Sexing regs without flipping to 12/12

[Tuned]

The pics above this post are perfect examples. You dont need to flip to determine sex, keep seedling growing as fast and healthy as you can and somewhere between 4th and 10th node they will show. A magnifying glass will help.

I want to top once the plant hits 5th node for training purposes. I think topping slows down the original plants ability to show sex.
If I wait for the plant to show and don't top, I miss my opportunity to train.
I should have enough of a cutting from topping that I can flip.

Sex is almost always appearing at the 6th node and takes about 6 weeks from seed to show. Males show a little before females.

I've grown a handful of photoperiod regs and have never had an issue determining sex in veg. You just have to let the plant grow and eventually you will be able to see preflowers and then eventually you'll see some pistils on the females but I find it pretty easy to tell before that. Usually between day 30-40 from seed

I can always tell by the time they're a month old. Just look for the onion or the lobster claw.

Wha do you mean by this? I’ve got a couple regs going that are a month old. What is an onion, or lobster claw? I want to look for them.

Idk about lobster claws or onions...but when the plant is giving you the middle finger, you got urself a male...arrogant little cuss they are, the lot of them.

This plant has been under 18/6 lighting since the seeds popped.

Those are pollen sacs.. and by now they have impregnated any females in the area. You ain't seen seeds yet.. but you soon will if there's any ladies in the house.

Just illustrating to the op that sex can be determined without flip.

Shewwwweeee. Color me pink? Is that what the saying is?

i never run regs because of the way I thought I had to sex. Doesn’t seem half as iffy now. Thanks !!

Growing until the sex shows isn't always practical it depends on your goal, if youre happy to be left with x amount it's not a problem but if you want to fill your tent with clones/plants then revealing the sex is the way to go.

they call it 'Monster Cropping'!!! but it may be a hoax ... but revegged plants show some heavy growth and super large leaves for some time but still the transition time from flower back to veg may offset the gain...

I posted a bit on this a few days ago.

Monster clone V Regular clone time difference

The smaller plant was cut/cloned after sexing plants on January 8th It's a long way to go re vegging. The bigger plant was cut/cloned from same plant only the plant was allowed to re veg first before cloning it again, that was on 27th of January. Today the smaller plant is 48 days old...

I can usually rework my canopy to make up for the pulled males, but sometimes there will be a cluster of them and the space never gets completely filled.

Here's a pic of a clone taken and put into 12-12.
When I've that option I've no need to veg plants unnecessarily.
