Question about transplanting a plant

I have a plant that is about 5 weeks old and in a relatively small pot (I think)

So I went to the local grow shop and bought some soil and a larger pot and I am going to move her to the new pot sometime in the next couple of days......

.....any advice? Anything I need to make sure I do or dont do?

Thanks.

make sure you get a pot big enough to finish the plant in transplanting is stressful and reduces growth rate if dont improperly. so make sure you only have to do it twice. other than that your prolly good.

try not 2 damage the roots....
if u can manage 2 gt the entire contents of the pot out it will work the best.... this way the roots r not damaged at all
