Bio-char is good stuff, if you need it. Just make sure you sterilize it in the oven first to avoid introducing unwanted pests.
Soak some in water to see how it affects pH, although the high pH of wood ashes will probably be leached out by now (130 years in a Canadian forest).
I'd start with a cup per gallon and work from there. Although, in a rich soil mix adding more things doesn't necessarily equal more results.

For example, bio-char is noted for its effectiveness largely in part because the surrounding latosols (tropical clay-type soils) are so poor in nutrients and structure. Adding it to, say, the Rev's recipe or TGA super-soil mix would likely have minimal benefit. The soil is much richer than anything in nature and has great structure already.

Also running deep water culture still being setup tho.

Lighting:

time - veg 18/6 flower 11/13

Nutrients:
Nectar of the Gods... i'm looking for another line of nutrients do you guys have any suggestions? Organic suitable for deep water culture and soil mix.

Will update with pics soon, gotta get a new SD card.
