Description
The Ecosphere replacement tent cover restores a torn, cloudy or brittle greenhouse cover in a few minutes. It is an upgraded, thicker 10 mil crystal-clear cover that zips over your existing 4-tier or 5-tier Ecosphere or Martha tent frame, holding humidity in and letting light through.

Why replace your cover
- Holds humidity again – tears and gaps let moisture escape and make your humidifier work harder
- Thicker than the original – upgraded 10 mil clear material stands up to handling and zipping
- See every shelf – crystal-clear material lets light in and lets you check your grows without opening up
- Exact fit – made for the Ecosphere and Martha tent frames in 4-tier and 5-tier sizes
Which size do I need?
- 4-tier cover (RC1) — fits 4-tier Ecosphere, Foundation Edition and Martha tent frames, 63" tall
- 5-tier cover (RC2) — fits 5-tier Ecosphere, Foundation, Essentials, Monster Monsoon and Martha tent frames, 75" tall

How to swap it
- Empty the tent. Move your grows out and unplug any humidifier, lights or fans.
- Remove the old cover. Unzip it and lift it off the frame.
- Fit the new cover. Slide the new cover over the top of the frame and pull it down evenly on all sides.
- Re-fit your accessories. Re-apply filter disks and re-route hoses and cords, then zip it closed.
Cover only: this listing is the cover without the frame. For a complete tent, see the Martha tent.

Common questions

Yes. The Martha tent uses the same frame as the Ecosphere, so the matching 4-tier or 5-tier cover fits it.
Does it include the frame?
No. This is the replacement cover only. The frame, shelves and accessories are not included.
Which cover fits the Monster Monsoon?
The Monster Monsoon is a 5-tier system, so choose the 5-tier cover.
Is it thicker than the original cover?
Yes. It is an upgraded, thicker 10 mil clear cover designed to hold up better to regular use.
