I have a question on other sites that explain how to make them they say to use a covered dish to wait down and block out light for at least 3-4 days. So I bought two 13 x 9” foil cake pans the kind of throw away, and I put the COIR in the one I made little holes in. I put that on top of the one that does not have holes. Then I took another one and put it on top of the peas that are on the COIR and put a gallon of water on top to wait it down and I wonder if that’s sufficient.? don’t want mold growing in there because that would just about kill me to ingest any kind of mold. Please I would appreciate any advice you have.
I'm not 100% clear on your set up. (I just can't quite see it from the description) You have 2 foil pans, one has drainage holes poked in it and it has coir and the peas in it? A second intact pan is below it, to hold the water? Then you have a third pan, filled with water that is put on top of the peas?
If this correct, it really is more than is needed, at least in my experience. Once the peas are fully soaked, they just need to be kept lightly damp until they start sprouting and don't need full dark. They do like it cool but only need it a bit humid, not full wet.
If you like the foil trays, the stacking them with one having drainage holes should work. It would make it easier to keep things moist with less frequent watering. You could just have the third one empty and upside down, as a lid on it, but it would only be needed until they start sprouting. Bulldog clips would hold it on, if it is in a space where it could get knocked off.
Keeping them cool and not too wet will prevent rotting, at least as far as I have found. Once they are fully growing, they don't need as much humidity, so they do better in an open container with light.
Not all "molds" are bad. As I said above, I found a huge difference between using inoculated potting soil and coir. Peas really do SO much better with a mycorrhizal partner in their growing medium. They also really need soil, unlike some sprouts that do fine with just water.
With the inoculated soil, I got almost 100% germination and so no rotting seeds. With the plain coir, it was much lower and they struggled so it was harder to keep them from going bad. I opted for letting those trays go a bit dry, rather than risk the failed ones rotting and it worked enough that we still got some good harvest.
Overall, once they are sprouting, keeping them dryer seems to be best. They put out strong roots and they need damp, not the main pea section. Potting soil, with a bit of pearlite, does work the best for me since it holds and does a slow release on water.
