Idea to see plant sex early?

[Rodney007xx]

Hi guys,

Is it possible to go from a 18/6 growth veg cycle in the early stages to just perhaps a few days or so of 12/12 flower cycle to identify a plants sex earlier on?

And then back to 18/6 cycle to reveg?

Cheers,

You could. There are also testing sites like this below where you can take a snip of a leaf from a early vegging plant and send it in.

You will probably need at least 10 days of 12/12 light before you get the gender reveal you are seeking. I am growing some plants now that seemed to take even longer, Cherry Pie, I think.

You can always clone a plant and put the clone under a short-day light regimen. Make sure you tag the clone and the plant you got it from.

Back in the 70-80s used to grow RK skunk we used to cut them back to 12/12 until they showed sex then turn them back to veg it was all gorilla grows so not having an issue with males was a big plus never suffered any ill effects but it added weeks, nowadays I snip clones and immediately put them in 12/12 less stress on plants and they all keep vegging

This year I started putting seedlings outside Mid April. After a coupke weeks they started showing signs of sex (May 1st). I didn’t plan it that way but I was able to weed out all the males.

There are a couple of ways of doing this without testing.

1. Bag a branch for 12 hours a day until that branch begins to show sex.

2. take a clone and root it on 12/12 lighting schedule which should show sex

3. Switch to 12/12 and wait for sex to show and then switch back (possibly causing monster cropping)

4. veg them long enough until they show on their own.

Or you can just wait till there mature and show sex , starts after the sixth node…
