GrowCNanswered grow question 3 years ago I would move to a larger pot right now. In the future I would plant your seed directly into the final pot size. Since auto's are on a fixed schedule any time lost to transplant shock can affect yield.
I have done some grows in 3 gal (11 liter) pots but I get larger yields with 5 gal (19 liter) pots. Key is to water thoroughly so every bit of soil in your pot is moistened so the roots grow to use every bit of soil.
