I've searched and read many (almost all I think!) post regarding trellising veggies. Maybe too many and that's my problem- all that information is now all mixed up in my mind!

I'm new to gardening this year. I built a raised bed to experiment with SFG. The bed is 12x4- built 18" deep, filled about 12" deep (expect some shrinkage as base has straw, leaves, compost, etc.)- I know I'll hear some slack about the depth- I wanted to go to a 'sitting' height and the ground beneath used to be home to a garage that was torn down and then the area filled with gravel- nasty grounds but it gets sun!

I need to put up a trellis.

I am leaning towards a PVC trellis- Using 1" PVC, 6' tall 4 'wide, using threaded elbows-(so that I can disassemble and store for winter)-and threaded T near bottom to put another 4' wide piece in for added support. Planning to use netting I've ordered, plan to do 'weave' around pipes. Also was going to sink a piece of 1 1/4" PVC down into soil/ground and then plancing the 1" trellis pvc into that to ease in set up. This will be for tomatoes. Will this work? Support wise? Should I consider conduit instead?

I was/am interested in the T Post as supports- I bought 2 T Post at HD for like $3.35 each.. then when I was looking at them, I was like how will I attach string, wire, net? At Lowes I found T Post with holes and the 'nobs' were slanted- like it could hold wire or net and I could run string through the holes between two post. (Have now determined these are called U post) So I took the ones back to HD, bought the ones at Lowes. THEN I was thinking that 6' post wouldn't be enough, as I'd need to sink it into ground, and I'd like 6' for the tomatoes. SOOO, I took them back to Lowes and headed to TSC- as online they showed 8' post. Well they only have up to 5' U post, so I decided to wait and rethink it through.

Not even sure I could sink the post into my ground- I could inside the raised garden I suppose. But at most I'd only have 4' of the post-

Could someone give me a better idea of set-up using U post (or T post).

TIA and just wanted to say that this site is great! Nice to have a place to go to seek the knowledge of others...
