co2 boost= way overpriced
odorsok= I like mine! It's a great size for a hobby grow!

You know that distilled water will not help you? It has NO Ca IN IT!!! Unless you run calmag, do NOT use distilled or RO water; use tap. And Serenade won't help, because it's not a fungus... *sigh...
stinkyattic Reviewed by stinkyattic on . Rust - Black leaf spot mold help! So far ive lost 2 plants to this problem and more on the way. Ive been using serenade every 3-5 days with some success but it keeps coming back. Will i have to keep spraying the plants for their entire life cycle or will they eventually fight it off? What else can i try to combat this problem? i have a sulpher spray, and am considering trying the baking soda method if someone thinks that is a good idea. im hoping someone experienced with serenade can chime in, it seems to work Rating: 5
