i have a magnifying glass but its still kind of difficult...idk they all look like females right now but the pistils are really small still so i cant really be sure...how long can male and female stay together before it is a problem?
If it's still hard to tell whether the plants are male or female, then you are probably safe.
Doesn't sound like you're quite there yet.
But AS SOON AS YOU REALIZE the sexes of your plants, get them as far away from each other as possible.
They can start pollinating as soon as the male and female parts are visible. And that's no good for you and your grow plans.
It's good to know these things. So many newbies mess this part up, right before their grows eve get started...
good luck!
