I'm about to begin my first hydro grow. It will be a DWC. The number of plants will be 6-10. How much PHup PHdown should I keep on hand per grow? A quart each? A gallon each? More? Thanks
A quart should be enough for the first grow but I would recommend getting the gallons if u can since it will pay off if u continue to grow
Hi.. I'd just get a qt of each until you figure out which you will need more of. I use the Lucas Formula (General Hydroponics) and use more up than down. When I mix the nutes, they end up around 5.1. I add up until I get it around 5.8, which is where I want it. Other nutrients may raise the ph and you would need the down. So you see you really can't tell until you get going. Good Luck!
