Just like growing Tomatoes?

How different are tomatoes and weed in regards to growing the 2? Would you say that if you can grow a beautiful tomato plant outdoors, in a pot with soil, that you could grow the weed indoors in soil pretty much the same?

I would say that the general horticulture skills would indeed overlap.

growing weed isnt as complicated as every1 makes it out to be, a little reading + common sense goes a long way, in fact i think in some cases tomatoes would be more difficult,

Sometimes, they both need cages.
