What compost mix do you use for your seed sowing?
Depends on the seed. I mostly propagate species that are indigenous to North America with carnivorous plants being the forerunners. I have played with ornamentals in the past for the experience but I admittedly waste them after I am done experimenting. I have a mortar mixer and large bins of assorted composts, Turface MVP, peat, gray pumice, perlite, vermiculite, Hydroton, charcoal, assorted chipped wood and bark, etc. that I use when creating my own medium.
I like loamy composts.
I've been pushed out of the kitchen into the greenhouse for starting seed. I used to have a water source when I worked in the kitchen and always hosed down my medium before I re-filled. Didn't have the water line in for the greenhouse so I was tapping down the medium on the table when I should have started hauling water back there. I paid for being lazy. The water line is in to the greenhouse now. Still needs to be hooked up but with the work I created for myself this past season, I'd probably buy a 100' hose to get water back there to avoid having to transplant seedlings prematurely.
