I dumped three totes full of goat shit and piss straw into a huge pile of leaves and grass last April. It all melted down into 1/4 its volume over the summer.
That soil was HOT. It aged in pots in my garage for three weeks in November before it stopped smelling like ammonia. That's when I dropped in the seeds.
They did great. Popped fast, grew short and bushy. They were so very dark green.
A minor heat event almost killed them in early January. I flushed the crap out of that soil and saved the first gallon of runoff (sits at 6.2 pH, made from 7.2 tapwater). The next few gallons went to a dead spot in my lawn.
The plants completely recovered. They've been in flower for eight days and are growing almost an inch a day. The older leaves are starting to turn a darker green.
The only amendment I added was Epsom salt (low native magnesium). Never a fertilizer, just tapwater every few days.
I can't wait to see how the flowering progresses.
Still, my next batch of soil is 1:1:1 goat compost, recycled garden topsoil, perlite. I still flushed the compost once before combining it with the topsoil and perlite. I am curious if I'll need to add nutrients at some point with the new soil's grow.
