hi all. i'm trying my hand at growing tomatoes (early girl and grape) in plastic pots this year. they're coming along quite nicely so far but it seems that i made a a beginner's mistake. they are planted in 3 gallon containers and it seems that most people agree that 5 gallon (or bigger) should be the minimum size used.

would it be beneficial to drill large holes in the 3 gallon containers (bottom and sides) and place it in a larger 5 gallon container with soil? it sounds as though completely removing the pant from its current home would be a bad idea as that seems to often stress plants. any advice would be appreciated.

thx!
