I figured that too. So sterilizing this soil will absolutely eliminate all the good bacteria. The worm casting and bat guano that is mixed in should still be good though, correct?
Sounds like a great idea. Do you mix the worm castings in, or do you make a pocket and fill it?
My main objective is to have a medium that promotes growth for older seeds. I can get them to pop, but they don't grow once planted. After two plantings failed to grow, I tried some seeds I have plenty of. Those were @Scissor-Hanz G13 x Afghani #1. I used 5 pots that already had a soil center and 3 with just clean CocoGro. When I use coco for seeds and cuttings, I rinse it 2x with tap water and a final time using pH adjusted R.O. water.
Notice how the pots containing coco only (you can tell by the obvious lack of perlite) contain label tags 144, 150, and 151.
Now, at 22 days in pots, notice the difference:
I'd never done a side by side compare of soil and coco with seeds before. I am impressed enough that I want to have a soil that doesn't contain pests for growing seeds. Maybe I'll need to mix my own...
