Tomato greenhouse buying guide

Updated: October 2026

You are choosing a cover for cordon tomatoes on a patio or an allotment, and the stars are easier to read than the measurements. A tomato greenhouse buying guide should settle the footprint first. On amazon.co.uk these are portable polyethylene covers on a push-fit frame, about 100 cm long for one grow bag or about 2 m long when several pots share a roof. The [tomato greenhouse comparison](/hub/raised-beds-greenhouses-and-compost/tomato-greenhouse) is the eight-row table in GBP. This page is the order of those decisions, and it does not name a winner. The Products Compared editorial team used the listings, plus notes from the Royal Horticultural Society and the Planning Portal, and checked the type on 16 October 2026. A qualifying purchase can earn us a commission at no extra cost to you.

One bag or a 2 m cover

One standard growing bag points to the houses about 100 cm long. The Royal Horticultural Society plants two tomatoes in a standard bag and one in a 30–45 cm pot. DIVCHI at £15.47 and Bergmis at £14.99 are that footprint, and the white and green VOUNOT houses are 100 × 50 × 150 cm at £23.49 and £24.99. Several pots point to the covers about 2 m long. Outsunny is 200 × 76 × 168 cm at £27.99, and Ohuhu white or green is £49.99. Keep one bag on the tomato greenhouse for a grow bag page.

Pegs, ropes, or weights

Soil can take pegs, and paving cannot. Bergmis states eight 18.5 cm J-hook pegs, four guy lines, and inner straps. Outsunny states four guy ropes and four pegs, and the listing says not to leave the house up in high winds. On slabs you weight the skirt and tie the ropes to a fence or a wall. Tension and base weights are on the how to put up a tomato greenhouse page.

Cloth and a roof that stays taut

Bergmis and Ohuhu state 130 g/m² polyethylene, and VOUNOT states 135 g/m². That is a stated weight, not a measured life in seasons. DIVCHI’s technical line says PVC and polycarbonate and gives no grams per square metre, so the weight is n/a, and Outsunny’s captured bullets omit it too. A slope sheds rain only while the cover is taut. Bergmis describes tension cords and a centre pole, while DIVCHI reviewers report pooling and sagging that loads the zip.

Stars you must not add twice

Ohuhu white and green share one 4.3 from 814 pool, so the colour is not a second sample of buyers. The three VOUNOT raw files share the same review texts, so 4.4 from about 145 is one sample, and the stories match the small house more than the 200 cm size. Bergmis is 5.0 from one review written before a season of use.

Common questions

Do I need the 100 cm house or the 200 cm cover?
Use about 100 cm for one standard growing bag. The Royal Horticultural Society plants two tomatoes in that bag, and DIVCHI, Bergmis, and the VOUNOT 100 × 50 × 150 cm houses are those rows, from £14.99 to £24.99. Use about 2 m when several pots share one roof. Outsunny, the VOUNOT 200 cm house, and Ohuhu run from £27.99 to £49.99. Check a walk-in title against about 168–170 cm of headroom.
What holds it on soil, and what holds it on paving?
Soil can take the pegs in the box. Bergmis states eight 18.5 cm J-hook pegs and four guy lines. Outsunny states four pegs and four guy ropes, and it says not to leave the house up in high winds. Paving will not hold those pegs, so weight the skirt and tie the ropes to a fence or a wall. If peg length is never stated, you add that hold-down yourself.
Which listings state grams per square metre?
Bergmis and Ohuhu state 130 g/m² polyethylene. VOUNOT states 135 g/m². DIVCHI’s line says PVC and polycarbonate and gives no cloth weight, so that figure is n/a. Outsunny does not state grams per square metre in the captured bullets, so that figure is n/a too. A stated weight is not a life in seasons, and 150 g/m² from another shop does not fill a blank row.
Does a sloped roof actually shed rain?
A slope sheds rain only while the cover stays taut. Bergmis describes tension cords and a centre pole. If the cloth sags, water pools, which DIVCHI reviewers report, and the load sits on the frame and the zip. Ropes, pegs, or patio weights keep the pitch after a wet week. A photograph of a pitched cover is not that cover a week later.
Are the three VOUNOT ratings three samples?
No. The three VOUNOT files share the same review texts, so 4.4 from about 145 is one sample. The stories fit the small house better than the 200 × 77 × 170 cm size. The listings remain separate products at £23.49, £24.99, and £36.99. Counting the stars three times would invent two extra samples.
Do I need planning permission for a house under 1.7 m in England?
These covers are under 1.7 m, so the 2.5 m boundary-height cap rarely stops a house in England. Class E, as the Planning Portal summarises the 2015 order, still keeps an outbuilding behind the principal elevation and under half the curtilage. Flats, listed curtilage, and land in front of the house are different, and Scotland, Wales, and Northern Ireland are not that order. An allotment can ban thin polythene, so ask the association before you buy for a plot.
