I use it in soil. Not at full strength. I read that xcrispi uses the Latewood recipe at 1/2 strength for soil. That is what I will be using this go round. As for additives, I use liquid karma every 2nd or 3rd feeding and topmax only during 12/12, along with unsulphered molasses. I also use hydroguard and hygrozyme occasionally to keep the roots healthy, not at the same time though.
Good luck:thumbsup:
