Project AeroGarden

MYSTERY SOLVED!!!!! So shortly after I started this project (think day 12-15) I started noticing rust on a leaf. A fellow peraon on this group told me they had tryed AeroGardens before but would always get rust and eventually the plant would die. So me being me, I spent the next 12 days reading up and trying different things to fix this. First everyone was telling me its cal-mag (go figure) but I was already adding cal-mag, so I increased the amount, nothing. Next I was told it was from a dirt grow space, so I cleaned it up a bit and still nothing. Then last week while working on it I noticed my tank temp had gotten higher then I would like it (25c). So I added cold water to it and got it below 20c (17c I believe). Then after I did that I started thinking about the temp of the tank, looked it up, and sure enough water temp in DWC needs to be kept low around then18c mark to stop harmful bacteria from growing in the tank. Started keep the temp below 20c and bomb rust stops spreading!!!! Now to figure out a way to keep it cold constantly without me having to drain it and refill it. This is proving to be difficult due to a heat wave we just got hit with. Temperature outside has been hitting close to 38c and inside the house has been hitting close to 30c and warming my grow box rite up. When its colder out (24c or less) everything in my grow box runs smoothly, as soon as it gets higher then that, Temperatures start to sky rocket. Oh well wouldnt be fun if it was easy. Happy growing everyone.
