I've read a few conflicting ideas about this on forums and in books. Some say soil particle size should be in proportion to the size of your container, while others say they should be inversely proportional; and many either suggest maintaining the same particle size regardless of pot size or fail to mention any connection between the two.
This might not be an issue for many, but since I have material for a few
meme (under 6"), a few
chiu (12" to 24"), and thinking about building a large grow box, it's got me scrathing my head. Also, it seems kind of wasteful to toss out everything that sifts smaller than 1/8" and larger than 1/4" if there are some situations where I could use those materials to the tree's advantage.
I'm not looking for hand-and-fast rules here, just some ballpark idea of how small or large my container can get before I should start considering using larger or smaller particles.
Also, where would you suggest the extreme cut-off point would be for maximum or minimum particle sizes regardless of how huge or tiny my containers are?
