You can really push the herd in the right direction with the teas. And indeed, it does allows one to stretch the base ingredients a lot more.
This product has lived up to its billing. It contains vegetable compost, worm castings, kelp, and minerals. So all you have to do is add molasses and
voila!
I use a little under
1 cup per
7 gallon batch of tea, so
1 cu ft goes a long way for me.

I'm lucky to have access to relatively cheap worm castings, and with every wheelbarrow (deep contractor) of potting mix I add
2 kg of the stuff.
I remember reading a multi-crop study with data suggesting there's a sweet spot for worm castings in the potting mix. It was surprising that the optimal amount was a fairly low percentage by weight. Around
5% or so if I remember correctly, maybe even
10%. I'll dig up the study.
I also add the soluble herd from
fungi perfecti when I pot up seedlings. Stuff works.
