Yeah, its a tough one but I think I'm getting the watering thing down. I've also started taking my trays outside on cloudy days until my greenhouse is ready Then, my wheatgrass should be awesome!

A question about kelp powder though - when I add it to my watering water, it sinks to the bottom. When I sprinkle it on top of the soil, they're the spots that tend to mould first. I'm not sure where my kelp meal comes from, I just bought it from the healthfood store in Calgary. Am I supposed to use some special seaweed extract in liquid form especially for this purpose? Surely not...

Anyway, I read that the suface mould (I get two types: cotton and green) are not pathogenic so not to worry about it too much. Do you agree?

Thanks for your time
