can anyone recomend some good nutirents for soil. Also does bat guano help? is there a formula to know how much bat guano to use in my soil?
The formula I follow is Fox Farm nutrients (all organic), but there are many good nutritive systems, yes systems, read the label they might say use 2 or 3 different ingredients. Fox Farms uses 1 for vegging, and up to 4 in flower.
There are lots of soil recipes, but bat or seabird guano, worm castings, and seaweed products are popular. There are diff types of guano for different stages of fertilizing. Blood/bone meal is too creepy IMO.
