Hi there I’m new to this an currently on my first grow I’ve got 4 girls in a 5x5x6 tent in my garage I’m currently using a 600w light 6 inch exhaust 4 inch intake 16 inch oscillating fan an a little clip fan and a little oil filled rad . I’m on my 3rd/ 4th week of flower an I’m struggling with RH which at the moment is around 70-75% ami right in thinking this needs to be between 40-50% could any help with tips on getting that down please. Thanks
