What temperature is your dry room? I understand that the goal RH will change based on temp. If the room is 15C our goal RH will be 15-20%, if it is room temp (20C?) our goal will be closer to 25-35%, as per CPC recommendations. What is the preferred temp for a dry room? Thanks!

Does anyone have recommendations on an economical balance that has a 0.1 µg resolution? What are you using for dust seed or spore? Thanks!

We had a potential project with salvaging Rotala ramosior (annual) pop up and we are hoping to quickly find information on this plant so we can advise/store properly. Has anyone worked with this species (or genus) before? A wetland annual plant, we are hoping to know about when best to collect, how best to prep and store, both long- and short-term, and how to best maximize germination. Any experiences working with this species would be most welcome.

Hi, all.  We are going to be doing tetrazolium testing for viability with Apios priceana and Physaria globosa in the near future. However, I am finding it difficult to acquire full procedures for tetrazolium tests that are genera or family specific. I did find a PDF for one of the three published procedures for plants in the Fabaceae from the Association of Seed Analysts, but am unsure if it is the right one. I have yet to find access to any protocols for seeds from plants in the Brassicaceae.

We have used both foil and plastic vacuum sealed pouches for packaging glassine envelopes prior to storage in the seed bank freezer. Are there major advantages to foil vs. plastic? We have used foil historically, but have also used plastic. The benefits to plastic that I see are not just that it is cheaper, but also that you can customize the size of your pouch more easily. Sometimes we have a very small collection and don't need a full foil pouch and sometimes if we have bulky seeds, it's helpful to make a slightly bigger pouch.

I visited NLGRP in Fort Collins this week, and they showed me their new microscope software (for their Keyence microscope) that had lots of fun bells and whistles including software that has promise for counting seeds and pollen through the microscope. Does anyone currently use digitial seed counting as part of their currently seed bank methodology? I'm mostly curious if anyone has worked through all the hiccups and actually put it into practice.

I'm curious if others have insurance policies for their seed banks. Our herbarium collection has additional insurance so it seems like seed collections could as well. Does anyone have additional insurance for their seed collections? How do you apply value to your collections?
