From what I have researched plants breath more co2 according to the intensity of light. If your not running your gavitas to full capacity it sounds like they'll get what they need. My experience with co2 has shown me how benifical running it at full capacity is. For instance my rooms air tight. week1,2,4 and 6 they use about 1/4 of a 50 pound bottle. Weeks 3,5 and 7 they use extremely large amounts. On average in one harvest I'll use 2-2.5 fifty pound bottles. It's amazing to see the growth spurts those odd numbered weeks. I've recently started co2 in my veg room curious to see long term results
