Supplement suggestions

I'm looking to start an aeroponic system and need some advice about which supplements are better than others

Supplements are not necessary. Save your money.

Wow

Good luck

silica is one that actually does something and you can use it instead of a ph up. Wish I knew that years ago-it's way cheaper then ph up and plants actually use it-win win

Remember though, silica products need to be diluted first to avoid chemical reactions and unwanted precipitation. That's why prosilicates and silicic acids are always added to your res first, mixed well, and then other stuff is added. So what's cheaper? You shouldn't need much pH up ever unless you have crappy water or a bacteria imbalance.
