Has anyone ever made one? I'm looking for plans for a LARGE one....it would be nice to grow all the toms, chillis and peppers together, rather than have to stagger the planting.
Thanks!!

That'd be big plastic bag in my case then!

We've got a couple of 25' heated tables. Construction's pretty simple ply wood -> layer of sand -> soil warming cables ( and thermostat ) -> more sand -> cover with some of that black porous plastic matting stuff. We also have a couple of plastic "tents" which can be used to keep even more heat in , and they both ( the tents ) have a fixture for a fluorescent so we can provide more light if required, but they're in a greenhouse so we only use those *really* early in the year.

Costs quite a few pennies in eleccy to run though

Great Idea
I made mine from a coupleof sheets of ply. Gave me a 2ftx2ft box with 8" of height inside. I also lined it with foil backed insulation which I had spare from a previous job. I topped it off with a sheet of polycarbonate (good for light penetration, insulation and did not need a frame for it. 
Key things to think about are
a) How will you ventilate it  - I just lift one corner of the sheet during the day.
b) what growing height to achieve - once I had lined the base (more important than sides) I had less growing height than I wanted.
c) How heavy these can be - my size is just about liftable with sand and soil cables in it - you need some good staging to hold it on.

I like the idea of the tented tops ( thanks Yabba)  - may customise mine with 2 hinged sheets of polycarb, this will give me more height too!

Thank you chooks! Will start a plan using a combo of the 2!!

If you make the tents removable ( only one of ours is ), then you can use the benches year round

You'd also be better making them a tad more square than triangle so you gain more height at the front/back. Up until last year we've only used them for dahlia tubers/cuttings, so the height wasn't important, but this year it was noticeable when I had my early toms/chilli plants in there .. chances are I'll redo them before next year.
