on my first grow latewood ,i used gh 3 part,but used a nutramist fogger .....had super results,no probs,then ,i got a bigger fogger,had to move and now the fogger is too big for the room i have ,due to humidity ...as i get better skills with ebb and flow hopefully i'll see better results.....i'm still looking for a new residence with the right rooms to get the fogger up and running.
