Recycle, and reuse for sure imho.
All soil gets reused here, always stays inside, minimal pest issues that way. Still have the soil from my first grow. Lmfao.
I haven't bought any soil/medium for quite awhile, have around 200-250 gallons worth of it I cycle through over and over.
I do all ROLS with mine, there's always a few totes cooking away.
All rootballs and plant materials get dumped into a large tote with other reused soils, amended with what i feel they were lacking in, along with a few other always added ingredients like EWC.
Then it gets shelved for a month or two, and I let nature do it's thing.
Its a very dark, soft and fine mixture, very earthy and pleasing to smell. At this point though I can't say what its composition is. Lol.
The times I have added new material to the mix it's been 1/3 peat with some coco, 1/3 good organic compost, and 1/3 lava rock/perlite for aeration.
For IPM of the new mix I spread that all out on a tarp on the garage floor after mixing, then hose it all down with a spino drench, and or final stop to kill any eggs n shit in the new batch.
I let it dry some and then add in the amendments like bone meal, kelp, gypsum, lime, alfalfa meal, crab meal, etc, and remix well. Finish loading totes about 3/4 full, wet them good, and shelve them for a month or two to cook.
I've tried some no till plantings as well, taking the fresh harvested plants pot, and transplanting a new rooted clone right next to the old root ball with great results. Always top dressing a week or so later once it's established itself some.
Have found I prefer ROLS, and shredding them into totes though. I like to see how the root structures formed as I disassemble the old root ball for reuse. All root materials gets turned into the soil for new compost.
I've found this method to be easy for me, inexpensive for materials needed, and can grow some darn good herbs.
