Vitavia Neptune Greenhouse
The Vitavia Neptune is the unsung hero of the 8ft-wide category. By utilizing a single sliding door and standard eaves, Vitavia has created an 8ft-wide greenhouse that offers 30% more floor space than a standard 6ft model, without the premium price tag of the Jupiter range. It features comprehensive diagonal bracing in the roof and sides as standard, ensuring that this wider span remains rigid against UK winds.
🔧 Matt's Installation Tip: Structural Bracing
The Neptune spans a full 8ft width, which puts more load on the ridge than smaller models. Because of this, Vitavia includes roof and side diagonal bracing as standard features.
Crucial Step: Do not skip these braces during assembly. They are not optional extras; they are the "muscles" that lock the frame square and rigid against wind. Once these are bolted in tight, the frame becomes incredibly solid, but without them, the larger 8ft span would be vulnerable.
Why We Chose This Range
“We stock the Neptune for one main reason: it is the best value 8ft-wide greenhouse on the market. Most manufacturers force you to upgrade to expensive 'premium' ranges if you want an 8ft width. Vitavia built the Neptune to give you that massive internal growing space without the extra cost of double doors or fancy eaves. It is the perfect 'grower's greenhouse' where space matters more than luxury features.”
— Matt, Founder of Greenhouse StoresCommon Questions About the Vitavia Neptune
What is the difference between the Vitavia Neptune and the Jupiter?
Both are 8ft wide greenhouses. The Neptune is the "Entry Level" version featuring a single sliding door and standard bracing. The Jupiter (also known as Oregon) is the "Premium" version which adds double sliding doors, higher eaves, and enhanced integral base features.
Why does an 8ft greenhouse only have a single door?
The single door on the Neptune is a design choice to maximize internal wall space and keep costs down. By using a single door, you gain extra wall width at the front for staging or shelving, which some growers prefer over the wide access of double doors.
What sizes are available?
The Neptune is available in four lengths: 8x8, 8x10, 8x12, and 8x14. All models share the same 8ft width.
Is the frame strong enough for the 8ft width?
Yes. The Neptune includes extra roof and corner bracing specifically designed to support the wider 8ft span. It comes with a 12-Year Manufacturer Warranty for peace of mind.
