Is it to late

Is it to late to transplant a seed that's already about 2.5 feet tall to the ground and it actually make a difference? Please and help much appreciated

depends on how much of your outdoor season remains. are the days still over 12 hours light? is the plant in flower or still veging?

It's vegging for another 2-3 weeks

its not too late if you do it soon, and putting a plant in the ground gives it unlimited root potential. The more roots it can grow the bigger it can get the more bud you get.

Its never to late sometimes its just to cold
