Its nothing special but it will feed them those first precious 8 days that can be difficult with coco and cut down on some of the Cal/mag in the beginning.
1. Dehydrated rinsed coco brick (8L)
2. 1 cup worm castings
3. 1/2 cup gypsum
4 1/4 tsp micro (I use great white)
5. 1/2 geohumus (optional but awesome stuff)
I mix the ingridents the same day I drop the bean in the water. By the time the seed splits the coco is ready. The geohumus holds the shit out of water. Its basicly a dorm mix. Everything there can be bought in small packeging and easily carried up apartment stairs with raising suspessions.
