The best portable greenhouse for winter is the Ohuhu Portable Mini Greenhouse for Indoor Outdoor, because its 36 x 36 x 58.5 inch size fits tall plants and its tear-resistant PVC cover holds warmth. For a walk-in frame that shields a row of pots from frost, the Ohuhu Pop Up Greenhouse for Outdoors is the strongest frost-ready pick.
A portable greenhouse does not replace a heated glasshouse. It is a frost shield and a season extender.
The right cover traps daytime heat, blocks cold wind and keeps hardy plants alive through the coldest weeks.
This guide ranks eight winter-ready portables by how well their size, cover and frame handle cold weather. If you want the wider category first, our greenhouse for winter guide covers fixed and portable types side by side.

The best portable greenhouses for winter at a glance
The Ohuhu mini wins on size and cover quality, while the walk-in Ohuhu and the Yesker balcony kit cover the other main winter set-ups. Pick by where the greenhouse will stand and what you need to protect.
Ohuhu Portable Mini Greenhouse for Indoor Outdoor: Best for tall potted plants
- 36 x 36 x 58.5 in
- PVC cover
- removable waterproof PE mat
- zippered roll-up door
A tall mini greenhouse with a tear-resistant PVC cover and a removable waterproof mat. It works indoors or on a sheltered patio.
Pros
- Taller than most mini greenhouses
- Removable waterproof PE mat
- Roll-up zippered door
Cons
- Not a walk-in size
- Needs a sheltered spot outdoors
Ohuhu suits a gardener overwintering tall potted plants on a patio or in a sunroom. Its 36 x 36 x 58.5 inch size gives upright plants headroom that low mini greenhouses lack.
The cover combines a transparent PVC outer layer with a PE grid layer. Ohuhu says the PVC admits light well while the PE adds tear resistance and UV protection.
A metal frame with a rust-resistant electrophoretic coating keeps the structure steady through wet weather.
A removable waterproof PE mat sits under the plants to catch drips and spilled soil. Roll up the zippered door on mild days to water and vent, then close it at night to hold heat.
The whole unit weighs 3 kg, so you can shift it indoors when a cold snap hits. Ohuhu also notes the kit works with seedling accessories such as a heating mat, which matters if you start seeds in it.
The trade-off is that it is not a walk-in, so you reach in from the front. For a taller, wider structure, go with the walk-in Ohuhu below.
Ohuhu Pop Up Greenhouse for Outdoors: Best walk-in for frost protection
- 48 x 48 x 63.7 in
- 210D Oxford and double-layer PE mesh
- mesh side windows
- U-shaped ground stakes
A pop-up walk-in tent that folds flat for storage and stands up to cold, wind and birds. Two mesh windows help control winter humidity.
Pros
- Folds to 24 x 24 x 2.75 in
- Mesh windows for airflow
- Removable PE floor mat
Cons
- Fabric cover holds less heat than solid panels
- Needs staking in open spots
Ohuhu's walk-in pop-up is the best frost shield for a group of plants you want to step inside and tend. Its 48 x 48 x 63.7 inch frame opens to standing height and folds down to 24 x 24 x 2.75 inches when winter ends.
The cover is 210D Oxford fabric backed with double-layer PE mesh. That thick fabric traps warmth and blocks wind better than a thin plastic sheet.
Ohuhu adds fiberglass rods, U-shaped ground stakes and glow-in-the-dark wind ropes for stability.
Two mesh side windows and a roll-up zippered front door control humidity. In winter you close both at night and crack one window briefly on sunny afternoons to stop condensation building.
The arched roof also keeps rain and snow from pooling on top.
At 4.79 kg it is light enough for one person to move, and the removable PE mat doubles as an indoor floor protector. Its trade-off against solid-panel greenhouses is heat retention.
Fabric holds less warmth than polycarbonate, so plan on a small heater for tender plants. See our greenhouse in winter guide for the temperature limits of each cover type.
