yes, upgrade this defence lab first then you can upgrade all of your turrets to next lvl which can improve the damage and the range of your turrets. Defence lab deal with damage and range of your turrets. The other one deal with stronger ( harder to shoot down ) is platform, upgrade your platform to make your turrets harder to destroy.
