Reusing medium.

Hi guys. Can I reuse my canna terra pro? Do I need to do anything to it other than take out the old roots? Thanks

Yes, you can. But the fertilization will be done. You'll have to treat it as a used soil afterward, and supplement early growth with fertilizers.
On the right is my flower room, in the middle is my veg area under fluoros, left lower my clone and mother area, and left and above is my soil regeneration box.

Yes. I reuse soil and coco as do many other growers. When reusing soil I amend it with an organic fertilizer and other amendments then bag it up and let it "Cook" for a couple months. With coco I just rinse it well. I never have any issues. There are some that just top dress and replant in the same pot.

You'll get different answers with some saying that they'd never reuse soil. But it's done by many with great results and no issues so it can be done. I do it because it's a waste to keep buying soil if you don't have to.