Yesker Mini Greenhouse 71"x36"x36" Portable Small Green: Best for balcony growing
- 71 x 36 x 36 in
- transparent PVC cover
- two top zippered doors
- powder-coated iron frame
A tall greenhouse that fits along a balcony rail. The clear PVC cover lets sunlight in while the twin top doors vent heat fast.
Pros
- Clear PVC lets in maximum light
- Twin top doors for quick venting
- No tools needed to assemble
Cons
- Taller frame needs more headroom
- Light weight needs anchoring
Yesker fits a balcony, porch or narrow patio where floor space is tight. The 71 x 36 x 36 inch footprint runs tall on a compact 36 x 36 base, so it stands upright against a rail or wall.
The transparent PVC cover lets in strong light, which helps plants keep growing on short winter days. Two semi-circular zippered doors sit on top, so you open them wide to water and vent without crouching.
Close both to trap warmth when the temperature falls.
A powder-coated iron frame resists rust. The extended cover skirt lets you add weights when wind picks up.
Yesker says you can assemble it without tools and move it indoors when the season turns.
The tall 71 inch frame gives upright plants room to grow. It works well for taller pots and shrubs that need light and headroom.
If you want a compact corner unit instead, the Ohuhu mini takes up less floor space with its 36 x 36 base.
Bamworld 3-Tier Wooden Mini Greenhouse: Best for seed starting indoors
- 54 in tall
- three shelves
- eucalyptus wood frame
- 75% clear PE cover
A wooden shelf unit with a zip cover that turns a sunroom corner into a seed-starting station. It warms soil and blocks light frost.
Pros
- Three shelves for trays and pots
- Wooden frame won't rust
- Rolls up for watering
Cons
- Not built for heavy rain or gusts
- Wood can swell in humidity
Bamworld's wooden shelf unit turns a sunroom corner into a seed-starting station. Its three shelves and 54 inch height hold trays, nursery pots and herbs at eye level.
The clear PE cover lets in 75% of sunlight while trapping heat and blocking light frost. Bamworld says the enclosed cover warms soil enough to start seeds 4 to 6 weeks early.
Roll up the zippered door to water and vent. Each shelf has 15.8 inches of clearance, so standard nursery pots and seed trays sit under the cover without bending the plants.
The eucalyptus wood frame weighs 8.5 lb and won't rust. Assembly takes about 15 minutes with push-fit connectors.
Adjustable shelf heights fit plants of different sizes.
Its trade-off is exposure. Bamworld says it suits sheltered spots, not heavy rain or sustained gusts, and wood can swell in humidity.
Treat it as an indoor or covered-patio unit rather than a frost shield for an open yard. The Ohuhu mini is the tougher outdoor alternative.
56x30 Portable Walk-In Greenhouse with Shelves: Best for shelving space
- 56 x 30 x 76 in
- four bearing shelves
- PE cover
- roll-up zipper door
A full-height walk-in with four load-bearing shelves and a 63 inch door. The PE cover resists cold and corrosion for several seasons.
Pros
- Shelves hold 50 lb each
- Adult-height door
- Ropes and anchors included
Cons
- Narrow footprint limits floor planting
- PE cover blocks some light
This walk-in suits a gardener who wants shelves to organize a winter crop. Its four bearing shelves hold 50 lb each, and the 63 inch door lets an adult step inside without stooping.
The overall size is 56 x 30 x 76 inches. Each shelf is 12 inches wide with 17 inches between tiers, so seed trays and medium pots fit.
The PE cover resists low temperatures and corrosion, and it won't scorch seedlings the way some clear PVC can. That makes it the safer cover for plants in full sun.
Ropes and anchors come in the box to tie the frame down when storms roll through. One person can assemble it without tools, and at 14 lb the whole frame is light enough to drag to a new spot.
The narrow 30 inch depth is the trade-off: you get shelves rather than floor planting space. It fits a side yard or patio edge but not a wide bed.
