Best things to plant my seedlings tomatoes in?

[Readysetcake]

I’ve started tomato, cucumber and courgette seeds off inside and they’re growing well. I had an old green house last year but we got rid when we did the garden up to sell the house. Looks like the house sale probably
Won’t go through now (sob!) so I now have a garden with nowhere to plant out my seedlings. What do people recommend for the above? Lots of grow bags of will pots be ok? If so how many plants can I get away with in each pot? Thank you!

I used black buckets with holes drilled in them for drainage. 1 plant per bucket.

You can get tomato grow bags, 3 plants bet bag. They are quite shallow though so I cut the bottom off decent size plant pots and pushed them into the grow bag and grew them that way.

I cut the bottoms off 2L plastic bottles and pushed the neck into the pot for better watering.
