I need advice.
I was following the protocol of Rich Howard regarding cold damp stratification of seeds. I made one change that I do not think will matter, but now not too sure. I used perlite rather than vermiculite as a medium for the seeds to sit on while they wait in the damp sealed zip-lock baggie in the fridge. Every time I check, the baggies still have plenty condensation in each one, and a tiny bit of residual liquid in the bag corner.
It has been 5 weeks. Am I supposed to see anything at this stage, or do I take them out of the fridge to room temperature, which is when they are to actually germinate? Right now, they just look like seeds in a bag. Same as the day they went in.
I skipped any damp stratification last year and most of my seeds germinated fine, regardless. But people are touting >95% germination using this damp method so I figured I should give this a proper go, this time around (as the seeds are more expensive ones this time around I want maximum germination).
Should I pull them out the fridge or wait longer for something to actually happen in the fridge? I am going to wait 1 more week for the 6-week period, but unless they all magically pop open within the next week I would consider that I have done something terribly wrong (FYI, they germinated fine in wet perlite last year at room temperature, after cold-dry storage). Or maybe my fridge is broken and not as cold as I thought.
Help.
This is the advice I am following:

What do other people do?


Edited to add that I just read a similar recent thread (link below) but it did not answer my question about what to do if they do not germinate after 6 weeks.

They are not supposed to germinate in the fridge, they germinate at room temperature after coming out of the fridge.

Thanks! Thank You!
I think the page of Rich Howard confused me, as it compared ones that had been left in the fridge for 2 months (and those were huge) relative to ones at 4-5weeks (with just a little poking out of the seeds). That seemed to imply they were germinating in the fridge, and not waiting until they come out.
I will stick to my plan then, and pull them out after 6-weeks. I was just worried if that was the wrong thing to do the seeds may 'reset' at room temperature and I would have to do it all over again. D'Oh!

I can see how it could read like that, but if you read the DJ article in Rich's link at the bottom it should be clearer.

Good answer from Sooby Thumbs up

As to your other concern, I have used perlite rather than vermiculite, so that is not a problem. Good luck and please keep us posted as to how it goes!

I also use perlite, mostly because that's what I tried first, so I have a big bag of it. I usually refridgerate for 5 weeks, and plant all the seeds at once. My experience is that close to 90% of the seeds that will germinate will poke their heads up in 5-15 days. You'll see stragglers, but I always thought it was kind of amazing how many started in that 10 day span after stratification.

What media do you use with the Rootmaker 32 cell tray? I've been using peat pots and pro mix but I'm tired of buying new ones every year. It looks like the Rootmaker pots can be used year after year. Is that correct?

I read that too, Bob. The Rootmakers do look cool.
Never had much success with peat pots. They always grow mushrooms out the side, and white furry fungus up the walls. Not great if you are trying to prevent damping off. I always had to drown them in fungicides. Sighing!
