Here we go! off into flower as of tonight!

Well I am switching them over to flower tonight! here is a picture from right before the lights going out! LOL I imagine this is comparable to sending your kids off to their first day of school.. They are about 18 in. tall 5 gal fabric pots in an 8x4. might have been able to go a little longer in veg, but being my first grow I did not want to run out of room. figured this time around better to error on the side of caution! Thank you everyone for all the advice to get me to this point! Even if I was just lurking for most of it!

I think your timing is great. They will expand significantly, but not too far outside the boundaries of your pots.
Good luck!
