Alright guys, i've had a 6 site 5-gal bucket DWC system running for a couple months now, and i've been having a real rough time. I foolishly bought a cheap system off amazon that came with a little air stone that broke in half about a month in and i've been fighting root rot the ENTIRE time i've had the system, my roots are really struggling and so are my plants. So, to compensate for the cheap system and still water i've been throwing 4-5 frozen water bottles in my system every 1-2 hours to keep my roots alive. It's been hell to say the least and there's no way this will keep working for long, even when i sleep i have to wake up every 3 hours or so to throw new water bottles in because if i left it alone for more than 4 hours or so my roots would begin to rot. Needless to say SOMETHING HAS GOT TO CHANGE. I've decided (and correct me if i'm wrong) but i've decided that i NEED a good air pump and air stones to keep my roots healthy. Here is my system: http://www.amazon.com/Sprayer-Aeroponic-Hydroponic-bucket-culture/dp/B00ALOFDGG/ref=br_lf_m_1000999281_1_6_ttl?ie=UTF8&s=lawn-garden&pf_rd_p=1561971862&pf_rd_s=center-3&pf_rd_t=1401&pf_rd_i=1000999281&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0NW4MTFZ2MTFRK2V8DDG It's supposed to be an "aeroponics" system but the sprayers are shit and the roots really just sit in the water like DWC. Here is what i'm thinking i need: http://www.wormsway.com/detail.aspx?t=prod&sku=SDA270 and 6 of these: http://www.hidhut.com/alita-375-sintered-air-stone-disc-p-124.html?osCsid=01454cedb4611e3622c2a8dae432f2fd According to what i've read those are the best air stones and a very good pump. my system usually has about 15-20 gallons of water in them so i figure if i put one of those in each bucket it will provide enough aeration. ANY ADVICE IS WELCOME my plants are really struggling, they've been suffering from root rot off and on their entire life. I know i need a better system but they are too far in at this point to get a better system, the roots are too tangled, so i need to improve this system the absolute best i can for the time being, please please please please please help me.
