Welcome to our greenhouse planning guide.

Here you will find the best tips and ideas for planning your first successful greenhouse.

Planning a greenhouse  in advance is an important strategy for your greenhouse growing success.

Greenhouse gardening just like any other type of gardening  style have some basic guidelines you should know up front.

Follow them to avoid common greenhouse issues in the future.

Listed below you will find reasons why we will need a future greenhouse formed from the research I have completed on this subject.

Learn why  greenhouses may play a critical role in our future food growing efforts.

Greenhouse gardening may  become necessary in the near future to insure a stable healthy food supply for our families.

Whether you are planning to grow your own food or plants for resell to others this information will be worth reading.

Growing vegetables, herbs, tropical plants,fruit trees or even medicinal herbs for healing this guide will help in the decision making process.


What Is The Purpose For Having A Greenhouse?

Having a greenhouse will shield plants from excessive temperatures.

Greenhouses provide fruiting plants with a stable growing environment to increase yields.

This environment is required for proper seed germination and optimal plant growth year round.

Farmers interest in greenhouse growing is on the rise these days due to what I believe to be the issues of  failing crops throughout  the U.S..

Crop failures have been taking place throughout the world due to extreme storms and unstable weather conditions.

These issues have led to weather uncertainty that has been haunting our country for the past few years.

It seems to be on the horizon for some time to come in our near future.

Granted, I know not all of the farmers can just go out and convert their acreage into greenhouses.

Farmers could consider this greenhouse growing idea in addition to their other growing methods.

At the least they can sustain their own food supply and possible supply their local communities.

Greenhouses could raise some food stock for some  small animals like for instance rabbits, chickens and other livestock.

The possibilities of growing in greenhouses are endless when you use your imagination.

You are able to grow food year around in a safe controlled environment.

In the near future if things don’t change, some of us will have to resort to gardening under shelter in greenhouses.


Concerning Future Extreme Weather Issues

Growing indoors may become  necessary to keep an affordable supply of healthy food on our tables.

This is due to the world experiencing a grand solar minimum causing these extreme weather issues that could last for years to come.

Recent reports have predicted that we will be experiencing longer and colder winters with more severe storms throughout the year.

These reports compare to times like during the Dalton minimum Of the 1930’s.

Issues in this era caused a huge migration of people  to shift to other regions of the country to avoid starvation.

This was due to the fact that they could no longer sustain a healthy lifestyle by growing their own food in certain areas of our country.


Rising Food Prices Due To Future Shortages

We are already starting to see the cost of food items on our grocery store shelves increasing on a regular bases.

Price hikes are due to our recent extreme weather events that hit our mid west and many other food producing states,

these storms caused about 19 million acres to not be planted  just this last year according to recent reports.

Taking all this information into consideration led me to writing this article about the need of greenhouses in our near future.

This is climate change in action is a real and serious issue.

It has very little to do with what we do in our daily lives.

The storms have everything to do with what our sun is doing and how the earth is reacting to it.

Don’t believe the myths created by some politicians designed to generate huge amounts of cash to stuff in their pockets.

The science and the proof is all around you.

Records show this has happened before several times in our past.

We need to learn alternative methods to grow food to get through it a without moving to a different regions of the country like those in the past.

This is a serious issue on our horizon as predicted by the people who study the weather  and solar cycles.

There is always a chance this won’t come to pass as they predict but it is always better to be safe than sorry.

When you have a greenhouse you will always be able to grow a  garden.

Grow your own food any time of year no matter what the weather is doing outside.


Can You Use A Greenhouse In The Winter?

Yes, this the time of year a greenhouse operates its best.

You can start seeds for your favorite plants and grow them all year long.

Their main benefit is to allow growers to produce food crops anytime of the year including winter.

Greenhouse designs  are made up of mainly glass or plastic that is great for collecting  solar energy from the sun..

The design gives the greenhouse the ability to collect the heat from the sunlight and trap it inside of the structure.

