Thought some of you may be interested in watching a greenhouse go up.  Hershell is building this one at an elementary school in northern Georgia.  Started Monday afternoon and will finish Thursday or Friday.  Hershell has been sending me pictures of the build for my upcoming greenhouse project.  

Looks a bit foggy...this is where it starts, sorry no pics of the first steps.  The main structure is up, bows on and purlins (chain link fence top rail) are in.

   
These are the brackets that attach to the purlins and the twinwall plastic will screw down to them.

 
Twinwall going on the end wall.

Exhaust fans installed

And the outside vent wall


 

The cooling pads being installed

 


 

The irrigation system going in

 

The next set of pictures is how they build the tables.  Hershell told me the crew can make a table in 3 minutes:)

The basic frame made out of F channel...I think it is called.

 

Cross pieces are 1x2?  tubular steel and the channels that run lengthwise are???  


 
Legs installed

 

 and braced.

 

Finished product except for the sheet of expanded metal.
    
This is a different greenhouse he built a couple weeks back but shows the finished tables.


 

Any questions i'm sure Hershell can answer them.  Just hard for him to post the thread while on the road.

I have to say that twinwall is amazing stuff.  Goes up easy and it is strong.  

Nice,
What is being used for summer cooling?

Thanks for posting those pics, Wills.  Those greenhouses are huge and they look well-built.  Is the elementary school going to grow its own food?

Steve,

I'm not sure, think Hershell said it was a federal program???  Or I could have just assumed that.   My bet is food and education.  So many kids these days just think food comes from the grocery store.

Wow! Thank you for posting these photos, Wills.
I need one of those.

I took the 3 hour ride up to Hershells on Saturday.  We did a bit of a trade.  I took him up 14 1 gallon figs and brought back a Galicia Negra, Ice crystal, small Jolly tiger and small Zidi.   

 


The first time I was at Hershells a couple months back he and his brother were just making the pieces for his new personal greenhouse project.  He already has 2 36' x 100' greenhouses but his brother wanted something a bit different.  So...


You can tell he is comfortable walking on the steel :)   You can see one of his big greenhouses in the background.

 

They put 9 bales of cardboard on the bottom of the dome then mulch is going in on top.  It is 30 feet across and 15' tall.  It is made out of fence top rail......and a whole lot of it.

 

This is great to look at and dream of.
Thanks for the pictures Wills and please keep them coming.
Outstanding work Hershell

Well those are just incredible!  Thanks for sharing the process with us!

Thanks wills, without you this wouldn't be possible. The greenhouses at the schools are for education only. The most of them are built at high schools, a few at middle schools and ever so often one at an elementary school. Wills I think you got the short end of the stick on that trade , just saying. The dome belongs to dwllnet, he is going to post more on it one day. He plans to heat it with solar so it is our project for the time being.
