I have a couple i'd like to try. Nothing rare. A house guest on a road trip stopped at Montecello driving south and sent me tom seeds as a gift that never germinated the usual way.
I just assumed they were a gift shop novelty and possibly old and not stored properly on their end. This was a dozen yrs ago and have been in the dud file.
And why i'm a bit picky where i get my seeds. TGS for years and now from recommendations here only.
My own saved seeds from my prime 'stable' always do well. No surprise that the big box suppliers are a toss-up and low germination as they must be selling older seed. |
As far as oxygen is concerned, a couple of points, the reason I used dilute H2O2 is that it is unstable and easily degrades to water and releases an oxygen atom. I am peeking (a lot) and opening the bag but even so, plastic zippies are not air tight at all and would be permeable enough to not be concerned.
