Propagation: Dr. Deno's books are now in the public domain. I did try a layer of coffee filters but the results were inconclusive. I understand. Agreed, anything purchased by labs would be impractically expensive unless you had grant money. They tend to be even denser and smoother than coffee filters, so i would expect even less root pentration. Since they are smoother, i wonder if they hold the humidity as high as paper towels (which have lots of surface area.) But if the deno bag is sealed, I; 'm sure RH would be 1. ![]() ![]() News paper would quickly disintegrate into pulp once wet. Good point.

But do you have to let CO2 out if you keep seeds in a plastic bag for a long time?> > using a Deno Bag to send seedlings through the mail, Great idea! But if oxygen diffusion is needed, maybe the bag needs a small hole. Or can it migrate through ziplock plastic? Water can, VERY slowly, and that's more polar than O2. From what I read, adult roots are happy inside wet plastic, but adults leaves and stems tend to rot. I wonder if they need to be drier, or have more oxygen, or both? Would sedling leaves resist rot longer?> > One possibility would be to cutup a polyethylene jewel case used to ship CD’s but even that may be to complicated.

The idea of a CD or DVD mailer is appealing, but I think the trick for "business envelopes" will be a stiff envelope + padding around the edges to hold the rollers apart by 0. This gap should be near the center so the rollers are most likely to miss it or be supported above it.(The total thickness must be significantly less than 1/4" or they will reject it.)Someone suggested that UHaul sells thin foam for packing china. I figure I would make the envelope itself out of thin chipboard like cereal boxes or Fed. Ex overnight envelopes or USPS Flat Rate Large Envelopes.
