Wow interesting! To be honest I don’t (yet) use any soil amendments. I’ve just been growing veggies using my own compost and not much else, and then recently did a couple of outdoor weed plants using the same.. they turned out OK but I had to put them up on the roof as it’s the only place that doesn’t have light pollution from my neighbours. It’s a great spot, gets the sun all day and no light all night. Also good for OPSEC :)
Sounds like you’re a serious grower. And sounds like I have a lot more learning to do.. malted barley and sprouted seed teas just wow never even heard of them!
Do you grow other stuff as well or focus mainly on weed?
