Dear Experts,

I just planted my tomatos! Here is SF bay area. I bought a growing kit
which contains a 6" bucket, potting soil and a small bag of seed.
Following the instruction, I put 10 seeds about 1/4" below the top
soil and water thoroughly. I'm anxiously waiting for the green! After
it grows taller, I'll buy a type of "backing scaffold" for its vein.

But one day when I was chatting with my coworker at lunch. He said
tomato needs a big pot! Is it true? The instruction didn't say I need
to change to a bigger pot and it promised 200+ tomatos!

So my question is whether I'm OK with the current 6" pot or should I
replant later? and when? after 1 year?

Thanks!

Tiffany
