When should I introduce co2 to my seedlings? Their still pretty young so I would like to know if its okay to try an introduce a little for now to speed up their growth it would it just kill them?

As soon as they start photosynthesis they start using CO2, increasing its level can't hurt.

Unless your growing a nice size crop CO2 wont improve your grow. Air has lots of CO2 in it. grow out your plants w/out co2 & whach em GO....

outside air is approx. 400-450 ppm co2. inside air is a couple hundred more at the very least depending on the room. co2 supplementation will certainly do for yield whether the grow is big or small.supplementation being 1200-1500 ppm co2 in my mind.

Agreed on this, and don't try for anything bigger than 1500 ppm without special plans in place.. with a real good regulator too. Some regulators that aren't built to a decent spec tend to freeze over and that's nowhere near a good situation.
