That is so true
That is a good size tunnel you have. If me, I would definitely go for a hot bed rather than a Prop. ( or 2 or 3 ).
If simply for raising plants, my feeling would be for an independent hot bed at staging level. Easier to insulate for one thing plus you can keep pots of stuff on there when not using or to boost the bottom heat of seedlings you have grown and pricked out. Cuttings too are easy to do.....don't need to put them in pots, just straight into the soil/compost.
Do I sound biased ? Just a bit I guess
Be interested to hear what you decide and how it works out
