Moving plants before they start flowering.

Any arguments against moving plants before they start flowering? I think transporting them is not harmful if they haven't started flowering yet? Thanks.

id say its fine. and id advise moving at night. just be careful yeah.

I've got one more question. What will happen to plants if they are put on irregular 12/12 cycle; I am unable to watch them every day. Let's say I can put them on 12/12 for 1 week and then they will have to grow natural way for 2 weeks. Then 1 week 12/12. What would it be like to them ?Thanks.
