Will adding a HPS light stress plant?

Hi,

I have a plant 2 weeks at veg and has almost 5 branches. It is under 4x24W CFL lamps (blue spectrum) and will stay for another 2 weeks in veg.

I am thinking to put it under a 250W HPS light together with all the CFL's and next to an autoflower which is at the same light schedule as the other plant but on late flowering.

Will adding the HPS light stress the plant or is do you suggest me to go for it? Both plants are feminised

Thanks

It will not stress the plant.

More light the better.

and what about the flowering plant? can these affect the veg one?

Yeah after 2-3 weeks you can hit them with the HPS, it's just when they are little seedlings still that they don't need as much light. You should be gtg now. =)

What everyone else said I beg under cfls and flour tubes and flower under 600watt HPS no stress problems.
