The Neptune Harvest i use has application rates specifically for seed starting (1tsp per cup) and compost enhancement(2ozs per gal). I heard woods chips can lose N during decomposition so I want to combat it, but I've always added it to compost to enhance the micro herd. The nutrient addition is nice, but the boost to the micro herd is where the real benefit is. I soak all my rapid rooters in a mild solution of it, both with seeds and clones. Can't say it helps one way or another, ive never done any side by sides. It's the Frank's Red Hot of my gardens, I use that shit on everything. Indoors, outdoors, compost, nutrient/ compost teas, direct feedings and foliar. I've been wanting to get my fishing license to start collecting fish for my compost. No limits on a few nuisance species around here, so I could catch a bucket of kivvers a day if I wanted. I've heard they're also good in fish stew, just a pain to clean.
