1970 tropical Seeds (asumably not old Seeds) not Sprout HELP!

Well,
i put the half part into purified water and 10% h202 mix. And the other half into just water. 24 Hours long.

Then into damp paper Towel,into opened Ziplock, then into paper Plates under Growlight. Heat map too. 24 Hours Long.

Then the half of Seeds went into pro mix seedling soil, the other stayed in Pape Towel, 48 Hous Long.

So i finally Cracked all seeds, wich i initially Sandpapered at First already.

4 Days from initially starting. No Movement.

--------

Those should be newer reproduced Seeds, not fom 1970, but the Line is from 1970.

Could it be that this is a Line that is just too acclimatized to the Climate? The Seeds looked glossy, not like old Seedstash wich looks pale, im pretty shue cant be thaat old.
So, what to do if they are to acclimatized.? Or if something else, what to doo?


Any Ideas?

Do you know how hold they actually are and what type they are and if the seeds have actually come from their homeland.....if they've been reproduced outside their homeland afew times they should pop without too much issue.....sounds like they may not have been kept in the best conditions...or you just havent given them enough time
Sometimes older sativa seeds can take a couple of weeks to pop....ive seen sativa seeds that have been kept in the fridge for over 10-20 years take quite some time to get going...but they do eventually get going if stored correctly...I would advise to build a small worm bin and throw afew in there...ive seen even the toughest old seeds emerge in worm bins.....good luck

I dont know how often they were reproduced out homeland. It is an old Line from the Tropics.
I guess those are shurely not first Generation, cause they are pretty glossy, not Pale.

I heard only that he grows it every Year, but that tells me nothing if those are an old reproduction, or multiple times reproduced.

Nonacclimatized was my first suspectd. And i try out any method.

Do you think keeping them in Paper Plates under Lights is actually bad?
Some tell to put them into normal Plates (darkness)

Thank you very much for your kind words my friend. That link on the water pollination is interesting. I clicked on it though and only got one post of him pollinating a PCK, I didn't see the rest of the thread. I haven't had much time to research this, but I'm always looking for more knowledge and better methods. Thanks romanoweed for posting that.

I'm happy to share with you what I've found that works for me and some reasoning behind it. Maybe there is something someone can find useful from this
Here is what I do for old seeds:
My method involves washing the seeds to kill any fungus. Damping off is often a problem with old seeds. I soak seeds in tap water and household chlorine bleach (no scent, just plain bleach) for 20 minutes. The ratio is 1 Tablespoon of bleach per gallon of water.
After the soak, I dry the seeds and either crack the seeds or scarify them. I don't have a seed cracker but small hospital hemostats work if you're careful. Usually I scarify them with either fine sandpaper, 2000 grit or an emery board, the kind used for fingernails. Here, I just want to make a pin hole on the side of the seed along the ridge, where the 2 halves of the outer shells meet. You only need a light pass once or twice usually. Don't take too much off. Just break through and make a pinhole in the shell where the 2 halves meet. This allows the liquid to get in as old seeds usually have very hard shells.

Back to sterilization; I use latex gloves when handling the seeds after the 1st soak in bleach solution. Even if I use the paper towel method on new seeds, I use latex gloves, especially when transplanting them into the medium. I had about 20% of my seedlings die off several years ago from transplanting seedlings without gloves from paper towel to medium.
After cracking or scarifying the seeds, I put them in a strainer and rinse them in tap water.
I don't have access to fresh coconut milk, so I use organic, as fresh as I can find. Coconut is a seed, a nut or a fruit. But as a seed, it has pretty much all the goodies for a new plant to live on for a while. It has cytokinins, phytohormones which promote cell division, as well as gibberellic acid, which has been shown to increase old seed germination.
H202 increases the oxygen in the coconut water. Seeds need oxygen for aerobic respiration, breaking down food so the embryo can have energy. I don't know what other reasons for the H202, but I assume that is the primary function. I do know it increases germination rates. I'm guessing, but I would say my ration is about 1/4th teaspoon of 3% H202 to 2 shot glasses of coconut milk. You can add a pinch of finely powdered diastatic malt to add enzymes. On the KG repro, I also added 1 drop of Roots Excellurator Gold.

To be honest, Coconut milk and H202 are probably the most important ingredient. I think they are all important, but those 2 are really good by themselves. As far as time, I go 24 hours minimum and usually go 36 hours, depending on the seeds, my gut feelings, etc.
After the soak, plant the seeds in fresh ewc. I don't use the commercial bagged ewc sold on the shelves. I have my own worm farms just for these occasions. I'll use bagged ewc in soil, but not for sprouting seeds. I plant the seeds in trays or starter cups filled with fresh ewc, with seeds being planted 1/4 to 1/2 inch deep. Don't pack the ewc, keep it loose for oxygen and so the seeds don't get too wet. I put them in my cloning chamber and just mist spray the dome. Keep them warm and humid. I like to keep everything at 80-85F. As long as there is no remaining organic matter in the ewc, they won't mold. Don't let the ewc get dry. Mist spray them if they do. You don't want them too wet, but not dry either just moist. Keep the dome and walls inside the chamber sprayed once or twice.Because we don't want our seeds too wet and have plenty of oxygen, we want the RH to be very high. I put the whole thing on a seed mat and a thermometer inside to monitor temps and RH. RH is usually 85-99%.
Patience. The seeds have been asleep a long time, it takes time to wake up. My KG didn't come up until day 31, then they all started coming up after that. A friend of mine last month had the same thing with old seeds, started coming up on day 31. Give them time and lots of positive vibes.
Peace, God bless

Not sure how seeds from 50 years ago can be “assumably not old”, but you’ll probably have better results if you approach them AS IF they *are* old.
