Best vs Fastest way to determine Sex for rookie pheno hunter

[Nugteq]

Yup. Lets hash it out. What is better for plants to determine sex? What is fastest for farmer to determine sex?

I know a lot of us want to fine tune our perpetual grows. SO with that in mind. Time is always an issue.

And I'm very inexperienced with growing. So whats all your opinions on the BEST VS FASTEST way to determine plants sex?

Have quite a few strains going and quite a few seedlings that are taking up too much time and space.

You know we all hunting for those sexy thick females.

I've only cloned the tops, started 12/12 24 hours after placing in rapid rooter to determine sex fast. What do you all do??

 

[chemphlegm]

I plant them, regular or fems in the same room. I keep the regulars together in the flower room until they show sex. I genrally kill males, but never in front of the girls of course.
If I want the newly sexed ones to veg more I return the fems to the veg room. theres no tricks till we get a dip n tell dna swiper

 

[Kingrow1]

Just use fem seeds or clones

 

[Nugteq]

Ok. So no ez tricks thanks chemphlegm. Anyone got any feedback for breeding great moms from regular seeds? Reveg or clone?

Am I understanding you correctly? You've taken cuttings and went to 12/12? Or are you flipping plants right after topping? Either way is wrong.
Want fastest skip 12/12 go straight to 11/13 or 10/14 even. Males will show first.

If you want to make an educated selection in which female in a group to keep and work with it will take at least 3 grow cycles. Bottom line you have to properly cure the first grow to get the final result.

Nothing easy, kinda is what it is. Finding a great mom is simply just keeping clones of your favourite plants and eat sleep grow repeat.

Eventually you can get more technical but keep it simple and you shouldnt go wrong

This company will test your plants for you. They send you a small kit about the Size of a birthday card, maybe a little bigger. 10 test are available, you dont have to use all 10. You basically rub an imprint of the leaf on the paper they provide and they test if it is a male or female plant two weeks from seed sprout.

Seems like this is your first grow. I just suggested a kit below that will tell you the sex of the plants. Take your time and don"t think you have to speed ball through things. Personally I would have waited the two short months it usually takes for a plant to reveal it's sex. From that mature plant I would take clones and veg.those and flower them.

Seedlings dont take up, that much space just depends on the size pot you started them in.

I grow them until they have about 7 nodes then top above the 4th node and put the tops under 12/12 light right away to get them to throw flowers. I've waited way to long to find out looking for pre-flowers to come out on their own,

Once I know who's who I repot the girls and toss the males saving me the time, space and expense of growing plants I don't want in big pots only to have to chuck them out when they flower.

How long does preflowers take for you? It should only be six weeks, maybe even seven before the plant starts to show sex, under 16/8 hrs of light. I have even used 20/4 hrs of light.

I did my last pheno hunt a little differently. I had 25 seedlings in solo cups and transfered them to 5x5 gallon promix. Thats right 5 plants per pot unsexed. Switched to 12/12 and cut off males at ground level as soon as they show. Lucked out and ended with 19 fems. I took clones of the three i like the best at flip+21. I will post some pics when they fix website

I mean that works too!

You have to grow them all out to know what would have produced the best. What did you do with the other 16 plants?

Never found the need for cutting or even moving into flower to determine sex. Right now I'm at 45 days since the regular beans hit the water and I've confirmed 4 ladies, 2 undetermined, one male. Imho it's been all about keeping a consistent environment and proper feeding to steer towards females as the undetermineds are looking that they will be ladies. Use my digital microscope, never failed me yet. Girl on top, boy on bottom. Some take a few days longer in veg to show their sex. According to some folks some strains have to be flowered before sex can be determined, personally I've never run into that issue... First 4 weeks 18/6 66-70 F in the dark, 72-75 with the 6500K cfl's on in my nursery. Also keep the humidity on the higher side, I just gave them a daily misting. Now under 400 MH going to 1000 MH tomorrow. And as is stated in numerous places, for feeding less P&K more N in the first few weeks and I'm a happy gardner.

those look good. thats how we all do it, but sometimes we dont have time to wait to see these sex indicators. Many dont wait for preflowers to make the switch either. sometimes I do sometimes I dont. I'll say this though...when I do see preflowers before switching schedule....I am rewarded greatly in the next 70 or so days compared to those that did not, a bigger yield every time.

Yes, the yield and plant vigor are well worth the extra wait. That and the fact that as they mature I can assess which plants are 'jewels'. Usually at about the 4th week of flower I'll cut my clones for the next run. The system has never failed me. The extra tme it takes for the clones to revert back to veg gives more than enough time for harvest and clean-up and any room mods that need be addressed.

I've only taken cuts in flower one time, because it was a bitch to get them to root. I think it was closer to the 6th week though.
Do you ever experience this or have issues with lack of vigor?
This would work great for me because I like to do a light defoliation and lolipopping at week 4

Some incorrect info here. You can push for male/female/hemaphrodite without the stress of imposing bloom, then "reveg". Females, weak males, and those with hemaphrodite tendencies will reveal themselves quickly. Strong males, those desirable for breeding, will hold out far longer.

How, I won't share. For every "1" genuine grower here, there is 1,000 deuchebags that could capitalize.

Edit: "twnedwncies", what the fuck?!

I made a little aero cloner and it works sweet. Can't recall it taking more than two week for root nubs to show, guaranteed by four weeks all would have well developed secondary roots and the beginning of the branch roots. I've never had any issues with loss of vigor nor hermaphroditic tendencies. Although as with any plant it has a natural tendency to move towards hermaphrodism if the plant remains flowering but not fertilized. They're programmed that way for survival. I believe that as the cuttings are taken at 4 weeks at the maximum, the plant has not been in flower long enough to trigger the hermaphrodism. I have had nanners show up, but only after week 8 in flower, and that tendency is also I believe strain dependent as to when it will develop. I've heard Thai strains and Blueberry can be a handful in regards to these issues. Don't know from personal experience with those strains though. It may take some time to find the right plant though, but once I do I'll just start a couple mothers now that I have the space for them. Before I didn't have the space for a mother and taking the cuttings at the flip left the developed roots way too long, all the plants roots would be tangled in the aero cloner. Felt it was more stressful to the clones having the roots breaking up while attempting to untangle them than to just take the cuttings in flower. Just starting off my grow again. Took 1 1/2 years off as I'd moved and have spent the time and money in my new place to create the closest to perfect grow rooms I could.
