"...but my yearly harvest is still better because of it I believe".
Im sure it's better. More space is always more space. That is the number one factor when you aim for bigger yields. You can only have that many buds in m2.
Density is the only factor I can use to increase yields really...
I see people managing to get 1 oz per cola all over on here.
I wish I could have 4 colas per square foot and manage that!
Don't see what else I can change to increase that. It's not like I'm a new grower either.
