As a matter of fact you CAN travel with plants but you are smart not to risk it.
It was recently pointed out to me that one way to go about doing things was to just go 12/12 the entire grow... granted, the plant will not show sex until it is ready either way. This method was suggested because I have a bunch of F2 seeds and want to find a good mom without taking up a lot of space... it is not meant to produce high yields of buds, just enough to tell which plant is worth hanging on to. You could always do that... But yeah it totally sucks feeling like you are pushed for time. How long do you have?
I personally... knowing me... I'm not that bright sometimes... would be concentrating on taking very good care of the plants that are going now, getting a bunch of healthy clones rooted, taking those to my new place, and setting up shop the moment I walked in the door. But that's just me. It sounds like even if you put them on 12/12 now you will still n ot have time to finish?
