I have been growing Kang Kong in a plastic tub that has no holes in it to keep it consistantly moist. I filled up the tub 3/4 full with potting mix, aged cow manure and blood and bone. Once I had my seedlings ready to plant I put them in and then filled up the holeless tub with water to above the soil mark.
Whilst my plants are growing magnificantly in the tub with constant water, I have noticed a green slime/algae that is sitting on top of the tub at the water mark. My questions are;
1. WIll it be a problem growing this plant that is sitting in stagnant water (the plants don't think so) and
2. Is it safe to eat the produce.
I am trying to keep the environment similar to its native habitat in SE Asia and so far so good.
