I use lime as an amendment so tilled here. I'm not sure of it's effectiveness as a top dress, I believe it needs to be mixed in to react as a buffer. Not sure tho on that.

I'm sure with your system you would get med grade outdoor. I do 100% organic indoor, BioBizz system, and I'm ecstatic with the results. With all the life you have running I believe it would thrive well.

Your idea about the acidic compost tea would probably work too. If the soil ph is 7 and you come up with a concoction around 6.2 it would probably balance out nicely. I'm sure someone with more outdoor experience than me will show up, I'm just interested as hell in the whole living garden idea.

I'm sure the quality of your outdoor would blow away the hydro. Natural sun to activate all the terpenoids and flavors in the plant, my mouth is watering just thinking about it. Not to mention all the free UV making the plant give up all it's crystally goodness to protect itself. Let me just stop now.
