OK so, Ive had the misfortune of having more than a couple males. This morning I had to cut down probably my biggest plant because of it ::sigh::. This is the time of season plants will show their sex ( males usually do weeks before now but). Here are some males preflowers and what to look for...They grow little pollen sacks that look like balls, they grow in clusters. I do have some females that are big though. Here are some female preflowers, females grow little white hairs called pistils. [/ATTACH][/ATTACH] Hope this helps for anyone who is unsure, and I hope you do NOT see any signs of males. Good Luck!
