Currently using Canna Hydro (hard) water nutrients and it works quite well. Just wondering if there is anything better that you would recommend? Using grodan delta 6inch block and clay pebbles.
Highly appreciate your advise!
If this method is working well for you I would not change too much, have you tried to place an AirDome in the base of the pot and cover (just with pH stable clay pebbles and then place your 6” Grodan rock wool block on top of the bed of pebbles….. pH in res should be around 5.8…..
