i love that expense omri. that must be the kicker
talas, in my experience unless you pay way a lot for hydronutes you're going to get about the same performance with most good brands out there. with a few differences in the plants here and there, it's just some are more modular or require other things that aren't specifically 'fertilizer' but definatly hydroponic solutions to go in the res. or watering etc.
