Hi, considering switching to canna aqua from canna hydro soft water as it's more tuned for NFT, but aqua description states for mid range water hardness only. Should I switch being in a soft water area?
The normal Canna Hydro soft & hard water feeds work well in any hydroponic system. The Canna Aqua is a great product, but we don't sell lots of it as it is more specifically designed for Dutch water, which is slight to moderately hard, and as such works great in Dutch water, and also works great in English slight to moderate hard water. Unfortunately, people do have problems with it in soft water, and have found the standard soft water Hydro to work better. Also you might find in your soft water that the Aqua drops your pH too much, I would recommend as you are in soft water that you stick to the Canna Hydro, or other soft water Hydro feed.
