Make sure the lava rock is the red / rusty kind. The black rock is absent iron and some other shit I don't remember.

Also, its GREAT to take some rock and bash it with a hammer in a pillow case. It creats a lot of dust and that dust is wonderful mixed into the soil

Makes BIG BUDS in my opinion

Soak the red rock in proper water overnight before you use it for the first time....it penetrates millions of pores and won't dry out your grow from the first water.
Bummer, only black lava from the Big Island. Red it will be. I have five weeks to get my shit together.
