On my latest grow, I added activated charcoal that I got from an orchid grower. $20.00 per 50-lbs. - fair enough.
They're at Day 25 and things look great. I'll report as they move through the flowering process.
Cheers!

I buy activated charcoal through a local orchid growers club - $22.50 for 50 lbs. - those little old ladies haven't learned the 'grow store' paradigm of buying low and selling at stupid prices yet.
yes, I guess that any soil rich in castings, mychorrizzae and beneficial bacterias can go on forever without needing to be changed. The important thing is not to let such organisms die by keeping them with enough food. Such organisms are so powerful that you can cut a plant and let the roots in the soil, give a week and you won't be able to find any dead roots, all of them will be decomposed by such agents!
The thing to watch out for is the use of particular agents like hormones: I know that for instance, if you use products like Bushmaster and Gravity in soil, you might not be able to take them out of the soil. Since they are products which inhibit growth or fuck up vegging plants, you might be no longer able to reuse that soil to sprout seeds. Also that aspect perhaps could be "fixed" by using hydrogen peroxide and other products and bacterias, if you use the first though you'll have to rebuild all the living organisms, as they find it too hot.
Hey Ripman on the hormones. I noticed hormones
can get an OMRI rating & they use them in Superthrive &
lots of other stuff.
How bad r they? for soil? thanks.
What are the pottery shards adding in terra preta?
Is it just aeration? or more? thanks.
Wouldnt crushed pottery be their version of perlite? Thats my thought.
As for the microbes thing the char acts as a breeding ground for the microbes and stops them being washed away with rain/watering. I understand it also allows more NPK to be stored in the soil. This is especially useful i reckon when using more of a hybrid soiless medium such as coco with a small amount of compost/soil for the biolife to cling on to.
