if you dont know how to do that? or are unsure of when to do it? you shouldnt do it at all, ghet somenoe you can trust that grows and know what he/she is doing to do it for you, i would jsut stick to ferts and yuor will grow a monster (depending on strain) im sure u will get alot more than a ounce if its outside........its better if the person who is helping you is family
