Don't waste the money on mylar. Spend it on better lighting, airflow, or nutrients. Mylar is simply a grow industry gimmick. It is something completly un-neseccary that they want you to think will boost light output by a lot.

Plus it's a pain in the ass trying to size it and stick it up and keep it completly flat.
