No worries, I tore all that crap down. I hooked up a pump and pull the nutes in and push them out with valves and it takes me about 10 minutes. You know it may just be your numbers hold. I've talked to alot of people about this, unlike me they're smart, educated in physics, biochem etc. and 30 plus years in hydro etc. and it doesn't make any sense to them. Of course this is their opinion. Glad it works for you and I appreciate your help that you continued to offer but you are the only person I can find on the infamous world wide web that it works for. Take care!
