The way I grow I layer Perilite between the medium.
So you put a layer of perlite in the bottom.
Sprinkle bokashi, frass and mycorrhizae.
Then a couple inches of soil then another layer of bokashi frass and mycorrhizae.
Do that all the way to the top.
Fill the whole pot with roots quicker.
Healthier bigger faster growing girls.
Its fungi and microbes that feed your roots for you.
I use air pots but it works in bags really well.
So you can use soil to start.
Once you see the improvement you might want to try coco.
I just blew up your pic. Those clones are perfect wow. :thumb: I actually need them to slow down a bit as the flower tent is full for a couple more weeks and I'm risking these clones growing too big. Flower tent is only 100cm tall:rofl:
