thank you for the response.
So you are saying many indoor gardener's use water straight from the tap without altering it in any way. I have read on numerous occasions that tap water contains chlorine, which the plants dont like, want or need, so the way to remove the chlorine is to just let the water sit for 24 hours, I've read this numerous times (this is an example of conflicting advice provided)on various boards. No need to remove the chorine? Just mix tap water with your hydro nutes, check ph and then water? Can you clear that up for me? thanks
i have used straight tap water, from multiple city tap sources. all i do is lower the pH since mine starts off quite high. Sometimes I get mag def, but that is what cal-mag is for What i am saying though is that a RO system is ALWAYS better, then you always know what you are putting in (just the nutes) and there is no random shit.
About the chlorine, it is a common misconception that chlorine will simply evaporate if you leave it to sit. SOME of it will gas off, but in order to get it all to gas off, you need to agitate it for that 24 hrs, and that should get most if not all in that time. If you leave it for a few days (3-4) without agitation (airstone), most of it will gas off on its own, but certainly not in 24 hrs
Also, as a side note, some areas are now using chloramine instead of chlorine, which can gas off but takes much longer (around a week of agitation). You can call your city water system if you have a question about that.
PERSONALLY I don't remove chlorine from my tap. I mix my tap and my nutes and adjust accordingly (although in my case most of my nute regiment ends up putting my pH right where i want it). I probably should spend more time removing the chlorine, but so far in my couple years of growing on city water I have not seen any noticeable problems. RO system for christmas tho ... thanks santa
hope that helps,
