Oh, and the rule of thumb i have been told is 1 gallon per every 12in. of expected final height. so u should be good on the 5 gal. I have heard that it is better to start out in smaller containers when seedlings/clones so the roots don't have to travel so far in the pot, but a little late now. I have also heard of people just starting in their final pots so I don't know if ir really makes a dif.
Good Luck!:weedpoke:
