Thanks man, yeah I re-use my soil.Anything I've used goes into a tote " to be recycled " and I keep the lid partially propped open on a corner to keep it aerobic..Anything I use in the brew bag on current grows when making teas goes into that tote or separated between that tote and another I'll have on standby to be reamended.Usually just adding those keeps the activity jumping in turn creating warmth that makes the tote lid and walls sweat keeping the medium moist..Ideally, you'd want to keep the medium within field capacity and if things just so happen to dry out I just moisten it every so often and give it a few flips and pop the lid back on..I have one tote from the beginning of the year that is probably drier than it should be but no worries..Once I hit it with an enzyme to break down then pieces of roots I broke up,I'll re-amend it then hit it with a good tea and it will be popping again..Some microbes may have went dormant & some may have died but the dead provide food for the new arrivals.
