24/7 to 18/6 question

I have 2 400 watt lamps in my veg room located in a shed. My problem is that, do too cold temperatures, I switched my lamps from 18/6 too 24/7 to help maintain 70 deg. + temperatures.

If I want to switch back to 18/6 am I going to stress the plants, or accidentally induce flowering?

I thought about introducing the dark slowly over a week or two to do this, but I thought that I had better see if anybody else has done this befor and what results or problemds they encountered.

Thanks in advance for any help on this

Flowering won't happen until the plants recognize a constant pattern of 12/12. You should be able to go back to 18/6 with no problems.

That was my assumption, however like I said, I thought I would check with those that have gone on befor me.

thanks
