I don't see it that way. We were looking at the information given and expressing ideas. My ideas are no better than my growing, and my growing isn't better than some of the folks running into problems. I just had a short run because I didn't notice a cheap thermometer measuring my canopy temp was off by 13ºF. Doh! I am happy to share my bad experiences to help others from having the same problems. I'm still trying to figure it all out but after screwing around with pH measurements I'm hard core on using a quality meter and necessary calibration chemicals and brand name pH up/down. Its too inexpensive to do it right but it is expensive to do it on the cheap.
