Tomatoes on 20/4 produce fruit?

I have some tomatoes growing in my auto tent which is set at 20/4.

will they produce tomatoes or do they need more darkness?

Cheers!

Yes, they will. I harvested cherries on 18/6 years ago, when my ex wife hated on me for growing pot alone in the winter, lol
Under a 600 hps ffs!

I am also curious on photo periods and fruit production for tomatoes, peppers and strawberries.
I have mine under 18 hours of light to hopefully prevent fruit untill im satisfied with veg.
I also haven't given any bloom nutes yet to help prevent it.
I'm wondering how much of a difference I'm making

I have some cayenne and jalapeno plants going in my garage that have been under 24 hours of light since planted and they are putting a lot of flowers on. Was going to put a bed in there but plans changed so I never tried pollinating them but we have such a short sliver of winter that I'll hope to transplant them out before too long.

Pretty sure most vegetables autoflower

Cheers guys! Hopefully they produce some fruit by spring time
