Propagation: Mold on indoor seedlings, 1 by Pfg

I always over -water as I use capillary matting in self-watering trays to keep the maintenance down. I start seeds in two locations, a chilly city window in the early winter months. When we have a really cold spell my window garden can get down to the low 60's. When we open the CT house around the end of March, I start seeds there, too. We leave the thermostat at 60 degrees during the week when we are not there. The first year trying seed growing at the house I had terrible losses from the combination of wet, cold, and low light. Thanks to the generous sharing of knowledge by so many great gardeners on DG, I have learned a few techniques that have made all the difference.

The second year I added a T-5 light and timer and a heat mat. Now I have several in both places. This year in the city for the first time I added a thermometer to regulate the temp.

I water with 10:1 mix of water and peroxide. i use this mix for everything- moistening the soil, regular watering, filling the trays. The extra oxygen molecule helps feed the plants and prevents pathogens from growing. I don't worry about sterilizing anything any more.

My last trick is to sprinkle cinnamon on top of the soil after sowing or potting up, which also works well as a fungicide, and prevents gnats.

I now have an excellent success rate. Pic one is the city garden this week.
