i cleaned the whole thing out today, what a horrorshow in there... i used bleach to disinfect all surfaces and then hydrogen peroxide. i haven't added any to the reservoir because i only have the storebought 3% solution. i heard this kind wasnt optimal for plants, i plan on getting the 35% kind tomorrow..
aso i am using Nutrilife's SM-90, which was recommended by the guy at the indoor garden shop.. it says it's good for all pests & diseases especially pythium. besides that the only other things in the water(i use distilled) are: gh flora grow, gh flora micro, and superthrive. lots of superthrive rite now-1/2 tsp/gal. (ag has 1 gal reservoir)
asfor airstones, i have 2 aquarium bubblers going, one is small, the other is larger w/ 2 airhose ports. so i have a total of 3 bubble sources in the water rite now.
i cut some of the roots off, and the lower leaves that went chlorotic. now we play the waiting game and hopefully she'll(it is a she btw otherwise i'd just start over) recover.. im really not satisfied with the aerogarden at this point, i think they couldve designed it better in regards to the reservoir. its hard to keep cool and it gets grody fast, lots of nooks and crannies for mold to grow. all you experienced folks are gonna be like, "so your res was at 80F for a week and you have root rot. gee." but it's all good im still learning about this whole hydroponic thing, i guess i just hit the curve. i had an airstone and i was changing the water every 4 days, (ya pretty much have to do it in the dark so your roots dont get exposed to light- rrgh). but i guess i also fucked up by sprouting new seeds in it after the first seedling had grown to 5" tall, i think cuz they were so young the pythium was just like, "alright, dinner!!" and wiped the little guys out and then moved on to my main one. it's about 7" tall,showing some gorgeous pistils, and im hoping it is healthy enough to pull through.
i kinda wish i'd have built my own system(cheaper!!) but oh well this is my first grow in 5 years and i was never an expert in the first place, so you learn as ya go. thanks knowm for the advice if it wasnt for this website i'd probably be way behind. i'll let ya know how she's doin this week
