For germination to be a success you need water and warmth only. You do not need carbon dioxide. It is a common misconception. As seeds do not have leaves for photosynthesis, they do not need carbon dioxide.

A seed needs water, oxygen, and the right temperature to germinate. Water helps activate the enzymes necessary for growth, oxygen supports respiration, and appropriate temperature triggers metabolic processes.
