Stickanswered grow question 6 years ago Hi! Using guano, you can add about a cup of dung per gallon of water. Mix together and let it rest for ~12h before applying onto your medium. Be warned that chlorine in the water will kill the useful bacterias so make sure you tap water doesn’t have chlorine, or use RO water. Now about the schedule, it’s related to the NPK ratio of your mix, so start slightly with 1 guano feeding by week, you’ll increase the intakes later if the plant reacts happily. Hope this will help, keep us up-to-date and happy growing 👊
