Weed luvs fast drainage. Mine is 45% drainage. I use perlite and expanded clay balls. In the cloth bags I have to water every 48hrs. I give each girl around a gallon ea time (7 gal bags).
@Garysmells21 your girls will go to the finish. Pick the dead leaves off and let them go. I had a lot of experience with organic growing and still had a 2 or 3 year learning curve growing weed. I feel like I still have things to learn about it. This is a great place to gather knowledge.
