Moving plant from out to in question

My plants have about 2 weeks to go before harvest and the nights are starting to dip down into the low 60's....would there be any advantage to moving them in to my grow cab for the remainder?...Also are there any other things I should do while doing this...Do I have to match sunrise/sunset exactly?....Would they benifit from even MORE darkness in the box?...any other special precautions or ritualistic atonements would be appreciated.

my evening temps are in the low 50's. my plants are fine. makes them turn purple.

welcome to the forum. NO. Low 60's will not hurt the plant. Unless its a potted plant and you just want to move it. Yes if you do you should try to match the current sunrise, then set your off time for 12 hours from then and leave it there til maturity. No special obescience is necessary. You will have to 'rain' on the plant and water it. VV

Thanks...I think I'll leave them since the 50's are ok! I've got a mother in the box on 18/6 anyway...
