We have started plants from seeds. Now, they are approx. 4 inchs tall and on the 3rd layers of leaves. We've had them planted now for 3 weeks and they are under flor. 24/7. we are accustom to starting with clones so this proccess of starting from a seed is all new to us.
Now our (my hubby and I) question is when is the best time to sex our babies? Simple as that.....any help would be greatly appreciated

it depends on if your going to scrog or not if you scrog 12" if not wait till its 8-12 wks

i would take 8-12 weeks with a grain of salt. your trees could be over your grow room. personally, the best time I have figured out, actually potroast told me, double the size of your tree and that is what you are going to end up with at the end of flowering. it the tree is a big yielder, figure on tripling the size. an easy rule of thumb there. PEACE!
