soil Moving to Red Solo cups, what soil to use?

[CBarkley]

I'll have to agree with Jamison. I usually mix mine a little heavier on perlite. Either way, that combination works well.

Dj, keep it simple....Out in the untamed wilderness, they get dirt, sun and rain and they do just fine.

You can also develop algae in your cups with clear cups. I originally used clear and wouldn't recommend it.

For the sake of ease of checking the roots, and yet blocking light to them, you could always doublecup. Clear inner cup and opaque (walmart at least sells black solo cups) outer cups. Not as environmentally friendly, but you could always reuse them next year.
