Sunflower troubleshooting - fuzzies & brown roots

[Guest guest]

Hi,

My sunflower sprouts are developing the fuzzies (not the root fuzzies, but white

webs higher up) and they also have brown roots. Is this due to :

- overwatering?

- mold in the air? (there was black mold on the window sills, which I have since

cleaned)

- humidity in the air?

- overcrowding of the seeds?

- trays stacked too long?

I've put a little fan on one of my top sprouting shelves to circulate the air in

the room, and I've picked out a few seeds in the crowded spots, as well as all

the fuzzy ones. I've sprayed them with thieves essential oil as well, as it

kills mold.

I may have left the trays stacked a bit too long (from Monday afternoon to

Friday) because I didn't have enough shelf space available, and am wondering if

that is the cause of it.

I grow all sprouts in soil, in trays with ridges in the bottom, and water them

by lifting the roots and putting water in the ridges.

I diffused some thieves in the room, but since it is a water based diffuser, I

didn't think it was a great idea to add to the humidity. I will put a

dehumidifier in today.

Any other suggestions?

Thanks!
