Pre-made soil, perlite, worm manure, etc worth buying?

hi,

well looking to start my second grow.

starting to buy all the things i will needs. got seeds, pots etc ready

i was just looking around ebay for perlite and i found this soil

i have dealt with this company before and they were good.

from my limited knowledge that seems quite good. contains everything i need (i think).

what do you reckon?

i think bio-mix do a organic alternative thats better. id go with the organic one. peace.
