Crap! Why do the seeds just stop growing after a while? (after germination)

So I am going to keep it very short, so I don't babble on and on:

1) Last growing season I made a hybrid. I collected the seeds
2) This year, I planted 4 of those seeds. 3 germinated, 2 males, one female (female is now chopped up and drying). The one seed that didn't grow, actually germinated, but once I placed it in soil, it "froze" (didn't grow), and rotted.

3) I decided to hybridize again this season, Hybrid #1 X another strain (I have the pollen). I planted 3 seeds (Same hybrids as mentioned in point # 2). One germinated, and I put it in soil. It didn't sprout. So I gently took it out of the soil (with someone's help; this someone has a degree in biology and finished agricultural studies etc, so they knew what they were doing), and we analyzed the seedling. It had a longer root than when I placed it in, and a little leaf was growing.... But it froze. We replanted it in better soil, and shallower (we assumed it was too deep). Nothing.

The other two seeds, after 4-5 days in the petri dish I germinate in (I use layers of gauze with water, instead of paper towels), did nothing. So I threw them into soil, yet still nothing (At one point, last season, this triggered a seed to grow after it did the same in the petri dish).

So my question is: Why the hell are they not growing. I mean, I theorized that since it is a custom hybrid, maybe it is genetically not capable of producing viable offspring. However, I grew 2 males and one female (very nice and THC rich one at that) this year, so it's not the genes.

What gives???!!!

Is there any way to still save these plants and make them sprout?

what kind of soil are you putting them in, it may be to hot for a seedling and your cooking them.

my fresh seed from just over one or two mo. old don't respond well to soaking or paper towel germ. i go straight into jiffy pellets and in three days i have seedlings breaking soil , soaking and paper towel methods benefit older seeds that can absorb and use the extra water

mydixiewrecked: I am putting them in regular potting soil, (the one that I transplanted was put into one of those little starter things - the net that you have to soak with water and it swells into this little cylinder of soil - they always worked well before). They are kept away from heat, at room temperature.

Robert: The seeds are from last year, and they were kept very cool throughout the year, so now they need the moisture. They were older (about 2 years old). (Last gorwing season means, last time I grew lol).

I agree with the hot soil theory

Starting your seeds

^^^^^^ this thread talks about diff methods

Alright, well I did that today with the last seed...knowing my luck, Nature will continue being a bitch and screw this one up too...(seeing as it;'s shell was cracked a bit). I put it directly into moist soil, as recommended by the link above and my friend. We'll see what happens. The other two seeds that I placed into soil before are still doing NOTHING. it's been a week.

This is BS, and I am super depressed because I don't have anymore hybrid seeds to continue my project with. (and I can't make anymore, as I don't have any more seeds of the original parent plants).

I'm not sure man. If you are out there breeding and making your own crosses then I should probably be getting advice from you, haha. It's hard to say what it could be scientifically since it is a relatively small sample size. Try germing more seeds. Personally, I don't like those jiffy pellets for germing seeds. They seem like they work great for a lot of people, but I never had much luck with them.

One thing I do know that just happened to me, is burying it too deep. I germed in the wet paper towel for about a day then planted. I noticed that "lump" in the soil right before it breaks ground. After that, it is usually only a matter of hours before it pokes through. Well after about a day it didn't progress so I removed that top little bit of dirt and noticed it actually shed the shell and sprouted underground. It looked yellow and didn't think it was going to make it, but once it started getting light it greened up for me and is doing well, albeit a little behind the other seedlings.

Yup, I definitely did that at one point; buried them as though I was hiding a corpse. Crap, I think I could have saved my last one if I had that last piece of advice - about uncovering the yellowed leaf and letting it get light. Same happened to mine, but I think it rotted away. I am praying that this next seed I planted today atleast sprouts and is a female. All I need is ONE female. I assume if it is a male, I could put it under stressful conditions and make it a hermie, and try to get a hyrbid that way...but that is really a messy, unprofessional and risky way (as in, you won't know what you get).

If I could just get ONE last female. ONE. I have no more hybrid seeds of my old lot, so let's cross our fingers. I will let you know
