strawberries and toms, question about photoperiod in fruits and veg indoors

Ive been an outdoor vege gardener for long before i got into growing MJ and i have lived on the coast most of my life so outdoor growing was easy except in the middle of winter. Ive moved inland to a colder climate so have decided to give my MJ some room mates. I have some tomatoes and strawberries at the moment and am germinating some spinach,capsicum and basil.
My question is about changing photoperiods with any of these plants. I have had the flower room on an 18/6 on off cycle and have just changed to 12/12 today, i know tomatoes and some strawberries are day neutral but will the switch have any effect? the strawberries are fruiting but the toms are still on their 2nd and 3rd set of true leaves.
I have a veg room but its a bit full at the moment but can make space, i would rather keep them in the flower room as it has the best lighing, temp and space.
Thanks in advance for any replies

Cool I wanted to know this as well. +rep

Yeah as far as i can tell from outside and reading they should respond more to temperature than daylight hours. I'd say they would do better under a 18/6 but my hps are on 12/12 so would rather compromise time for light strength. Hope somebody can shed some experience on the matter

18/6 will get strawberries threw flower and veg in one. i did it once but you need a good 70 degrees and a lot of ventilation.

i'm about 80% sure that veggie plants aren't photoperiod, but they rather by age, not light periods like mj is.. i know when you buy say matters, they will tell you these are 55 days plants, etc, which is how long they take to grow fruit..

a friend of mine lives in florida, and he grows most veggies year round as far as i know...

The flowering response of many plants is controlled by the photoperiod (the length of uninterrupted darkness). Photoperiod response can be divided into three types. Short day plants flower in response to long periods of night darkness. Examples include poinsettias, Christmas cactus, chrysanthemums, and single-crop strawberries. Long day plants flower in response to short periods of night darkness. Examples include onions and spinach. Day neutral plants flower without regard to the length of the night, but typically flower earlier and more profusely under long daylight regimes. Tomatoes and Day neutral strawberries are in this group. Make sure your strawberries are day neutral and you will be fine.

Thanks for the replies
Good info Jimmy thanks, Im sure the strawberries are day neutral they are Chandler mainly and im told i will get more than 1 crop from them. We are coming into spring so im guessing longer hotter days are best and our days are only around 12 hours atm so im sure the flower room will suffice. My main worry is that the sudden switch from 18 to 12 hour days would stress them or stop the fruiting on the strawberries.
