I mix my DM nutrients in 4 litre batches. how much oxy plus (17.5%) should I add?

i use it at 1/2ml per litre but thats due to res temps going to 24c...dont like the idea of adding H202 to my plants but needs must...

as soon as the temps max out at 22c then i will drop it completely...if you have airstones and no temp issue's then i wouldnt bother with it at all...

Unless your roots are looking a bit iffey, just use it to disinfect your system

HERE ya go dude

thanks OeN. res temps are an issue so thats good advice for me. I've been adding 1.5 ml per 4litres so quite close to your recommended amount.

thanks turnip, but as OeN said; res temps are a prob just now so I wanted to keep the nasties at bay.

Thanks bartman. all I could ask 4 and more.
