Chlorine dissipates after 3 hours in a 5 gallon bucket. Really no need for air stone. I don’t think it’s temp personally. What it is for sure I really can’t say. Bad luck?

top feed start on the edge and work inward.
water usually until run off comes out somtimes fall short but usually my measurments are pretty decent and not off by much its a heavy plant
and hmm that is somthing i have never considered perhaps my switch to regular pots may help abit atleast
might be bad luck… i ditched my non herm clones before they were rooted becuase i decide i was going to run reg seeds from now on and bought a few and got males threw out first sign of balls saw no pistils what so ever. Waiting to afford more reg seeds but running blue dream & pineapple express again as neither hermi’d and praying they dont again
But also trying to learn to use the new DWC cloner i bought on impulse… lol

Make sure to post lots of pics and describe what you are doing.
If there is something that is causing this, somebody is going to pick up on it for you.

True but when it rains it pours. The only suggestions I can make that might (i stress might) have an effect. Are to use a mh bulb during veg, lower the p ratio during veg, let plants get to sexual maturity be4 flower, no superthrive.

sorry forgot my veg lighting is 180w LED and 125wat CFL 6200k ( i think)
i’ve stopped superthrive in general and yes letting plants get larger now thats forsure

With air temps that low in the room while blowing cold air on the roots and with that much water you’ll have issues. I don’t water more than 2-2.5 liters in a 3-5 gallon pot when I have lower night time temps and I always bottom feed in winter. I never water till runoff unless it’s the summer months and even then its rare and I can get steady root temps at night. My watering cycle is plain water one watering and ferts the next. Hope that helps

That’s a good tip there, flipping early can cause hormonal stress leading to intersex flowers.

Could just be some bad luck, but sounds like there is some other factor.
I’d run cuttings of the cultivars that aren’t giving you trouble, until you get it sorted.
Try to keep your environment from reaching extremes (temp, rootzone EC/pH, humidity…)
A photo might expose some clues to some of the more experienced eyes.
Best of Luck

I don’t think so. You can stress a plant over and over and it won’t hermie if it’s not in its code… Light leaks, pH and all of those things are myths.
If a plant hermies it’s because of its make up.
Are you saying that a parent plant under stress produces hermie seeds?

That is my understanding. Stress to the mother plant can produce all male, all female or a mix of normal and hermies, so I have read.

Never heard anything more than rumors on that…same rumors that talk about correlations between environment and sex of seedlings (that now we do know is genetically predetermined).
Any legit source for that claim ?
Edit 1 : I’ve noticed that I came out a bit rude so I wanted to clarify one thing : if yourself noticed something similar, that’s a legit source in my book.

I crossed a Qrazy Train female with a Deep Purple male.
The soil I made myself, and it was poor to be kind. The QT never looked good after flip, but I wanted the cross.
I have had 1 female out of about 15 so far. Could just be bad luck.
One never knows for sure without the resources to devote.
I am trying to remember where I read this. Its been a while. I’ll keep after it.

It is all in the name of learning, let it fly!
In the case of cannabis, there are differing points of view. It is thought that the embryo that contains the seed is not a simple diploid cell, but rather a triploid cell (XXX, XXY, XYY or YYY) or even a tetraploid cell (XXXX, XXXY, XXYY, XYYY or YYYY). This theory is plausible. However, if genetic circumstances alone influenced the likelihood of having a pure female plant that only has female flowers, the chances of this happening would be minimal, and since cases of hermaphroditism are at the very least quite rare, it would appear that the genetic make-up of the seed cannot be the sole factor involved in determining the sex of marijuana plants. It is for this reason that some cannabis growers place more importance on growing conditions, since it has been seen that under poor conditions there is a predominance of male plants. This theory could well be correct, especially if looked at it from the point of view of nature itself: a plant, just like any other life form, has a single purpose – procreation. The observation that under adverse conditions there is a certain tendency for a higher number of males to be produced may, in my opinion, be due to the fact that under adverse conditions it is unlikely that the offspring (descendants) will be able to reproduce successfully. Since a female can produce a certain number of female flowers, which will give rise to an equal or lower number of seeds, the higher the number of females, the more descendants there will be. However, under extreme conditions, wise Mother Nature steps in and increases the number of male specimens, since although there is more pollen if there are, for example, 100,000 female flowers, there will never be more than 100,000 seeds, and thus the population will regulate the gender of the plants’ descendants, avoiding overpopulation under less than optimal conditions.
I think this is where I got it from.

