Well, about 8 years I was tired of the great stories I was hearing about CO2
when I was having great luck with plants without it so I experimented.

I set up two identical 30 gallon tanks with the exception that one had a yeast
CO2 bottle hooked up to it.  The results astonished me when in the CO2 tank
the Amazon Sword I planted at 9" had outgrown the tank in under 5 months. 
The other tank had the Sword plant barely reaching the water surface.

Since than I have used it intermittently and just recently switched to a
home made system.  I must attest that it does make a difference with every
plant I tried so far.  The only caution point I found was with Crypts that
out than sprang back to life months later stronger than ever.

Getting back to your original question.  Yes, you can have plants without it
but it makes them look so much better and faster growing.
