Wanna know if you have to PH the water in order to flush the system , or you could just use hose water and then at the end ph the water ?
Or you have to flush with PH'ed Water ?
It's hard 4 me to get PH down so I have to save what little PH down I have , but if I have to , I will .
Let me know .
I grow in slabs and trays with a 40 Gallon reservoir.
