Hi, I'm a complete gardening novice, as you can see from my previous posts All I know is I started a tray full of sweet millions inside, in a pretty cold room & only two worked out for me they're developing into great little plants now but it was only two out of about 12, like I say I'm a complete novice just sharing my own experience, I know my friend's dad grew the same kind last year & they were delicious. Good Luck.