Selfing
Selfing is the ability of a plant to produce seeds without the aid of another plant and refers to hermaphrodite plants that are able to self-pollinate. Hermaphrodite plants have both male and female flowers.This usually means that the hermaphrodite plant is monoecious. Most plants are dioecious and have male and female flowers on separate plants.
Monoecious cannabis strains will always display both sexes regardless of the growing conditions. Under optimal growing conditions a monoecious cannabis strain will still produce both male and female flowers on the same plant. Under optimal growing conditions a dioecious cannabis strain will produce male and female flowers on separate plants.
Stressful growing conditions can cause some dioecious cannabis strains to produce both male and female flowers on the same plant. Manipulating an irregular photoperiod during the flowering stage is an easy way to encourage the dioecious hermaphrodite condition. Not all dioecious cannabis strains can become hermaphrodites. The dioecious cannabis strain must have a preexisting genetic disposition to become hermaphrodite under stressful conditions in order for male and female flowers to appear on the same plant.
If you find a dioecious cannabis strain that has the hermaphrodite condition you can separate this plant from the rest and allow selfing to occur. If the male pollen is viable on this plant then the hermaphrodite will produce seeds. Selfed plants that produce seeds will eventually generate offspring that:
- Are all female
- Are all hermaphrodite
- Produce male, female and hermaphrodite plants because the environment also influences the final sexual expression of the selfed plant
- Express limited variation from the original selfed plant
Breeders should note that it is nearly impossible for a hermaphrodite to create male plants although environment can influence males to appear. Hermaphrodites usually create female-only and hermaphrodite seeds. The female-only seeds often carry the hermaphrodite trait. Selfing has become popular among those who wish to breed all-female or feminized seeds. Unfortunately feminized seeds do very little for the cannabis gene pool as the hermaphrodite condition prevents growers from generating a sinsemilla crop.
Well-informed breeders tend to shy away from producing feminized seeds. Feminized seeds should only be used for bud production and not for breeding. Generating seeds from feminized plants is only advised for personal use and not for distribution.

Cannabis breeders bible by Greg Green:
It is very important to maintain the 12/12 photoperiod with females that have received pollen. If you revert to vegetative growth or disrupt the 12/12 photoperiod it can have an adverse effect on the production of seeds. Also the plant may produce hermaphrodites because of photoperiod related stress and you will only end up with selfed seeds and standard seeds that are indistinguishable from one another. A suspect hermie can render an entire breeding period void and the breeder will have to start that term over again.
It is also worth keeping in mind that even in optimal environmental conditions some sinsemilla branches from certain strains can produce hermaphrodites. Although there may be only one male flower per cola of bud, if the pollen is viable then that branch may produce some seeds. Avoid using these seeds in any breeding program. The pollen may also spread to other branches. This means that there may be a chance that some hermaphrodite pollen has contaminated another branch on the same plant or has traveled to a neighboring plant. Sinsemilla branches are best avoided in breeding environments. If you are going to pollinate your plant try and pollinate the whole plant. The other way to prevent this minor percentage of hermaphrodite seeds is to simply keep a close eye on your females for any signs of male flowers and clip them away as quickly as possible.

i don’t know if you call it bad luck or good luck i’ve been try to hermie some of my plants without success, sometimes when you try to do something it wont work i’ve tried low temps and high temps fluctuation bent defoliate when dont suppose to you name it everything except for chemicals
