Planting Herb Seeds Is It Okay To Buy Any Kind Of Herb Seeds To Plant?

Is it okay to buy any kind of herb seeds to plant? - planting herb seeds

I want to start a small house plant "garden." I noticed that there are places like the garden stores, bags of grass seed very cheap. Can I trust that the work of the seed? Should I buy one of these "starter kits" or just individually? How big pots I have expected?

Thank you guys!

Thank you!
