When can you start using co2 on them?

I was just curious when is the best time to start using co2 on your babies. I am using co2 boost as my source and wondered if it would hinder their growth during the earliest stage of veg. They are only a week and a half old, and just got their second set of leaves. Also, when is the best time to run your co2 and what intervals or amounts do you typically use?

CO2 doesnt wait outdoors for a certain time, dont see why it would hurt at any stage of growth.
Shouldnt do anything but give them a breath of air.

I do not know how much i use, it makes itself inside a jug.
I do know that if I put the lid on the jug for a few sec's it blows the sides out with pressure.

I read on line somewhere that extra co2 during flowering reduced the potency. But that last guy made a GREAT point.They got to breath and if your space is air tight , well. All you can do is try it both ways.

Plants use C02 during all stages of life. The highest Co2 uptake takes place during daylight hours, and in the later growth stages - mainly because there is more plant leaf area to transpire - but it's not going to hinder seedling growth.

I use it from day one. They love it.

Its Co2, its in the air, outdoors, indoors, everywhere. kinda common knowledge id say.
Even fish tank plants need CO2 to thrive.

It is common knowledge that C02 exists yes, but that wasn't the question

The answer to the question is in a simple search, Green Cross.

I wasnt being a smart ass or didnt mean to be,
and yes part of his question was
