What ratio did you find the charcoal to be most effective in your grows?
I guess lots of people have been mixing charcoal into their compost heaps. I have put a good few shovels of charcoal into mine.
actually im doing it a lot different than you. heres what i plan to do.
i mixed a few gallons back hmmm 2-3 weeks ago. each started with a base of castings, soil from outside sterilized in the oven, and perlite.
i am doing 4-5 mixes.
ca= castings ch=charcoal(natural from nature i gathered it up from about 4 different species and mixed equal parts) ach=activated charcoal pe=perlite ss=sterile soil
(these are estimates i do not measure)
then after a 2 months has gone by i will make another batch. so one will be aged two months. then say another 2 months ill make another, ill have a 2 month, 4 month and a fresh one. this is to see if age has anything to do with it. i might even go longer im not sure yet depends on how much room this is going to take.
after that i will probably start clones to throw out genetic differences.
its a long but patient way of doing things, but the results will show in time. its a side project anyways, way too much breeding, and composting experiments to do.
