Thanks Billy, really useful

What does "determinate" mean? If I do plant a tiny tim plant, do I have to re-plant it every year?

Currently, I have put a few tomato seeds in a seeding tray (couple of days now). Do you know how often I need to water the tray? Also once I have seedlings, how do I transfer them, is there any distance I have to maintain when replanting the seedlings? I plan to grow them in pots since I don't have enough space

Thanks for all your help so far, really good
