Im setting up a watering system. thought it would be fun to try to something with high P values. Not necessarily the "fastes" way got get nutes, its just play to begin with.
wood ash has much K but not so much P and I find a lot of organic stuff has plenty of N but less P for nutes. I want something nice after the strech.
Organic sources of bio-available P are few and far between. The carbon footprint also tends to be very high with them. Most cannabis growers overuse it and it requires extensive flushing to rid the root zone of excess phosphorus in the final product.
Composted cow and horse manure are roughly the perfect NPK for cannabis at 2-1-3 ratio.
Have tons of compost with pig, cow and maybe some horse too. Together with straw or sawdust. Got different ones. But I have one strain that I need to starv for N, but just that:/ so then I started thought about burning the N away from chicken manure. Burn compost? LOL
