well i can't say from an experience point-of-view that they do but it says in the grow bible that its an EXCELLENT source of N and should be mixed as accordingly then it must be good.. I will give it a try on my crop and prehaps report back.
tekneeqs Reviewed by tekneeqs on . What's a subsitute for P? SInce human urine is a good source of N (nitrogen) and should be mixed 1 cup to a gallon of water. I was wondering, what is a good source of P (phosphorus) to feed the plant when in flowering stage? Something practical that I can find around the house? Thanks Rating: 5
