Opening tent

I have security cameras in my tents so i can look in on them 50x a day if i want

I open my tent daily. Multiple times. Entering the tent and breathing gives them C02 which is what they need to breathe. Hence why most people talk or sing to their plants. They breathe what we breathe out and we breathe what they breathe in. Now if your environment is fragile and opening the door makes it go way out of wack then yeah, try to stay out other then checking once or twice a day for a brief moment. In that instance I would add supplemental co2. But if you have a vent open bringing in fresh air from the rest of the home then you'll be fine. Goodluck growmie 🙏

Whenever you need to, they won't freak out.

Once a day when I maintain my plants. Is all I do.
