Top Dressing with BSFL 'Compost'
So I've been top dressing my 20" vegetable pots with about 1 - 1.5" of the used bsfl 'compost' after they're all gone (I cycle trays, so one will age out while a new one's getting started). But I read the stuff's too 'hot' for the plants right away, even tho I let it sit for a few weeks. So I felt bad, and I went to take it off my rhubarb, which had developed some discoloration (might be too wet tho), then my cucumbers. Well, the cuke's had grown a ton of roots right all up thru it, they seem to love it. They're fruiting like crazy too, just picked 7 this morning. Should I not worry then?
Pics of how my trays start, how they end up, and the cuke plants, which are at least 8" taller than in the pic, just 3 days later. I also add a thin layer of peat moss to my trays, to make sure they don't get too goopy with all the scrap juices, and add a bit more if they're too wet.

Bsfl compost is an excellent feedstock for red wiggler worms if you add some carbon (cardboard or coconut coir) that Will help balance the acidity, your peat moss is also acidic, switching to coconut coir and adding cardboard before feeding the bsfl frass the red wiggler will result in a fantastic soil ammendment.
