Hey guys,

has anyone had success in making seed raising mix for annuals without buying products?
My homemade compost is a little sticky (like worm castings) so I add perlite to increase drainage and aeration. It works great but I want to avoid buying things wrapped in plastic. Is sand the next best option?

I have never understood the fascination with perlite when there is vermiculite around which is simply heated mica and provides minerals and  holds water, instead of being completely inert like perlite.

Sharp sand can be mixed with vermiculite and compost to make a really good seed starting medium.
The ratios are 1 part compost to 6 parts sand and 1 to 2 parts vermiculite if desired. The vermiculite will hold water and reduce the amount of times you need to water the seedlings once they are sprouted.

Many people simply use sand and mist about 4 times a day if uncovered, some folks like to use a cover to reduce evaporation at the surface.
