Always use Bat guano. need something else?
Hey bro! I use a mix of bat and seabird guanos with an NPK of 2-15-2. I like it because it has no smell. I take 100 grams of the dried guano and mix it with 2 quarts of hot water, stirring it with a plant stake until it is almost all dissolved. I then take an 8-ounce cup of the tea and add it to 10 liters of water with a pH of 6.6. I water the beds twice a week with this tea, waiting until they are dry before applying it. I keep doing this until the middle of the seventh week in 12/12. I like to give them a good flush with water for two weeks or more before harvest.By using natural nutes like bat guano for phosphorus and nitrogen, I've eliminated the need for pot-specific growing nutrients — but that doesn’t mean the growing process is any easier. It took me a few tries to get the soil down, and each batch takes about thirty days to mature. It takes patience. Brewing my own compost tea is also a never-ending learning experience. The nutes made it easy. Everything came ready to add in water. But if you want peace of mind, you have to do it yourself... At least you have to try and see how it goes.
Bat guano is the best! Grew my tastiest buds with this, i would always use in a soil grow. My favorite was Budswell but can't find it locally. Also earth worm castings as top dressing and transplant time. Good luck!
