you can smoke males... you can smoke your socks too..... ahhahah.. but smoking females is the way to go... sorry I couldn't resist the smart ass comment...

your plants look healthy... congrats.... be patient...you will know a male.... the "balls" that smokey is refering to will look like little rose buds... those are very bad.. they have pollen inside them... if that pollen gets out it will fertilize your female plants causing them to produce seeds... yuck

your female plants will have white hairs in pairs of two.... keep looking at the nodes.. they will come!!! you should see them very soon.... 1 day to 2 weeks...

but you will be able to tell..... and make sure you get rid of the males and don't disturb the "balls" you don't want that pollen getting into the air...

good luck : )

oh yeah, you can smoke male but if you are going to put the effort into growing a plant to maturity you will regret it not being a female... 10,000,000,000 times more potent : )
