I've had good luck with worms 707 but now use one called mendo mix from royal gold. They have one called Kings mix that is a lot less dense, but it dries out too fast and is lighter on the nutes. I thought the mendo mix might be too heavy or slow to dry out, but it has been perfect for where I am because it is hot and dry.Hey peeps!!What else can I use for soil on my outdoor autoflower besides organic promix??