The trade against the Ohuhu walk-in is cover warmth: the green PE cover blocks wind better but transmits less light than clear PVC.
Crown Shades 12x8 Pop-Up Walk-In Greenhouse: Best for large patio set-ups
- 12 x 8 ft floor
- one-push CENTERLOK frame
- PE cover
- three height settings
A big pop-up greenhouse that opens in seconds and shelters a whole row of pots. Three height settings suit plants at different growth stages.
Pros
- Very large floor area
- Opens without tools
- Mesh windows for airflow
Cons
- Big footprint needs open space
- Lightweight for exposed sites
Crown Shades covers a large patio with its 12 x 8 ft walk-in floor. One push on the CENTERLOK hub opens the frame without tools, and an internal support pole stiffens it more than a standard pop-up.
The steel frame is rust-resistant. Crown Shades says the PE cover and frame are built for year-round use, with wind ropes and stakes included for stability.
Three height settings change the roof level as plants grow. The maker also lists a smoother zipper tested for up to 10,000 uses and an anti-aging PE cover with enhanced UV resistance.
A roll-up zippered door and mesh windows keep air moving, which helps on mild winter days when you need to dump humid air.
The big footprint is the trade-off. It needs open space and gets caught by wind, so pick a sheltered spot.
It also flexes more than a rigid kit in a hard blow. Still, the maker rates it for year-round use with the included wind ropes and stakes.
Sannwsg Walk in Greenhouses: Best for easy seasonal moving
- 57 x 29 x 76 in
- galvanized steel frame
- PE cover
- detachable parts
A walk-in frame that comes apart without tools so you can move it with the seasons. A free indoor thermometer is included.
Pros
- Detachable frame for storage
- Galvanized steel resists rust
- Thermometer included
Cons
- Cover should come off in extreme weather
- Narrow walk-in width
Sannwsg is the easiest pick to move when the seasons change. Its 57 x 29 x 76 inch frame comes fully apart without tools, so you can store it flat in summer and rebuild it on a sheltered patio in fall.
The galvanized steel frame resists rust and fading. The PE cover holds heat and moisture for winter protection and seedling propagation.
Sannwsg includes a small indoor thermometer so you can track the temperature inside. The walk-in layout gives 17.5 inches between tiers for vegetables, fruits and flowers.
Shelving and a walk-in door let you organize plants and reach them easily. The maker advises removing the cover during extreme weather, so watch forecasts and take it off before a hard storm.
The narrow width is the trade-off: it walks in single file and holds fewer wide pots than the Crown Shades. It suits a compact yard that needs one reliable frost shield.
For an open site with room to spread out, the Ohuhu walk-in is the better fit.
Porayhut Pop-Up Greenhouse Tent: Best budget cold-weather tent
- 48 x 48 x 63.7 in
- 600D Oxford and double-layer PE mesh
- arched roof
- 12 ground stakes
A pop-up tent with an arched roof that sheds rain and snow. Thick Oxford fabric and 12 stakes give it winter staying power.
Pros
- Thick 600D Oxford fabric
- Arch roof prevents snow build-up
- Folds to 24 x 24 x 2.75 in
Cons
- Pop-up frame flexes in strong wind
- Mesh fabric cools faster than solid covers
Porayhut is the budget tent for a first winter. Its 48 x 48 x 63.7 inch pop-up opens without assembly and folds to 24 x 24 x 2.75 inches for storage.
At about 4 kg it is light enough to carry through a doorway.
The cover is thick 600D Oxford with double-layer PE mesh. Porayhut says the fabric gives good thermal insulation and the arched roof sheds rain and snow so it doesn't collect.
Twelve 15 cm ground stakes add wind resistance.
A zippered front door rolls up for access. Mesh windows on both sides vent humid air when you open the outer PE curtain.
Steel wire poles in the frame support the arched roof, and a carry bag is included.
