Maybe if it is totally air tight. You are really stacking the odds up against yourself. It is recommended to start planting seeds in Oct/Nov in cool/mountain NZ and you are trying to grow them in winter. More chance of a good crop when the conditions are with you than against you.

Check the plant day and night for grubs.

A few tips on growing tomatoes - make sure you have good rich prepared soil. Dig a hole 50cm deep and 60cm diameter. Put compost/manure into the soil or a hand full of fertiliser and mix it in. Plant the tomato in a bit of a hole and as it grows fill the hole in. Give tomatoes a good deep watering. Too much N and you will have a lot of leaves and little fruit. Too little fertiliser and you will have a small plant and a little crop. The secret is to know how much fert to put on and when. And start with a good strong seedling.

I live in Omarama & do very well with Sweet 100 & Money Maker in my tunnel house, just be aware of late frosts & cover. Use plenty of tomato fertilizer & a good all round compost & potting mix.

Go to a nz seed selling website and compare different tomato types. Then pick one or two and try them. Or go to Bunnings or a nursery and ask.

Lyndall, Flowers not producing fruit could be due to too much water. with regard to the height, last year I let all the side shoots grow and that stopped vertical growth compared to this year where I have religiously trimmed out any shoots from the leaf joints and my plants which were planted 23 November are between 1 and 1.4 metres high. My theory is that if you let the side shoots grow a bit it will stop trying to grow vertical because the plant needs to keep flowering and the only way to flower is to produce new growth. This growth comes from the main stems or new stems nearer the bottom of the plant. I have 4 plants so am going to let to bush out more and keep 2 growing vertical. If you let the plant grow up through the wire the possums will do the trimming for you.
