  1. So, so grateful for the plans.

  2. I appreciate your intentions to help with greenhouse plans, but really these are
    pictures with little or no details- there are no plans attached.
    Would you mind changing your page to include plans ??
    *
    I am most interested in the first design showing the 1. HOOP Style greenhouse;
    but would like to see more explanations of the plans.
    Such as : -where to put the rebar ? – what are ‘hoop stands’? – a ‘lathe’ in english is a machine, what do you mean ? – put ‘pvc’ at the top ??
    *
    I know you mean to help, but explanations are supposed to answer questions, and not raise more questions if everything is explained correctly.
    Thank you for your time?
    I hope you can answer my questions, you have a good design shown in # 1. above.
    Cheers,
    Gk.

    • You can view the detail of each plan by clicking on each image source As I mentioned in the first paragraph.

    • A lathe is also a name for a thin wood strip also called a fir’n strip ( for its use in tanning hides ) but that’s more useless information for you on that set up you need a 1/2 in drill bit for wood and pvc pipe i used 2 – 8′ per hoop with a T coupler or a 4way coupler X= as many as you want.

  3. Great list of plans man, I have been in this industry and teaching people to build greenhouses, and recommending resources such as the one’s above, for over 6 year’s now.

    I have to say, that this is a top notch post, and you did a really good job of showing how people can make some extremely unique greenhouse models and styles.

    Keep up the good work, and I will continue to read you’re blog, I enjoyed this one very much. I’d love to write for you, or allow you to write on one of our many highly popular greenhouse and gardening website’s, I promise that you’d be interested in getting you’re name out there, through our 10+ year established network.

    Talk to you soon, thanks.

    • Thanks Whitney for your compliments!You are doing an excellent job,I’ve seen your website,you seem to be very knowledgeable person about green housing;I would like you to write about green housing on my blog.You can contact me at Hafizfarhanahsan@gmail.com.

  4. Wonderful DIY project ideas. Thanks for sharing with us.

  5. i like the one with the pvc pipes that you put into the ground. im going to build one soon on my smallholding. I was wondering if it will be strong enough to withstand strong winds?

    • Wind can do some pretty interesting things to plastic. If you live in an area with high winds and the pvc greenhouse is exposed to those winds, you might find it very useful to take a length of soft rope and criss-cross it over the top of the plastic to hold it against the pvc pipes.
      In high winds, greenhouse shapes sometimes work as air-foils (like plane wings) and tend to lift the plastic right off the frame. Running a criss-cross pattern of rope or twine down the length will reduce this tendency.

  6. Even though they are a bit more expensive than vinyl wraps and glass, pvc panels are an excellent solution for building greenhouses. They’re incredibly resistant to damage, fire and weather, making them a tremendous investment for your greenhouse hobby.

  7. LOL, the old PVC greenhouse. Conceptually fun and well meaning “designers”, however PVC is not UV protected so a greenhouse of this kind of construction will only last a couple of years, hardly worth the effort or expense. Build it right, once.

  8. We are looking for varying sizes of waffle fiberglass panels we can use for the glass areas in our greenhouse? Can you help with a potential resource? We are wanting to incorporate it into our wood frame construction. Not corrugated but waffled for more strength.
