I have heard many different opinions on this. Since I started the caramelicious Plants from seed, I don't know yet which are females. I only care about getting 1, but more would be preferable. My question is, what is the best time to throw the plants into 12/12? I have heard right away, and then as soon as you see the pistols, start on 18/6 again and continue vegging. I have also heard vegg for about a month or two, then throw into 12/12. All my previous grows I have used clones, i've never tried sexing them before, any advice is much appreciated. Thanks

I saw in a video a while back that recommended keeping plant in veg but covering a single lower branch for a few hours while the rest of the plant is still getting light so to force this single branch into flower mode. So keeping plant in veg mode but taking one branch and putting it into a 12/12. It was recommended to use a loose paper bag or something similar so as not to choke the plant and it will take some time doing this daily before you will be able to determine the sex, but it's better than waiting until flowering and realizing you have a bunch of males or hermies and it decreases risk of pollination to any of the females. I have never tried this yet myself (still in early veg of 1st grow) but I'll be giving it a shot once my babies get a little bigger. The guy who made the video said it allows you to determine what sex your plants are earlier without having to wait until they are in full flowering so you can get males out before they have a chance to pollinate any of the females and ruin your crop.
Good luck and hope this helped.

Thanks man, Yeah i never really tried it before either but we'll see what happens. Thanks for the advice dude.

What height you veg to is determined by your actual growing height and your light capabilities.
　
Start with your height, if you have an 8’ ceiling you start off with eight feet. Then you subtract the amount of distance from the floor to the top of your growing medium. Let’s say that is 1’ so now that means you have 7’ of height left. Then you measure the distance from the ceiling to the lowest part of your lighting when it is fully raised. Again let’s say that is 1’ so you subtract it. Ok, now you have 6’ of height to grow in. Now you subtract the minimum amount of distance you need to keep between the top of your plants and your lighting so you do not have heat issues. Just for the heck of it once again let’s say that is 1’. Now you have 5’ of growing height left and that is your usable amount of growing height.
　
Now look at your lighting. Can it provide adequate lighting down to the bottom of your plants if you use all your usable growing height? If not how much of your usable growing height can you provide adequate lighting for and then that is your usable growing height.
　
Once you know the maximum height you can deal with efficiently and effectively then you use the double to triple in flower thing to figure out at what height you need to put your plants into flower to remain in your usable growing height limitation. (That is of course if there are any.)

Sometimes they preflower when they reach maturity while in veg cycle. You don't need to stick a bag over the lower branch.... females sprout a few pistils, but they won't actually bud until you flip the light cycle. My last stuff preflowered in 4.5 weeks.

If you're growing from the same seed stock, the males will tend to take on certain traits and so will the females...potentially. It's really easy to sex them once you get the hang of it.

I've never tried it .. not sure if it will work ...

plants show definite signs of sex shortly after they reach alternating node stage .. after two or three alternating nodes .. I put em under HPS light for about 10 hrs on 14 off till they show definite signs of sex ... i.e. female hairs or flower sacks ... then back to long light hours .. 14 to 18 under HID or flourescents ... I don't seem to lose much growth they show signs in first two or three days but Id let em go five or six .. so there is no doubt .. the males first show what kinda' looks like a hair at first after five days .. u should know for sure

it will show its sex with out flowering about 4 weeks after germinating. look for the very small preflowers at the 4th or 5th node, or on some of the larger lower branches.

When you put them on a 12/12 and a week later some of them have big things that look like nuts hanging of them, you've got a male bro, lol.

I have some AK-47(serious seeds) seedlings close to a month in veg. I topped them yesterday and plan to veg them for another two or three weeks. My plan is to bud them out and compare the smoke, node spacing, leaf/bud ratio, height and other various traits and find the best strain for a mother plant. Before putting them under 12/12 lighting, i will take clones from each plant that will be used as mother plants later on. I hope this helps you some!
