Hey dudes! I'm currently 14 days from seed and had been running my veg tent without an exhaust going. I only had the intakes at the bottom open(passive) with a filter over the bottom holes on each side. Both holes are 12 inches with filters over them. What I'm wondering is could that have caused too little c02 in the tent, possibly causing issues? Not sure how well air could come in and out through the filters without an exhaust going. I've got the exhaust hooked up now and the plants deff seem to like the fresh air coming in. I was thinking since they were so small I was going to set up the exhaust next week but then was thinking maybe it was causing low c02, possibly causing the lighter geen color i was seeing. Either way the exhaust is hooked up and ducting the stale air out of the top of the tent. My main concern is if they were affected by low c02 as seedlings could it affect them later in flowering? Or since I fixed the issues, i shouldn't worry about it? Thanks dudes

You have a light leak. If you see light coming out you'll have light leaking in

Will light leaks be a problem for my veg tent? I keep the room in total darkness when I’m not in it. So the only chance light leaks IN is when I’m in the room watering them which means the light in the tent is already on. Light leaking out I’m not worried about. I have a different tent for flowering that uses a forced air intake that doesn’t let light in or out since there is no passive intakes like shown above on my veg tent. Really appreciate the feedback :)
