The big concern with using compost in seed starting is all the natural bacteria and fungi it contains. Great stuff for the garden and established plants but potentially hazardous to very young seedlings.

Both damp-off, a seedling killer, and the most common tomato plant diseases are fungus and bacteria caused so IMO the risks far outweigh any benefits when it comes to seedlings. That is why using a sterile seedling mix is usually recommended.

Then add to that the consideration that without those active soil bacteria the nutrients in the compost aren't available to the plants anyway so even the nutrient benefit that is claimed with it is lost.

Just some things to consider.

That makes a whole lot of sense -- I think I'll stick with the tried and true.

Thanks again!

If we build compost, which is done with a âÂÂlayer upon layerâ system; it can help accelerate the decomposition process. Hardware stores, garden centers and nurseries; supply the ingredients used for a compost bin. If you throw in a handful of ready-made compost with the microbes inside; then it will give your compost a boost.
