Good question! I'm using a mix of Miracle Grow soil for roses, some Hyponex organic humus/manure and Schultz's potting soil for indoor growing. I didn't follow any recipe but I think I might have guessed right enough to grow what I need. I'm sure there's a lot I can do or undo to make a better mix but I need some good advice. I already have the three main ingredients and I'm wondering what else I can do. Any ideas?
half ji#2 and the rest a mix of perlite and vermiculite canna terra nutes. i wudnt add bone or fish, seedlings dont need it and as u will have to feed and water the plant often anyway i find it no hasle and i get better results and root growth giving the plant the majorty of its feed in the water.
