Optimize Your Greenhouse For A Great Growing Season

Optimize Your Greenhouse For A Great Growing Season

Modern greenhouses seem to be incredible growing machines, not merely structures that allow you to produce outside and extend the regular growing season in the area. Modern greenhouses could include numerous automated moving elements. The amount of automation you choose to implement into your urban greenhouse setup is entirely up to you and your budget.

Interestingly, many do-it-yourself, inexperienced greenhouse owners devote significant time, effort, and money to constructing a building but neglect studying how to properly equip their urban greenhouse with the necessary equipment to imitate an optimal growth environment. 

This article will show you how to avoid building suffocating hot boxes that harm the environment and impede or perhaps even destroy the plants you're attempting to nurture. 

Building a Greenhouse for the Growing season

Optimize Your Greenhouse For A Great Growing Season

Here are some of the most crucial things one must take care of when building a greenhouse:

  1. Location and Sunlight: Optimizing the quantity of sunshine that can reach the plants is crucial to getting the most out of an urban greenhouse.
  2. Having stable ground: A solid foundation is essential for success in everything, especially construction. 
  3. Weather conditions: Apart from natural calamities, the cottage greenhouse must be able to withstand even the most extreme weather.
  4. Space Utilization: The frame material you pick will determine the strength of the cottage greenhouse structure. It is critical to consider the gauge and the diameter of steel utilized in your greenhouse structure.

DIY Steps to Optimize Your Greenhouse

Here seem to be a few steps and greenhouse ideas that might assist you in making your initial greenhouse a "growing" success to get you beginning in the correct direction.

You will also have bigger yields with less effort when you understand these different features and how to tune them all in harmony to make the most optimum growth environment for the plants.


Finding the ideal inclination for the arrangement of your greenhouse is an essential technique to ensure that your Victorian greenhouse receives sufficient sun throughout the day. If you are growing in a traditional wrought iron greenhouse, this usually means orienting it east to west so that the sun can track the full length of your greenhouse throughout the day.

With an outdoor light-deficient wrought iron greenhouse, on the other hand, it's preferable to angle the greenhouse north to south to decrease the amount of shade cast by the blacked-out end walls & fixed system. 

You'll also have to familiarize yourself with your plants' natural growing environment. Next, you can figure out what accessories you'll need according to the climate you’re working in to ensure you're setting the perfect atmosphere for the plants.

Stable foundation

The pad arrangement for your greenhouse construction is the first step toward laying a solid foundation. You'll need a flat pad with suitable drainage for water runoff on the parcel of land where you'll be putting the building. When proper drainage is not considered, you will end up slogging through a marshy mess during the rainy season.

Whenever it comes to foundation design, there are various options available, ranging from soil to concrete to rock/granite. Whatever your requirements, there is a solution.

Cementing your ground pillars at least two inches into the ground is advised for the strongest structure. You can opt for a soil leveling pad, concrete footings, a rock backfill, or raised beds.

Framing material

Your greenhouse frame must be composed of steel that meets the county's requirements. Further wind bracing for the greenhouse's side walls will assist in spreading the structure's weight and stabilizing it.

End wall framing is among the most critical parts of a glass greenhouse structure. End walls are subjected to the most wind pressure, so ensure that they're well-framed and fastened. 

You also might want to think about trussing. Trusses will span the length of your glass greenhouse, with one at each bow in most cases. These are useful because they provide ample room for hanging the additional items that help regulate your atmosphere and a lower point from which to hang any supplemental lighting which may be introduced. They could also assist in the weight-bearing process in locations with a lot of snowfall.

Roof Arch

Depending on the location, a specific pitch/angle to the glass greenhouse's roof might be helpful. Many people recognize a greenhouse as a Quonset hut with a half-circle roof. A semi-gable or gothic-arch greenhouse may be preferable in high-snow areas.

Poly covering

Many types of poly covers are available these days, and it's crucial to know which is ideal for the situation before making a purchase.

However, how does greenhouse poly vary from the plastic sheeting available at Home Depot?

The most significant feature of a poly coating is UV protection. Plastic degrades quickly in the sun and under normal weather conditions. Ensure the poly has already been coated to withstand UV radiation, so you don't have to replace it each month. 

The light-diffusing poly could be helpful in a greenhouse if light deprivation is used. The blackout system would likely cast partial shade on a section of your greenhouse at a certain point during the day. Light diffusion characteristics in the poly covering would help scatter and disperse the light that comes in.

Anti-drip polymers are now available to help in internal condensation and prevent water from falling on your plants. This one will aid in the prevention of mold and mildew.

When it comes to appropriately investing in the greenhouse, the poly textile strength is possibly the most crucial factor. You wouldn't want a thin sheet of plastic that rips off easily.

Consider the local winds, whether you have trees on your land, and any loose debris which might pierce your covering. Some woven polys can withstand 80 pounds of pressure per square inch before breaking.

Stepping stones that are strategically placed

Using properly placed stepping stones in the beds might help you enlarge your planting areas. This way, you won't have to make room for any additional paths save your primary road.

You might stand above your plants with two tiny stones, one per foot, based on the height of your plants. Utilize one larger stepping stone that can fit both feet for taller plants. 

Arrange enough stones close together so you can easily step from stone to stone while avoiding hurting the plants. These stones also serve as mulch and heat sinks, keeping your plant roots warm in the winter.

Greenhouse insulation

You'll need the means to winterize the greenhouse for energy conservation if you're growing plants during the typical growing season. When utilizing a soft poly covering, the ideal technique to insulate the greenhouse would be to get a second layer with translucent poly film and an inflation blower to inflate a bubble of air between the two layers.

A further alternative is to use strong poly panels to cover your frame. You could obtain hard polythene in panels or rolls, or you can get polycarbonate. This is the best option if you live in a location where the weather is cold and there is a lot of snowfall. These double-paned stiff poly panels provide the insulation needed to keep the hot air inside and the cold air outside. You could grow during all seasons if you get a heat source with excellent insulation.

Greenhouse ventilation and airflow

Temperature management & clean air exchange are both dependent on airflow. However, if a CO2 generator is installed, there will be insufficient CO2 for photosynthesis. If you have a generator, fans will be required to circulate air throughout the greenhouse to prevent fungal illness in the plants.

Fresh air could be exchanged and circulated via vents, exhaust fans, and even oscillating fans. You could also install roof vents that open and close depending on the day's temperature. Roof vents are frequently operated by hand; however, they can be automated with just a thermostat controller to remove the need for human intervention. 

Exhaust fans could be set on a timer to alter the air as frequently as once every minute. If it's chilly outdoors, you'll want to replace the air less often, perhaps once or twice an hour. You may also connect your fans to a thermostat so that air is exchanged once the temperature rises. Install those fans up on the end walls, with a protective hood to prevent rain from blowing into the greenhouse.

Within the greenhouse, you can install ceiling fans or oscillating fans to keep the air moving. This would regulate humidity levels and stimulate your plants' stems like the wind does outside.
