Hey star how you doing?

Plastic is fine I use it. You do need to drill a shit load of holes in the bottom and part way up the side from the bottom. Drainage is very important you don't want the water to sit in the dirt then you get your problems.

Terra Cotta is great but it never comes with enough holes and they are never in the right place. That's my problem with Terra Cotta just not enough holes for drainage.

50/50 Perlite mix is just about right for a quick drainage. Yes you water more often but that's not a bad thing if you have proper drainage.
