Hi l am looking to construct a green house / high tunnel I like your hoop bender I have most of the hoop lumber I need cover ties
Are you looking for paracord to keep your greenhouse plastic down?
1-3/8" top rail seems a good material to use. I've seen 1-5/8" top rail as well. Would these benders accommodate that diameter?
The benders work with 1 3/8" top rail to bend the hoops. The 1 5/8" pipe is used as the ground post, which gets driven into the ground and the 1 3/8 sits in it.
WITH YOUR BENDER IS THERE A WAY TO GET STRAIGHT SIDEWALLS?
There is not a way to get straight sidewalls using the bender.
How many hoops are needed / how far are they spaced? Say if I wanted a 20 x 40' house, how many of the 10' poles would I need to purchase?
We reccomend spacing the hoops 4' apart. Each 20' hoop will require 3 of the 10' top rail poles. If you would like to view all of the required materials to build one of our DIY kits that use the hoop bender you can scroll to the chart of what to buy locally at the bottom of this page. https://www.bootstrapfarmer.com/pages/diy-greenhouse-kits
I’d like to make a 20’ wide hoop house with 2 foot ground posts. Height would need to be 6-8 feet ideally. Which bender would you recommend?
We recommend using the 20' pole bender. The height of this structure would be 10.75' tall.
When will you have more of the 20’ benders in stock?
We expect to have those available in the beginning of March.
I have access to 20 ft 13/8 top rail. Can this be used instead of 2- 10ft and work with the 12ft wide bender.
While we haven't tried this with the hoop bender ourselves, we have had customers that did this without issue.
Hello. Do you have a bender that can bend 1inch Galvanized pipe?
We dont have any greenhouse pole benders for 1" pipe. The closest would be the 10', 12' and 20' benders that accomidate 1 -3/8" pipe. These would generally work but there will be extra space so you may get uneven bends.
What is the inside height of the 6’ wide hoops?
The height would be about 3' tall plus the height of your ground posts.
What’s the roof height of the 12ft wide option? We’re looking at using this to bend 20ft EMT sticks, that’ll ultimately be attached to 3ft vertical walls (goat & pig housing).
If you are building a greenhouse using a 12 ft bender AND ground posts that are 2ft above ground, the height of the hoop house will be about 8ft tall.
I'd need a 24 foot bender
We do not currently offer a 24 ft. bender. Due to the extra support structure needed to brace a hoop house over 20 ft. wide we recommend adding length vs. width to your build to increase available space.
Hi there, any chance you might be making a 4 ft hoop bender in the near future? It's the perfect size for raised garden beds. Thanks!
We're workin on it :) Next gen hoop benders + additional sizes coming later this year.
I have 21 foot top rails can I been two of those to make a 20 foot wide
You would need to cut down one of the 21 foot top rails to 10 feet. Our 20' wide grenhouse pole bender has an angle based on bending 30 feet length of pipe.
I have 20 foot lengths of 1.25 in. galvanize fence tubing. I want to bend these to make a 12 foot hoop for a chicken run. will your 12 bender work on this pipe?
While the 1.25" tubing will fit in the bender, it will wiggle around a lot and you may not get a very nice hoop shape. In order to make a 12 ft wide hoop with our 12' bender we use 1 3/8".
on a 24 foot wide hoop what is the length from foot (base) to foot (base) for the width of plastic film required?
48' wide will work and will leave just a bit extra for sidewall ventilation
Hi, can I use 1” emt conduit for a 20’ greenhouse? And also would you sidewall ventilation crank work with a 20’ greenhouse built with these benders?
Are you looking to use 1" EMT for the hoops for for the roll up sides? 1" EMT may not be strong enough to use for the hoops. It can be used for the roll up sides however it would not fit our hand crank.
Our sidewall ventilation crank would work with a 20' greenhouse no problem if the EMT was 3/4" for the roll up sides.
I have a 34’ wide greenhouse gothic arch I want to duplicate DIY. Do you have hoop benders for that style.
The largest hoop bender we currently have is 24'. Unfortunitly we don't currently have 34' wide.
Can I build a 10' hoop house with the 12' bender?
Or build a 12' hoop house with a 10' bender?
I want to build a 10' and 12' hoop house.
It isn't reccommended to do either one since you will risk having the hoops mishaped. With that said however, using the larger bender to make a smaller hoop house would be the lesser of two evils given that you could potentially squeeze the hoops together a bit when placing them into the ground posts to create a smaller width. Doing it for 1 ft of width difference may be okay but 2ft may be pushing it. I definately wouldn't use a smaller bender to make a larger hoop though.
Can the 6ft bender do 3/4" emt.
Yes it can.
how many 10' 6'' toprails are required to make a single arc for a 24 foot wide greenhouse?
For a 24' wide hoop house we would bend 4 - 10ft long poles to create a single arc.
We received our hoop bender. There is a loop/slot at both ends. Videos show it at only 1 end. It seems like the loop at other side would interfere with bending. Is it defective?
Only the 6ft bender has two slots. One is for if you are using 1/2" pipe and the other is if you are using 3/4". For our other bender sizes we use only 1 size (1 3/8") so only 1 slot is necessary.
My driveway is 10’ wide. I want to build a tunnel for car and grapevine. Can i make it 9’ wide and 12’ tall tunnel with this tool?
You can make that work. It might be little bit of a struggle to get the hoops to slide into the ground posts, but you'll still be able to get it done. A taller tunnel requires taller ground posts, so instead of cutting an 8' pole in half, leave it at 8 ft and put 4 ft down and leave 4 ft up to get a bit higher than the usual.
It says made for 3/4” conduit on the 4 ft bender. Could you also use it for 1/2” conduit?
Yes it can. It will be a little looser in the guide.
Gothic hoops? Do all of these work to make gothic style hoops or is there a special hoop bender just for that style?
Our hoop benders are designed for making round hoops not gothic style.
I have a 20 by 20 by 12 ft high need hoops cover wiggle wire and rail for the cover
You can double check my math and reference this article for meausring: https://www.bootstrapfarmer.com/blogs/building-a-greenhouse/how-to-determine-the-size-of-greenhouse-plastic-you-need?_pos=1&_sid=cc67bc342&_ss=r
I want to have a 10 ft wide hoop but I don’t want it as tall due to constraints in our neighborhood. Could i use 15 ft of top rail instead of 20 ft of pipe and if so, which bender would work best?
We don't recommend doing this as the benders are specifically designed to bend 2 pieces of 10' pipe for the perfect circumference.
What width agribon do I need to cover the 4’ and 6’ hoops?
You need to purchase at least a 10' wide piece, as the pipe use to bend the hoops was 10' long.
