I just apply the ph down or up into the blue level tube whenever I need to adjust it. If you have an airstone in the reservoir, it will mix it up for you and just check the ph about a half hour later to get accurate reading.. after a while the plants get too big to keep lifting them out of the reservoir bucket so just adding the ph adjuster throught the level tube is just fine.
SAP420 Reviewed by SAP420 on . changing ph?? If I'm using a single waterfarm can I add ph up or down to the overflow tube....? Can I just drip it on the hydroton, or do I need to lift the grow chamber and add to the bottom res directly. May be a dumb question but I wanted to know for sure which method was best so I can avoid trouble later. thanks Rating: 5
