Buying a Greenhouse (5)

Do you need planning permission for an orangery?

When building an orangery, you are usually not required to seek planning permission. It is classed as a permitted development, similar to a conservatory, and is subject to the same building regulations and guidelines. As long as you build within these rights, planning permission for an orangery is not necessary.


An orangery is a more affordable option compared to an extension, mostly due to the materials used. The overall cost per square metre of an orangery is generally cheaper than a single-story extension, depending on which style and design features you opt for.

Are there different sizes of Victorian greenhouses?

There are different sizes of Victorian greenhouses available. Often, Victorian style greenhouses are quite large due to their impressive features.


However, you can get small Victorian greenhouses or a Victorian mini greenhouse. Size and construction materials can vary, and it is all dependent on the individual’s garden tastes.


Here at Hartley Botanic, our traditional greenhouse style can be adapted and customised to meet any personal requirements you may have.  We have a huge variety of Victorian greenhouse sizes available for you to choose from.


Here are some of the styles and sizes we have to offer:

What is the best floor for a greenhouse?

The best floor for a greenhouse is flooring explicitly designed for your needs and your greenhouse growing intentions.

If you intend to grow directly from the ground or if you would like a decorative flooring, there are solutions for all needs.

What type of glass is used for a greenhouse?

Greenhouses should ideally have a toughened safety glass to protect from potential damage rather than the standard 3mm horticultural glass which is more prone to breakage.

At Hartley Botanic, we use 4mm toughened safety glass, which is strong and does not splinter if broken.

What colour should a greenhouse be?

The colour of the outside of a greenhouse is up to personal preference. When choosing the greenhouse colour picture, the greenhouse within your garden, next to your house, and with the potential background.

Hartley Botanic has a large choice of colours to choose from. The greenhouse colour cannot be changed, as our greenhouses are powder coated to provide a long-lasting finish.

Greenhouse Maintenance (5)

When should you remove bubble wrap from a greenhouse?

The decision to remove the bubble wrap from your greenhouse is a personal one that is influenced by the weather, the temperature inside, and the condition of the plants.


Bubble wrap acts as insulation and is therefore ideal for keeping heat in the greenhouse during the colder seasons to grow winter vegetables. During the warmer months, however, the insulation may cause an imbalance in the humidity inside your greenhouse, causing plants to rot or wilt.


Another reason to remove bubble wrap from your greenhouse is when you need to clean it. By removing the wrap, you will be able to thoroughly clean all of the corners as well as any shelves or staging you may have.

How do you build a greenhouse misting system?

Greenhouse misting systems are a perfect way to care for your plants. Although they can be bought, you always have the option to build one yourself.


While you don’t need many materials to create a misting system, you do need to ensure you have a plan before going into the building stages.


Here are some top tips on building a greenhouse misting system for a small greenhouse.

  • Make sure all your parts fit together and check the measurements. You don’t want to reach the installation stage to find out your parts don’t fit.
  • Focus on your water source. Check that a tube adaptor will fit, that the pressure control is appropriate and how far you’ll place the tap from your greenhouse.
  • Create the misting system based on what plants you are growing and the climate.
  • Having a misting system is not a substitute for having good ventilation. Before you create a misting system, ensure you have strong ventilation.


To build a small greenhouse misting system, you first need to place a filter (ideally mesh) onto the tap. Once you’ve screwed the adapter onto the tap, push the “barbed” end into the tube and make sure it fits properly.


Then, you need to run tubing from the tap along your greenhouse or shelving. It is best to attach a few zip ties on the way to keep everything in place. When this is done, add your end cap to the end of your water supply tubing.


Wherever you’re hoping to insert a nozzle, cut the tubing, insert the compression fittings you have chosen and press in a nozzle at the bottom of each compression fitting.


Finally, you’re ready to turn on the water. You must turn the water on slowly to ensure you have the correct water pressure for the nozzles.

How do you maintain a small greenhouse?

A small greenhouse is an exciting addition to any garden, but maintenance should be done regularly to create the perfect environment for whatever you choose to grow.


By cleaning, disinfecting and sweeping your greenhouse, you are sure to keep pests away and have a controlled area. It is also important to deal with any weeds and remove any plants that develop diseases, as they can be transferred around your greenhouse very easily.


One of the best ways to maintain your small greenhouse is by undertaking daily observations. This way, you can be on the lookout for any pests or see any areas that need an urgent clean.

How much ventilation does a small greenhouse need?

Ventilation is crucial to controlling the temperature and managing humidity levels inside your small greenhouse. By having a good amount of greenhouse ventilation, you provide your plants with the nourishment they require to survive.


The easiest way to ventilate a greenhouse is by having roof or side vents that provide regular cooling air changes throughout. The standard rule is, for every 50 sq ft of floor area, you should aim to have ten sq ft of ventilation.

How much does it cost to maintain a greenhouse?

Multiple variables impact the cost of greenhouse maintenance, such as water, heating, and lights.

The costs to maintain a greenhouse will vary depending on the climate where your greenhouse is located, the size of it, and the materials, for example, aluminium will only require cleaning.

Heating a Greenhouse (5)

Do mini Greenhouses protect from frost?

Mini-Greenhouses are great protectors against frost during winter. Many growers use Greenhouses to protect their plants from the elements over the colder months, including frost and other harsh conditions.


Temperatures are typically around five degrees higher inside a mini-Greenhouse, keeping your plants from freezing.


You may want to consider further artificial ways of heating your mini-Greenhouse, particularly during an extreme winter or if you have plants that prefer a warmer climate.

Mark as helpful

Why should you put bubble wrap in a greenhouse?

