Metal versus Plastic Lids

First of all when speaking of metal we should declare that we intend to speak only of stainless steel.

The wire mesh used in your windows may be aluminum.  This is not a good idea when working with food.  Do now use aluminum for making sprouting jar lids unless there is nothing else available. If you find yourself in the aftermath of an atomic war or a soccer match gone horribly wrong, then use whatever you can find. But given a choice, lets reduce the chances of Alzheimer’s disease by staying away from the aluminum from window screens.

The reason I like wire mesh (stainless steel) more than plastic is because water goes through a wire mesh lid easier than plastic. Scientifically this is caused by the larger meniscus of water in proximity to  plastic. Plastic is more hydrophobic and basically gives water a hard time. Not very scientific, but the real explanation would involve formulas and graphs and experiments. So I figured, dump the formulas, dump the graphs, and just do some experiments if you are interested. And, you should be.

Get a plastic lid with holes near the same size as the wire mesh we are using. Try rinsing seeds in a jar with a plastic lid versus rinsing seeds in a jar with a stainless steel wire mesh.

My experiments in this realm indicated that getting the water in and out of the plastic lid was a pain in da rear — unless I used larger holes in the lid. But, then my seeds would slip through the holes.

Ideally you want a lid that will let water come and go easily so you can rinse the seeds, and yet, keep the seeds in the jar. It is no good to get water in and out easily if the seeds pour out too. And it is no good keeping the seeds in, but not being able to rinse the seeds through the lid’s plastic mesh.

Do the experiment. You will find plastic works great for beans and larger seeds. But, the plastic does not work so well for small seeds.

I have not found a seed that will go through my stainless steel wire mesh — knock on wood.
