My veggie seedlings sleep in my YOLO Compost Tumbler at night to benefit from the warm, moist and humid environment. These broadbean seedlings are 2.5 weeks since planting. Nights are getting much colder as winter sets in. I’ve found that my seedling trays don’t dry out.
This shell contains mostly grass cuttings and dry shredded leaves with kitchen waste. The shell was started about three weeks go. The mix actually started off too dry but with the almost daily addition of kitchen waste the moisture balance is getting just right.
