so, making progress:
Mixing potting soil and and filling pots. After 5 years of building garden soil from scratch, river silt with yearly applications of humanure compost, it's beginning to look pretty good. My window grow this season is telling me I don't need to add too much to the base soil. This is what I'm doing:
for a 3 gallon pot, added to garden soil.......
2t 9-3-1 bat guano
2t 0-7-0 bat guano
2t 0-10-10 EB Stone Organics Ultra Bloom
2-1/2 cups worm castings
3 cups pearlite
1/2 cup Blue Sky biochar.......
the guanos, ultra bloom, worm castings, and pearlite thoroughly mixed with soil, and pots filled. The biochar is sprinkled on top of pot and well watered to soften and crumble, it comes as elongated hard pellets. Then it's mixed in.
got 10 pots filled yesterday, back at today. Weather is primo, warming to upper 50s f daytime, probably 75-80 in greenhouse, I'll check this today. Last night only got down to 39f in the greenhouse, moving right along!..
