Hey! No sweat. I do this for fun. May it be the worst thing that happens to either of us. But going from sprout to 5 gallon pot will definitely stunt growth. I sprout in peat plugs, put the plugs into solo cups. When the growth in the cup overlaps the edges of the cup, I transplant into my final medium, I use 3 gallon and see a slowdown for a few days, in five gallon it will be real slow. At this point, I would transplant into 2 gallon and hold my breath.
