Sweet Dumpling or Ute Squash in polyhouse or on ground outside

[Hector]

Do you think I am being ambitious trying to grow either three Sweet dumpling or 2 Sdumpling and one Ute upright with canes and net in a 18foot wise end of a polyhouse?

Many Thanks

I grow my squash outdoors over an old polytunnel frame, but they do need tying in and support. I have grown quite large Red Kuri successfully this way, the smaller pumpkins do well, this year Munchkin and Bubble and Squeak. I've never tried them in a greenhouse but see no reason not to, except the foliage will act as shading for anything else you have in there?

Thank you :)
