Thank you for purchasing your Sunglo greenhouse!

Sunglo Greenhouse Tips

Now that your greenhouse is built here are a few things to help you get started-

• Have a certified electrician connect your electricity for the ventilation system, power panel and other electrical components.
• Once electrical has been connected, set your ventilation thermostat and heating thermostat at your desired temperatures.

  • Example of power panel placement (220V shown): Place the panel in a location where it is least likely to be exposed to water.

• Hook up your lights! They can be hung from the trusses for overhead lighting.

  • Example of light placement: You can drill holes through the roof trusses, place an S-hook through the holes, and hang lights and baskets from the hooks.

• Install your shade cloth if the temperature is hot outside. We suggest purchasing 6+ bungee cords and the same amount of eyelet hooks to install your shade cloth.

  • Example of shade cloth on free-standing model: The wooden foundation is perfect to hold the eyelet hooks. For larger greenhouse you can use a long rope at the corners for easy installation and removal.

• Cleaning your greenhouse-

  • We suggest cleaning the greenhouse twice a year with 1/3 cup of bleach per gallon of warm water. Using a long handled mop scrub the outside and inside of the greenhouse. Environmentally safe cleaning products can be used as well.

• Visit the Sunglo blog for information about saving energy, shade cloths, additional accessories and about greenhouse growing.
• If you haven’t already, we suggest investing in a good greenhouse growing book like “The Greenhouse Expert” By Dr. D.G. Hessayon. This will provide you with information on different plants that thrive in your greenhouse atmosphere and additional information about grow lights, plant nutrients, temperature and moisture control, etc.

• Now that you have the major things sorted out check out our “Greenhouse Gardening Basics” post to keep you moving forward!
• Find Sunglo on social media for new product alerts, company news and greenhouse growing information-

Sunglo provides for each greenhouse a manual, foundation guide, power panel wiring diagram, cedar shelf instructions, product/parts catalog and other information. Contact customer service if you would like to request any additional information.

Greenhouse Heaters – Which One Is Right For You?

Greenhouse HeaterGreenhouse heaters. Electric, natural gas, propane and many more. But which heater is right for your greenhouse? How do you find out? This is where BTU’s (British thermal units) come in. To find the best heater for your greenhouse you must know the number of BTU’s required. And I am going to show you how to determine it!

Here are a few simple steps to find your BTU requirement.

 

  • STEP 1

You need to know the surface area of your greenhouse. This is not simply multiplying the length and width. You must calculate the area of each wall and each ceiling panel then add them all together. If you have a Sunglo greenhouse click here for Sunglo’s Surface Area Guide post.

  • STEP 2

Next you need to find out the average winter temperature (outside) in your area. This is where the internet comes in handy. But I made it easy for you > Click here to view a list of average temperatures in the U.S.

  • STEP 3

Now what temperature do you want to keep your greenhouse at in the winter? This depends on the plants you are growing. You should be able to find plant temperatures online. But a common minimum temperature for over wintering is 50°F.

  • STEP 4

The next step is finding your greenhouse’s U-Value or Heat Transfer Coefficient. This is determined by the material your greenhouse is made of. For a Sunglo greenhouse we use a U-Value of 0.75. To find your specific materials U-Value > Click here for a general list.

  •  STEP 5

Now that you have completed the first 4 steps you should have –

  1. Your greenhouse surface area
  2. Average winter temperature
  3. Desired greenhouse temperature for the winter months
  4. Your greenhouse material U-Value

Now we can find our required BTU’s!

And here is the formula –

  • Desired greenhouse winter temp – Average winter temp outside  = Temp differential
  • Surface area × temp differential × U-Value = Required BTU

For example:

My greenhouse surface area is 744

My average winter temp is 20°F

Desired greenhouse winter temp is 50°F

Sunglo acrylic U-Value is 0.75

  • 50° − 20° = 30° (Temp differential)
  • 744 (surface area) × 30 (temp differential) × 0.75 (U-value) = 16,740 BTU’s

Now you can shop for a heater that provides at least 16,740 BTU’s!
