F-13 hermaphrodite issue and questions

(I apologize if this thread is double posted - I had troubles the first time I tried to submit it)

Any thougths or suggestions on the following issue would be greatly appreciated!

I started 10 seeds of DJ Short's F-13 about two and a half months ago. I let them grow for 2 months (20 hours/day light schedule) before taking clones. At about ~3 weeks into the grow, I had a malfunction in my grow room - the timer for the ventilation fan failed and the room temperature jumped to about 106 degrees for a few hours. I fixed the problem, and the plants seemed fine... Ok, fast forward a few weeks and I noticed some of the plants were flowering. Or at least I think they were. This is my first grow ever so I wasn't quite sure. Are these real flowers? pre-flowers? calyxs?... I wasn't sure. They looked male, they looked female. Very confusing.

Anyhoo, I kept the schedule at 20 hours/day and I figured that should keep them from going into full-on flower mode, right? At about 2 months, I realized/accepted that several of my plants are hermaphrodites and yes, they were flowering. One of them was so far gone I just pulled the cord on it - the flowers were still small (less than an inch height) but I noticed that a bunch of the male flower sacs had opened and released pollen. Ack! Two others didn't seem so far along (there were clearly both male and female flowers present, but they were very small) so I took cuttings from them when I took cuttings from all the other plants to make clones. I then killed those two plants. The hermaphrodite elements on a fourth plant wasn't so obvious and I missed it, but last night I saw it had produced seeds!?!. I mean, it is definitely a hermaphrodite, the flowers are quite small, but attached to these very small flowers I noticed seedpod-like things, several of which had cracked open revealing one or two normal-sized seeds nestled inside... None of the books/articles/posts I've read mention anything about this sort of thing. I killed the plant (sigh) but saved portions of the branches with these seedpods, thinking that maybe the seeds can capture what is left of the nutrients in the attached branch and leaves and maybe become viable for future planting.

Ok, that is the background to my questions.

1. Why didn’t keeping the plants on 20 hour/day light schedule prevent the hermaphrodites from flowering? What’s up with that? These were not autoflower seeds.

2. Will cuttings taken from hermaphrodites (which I believe became hermaphrodites because of stress, not genetics) continue to be hermaphrodites as clones, or will they revert back to their original sex in future grows? I mean, is it worth even saving the clones I took from the 3 hermaphrodites for future grows, or should I just say last rites and let them go? All the cuttings I’ve taken from all the plants have survived (yippee! beginner’s luck I’m sure).

3. I think I understand how feminized seeds are created… does the same hold for seeds produced on hermaphrodites that were once males? Can male plants even become hermaphrodites? Could the seeds I saved (assuming they are viable) be ‘masculinized’ if the plant was male before it became a hermaphrodite?

4. And finally, how likely is it that the pollen released by the flowering hermaphrodite will affect the remaining female plants that were not hermaphrodites and are just now beginning to flower ( I switched to 12/12 about a week ago). I think the pollen was released about 4-5 weeks ago, when the non-hermaphrodite plants were still very much in a vegetative growth stage. My grow room is in my basement and is small/airtight – 9’ X 10’ with a low ceiling ~7' height. The ventilation is fairly good – temperature with the one exception described above has never been a problem even when it was 90+ degrees outside.

Thanks for any insights!

Really 106 for a few hours shouldn't have had that dramatic of an effect on them. I did way more mean things on my first grow which started outside then went inside to floros and cfl's. Oh and we also reversed night and day when they came inside. Oh and we also over fertilized the shit outa them. 2 outa 3 grew some nanners and we ended up with a small amount of seeds. These are what we are growing this year and they all female, so far anyway lol.

Are sure there isn't something else going on, ie: light leak

Good luck and keep updating, the whole hermy thing is a popular discussion these days

1. maybe you got the wrong seeds. Are you sure they were herms and not just males. Males start earlier.
2. if the strain is this sensitive do you really want to keep growing it anyway's lol
3 from what i've read, although rare yes males can become hermy's and grow flowers
4. My guess is there's a good chance some of the girls got pollinated, nature doesn't try to make to difficult, there could be pollen on the leaves that will fall onto the bud sites.

I am prolly not much help lol, but i find your story quite interesting.

So i just did a little googling and dj short f13 are just regular seeds that mention a sensitivity to nutes. Again i think you just had males show up in your grow room but without pics we will never no for sure lol. Also IMO the prices for them are very high.

Thanks for your responses! I wouldn't be surprised if I mis-diagnosed the situation... this is my first grow after all. However, why I think it was a stress related response was that the plants produced flowers while they were on a 20 hour per day light schedule. The seeds I saved from the one plant look 'ripe' (i.e. hard shiny coats) though I just flipped to 12/12 a week ago. I spent long time looking at the flowers on the plants, comparing them to photos in two books I have and some of the flowers looked very male-like, and some looked very female-like, both on the same plant - sometimes on different branches, sometimes right next to each other. But like I said, it was very confusing because this is my first time sexing cannabis, so it was all new to me.

I've also read that F-13 is very sensitive to heat stress, and a common response is going hermaphrodite. One person remarked on a thread somewhere that F-13 can be a "tricky girl"... probably not the best strain to attempt on a first grow. But live and learn. As to nutes... I've been very light on nutrients. Only organic (all biobizz) from a third to half recommended concentration when I feed them. About half the time I just water them. So far the plants have been very healthy - no signs of disease, bugs, anything, ncie dark green leaves, lots of nodes, bushy, etc. Everything has been great, except for the hermy thing of course). Given the limited height available in my grow room, if anything I've been trying to slow them down and train them to not be so tall. Now that I've removed half of them from the grow room (one of the plants turned out to be male, so along with the 4 hermys, I've removed 5 of the 10 plants) I have more room to train them into shrub shape. One of the remaining plants is definitely female - I'm still not sure on the other 4.

And yes, F-13 are pretty spendy. I went with DJ Short because of a strong recommendation from a friend who said you just can't go wrong with DJ Short gear. My expectation is/was that I have good chance of getting a real keeper mother plant with F-13 seeds and given my limited space, I don't have a lot of room to experiment.
