1 for every plant you intend on growing, but remember that every seed might not germinate so a few extra seeds might be reasonable to have.
You should also grow about twice as many plants as you want. There's a 50/50 chance that the plant won't turn out to be female.
NAMASTE whats been posted is true for is great for the most part.What stain your going with ways the most to me.Some strains yeilds are high wile other are smaller.How much space you have and were and how you plan on doing this all plays a part.
Less of a hassle though. You dont have to worry about ripping plants out etc. Your basicly paying the same price, 10 seeds non feminized, 100 bucks, 10 seeds feminized, 200 bucks. Usually a little less. You have a 50/50 chance of getting a male so basicly 5 are male. So basicly your paying 100 bucks for 5 female seeds or you could pay 200 for 10 female seeds. You usually see them for around 160 though. Depends on the straibn i guess.
who would pay 10 bucks a seed for non-feminized seeds? if you look around, you can find just about every strain for under $100...not all, but just about...
Exactly not all, alot of the more known strains cost over 100 dollars easy for 10 seeds. Most smaller plants cost more too which most indoor growers want. Dont flame me if im wrong but arent a lot of the cheaper strains rip off's of say the true northern lights, white widdow, etc?
