Whether 5 seeds are worth 200 bucks is certainly a matter of opinion.
My opinion is that if it is your first time growing, you should NOT buy the expensive seeds. Nirvana Standard seeds are lik $20 for 10 beans, and bag seeds are like, $5-$20 a gram lol! Practice on bag seed to see if you can successfully germinate them and grow seedlings to 5 healthy nodes before you drop way too much $$$ on seeds.
If you ask me, yes, that is too expensive, unless it is a strain you are just DESPERATE to have in your garden, and you know for a fact that you can get EVERY ONE of them to survive.
