all-in-one bags need a spore syringe or liquid culture syringe, which is sold separately.
What can I grow in an Ecosphere?
Oysters, lion's mane, shiitake, chestnut, cordyceps and more. The shelves hold jars, spawn bags, fruiting blocks, monotubs and casing trays, and it is common to run several species at once.
How is this different from the Mushroom Ecosphere 3.0?
The Mushroom Ecosphere 3.0 is a fixed kit: the tent with the infrared climate control unit, thermostat and two aluminum trays included. Build Your Own starts from the Foundation Edition tent and lets you choose which climate control, capacity and grow supplies go with it.
