About Our 8x6 Greenhouses
An 8x6 is the step most growers take when a 6x4 starts to feel tight. The extra two feet of length is enough for a proper potting end as well as a growing run, which is why it has been the country's favourite size for years. We keep 65 models in stock across Vitavia, Elite, Palram Canopia and Swallow, priced from £464 to £5,534.
You are choosing on three things: frame material, glazing, and eave height. Aluminium is the low-upkeep default; Swallow timber holds more heat and looks the part but costs more. For glazing, polycarbonate keeps an 8x6 warmer and copes with wind, while glass gives clearer light. If you grow tall cordon tomatoes or want hanging baskets, look at a high-eave model. Bigger plot? Compare the larger greenhouses; tighter one, the 6x6 greenhouses.
Why We Chose This Range
"The 8x6 is the workhorse of our whole catalogue, so the range has to earn its place. The Vitavia Venus 5000 is my default recommendation: it has the headroom for tomatoes, the glazing bars are stiff enough that the doors stay aligned, and you can get any spare part for it years down the line. If you have the budget, the Swallow Eagle 8x6 in timber is the one people keep for twenty years. I tell everyone the same thing though, spend the difference on a better base before you spend it on a fancier frame."
— Matt, Founder of Greenhouse Stores💡 Tip: Run your staging along the north side of an 8x6 and keep the south side clear for tall crops. You get even light on the seedlings and full sun on the tomatoes.
🔧 Matt's Installation Tip: An 8x6 carries a lot of glass
A full set of 8x6 glass is heavy, and that weight all rests on the base being dead level. Check both diagonals are equal before you stand the frame up, and bolt the greenhouse down at every corner. Get the base square and the rest of the build falls into place.
Matt's Pick: Vitavia Venus 5000 8x6
Best For: The all-round family 8x6 that does everything well.
Why I Recommend It: Proper tomato headroom, a stiff frame that keeps its doors true, easy spares, and a choice of horticultural, toughened, or polycarbonate glazing.

Frequently Asked Questions
-
Is an 8x6 greenhouse big enough?
For most households, yes. An 8x6 takes a growing run and a potting area at once, so you can raise seedlings, grow tomatoes, and overwinter pots without running out of room. It is the size we recommend to anyone unsure between small and large.
-
What can I grow in an 8x6 greenhouse?
A full season's worth. Think a row of cordon tomatoes, cucumbers or peppers down the warm side, with staging opposite for seedlings, herbs and cuttings. There is room to keep tender plants going over winter too.
-
Do I need a base for an 8x6 greenhouse?
Yes, and it matters more at this size. An 8x6 holds a heavy load of glass, so it needs a firm, level, square base, usually a manufacturer base kit on slabs or concrete. Get this right before the frame goes up.
-
Should I get a high-eave 8x6 greenhouse?
Only if you grow tall. A high-eave model adds headroom for cordon tomatoes, climbing crops, or hanging baskets. For general growing a standard-height 8x6 is fine and costs less.
-
Is aluminium or wooden better for an 8x6?
Aluminium for low upkeep and price; timber for warmth and looks. Swallow wooden 8x6 models hold heat better and include free installation south of Glasgow, but cost more than the aluminium Vitavia or Elite equivalents.
