ok stop cross venting the air .......u are exposing the plants to outdoor conditions this will effect the plants over all yield
1 indoor air is natural higher then outside air (the co2 we break out is good for plants)
2 the amount of air u are cycling is lower then it really is u still have a massive vault of hot air...... wind shift directions
3 u want to cycle the air in your grow room once every 3 mins minimal this is to get rid of the spent hot air and to cool the plants off (like a breeze) bring them fresh air (not fresh air but air that is unused in the cycle ) ........that is why u see us ask what is the size of your area so we can figure out cubic feet and tell u a matching fan
4 u have no smell control at all /possible pollen in the wind /bug protection .....most of us run negative pressure to control the smell using a carbon filter
5 the way u have it set up if u wanted to add extra Co2 to boost the plant it would be total ineffective just a waste of gas
6 RH u want to keep that Under 60% at 60%or higher mold/fungi spores can attach and grow in the buds wrecking all those buds and ones in wind path (if it has spores on it can kill trash the whole lot) i have some killer weed u smoke it and will give u a infection u need to see doctors about
the point of growing indoor is to mimic the best day possible for the plant as many times as u can in the plants life........the way u got it the plant would have to be thought of as a outdoor plant or a greenhouse/sun porch plant