Gardeners add bubble wrap to their greenhouses primarily to add another layer of insulation. Bubble wrap retains any valuable heat from the day, which can be used to protect against frost at night.


It is important to remember, however, that bubble wrap retains heat. So, during the warmer months, it is critical to monitor the conditions inside your greenhouse to avoid any plants wilting.

How do you heat a small greenhouse?

There are a few methods you can use when it comes to heating a small greenhouse.


For example, having a controlled electric heater is a good option. However, you would need to ensure your greenhouse has mains electricity to power it.


As well as electric options, there are more cost-efficient methods such as heat sinks and having proper insulation. By effectively insulating your greenhouse, you can reduce the loss of any heat and improve the general structure.

How do you cool a greenhouse?

The best way to cool a greenhouse is by making sure the greenhouse has good airflow and ventilation.

In order to improve greenhouse ventilation, and cool it down, make sure to keep vents open, have plenty of opening windows and install blinds. To cool a greenhouse quicker, leave the door open or use a fan to circulate the air quicker where possible.

Mark as helpful

When should you insulate a greenhouse?

A greenhouse should be insulated when the night-time temperatures are expected to drop below 5 degrees Celsius.

As the temperature differs from one area to another, keep an eye on the daily weather forecasts.

Preparing the Site (5)

What is the best position for a glasshouse, what do I need to consider?

The best position for a greenhouse is in as much sunlight as possible during all seasons of the year. One of our most important greenhouse position tips is to avoid locating your greenhouse in the shadow of tall trees, boundary fences or walls as these will obstruct light.


For lean-to greenhouses placed against a wall, a south-facing position is ideal. For stand-alone structures, the ridge along the top of the greenhouse should ideally run from East to West, this will allow the sun to run along its longest side during the day. Other elemental considerations include a location to avoid prevailing winds to reduce unnecessary cooling and choosing a site which is not shaded, but equally not too exposed to the cold. If possible, choose an area which is easily accessible from the property allowing you to ‘pop-in’ to the greenhouse regularly.

How do I decide where to site my new greenhouse?

When deciding where to place a greenhouse, basic considerations are good light and shelter from strong winds. Ensure the ground drains easily and is level. If water and power services will be required, make sure these are laid on prior to the arrival of the greenhouse, or make schedule to lay them on at a later date.


All too often greenhouses are relegated to neglected corners of the garden, whereas to be used effectively, the distance from the property should be minimised, so you can simply “pop into the greenhouse” easily. Make sure to have the door closest to the house if possible. Running the ridge “east to west” is recommended to allow maximum light into the greenhouse

Do you measure and install the greenhouse on two levels?

Yes we would visit site, measure and prepare a quotation for you. If you then placed an order our technical office would visit to take accurate measurements to enable us  to prepare detailed drawings for the base to be built. We would then install the greenhouse onto your pre-prepared foundations.

Erecting a Greenhouse (5)

Can I build my greenhouse myself?

Some of our smaller greenhouses can be assembled by the customer, however, some Victorian glasshouses are more complex. 

If you are looking for advice on how to build a Victorian style greenhouse, the Hartley Botanic team will assemble it to a high standard, and the cost of this is included in the greenhouse pride.

When is the best time of year to build a greenhouse?

The optimum time to build a new greenhouse would be either at the beginning or end of the growing season. Orders placed late in the year or early in the year between November and March will enable you to get your new greenhouse up and running for the start of the growing season. However there is really no reason why you shouldn’t put a new greenhouse in at any time which suits you and your circumstances.”

Existing Hartleys (5)

How can I maximise space in a small greenhouse?

If you’ve opted for a small greenhouse, there are plenty of ways you can maximise your space to have the best growing experience possible.


To begin with, every bit of space counts, so make sure you’re aware of how much area you have available for you to use.


If you’re looking to optimise your space, consider adding greenhouse accessories. Whether it be high level shelving or aluminium staging and shelving, you immediately gain space to pot your favourite plants.


Another main way to maximise your space in small greenhouses is to create a schedule and plan ahead. If it’s possible, focus on having your greenhouse at full capacity as often as you can. By doing this, you know when things will be fully grown and when you can add more plants.

How can I open a stuck greenhouse lock?

If the lock was last used some time ago the bolt may have become stuck due to moisture , debris, corrosion etc. We would suggest a penetrating / water dis-placing oil (WD40 or similar) applied liberally into the lock mechanism. This should release the lock.

Hi we have just moved into our house and it has an 8' wisley greenhouse with an inward opening door, is it possible to change this to one that either opens outwards or slides as it takes over a lot of the internal space?

It would be helpful to know the age of the greenhouse before we could give an answer to this question In the first instance we would need to talk with you and possibily request a photograph of the greenhouse to see if we could assist.

Moving a Hartley (2)

I have two questions, firstly I am moving to Scotland in the future and there is a hartley greenhouse that needs to be resited and the seals have shrunk and would need replacing .The glasshouse is approx. 15/8ft. and has a brick base.Would you know which model from this brief description? It is quite old, but in reasonable order and seems to be the style favoured in this area. The second query is related to me getting a quote from an aluminium conservatory company for a conservatory approx. 5mtrx3mtr, but the quote was well out of my budget and I wondered if another option would be a lean to glasshouse but there are no prices shown and I need to have some idea in order to know if this is an option.

We wouldn’t unfortunately know the model from the brief description, however if you could provide photographs this would help?

Second query answer – If you could give us an idea of size required for the lean to greenhouse, we would be more than happy to provide an estimated cost for you. Please contact us for more information.