The trade-off is the pop-up frame. It flexes in strong wind and its mesh fabric cools faster than solid covers.
It works for hardy plants and light frost but needs a heater for tender ones. Read our pop up greenhouse for winter notes before you rely on one.
How these portable greenhouses compare for winter
The table below lines up size, cover type and frame so you can match a greenhouse to your space and your plants. Heat retention follows cover type most closely: solid PVC and thick fabric hold warmth better than mesh-backed tent cloth.

How we compared these winter portable greenhouses
We ranked these eight by four winter-focused checks: how much heat the cover holds, how much light it lets in, how stable the frame is in wind and how much headroom or shelf space you get. A greenhouse that traps warmth but blocks light leaves plants weak by spring.
A clear cover on a light frame blows over in the first storm. The highest scores went to models that balance the two.
We also weighed size against the job each one does. A mini unit that fits a balcony earns points for fit even though it can't shelter a row of shrubs.
A large walk-in loses points when it needs open space most yards don't have. Anchoring hardware counted in the ranking too, since stakes and wind ropes are the difference between a shelter that stays put and one that ends up against a fence.
Our score weighs specs, features and buyer feedback against what you're shopping for. We did not test these units in a garden.
Every claim here comes from the brands' published specs and the features each model lists.
What cover material keeps a portable greenhouse warmest in winter?
A solid PVC or thick fabric cover holds heat best, while mesh-backed tent cloth cools faster and needs a heater. Cover type matters more than frame style once the sun goes down.
PVC is clear, so it lets in more light and holds warmth in a sealed space. The Ohuhu mini and the Yesker both use PVC covers.
Thick fabric like the Ohuhu walk-in's 210D Oxford or the Porayhut's 600D Oxford blocks wind and insulates well, but it lets in less light than clear plastic.
PVC covers
A PVC cover gives the best light-to-warmth trade-off for winter. It admits strong sunlight so plants keep growing, and it seals in heat when the door is closed.
The catch is that clear PVC can scorch tender seedlings on a bright day, so vent it.
PE and Oxford fabric covers
PE and Oxford covers block more wind and insulate better than thin film. They cut light, so plants grow slower but suffer less scorch.
The Ohuhu walk-in and the Crown Shades both use PE covers. The Porayhut uses Oxford fabric with a PE mesh layer.
The shelved walk-in's PE cover is also the gentler option for seedlings that burn easily under clear plastic.
Rigid panels versus portable covers
Rigid polycarbonate panels hold the most heat and last the longest. Portable covers win on price, weight and storage.
If you want panel-level warmth, our greenhouse for winter comparison covers kit options.
Do you need to heat a portable greenhouse in winter?
Only if you grow tender plants or face hard freezes. A portable greenhouse holds a few degrees above outside air on its own, which protects hardy plants from light frost.
Tender tropicals need extra heat.
The gap between inside and outside depends on cover thickness and how tightly you seal the frame. A fabric pop-up holds less warmth than a solid PVC cover.
A small heater, a heat mat under seedlings or a few jugs of water as thermal mass all extend the gap. The Ohuhu mini even works with a heating mat for germination, and the Sannwsg kit ships with a thermometer so you can see what your set-up actually holds.
Read our how to heat a greenhouse guide for the safe options. Run any heater on a thermostat and keep cords and fuel away from the cover.
Which size portable greenhouse fits a balcony or small patio?
A mini or low unit fits a balcony best, while a walk-in needs a side yard or patio edge. Measure your floor space and doorway before you order, since even a pop-up needs room to open.
The Yesker at 71 x 36 inches runs tall on a compact base. The Ohuhu mini at 36 x 36 inches fits a corner and still gives tall plants headroom.
The Bamworld shelf unit at 23 x 17 inches takes up less than a doormat.
Mini and shelf units
Mini and shelf units suit one or two plants or a seed-starting tray. They warm fast and are easy to move indoors.
