Hydroponic gardening offers significant benefits for those who want to grow fresh produce year-round, regardless of the weather or location.

Build The Frame

Build the frame. The frame is the foundation of your greenhouse, and it must be stable and strong enough to support both the weight of the plastic covering and whatever plants you will be growing. 

You can use metal or wood for this purpose; however, we recommend using a light-gauge steel frame because it will be easy to assemble, less expensive than lumber and long-lasting. 

If you plan on adding an automatic watering system later on down the road (which we recommend), make sure that your greenhouse has enough room at its base for this addition as well!

Cover The Floor And Walls With Plastic

As you can see, the walls of your greenhouse are made from plastic. For this reason, it’s important to choose a material that will not only be structurally sound but also protect your plants from UV rays and other harsh conditions. 

The best materials for covering your greenhouse will be UV-resistant, have low IR reflection (so as not to overheat), have good light transmission (so they don’t block out sunlight), and yet still offer flexibility in case they need to be moved or adjusted.

Add The Lighting

Now that you’ve built the structure, you’re ready to add the lighting.

Light is extremely important for plants’ photosynthesis process. You’ll need to install your lights before planting anything so that they can get used to their new environment and grow accustomed to their new home. 

If you don’t do this, they may not be able to fully develop or thrive in your greenhouse.

The best time of year to install lights is during planting season (in most places), but if you want your greenhouse up faster than that, summertime works too! Just make sure it’s warm enough outside so your plants don’t freeze when exposed directly under the sun this would kill them instantly!

You’ll also want to install timers for all of these things; this will improve efficiency by automatically turning on/off based on what time it is outside rather than manually having someone flip switches around every day (which takes up precious time).

Add A Circulation Fan

You should add a circulation fan, which will help with ventilation and temperature regulation.

Circulation fans are important for greenhouse ventilation because they keep air moving and prevent the formation of humid pockets. This also helps to maintain a stable temperature throughout the structure.

Circulation fans can be powered by electricity or solar power, and can be installed in either your ceiling or walls.

Install A Ventilation System

Ventilation is a key element in any greenhouse, as it allows you to control the environment inside. 

If your plants are growing too quickly and you don’t have enough ventilation, they will grow spindly and weak. 

On the other hand, if there’s not enough air circulation, excess moisture can develop on the leaves of your plants this can lead to mildew or even rot.

Here are some examples of different types of ventilation systems:

Passive vents: These allow airflow from outside into the greenhouse through openings like doors or windows (or even just cracks in walls). 

You should add these so that you can provide fresh air without having to actively move it around inside your structure (which could waste energy).

Active vents: This type moves air through fans located throughout your greenhouse; these fans are usually located near lights so that they’re 

Well-lit at all times during growth periods when lighting levels may be lower than usual due to cloudy days outside where temperatures aren’t as high as they would normally be during summer months when most hydroponic greenhouses operate at full capacity during daylight hours (from sunrise until sunset).

To recycle and reuse your hydroponic water, you should consider building a recirculating hydroponic system. Read our article on how to build a recirculating hydroponic system to see how this system can work for you, while saving water and increasing yields.

Install An Irrigation System

The easiest way to install an irrigation system is with a drip system. This involves laying down plastic tubing and placing emitters at even intervals along the length of your greenhouse. 

The emitters release water in small amounts, which then drips into the roots of your plants through holes in the tubing. 

You should also have a large water reservoir such as a barrel or rain barrel connected to your main line for emergency watering if you don’t have rain for long periods of time or if there are hot days when you may need more than usual water for your plants.

Before anything else, make sure that all leaks have been fixed on any pipes going into or out of your greenhouse. The last thing you want is to over-water because there was some leaky hole somewhere!

It’s important not just how often but also how much water goes into each plant container as well as into the soil itself because too much can cause root rot while too little will cause wilting due to dehydration.”

Choose The Right Medium

When you choose a hydroponic medium, there are a few things to keep in mind. First and foremost, the medium should be porous and lightweight so water can flow through it (soil-based growing offers much more resistance to water flow). 

In addition, the medium should be easy to clean and reuse it’s usually only good for one crop before being tilled under or replaced.

Finally, it’s important that the hydroponic medium is rich in nutrients so plants can grow strong while they’re maturing.

Plant Your Seeds Or Transplants

If you have seeds, plant them according to the instructions on their packaging.

Transplanting is more difficult than starting from seed. You will need to keep your transplants moist and warm until they are established in your hydroponic greenhouse or cold frame.

This table provides some useful tips for planting seeds or transplants in your greenhouse. These tips can help you get the most out of your garden by planting your seeds or transplants properly and promoting healthy growth.

Water Your Plants Properly

Watering your plants is just as important as the nutrients they take in. If you have a drip irrigation system, you will need to manually water your plants. If you are using a hydroponic system, you will also need to manually water your plants.

If your greenhouse has an automatic watering system, be sure to check it every few days and make sure there is enough water available for each plant that needs it. 

The last thing anyone wants is for their greenhouse garden dying due to lack of proper watering!

Manual watering involves checking up on each individual plant every few weeks and giving them more water if needed (you may find yourself doing this daily). 

This method can be tedious but does allow for greater control over how much moisture each plant gets compared with an automated option which tends toward oversaturation in some cases.

Keep Your Greenhouse Clean, But Don’t Go Overboard

A good rule of thumb is to clean your greenhouse regularly. It’s important to keep the glass, fans, and other equipment free from dirt and debris so that these parts don’t get clogged with debris or algae. 

But when you do clean your greenhouse, don’t overdo it. You don’t want to damage your plants or disturb the roots they’re growing in by using harsh chemicals or too much water at once.

You should also avoid using cleaning products that have bleach or ammonia—they can be very damaging to plants as well as humans! 

Stick with natural products instead like vinegar (make sure it doesn’t contain alcohol) diluted in water; dish soap; baking soda (which is great for getting rid of smells); hydrogen peroxide; rubbing alcohol; lemon juice; tea tree oil diluted in water; apple cider vinegar diluted in water; castile soap diluted in water (this one seems counterintuitive but it works really well).
