OK, well i use the line of foxfarms, foxfarms big bloom and big grow from seedlings till harvest in addition to beastie bloomz. The soil also helps a great deal if u use soil my faviort is foxfarms ocean organic, it has sea kelp, bat guana, and many other micro nutrients that you well need. Its like giving steriods a skinny neard. It will take off and grow more fuller and over all harvast will be insane take a look at my pics. also co2 will help a great deal they now have what is called co2 in a bag i use two of them and it is cheaper than a co2 bottle and works the same ive already tested both ways
