I read you can tell while they are in veg. And they will pollinate your whole grow while in veg. Sent from my iPhone using Grasscity Forum
Idk know where you read that, but absolutely not true. When you change the light cycle to 12/12 within the first week or so is when you'll start seeing the pre-signs of sex, this when you spot a male and pull it, its not gonan pollinate unless you catch it way late, you will be able to tell, I'm sure you've looked at pictures and if you haven't you should.
They'll show sex in veg at about 8 weeks of age. You can google "sexing MJ plants" for some really clear drawings of what you'll be looking for at that time. TWW
Absolutely will know sex before inducing flower. Just wanted to clear that up Sent from my SM-J320P using Grasscity Forum mobile app
Well that's news to me, guess I better take a look cause I was about to flip them next week. Sorry about the misleading information, thanks for setting it straight.
Some of us do not have the luxury of time to determine the sex in veg. I know I don't. So shortening the photoperiod is how it goes down over here when we crack seeds. Out mother plants are quite old and all show pistils.
And that's probably why I never came across that information here, because most journals and articles I read, people are flipping at 4-5 weeks and I'm looking all over my plant when it was at that stage, and I'm like wtf what are these lol. Makes since though keep it in veg long enough and it will show. Actually after reading this this morning, I went to check cause mine are close to 8 weeks, and sure enough my 2 biggest bagseeds plants are female! Flipping for sure on Monday.
Imo it varies strain by strain how long the plant takes to display sexual maturity, some show small female-pre flowers at 4/5weeks from seed/veg others need a couple extra weeks maybe a little more, u less your growing from clones off a mother plant, you will always get lots of different variation from seed to seed, even if they are of the same strain., buy Jorge Cervantes medical indoor bible, or Greg greens'the cannabis grow bible' and there's is stacks of detailed info in there on pre-flowering and even diagrams to show you how to sex your plants early thought taking small cuttings and so forth., along with that patients is a virtue, she/he will show when it's time so sit back and enjoy this beautiful plant thrive and grow! Happy growing.
