Good Medium For Starting Seeds

While having grow lights is crucial for starting seeds indoors, everything about the health of a plant is rooted in the soil.

Seeds require a growth medium that provides plenty of nutrition, holds moisture, and provides the proper environment for sprouts to develop. While you could use soil from your garden amended with compost, it isn't likely that you'd see the type of results you would want.

A good mixture that was shared with us a few years ago is:

• One bag (40 quarts) Bruce Miller Nurseries Lite Potting Soil
• 5 quarts compost
• 1 Cup blood meal

We typically add some dried molasses and epsom salt (for the magnesium) as well. 

I'm certainly no expert on soil. For that I highly recommend The Dirt Doctor. I can, however, say that we've had tremendous success with growing plants from seeds using the mixture.
