i dont know about any "homemade" nuits and im assuming this is a soil grow personally ive been using this stuff called "rainbow mix" comes in a "grow" and "bloom" mixture it has mycorrhizae (simbiotic root fungus : creates massive root system) u just mix in your soil or put on top and water in ( i would suggest mixing with a little wet soil if u cant mix it in then watering in as it can be very dusty) anyway it all organic and seems to be working well. i purchased at the grow/hydro store in next town but it can also be orderd through hydrofarm catologe only costed 10$ per each 3 lbs of the stuff and each bag mixes with about 50 Gallons of soil. as well there are types of bat guano that have diff nuit levels. hope this helps !
