Project AeroGarden

so this last week was going great, had kept my res temp low, and my rust was basically all gone. Then I had to go away for 2 days to help my dad set up his 2 grown tents. I had my significant other watch over everything while I was gone. Unfortunately she wasn't able to keep the res cold enough while I was gone and the started to come back. Its so far only on 3 leafs that I can see. I also taped up the openings where the probes go into so to help cut down on light and heat getting into the res. Never grown a Dwarf plant before and it is growing super slow, like a inch a week almost lol. I know that the max hight they can get to is roughly 24 inchs but at the rate its going i don't see it getting that big. My nutrients levels slowly drop between 30-50ppm a day, I usually drain it out every 4-5 days and drain and refill it. I try to do it before the ppm drops more then 200ppm below what it was when I mixed it up. The trellis that comes with the aerogarden is just a basic plastic ring. So I used twine and turned it into a net so that the plant could have more support. Hopefully it works lol Happy growing everyone
