City of St Petersburg Soil Builder Review

I recently purchased 6 cubic yards of St Petersburg's Soil Builder.  I was so excited to get it, as it's the most affordable solution for bulk soil available locally, so I am sad to report that I don't care for it at all.  It holds a TON of water, which isn't a bad thing here in Florida, but there was a huge adjustment period and I lost many, many plants due to overwatering because the top 2" to 3" are completely dry, while deeper down it is a soggy mess, which makes it nearly impossible to balance seed germination and crop irrigation successfully.  Where I've used it strictly to grow crops I find the plants are stunted and all the leaves die off.  The Soil Builder gets compacted easily.  But the absolute worst thing about it is it is FULL OF GLASS SHARDS.  While I feel the soil builder is a decent solution for some projects, for example laying sod, I hate to report that if I had it to do over I would NOT purchase it for my garden.   Now I have to basically start over to create a loose loam in my garden beds.  *sigh*