  Greenhouses convert the electromagnetic energy from sun into heat warming everything inside the structure.

 This allows plants inside to grow even when the temperatures below freezing outside during the winter months.


What To Grow In The Winter

Some of the best cool weather vegetable  plants which can be grown in the winter are

  • Cabbage
  • Broccoli
  • Lettuce
  •  Kale
  • Spinach
  • Carrots
  • Collards
  • Brussel Sprouts
  • Garlic

Along wit any other cool weather crop you wish to grow including most herbs.

Many people even grow exotic tropical fruits in these greenhouse structures year around when set up properly.

Most plants grow well in the greenhouse with the proper amount of light and warmth .

When it comes to supplemental heat there are some using compost piles inside the structures.

The compost piles supply a continuous heat source while breaking down during the cold months for extra warmth.

Heaters can also be used to heat during times when there is no sunlight present for days and extreme cold is present.

Heating units can run on electricity or solar powered battery banks with converters you can buy or make for yourself.

Glass Or Plastic… What Greenhouse Design Is Best For You?

There are many types of greenhouses for sale that you can purchase in greenhouse  kits  or you can build one from scratch.

The type of greenhouse you choose all depends on which best suits your purpose.

Hoop style greenhouses have always been very popular in the past.

It is most likely because they are  economical to build up front.

With the intensity of the sun rays and extreme storms we have these days you could bet the plastic covering will have to be changed more frequently.

Frequent  replacement will be due to the extreme weather elements breaking down quickly.

PVC greenhouses are definitely the ticket when it comes to how to build a greenhouse cheap.

This type of greenhouse may not be economical in the long run and could have huge maintenance costs.

They tends to receive more due to frequent damage when living in climate with rough weather.

Some well known growers have reported in the past that these lightweight hoop houses had taken flight during freak storms producing high winds.

This issue had been blamed on not being anchored properly as a result causing property damage and even being completely destroyed.

If you choose this type of greenhouse make sure the anchors are in place properly.

This type of strong winds can come with any storm from this day forward because of our unstable climate.


Framed Greenhouses

For a stable permanent greenhouse solution, building a framed type permanent structure using glass would be best.

Windowed greenhouses may cost more in thee beginning but maintenance and energy costs should be much lower over time.

This type are also very durable and can last for many years.

Years ago I had read were many years ago they used these wooden type greenhouse structures with the glass.

These greenhouses  were able to grow anything they needed in extremely cold weather.

The book did mention they did have some issues when the weather was warmer  due to the poor ventilation at the time.

Today we have solid electrical systems and good economical fans to supply proper ventilation.

This would solve most of the issues they had in the early years.

These things will be important to do some in depth research while greenhouse planning.

Research to figure out what design suits you best and which type would be the most affordable over time.

Find a type to suit your plans before jumping into the game.

I would bet that a few good people with good quality shed building plans, a batch of used glass and some pressure treated lumber could have a free standing gable roof  garden  greenhouse built in a weekend.

Building a greenhouse of this type would last for years.

Besides building the main greenhouse structure  you  will need some office space and storage buildings to keep your stock in.

These building plans would a good investment to serve many purposes for your greenhouse planning  project.

Where Should You Position A Greenhouse?

The greenhouse should be positioned toward the southwestern part of your property away from trees and other buildings.

These may block sunlight in a way that the walls most used for growing get the most direct sunlight.

In other words track your sunlight, It moves basically east  to west.

You want the widest side of your greenhouse structure as close to parallel as possible with the movement or direction of the sun.

This provides the most sunlight to as many plants as possible .

Your greenhouse end walls not used for much growing with the entry ways and  ventilation fans and other utilities should be facing east and west.

The positioning will be completely relevant to the size of the structure you will be able to build to fit the size of your property.

Wider properties east to west  may be better for larger structures while properties running north to south will need multiple smaller structures.

During your greenhouse planning keep this in mind

Many land plots are very unique and the shape and layout of your  existing property may directly affect your productivity.

