No transplanting and pot size

Is 2.5 galon(10l) pot enough for Short stuff auto assassin on the homepage it says Height : 20 – 30 inches. And can I out the seed directly into the pot where I am going to grow it all the time or should I let it build roots in some smaller pot?

if its a auto start in the finishing pot you want lil to no stress with them imo i would go with a 3 gal

its all personal choice that can be effect by many things. but i go straight fro there germination cubes(root riots) straight into 5 gallon post where they stay till chop.
