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.

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.

More information is needed: for example amount of water... soil conditions. The MOST GENERIC, and probably most correct answer is LACK OF NUTRIENTS. Most people plant their plants (tomato) adding lots of compost and/or manure at the time of planting. The plant grows using the nutrients (some are washed away... maybe trees manage to confiscate some nutrients); but as the soil nutrition drops, the plant, still wanting to grow, starts to take nutrition from its lower leaves so it can grow leaves higher up. That is, it is deciding how to best used it's own self to maximize it chances of success; since it can't source the needed nutrition from the soil What you need to do is: ADD manure or compost or anything else you may have to put nutrition back into the soil. I rinse my coffee pot in the garden, I also try to drain things (like the water from soaking dried beans) into the garden. Manure/compost/nutrition (in any form) needs to be added at planting, middle of the season, and close to the end of the season to give that LAST burst of energy to bring the fruit/vegetables into full form. Don't feel like you need to spend a lot of money; get creative; in Canada we can stop by our local coffee shops and pick up the days used grinds for use in our gardens (free); you can add micro nutrients to your garden by filling a pail with water and adding a layer of rocks (rocks are minerals) stir and use this to water your plants. Left over tea bags, left over coffee grinds, stuff that you might rinse down the sink (food juices), blood from meat when you wash it before cooking it ..... anything like that all puts nutrition back in the soil.
