For a hobbyist, amateurs and commercial growers of marijuana who reside in places where seasons show dramatic shifts in temperature, humidity, and climate, growing their crops inside a post frame building or a greenhouse may be the only way they can truly ensure their crop’s health. In fact, in many extreme cases, planting inside these structures maybe the only way a grower can truly cultivate these plants.

A post-frame building is ideal for extending cannabis growing season and also for protecting seedlings from various environmental conditions. As a grower, do you know what is an ideal post frame building for growing marijuana?

With complete honesty, there is no one specific all-cure design for a post frame building. Especially for cannabis, building an ideal post-frame building depends on many factors. So instead of teaching you what an ideal post frame building is for growing cannabis, we will try to guide to help you decide, strategize and build an ideal post frame building for growing your cannabis.


When planning growing structures for your crops, make sure to build a type of post-frame  building most suitable to ambient temperature and humidity in your area. Understand there are two types of post frame buildings – hot and cold. Cold frames are structures usually built to protect crops from strong winds and rain. For countries in the tropics where climate can be either very dry or very wet, cold frames are ideal. However, if you live in a colder environment where frost can potentially kill your crops, a heated post frame building, known as Hot Frame, is most suited.


Growing a tall variety of cannabis in a small post-frame building will limit plant growth and can easily take up too much space. It is very important to plant shorter strains of cannabis ones not growing above your waist. One great type of an Indica variety is Royal Cookies (80% Indica) strain. This cannabis is well known for being short. Its structure does not spread out. Another strain perfect to grow in a post-frame building is Tutankhamon. It is a Sativa-dominant strain and is quite compact and small. You will notice how short it is after just 15 days of growth.


Create a plan for your post frame building on paper. Layout how many plants your post frame building’s floor area and its estimated height will fit. 

Cold frames are usually built to be smaller than hot frames. They are also normally set directly on the ground. Hot frames will have a heat source installed to warm the whole structure. Thus, hot frames will need a higher ceiling. As we mentioned, there is no one specific ideal type of post frame building. Do not believe anyone who says otherwise. Who best can tell you what you need but yourself? 

Follow these guides above to help assess and build your ideal post frame building for cultivating cannabis.

How Much Space Do You Need for a Grow House?

As medical and recreational marijuana has become legal in more and more states, there’s been increased interest in learning how to grow this plant. If you’re thinking of trying it out or going into the business, you might be wondering just how much space you need to grow marijuana.

The amount of space you need will largely depend on how much marijuana you plan to grow and what kind of setup you plan to use. In general, a novice grower can expect to harvest about half a gram per watt of light.

If you’re a more experienced grower, you can expect to get about a gram per watt. If you’re just going to grow marijuana for your own medical use, you may be fine setting up a grow room in a closet (as long as it has proper ventilation). If, however, you plan to grow on a commercial scale, you may need a full grow house to accommodate your plants and equipment.

What to Consider When Making Space for a Grow House
It’s important to have a plan in place before setting up your grow house so that you know exactly how much space you need. Underestimating the necessary space can lead to mistakes and limited growth, which can reduce your yield and cost you money.

Here are a few things you should take into consideration when deciding how much space you need:

  • Ventilation—Proper ventilation is key for any grow house or room, so make sure you have space to set up a system that can pull stale air out and pump fresh air in.
  • Lighting—Do your research to determine whether you want to use fluorescent, HID, or LED grow lights. Whatever lights you choose, you will likely need room to hang them from the ceiling with a hook, pulley, or ring.
  • Ceiling Height—How tall do you expect your strain of cannabis to get? Your ceiling needs to be high enough to accommodate your lights and fully-grown plants.
  • Accessibility—You should be able to tend to your plants from all sides, so make sure you leave enough room between rows so that you can easily move through your grow house.
  • Measuring Supplies—You may want to set up a station in your grow room where you can keep supplies like a thermometer, pH meter, and PPM meter.

Take the time to plan your grow house space in advance so that you can maximize your yield. Worried that you don’t have enough space to set up the grow house of your dreams? Order your custom grow house kit from Hansen Pole Buildings (866)200-9657.
