Hi Kara I'm Charles and welcome to our group. As far as PVC goes I have seen soom on you tube. I do know one thing about PVC. A PVC mailbox post will give under stress in very hot months. Most GH with PVC are very small. To control cost I would think about starting with a 16x16 and then adding more RIBs later to expand to 32x16. Check on the price of alum. electrical conduit at Home depot. It will be much stronger and it can be bent with the right tool to shape your GH. Either way if you construct you own, be sure to support it with up-right supports. Store bought units may be designed where they don't need them. They are engineerd in that way. Good luck

Thanks Denise! A lot to sort out.

Make your greenhouse with roll up walls and doors on either end. Heat is a big problem here. If you use PVC pipe structure make sure you put duct tape over the pipe where the plastic touches it. A greenhouse manufactorer told me that the greenhouse poly reacts with pvc and will void the warranty of the plastic. The plastic 4 mil or 6 mil sold in hardware stores rarely last for more than one season and is a pain to work with or cleanup once it gets brittle. Atlas Greenhouses or Mega greenhouse superstore are good places to get 4yr. greenhouse plastic or film and supplies. Greenhouse film cost alittle more but lasts much longer, out weighting price difference. If you have access to any old trampoline frames you can make a pretty strong greenhouse frame by remixing the parts. Trash to treasure. I had my tanks and beds in the open until Decemeber. Storms excess water and frost caused issues that had to be dealt with. If you are interested in the trampoline design. Contact me and we can email each other phone numbers. I can better explain how to build it. Most Trampolines are about 12 to 14ft wide are you set on 16ft? I have an arbor build from a trampoline that has been in my yard for at least 15yrs. Hope this was useful.

Hi Everyone! Thanks Denise for pointing me to this group. I'm located near Athens and we are starting an aquaponics system in the next month or so. We are currently trying to figure out what type of greenhouse will be best suited. We are on a limited budget so we planned on doing a 16 x 32 pvc pipe structure but now are rethinking that. We are concerned with the heat in the summer killing our plants if we don't do a greenhouse with ventilation but we want to make sure our water tanks are protected. Any ideas would be very appreciated!

Hi Charles. Just like building a house. It looks totally different when the interior walls go up. I posted some pics. today. I had problems doing a photo album. I finally just put some under photos. Hope you can find them.  I found yours under all and group. I can give you some advice on sump tank install if you would like.  I had a few problems with hydrostatic pressure before I got my greenhouse up. I used to do garden ponds.  Looks like your site is very close to some major power lines.  Are you concerned about arcing on windy wet days?  Picture probably giving optical illulsion.  Hope to see more as you construct it.

If a 28x96 greenhouse seems too small, you need to tell the seller to send the other  half !!!

Charles, I am trying build some solar heaters right now. I am interested in some of the things you are designing solar. I would like to use as little electricity as possible. I bought my greenhouse used so I went with the width I needed and length was what was available. I thought it was going to be huge.... but now that it is up it feels much smaller.  I am thankful for helpful ideas and hope this group can get to know each other and work together.  I hope to upload some pictures of my construction soon.  I have very slow internet service so sometimes it is difficult to upload pics.

No com-problem, (in spanish) all are welcome and all are needed. I have changed my plans to a 20x32 greenhouse. Can't wait to get cauth up with you guys. It looks like I entered a race without a car. I plan to air heat, water heat the fish tank, overhead lights and fan cool all with solar. I'm thinking of water cooling the fish tank in the summer. A long way to go ... Thank all of you for your being there for others.

Hi Denice and Charles.Charles, your Warner Robins roots are haunting you. I live in Warner Robins, as does Randy, And Denice is from Newnan so it looks like your group is going South on you! That's not necessarily a bad thing. Denice, you are bold, starting out with an operation that big.I have been doing this almost 2years. I'm not an expert but if I can help I will gladly.
