Louvre Vents & Automatic Roof Ventilation
The Rhino Premium greenhouses are fitted with as much roof ventilation as possible, using a combination of roof vents to make sure the maximum area is achieved. All the roof vents are controlled by solar-powered automatic vent openers.
Vents on the Rhino Premiums are also fitted with storm locks, allowing vents to be secured down. This is ideal when bad weather is expected, allowing the entire structure to be made airtight. *Note: it's important to disengage the vents before putting the storm locks into position, to avoid causing any damage to the openers.
The high quality Rhino five-blade louvre vents allow you to take complete control of your ventilation, allowing cool air to enter from the side, circulate up through the greenhouse forcing air to escape through the roof vents. Optimal circulation can only be achieved through a combination of roof vents and side louvres.
Adequate ventilation is absolutely crucial to successful growing under glass.
4mm Toughened Glass
Keep yourself and your family safe with Rhino's combination glazing system: Toughened Safety Glass and Rubber Glazing Beads. Perfect for exposed locations and families with young children and pets.
Rhino Tuff 4mm toughened safety glass is 33% thicker than most greenhouse glass and comes as standard with every Rhino greenhouse. The panes are designed with safety in mind, meaning breakages are less likely while ensuring that, if broken, the glass will shatter into lots of tiny pieces rather than big shards that are far more likely to cause injury. Even the edges of the glass are rounded so that you don't cut yourself during installation. And with Grade A glass, you can achieve ultimate clarity for maximum light.
The unique Rhino glazing system locks each pane of glass in place along its entire length, using long rubber beads. The glass cannot be blown or sucked out of the frame and pushing on the glass only locks the beads more tightly into the frame, making it ideally engineered for high winds and other extreme weather conditions. With Rhino's glazing method, each pane becomes integral to the strength of the whole frame. The Premium range also features box-section glazing bead for even greater stability, as a step up from the Classic range.
When compared with the glazing that comes as standard on most greenhouses, the Rhino ranges come up trumps every time. No dangerous horticultural glass or flimsy W-clips here; and with the smooth finish achieved by our glazing beads, there's no need for bar capping either.
Strong Frame
The Premium range builds on the already great strength of the Rhino Classic with box section glazing bars and 3mm thick 'T' section bracing throughout.
Each Rhino frame has around 60% more aluminum than similarly priced models. But it's not just the weight, it's the clever design of the Rhino that provides it's inherent strength.
The Rhino has been tested for snow loading capacity by placing a half ton of sand bags on the roof.
Rhinos currently inhabit much of the UK and have withstood winds of 137 mph according to customer testimonials.
Integral Base
Every Rhino greenhouse includes a strong aluminum base in the price, which not only provides an incredibly strong foundation but also allows the Rhino to be erected simply onto firm, level soil – so there's no need for an expensive concrete base. Once the Rhino is erected, strong stainless steel ground anchors are concreted into position.
The Rhino can also be erected on concrete or paving slabs, in which case the stainless steel anchors are fixed using the fixings provided.
All Rhino greenhouses include a low threshold door and ramp. There is plenty of width for a wheelchair or wheelbarrow to enter with ease.
Hanging Basket Rails
Every Rhino greenhouse comes with two hanging basket rails.
The roof is so strong that it can easily handle this extra load, and it's a really useful feature. Your hanging baskets will thrive and it will also free up lots of space on your staging.
Rainwater Collection
Every Rhino greenhouse also comes with large integral gutters as well as downpipes and bends so you can collect and use the natural rainwater that your plants love.
25 Year Manufacturer Guarantee
Nothing says more about the quality of a Rhino greenhouse than the 25 Year Manufacturer Guarantee.
A generation of gardeners can rest assured that the frame and even the powder coated color finish are covered, in the unlikely event that the greenhouse fails.
Learn more about the manufacturer of Rhino Greenhouses.
Foundation
Unlike most greenhouse brands, the Rhinos can be erected on soil. This is only due to the strength created by its sturdy base and framework. A soil base should be level and fully compacted, freshly dug soil will shift too much and isn't suitable for use as a stable foundation.
Alternatively, paving slabs, concrete bases and brick or block perimeter can all be used as long as they are smooth and level.

Made for aggressive chewers
Size: Small (Pack of 1)
My aggressive chewers are obsessed. This is one of the only chew toys that actually lasts for them. Always have to buy 2 so they each have their own

If you have a chewer - This is the bone for you!
I have purchased this bone three times and thought it was about time I wrote a review. My dog is a chewer - No matter how tough the toy claims to be, he rips it apart in minutes. And although he has a few hard bones, he prefers the toys he can damage. I received this bone as a gift and expected it to be another one that would fall into the pile of rarely touched bones. But this is the bone that he grabs almost every day. I honestly don't know what makes this bone different, but he loves it! It holds up to heavy duty chewing no matter how much he chews it. It holds its shape and (apparently) its flavor. Little bits do break off and it shows wear over time, but it is very long lasting. Added bonus - As a dog parent, I love that it has no smell and it never gets wet/sticky/gross.