The trade-off is limited headroom and less air volume, so they swing in temperature faster. A shelf unit like the Bamworld adds tiers for trays without adding floor space.
Walk-in frames
Walk-in frames shelter a group of plants and let you work inside. They need more space and more anchoring.
The Ohuhu walk-in at 48 x 48 inches is the smallest walk-in here, while the Crown Shades at 12 x 8 ft needs a real patio. Between the two, the shelved walk-in fits a side yard and the Sannwsg suits a narrow strip along a fence.
How do you keep a portable greenhouse stable in winter wind?
Stake every corner and use the wind ropes, then site the greenhouse out of the prevailing wind. Winter storms hit a light pop-up frame hardest, so the base and the anchor points do the most work.
The Ohuhu walk-in ships with U-shaped ground stakes and glow-in-the-dark wind ropes. The Crown Shades includes ropes and stakes.
The Yesker and Porayhut both extend the cover skirt so you can weigh it down. The shelved walk-in adds ropes and anchors in the box as well.
Clear snow off the roof after each storm. The Porayhut's arched roof sheds snow, while flat or peaked covers can sag under the weight.
On any pop-up frame, take the cover off before a hard blow rather than testing the stakes.
Can you leave a portable greenhouse up all winter?
Yes, if it's staked and the cover is rated for cold. Leave a sturdy walk-in up through the season and remove the cover only before extreme storms.
A light pop-up with thin fabric may not last through heavy snow.
Check the frame after each storm and tighten the ropes. Remove the cover if the maker advises it during extreme weather, as Sannwsg does.
Store the greenhouse flat in summer to extend its life. Frames with rust-resistant coatings, like the Ohuhu mini's metal poles and the shelved walk-in's steel pipes, handle a wet season better than bare metal.
Verdict: which portable greenhouse should you buy for winter?
For most gardeners, the Ohuhu Portable Mini Greenhouse for Indoor Outdoor is the best portable greenhouse for winter, because its tall PVC cover protects upright potted plants without taking much floor space. Step up to the Ohuhu Pop Up Greenhouse for Outdoors if you want to walk in and shield a group of pots from frost.
The other picks fit narrower jobs. The Yesker is best for a tall balcony set-up.
The Bamworld suits a sunroom seed station. The shelved walk-in fits a side yard.
The Crown Shades covers a big patio. Sannwsg moves with the seasons.
The Porayhut is the budget first tent.
Pick by your space and your plants first, then add heat only if you grow tender varieties. Our greenhouse in winter guide explains what each cover type can and can't do once the temperature drops.

Frequently asked questions
Can a portable greenhouse keep plants alive in winter?
Yes, a portable greenhouse can keep hardy plants alive in winter by trapping daytime heat and blocking frost. It works best as a frost shield and season extender, not as a heated grow room.
Tender tropical plants still need a heat source or to come indoors.
What temperature does a portable greenhouse hold overnight in winter?
An unheated portable greenhouse typically stays a few degrees warmer than outside air overnight, depending on cover thickness and how well it is sealed. That small gap protects hardy plants from light frost but not from hard freezes.
Add a heater or thermal mass when nights drop far below freezing.
Is a pop-up greenhouse warm enough for winter?
A pop-up greenhouse is warm enough for winter when you pick a fabric or PVC cover and close it tight at night. Its tent-style cover holds less heat than rigid panels, so it suits hardy plants and frost protection.
For tender plants, pair it with a small heater.
How do you stop a portable greenhouse blowing over in winter storms?
Stake every corner and use the wind ropes that come with the frame. Put the greenhouse in a spot sheltered from the prevailing wind and add weight to the base or cover skirt.
Clear snow off the roof before it piles up.
Should you vent a portable greenhouse in winter?
Yes, open a door or window briefly on sunny winter days to let humid air out. Trapped moisture encourages mold and rot on leaves.
Close it again well before late afternoon so you keep the stored heat overnight.