Good greenhouse planning is important because the structures  layout has to be right.

Property shape and size plays a huge role in making this plan work out.

 10 Important Ideas To Consider Before Construction Of Your Greenhouse Project!


Space Requirements 

The area required depends on your business plan whether you will be following a retail or wholesale model.

The minimum space should be at least a minimum of at least a couple of acres to make room for office space, separate parking spaces for employees and customers, driveway access for deliveries, warehouse buildings for storage and room for future expansion if needed.

 A wholesale venture like a plant nursery generally will require more space because the greenhouses will need to be much larger.


Zoning For Your Greenhouse Location 

These are local or state regulations that control land use within the jurisdiction of incorporated cities and towns to encourage safety.

Health codes are established for the  well being of the community. Greenhouse operations are only permitted to operate in designated zones within the corporate limits. 

Road frontage use regarding signs, driveways, parking spaces office space and restrooms should be planned according to their rules. 

If you are within the city limits you should consult with your city zoning officials and ask what is required regarding building codes so you will know what permits will be needed in advance.

When  planning operations outside city limits, the county and state regulations may apply. Contact your county officials for advice.


Highway Access To Your Greenhouse Business 

Site location with regards to highways should be taken into consideration for long term business goals.

If you are planning for a retail business you will want the walk in traffic that would come natural with the visibility of a  high traffic location.


Retail Business Location For Your Greenhouse

 Location with frontage along side a high traffic road or beside a considerable residential site can greatly increase business.

Wholesale business needs access to some major highway to deal with pick up and deliveries by truck and road traffic.



Select a location that is away from heavy industrial pollution.

Somewhere right outside the city limits is usually better for agriculture type businesses, the air is cleaner, taxes lower and less restrictions in general. Be aware your state may require licensing for commercial food growers and have strict guidelines to follow.


Climates To Avoid 

Avoid regions that maintain extreme temperatures or excessive cloudiness that may disrupt normal plant growth, the winter plant growth is directly related to the amount of daylight the plants receive for optimal growth.

If your plants can not get the sunlight they need they are subject to fail. Long periods of continuous cloudiness due to storms that restrict the natural light could easily be solved by adding some grow lights into your system to insure the plants still get the ample light spectrum that need to flourish.



A slight incline will be needed to provide sufficient water drainage.

This step  is very important.

Provide an incline in your soil under and around the gravel foundation you will be using for the base of your greenhouse.

Use the gravel to level the incline to build your greenhouse on. Greenhouses must be situated on a level gravel base from 6 to 12 inches above grade for adequate drainage.


 Water Supply To Your Greenhouse 

Plants need sufficient moisture supply for optimal development and the highest production of flowers. As to how much water is required will greatly depend on how large of an area watered is allowed that the plants can feed from.Plants all have different sized root balls make a habit of covering the entire area above the roots with water.

Installing a automated irrigation system may  be worth considering for a regulated continuous supply of water like a drip irrigation system for your plants.

Water that comes from municipal water supplies as well as from some natural sources all have amounts of impurities and could be harmful when it comes to plant growth.

You should have the water tested for chemicals that can be present or just invest in a good water filtration system to address issues in advance which may arise.


 Electric Power  Supply To Your Greenhouse 

 Your greenhouse should have an ample supply of electricity as well as a power distribution system to easily supply and manage the entire environment within the greenhouse.

Early in the designing stage of the greenhouse, you should contact your  electric utility provider regarding power availability and guidelines for the  positioning of your greenhouse. 

You may want to also contact an electrician that understands greenhouse power supplies to design the electrical layout.

Consider installing solar panels or other alternative energy systems.

This  may be a good option at this stage of the plan to save on ever rising long term energy costs depending on the size of your future operation.


 Future Expansion Plans 

 All throughout the development and greenhouse planning stages certain provisions also need to be considered for later expansion.

Before setting up your greenhouse and going into your plant growing venture, careful assessment should be made of all that is listed above before a final decision is made.
