Hey everbody!
Since I like to use large drainage holes on my soil grows, I was wondering what I could use to stop the soil from pouring through.

I'm currently using GK's method and put a sheet of newspaper down first, then an inch or two of pearlite followed by my soil mix.

However, I'm afraid that this is stopping too much of the water from pouring through the bottom..

What else can I use?

Obviously something that won't rust, get moldy, attract insects, ect.

Help! :dance:
