Wheatgrass potting soil PLEASE HELP!

[Guest guest]

I have almost everything I need to start growing my wheatgrass. I

started soaking my seeds.

 

I am having a hard time finding bulk organic potting soil without

animal manure. Bulk is more economical for me. I figured out the

price per the little bags and it's way too much of a cost for me. I

talked to this dirt guy about organic peat moss and he said that all

the professional greenhouse people buy just straight peat moss and

was trying to talk me into straight peat moss and not to worry about

adding anything. I was thinking about adding `natural' perlite. I

understand there is no such thing as `organic' perlite since it is a

rock and not alive. Is that right? I also found bulk organic top soil

with sandy loam, redwood compost, and mushroom compost. I was told it

was very heavy, but of course mixed it would be lighter, but would it

be light enough? The wheatgrass book suggested 40% top soil and also

50% peat moss and 10% vermiculite or perlite. The dirt guy said that

it must be an old book because vermiculite is not good. Is that true?

Anyway should I go with 100% peat moss or add a little perlite and

should I also add some top soil as mentioned above? Please be

specific, if you can, with your help....pretty please. ;-)

 

Also I plan to use kelp.

 

Thanks in advance. :-)
