Pressure treated timber for DIY greenhouse

redser7

Hi, I'm just at the initial figuring out stage of this project. Just wondering if anyone could advise me on the size of timber I should use. 4 x 2 or would 2 x 2 suffice? I'm on a very tight budget so after checking out prices I'm hoping someone says 2 x 2 will be fine!
The basic plan it to erect a simple enough 6 ft cube plus roof (not decided on the design of the roof yet). I'll be using heavy gauge polythene panels for the walls, probably out of 2 x 1, which will sit into the outer frame.
The enemy of course will be wind, but with cross-bracing I'm hoping 2 X 2 will do the job.
Thanks a lot for any advice

Anyone? Please? Even if you have no gardening/greenhouse experience I'm basically wondering if you could build a small sturdy structure from 2 x 2 treated timber.
Cheers

16 foot length of PT 2 x 2 is 4 euro 64 cents per length

16 foot 3 x 2 is just under 10 euro.

Heiton Buckleys or Chadwicks.



You could build it from 2 x 2 but you woud need to brace the fcuk out of it.
3 x 2 would be sturdier but heavier too.

Id go with 3 x 2 if I were doing it myself.
Treated Decking screws for screwing the frame together.

Pic of 2 x 2 siting beside 3 x 2 for you to compare.
