The Sunshine Kabocha are clearly up. They look strong and vigorous. The other half are Cha Chan Kabocha. They are starting to emerge.
I like this starting box. It is just a plastic container with a hinged lid. The lid lets me lock the moisture content into the box. I haven't added any water since making the soil blocks. I don't think I'll need to until I put them out, next weekend I think.
